How to raise paulownia flowers, breeding methods and precautions of paulownia flowers / avoid stagnant water / avoid bright light

Paulownia flower is a kind of flower plant native to tropical America, which was introduced to China and can be seen in many cities in China. However, it is not easy to raise it well. There are many things we need to pay attention to. How to raise paulownia flowers? What are the breeding methods and matters needing attention of paulownia flowers? Next, the editor will take you to learn about it.

First, how to raise paulownia flowers and understand their habits

If we want to know how to raise paulownia flowers, we must first understand its growth habits. This plant likes a warm and humid environment and prefers light, so we should keep it in sufficient light when raising it. In addition, we should also pay attention to the daily water and fertilizer management. As for the specific breeding methods are described in detail below, let's take a look.

II. Culture methods and matters needing attention of paulownia flowers

1. Sandy loam

When we cultivate paulownia flowers, we first need to choose soil, which is a step to lay a good foundation and is very important. Generally speaking, it is best to choose loose and fertile sandy loam, which has good drainage and strong air permeability. can let the plant better absorb nutrients, but also not easy to appear basin soil stagnant phenomenon.

two。 Fertilize, once a month

Fertilizer is one of the main nutrients in the growth process of paulownia flower, especially after entering its growth period, its demand for fertilizer is very high, basically every other month, so that the plant can thrive. When fertilizing, we should pay attention to the application of thin fertilizer, the fertilizer concentration must not be too high, otherwise it will burn the plant.

3. Moisture, avoid stagnant water

Paulownia flowers like to grow in a warm and humid environment, so we should frequently water them to keep the soil moist so that the plants can grow better. However, there is one thing we should pay attention to when watering, that is, remember not to accumulate water, because this plant is not resistant to waterlogging, if stagnant water will cause its roots to rot.

4. Light, avoid strong light

Paulownia flowers prefer light, but are not tolerant to strong light. If the light is relatively mild in spring and autumn, we can keep it outside and let it receive light all day, but after entering summer, because the light is relatively strong, we still have to shade it properly so as not to burn the plant.

5. Timely treatment of diseases and insect pests

When we cultivate paulownia flowers, if we are not careful enough, we are very prone to diseases and insect pests, and this kind of problem is very harmful to the plants, so we must deal with it in time after it is discovered, because the more it takes off, the greater the harm to the plants. as for the specific treatment methods, you can refer to the article on pest control of paulownia flowers, which has detailed maintenance teaching.

Erythrina variegata Linn. Picture guide of paulownia: how to raise paulownia / how to reproduce paulownia Erythrina variegata Linn. Introduction of paulownia culture methods and matters needing attention paulownia is native to the coral reef coast of tropical Asia and Pacific islands. It is the city flower of Quanzhou and Miyako Island City of Japan and the prefectural flower of Okinawa Prefecture. "Xitong City" is another name for Quanzhou. Taiwan's Karmalan people celebrate the Chinese New year with napas when it is in full bloom. Paulownia is produced in tropical Asia and is widely cultivated in South China and Sichuan. Like strong light, require high temperature, humid environment and well-drained fertile sandy loam, avoid wet clayey soil. Not cold-resistant, potted in the north, the winter temperature should be kept above 4 ℃. Deciduous trees, ca. 20m tall, dry bark gray, with conical prickles. Ternate compound leaves alternate, leaflets rhombic or rhomboid-ovate. Raceme, calyx flamelike dark red, butterfly-shaped, bright red, florescence March. The pods are beaded and the seeds are red. Paulownia tree tall and straight, luxuriant branches and leaves, sexual like strong light, otherwise poor flowering, the annual flowering, bright red flowers, flowers shaped like chili peppers, each inflorescence is like a bunch of ripe red chili peppers. Paulownia is produced in tropical Asia and is widely cultivated in South China and Sichuan. Like strong light, require high temperature and humid environment and good drainage of fertile sandy soil, avoid wet clayey soil; not cold-resistant, winter temperature should be kept above 4 ℃, the north is often ornamental in greenhouse pot. Paulownia flowers are colorful, suitable for garden ornamental trees or street trees, the north can be potted in the greenhouse, it is the national flower of Argentina. Paulownia flower is the city flower of Quanzhou City, Fujian Province. As early as the Middle Ages, Quanzhou was famous for its tung city in Europe, Africa and the Middle East. Because there are many tung flowers growing in Quanzhou in ancient times, it is known as "Caulownia City" or "Tongcheng". Quanzhou, with its picturesque scenery and picturesque scenery, was praised by the ancients as "the beauty of mountains and rivers is the most in the southeast." As early as the Southern Dynasty in the 6th century, Quanzhou was already an important port for China's trade with overseas. Since the Tang Dynasty, it has become more developed and is known as the four major commercial ports in China with Yangzhou, Mingzhou (Jinshan Islands and other places) and Guangzhou. In the Yuan Dynasty, Marco Polo thought that Quanzhou Port was more prosperous than Alexandria Port in Egypt. Quanzhou Port was also known as "Sitong Port". There are allusions that Quanzhou takes paulownia as its city flower. It is said that in order to expand the city wall of Quanzhou, the festival envoy of the five dynasties once planted paulownia all over the city. Later, paulownia grew with luxuriant flowers and red flowers, which became a major feature of Quanzhou, which made Quanzhou famous at home and abroad. Therefore, the paulownia flower has become a symbol of Quanzhou and is designated as the flower of Quanzhou. Its moral is: prosperous, auspicious and rich, full of people's good hopes for the future. The people of Quanzhou love paulownia flowers and regard them as "auspicious trees". Scholars and poets of all ages have also left many good lines reciting paulownia flowers. There is a poem saying: "when I first saw that the branches were green and thick, suddenly the fire army wanted to burn empty." The magnificent sight of paulownia blossoms can be seen. At present, there are many paulownia flowers planted in Kaiyun Temple and overseas Chinese Building in Quanzhou City, and the beautiful Quanzhou City is hidden in the green leaves and red flowers of paulownia. The morphological characteristics of paulownia paulownia is a large deciduous tree, up to 20 meters high. The bark is grayish brown, the branches have obvious leaf scars and short conical black straight thorns, the pith is loose, and the decadent part becomes a cavity. Pinnately compound leaves 3-foliolate, often densely branched; stipules lanceolate, caducous; petiole 10-15 cm long, usually unarmed; leaflets membranous, broadly ovate or rhombic-ovate, 15-30 cm long and wide, apex acuminate and obtuse, base broadly cuneate or truncate; basal veins 3, lateral veins 5 pairs; petiolule base with a pair of glandular stipules. Racemes terminal, 10-16 cm long, with dense, paired flowers; total pedicel woody, stout, 7-10 cm long, pedicel ca. 1 cm long, tomentose; calyx spathelike, 2-3 cm long, mouth oblique, one side dehiscent; Corolla red, 6-7 mm long, flag oval, 5-6 cm long, ca. 2.5 cm wide, apex round, petal stalk short; wing and keel nearly equal in length Keel 2 free, stamens 10, monomer; ovary puberulent; style glabrous. Pods swollen black, thick, interseed slightly constricted, 15-30 cm long, 2-3 cm wide, slightly curved, apex sterile; seeds 1-8, reniform, ca. 1.5 cm long, ca. 1 cm wide, dark red. Flowering in March and fruiting in August. The main characteristics of this species are prickly black; Calyx spathelike, oblique, divided to base, not 2-lipped, keel petals separated, keel nearly as long as wing petals; seeds red. Deciduous trees, 10-20m tall, dry bark gray, with conical prickles. 3 leaflets, rhombic or rhomboid-ovate. Racemes, butterfly-shaped flowers, bright red, calyx flamelike dark red, florescence 2-3 months. The pods are beaded, the seeds are dark red, and mature in September. The ecological habits of paulownia are common near trees or near sea streams, or planted in parks. This flower is native to India and Malaysia, with strong sex, strong germination and fast growth. when it blossoms, the new shoot can be up to 1.5 meters long, and the inflorescence is up to 50 centimeters long. it likes a warm, humid environment with sufficient light, drought and moisture tolerance, and is not strict with the soil. Xuan fertile sandy loam with good drainage; not very cold-resistant. Planting in the open field in Nanjing area can survive the winter with a little mulch, but the potted plant is safe only when it is placed in the greenhouse. Like strong light irradiation, flowering every March, like to the sun and improper wind growth, anti-wind is weak, can resist pollution, the growth rate is general, not cold-resistant, slightly shady. The cultivation technology of paulownia requires that paulownia is suitable for the environment with plenty of sunshine, high temperature and good ventilation; it should be dry and wet, but not waterlogging. Not cold-resistant, in late October, the overwintering temperature should be kept at about 15 ℃, not less than 4 ℃, and moisture should be controlled. It is resistant to barren and lax on soil. In pot cultivation, hoof horn film can be used as base fertilizer, bean cake liquid fertilizer can be applied every 2 Mill every 3 weeks, and thin fertilizer can be applied frequently. In open field cultivation, young trees should be pruned to form a round tree shape. Potted plants should choose larger pots, and large vats can be used for greenhouse potted plants. The roots of paulownia have a high degree of Lignification and few fibrous roots, such as poor drainage or stagnant water in basin soil, which is easy to rot roots, so loose and fertile sandy loam should be used as culture, and clayey soil with poor drainage should be avoided. When potting or changing pots, generally medium plants should use 100g / 150g hoof horn tablets as base fertilizer per pot. From May to September, mature organic liquid fertilizer should be applied every semimonthly. Paulownia does not like flood, and it is better to keep it half-dry and half-wet in the basin soil. High temperature in summer, large evaporation, can be watered once a day. In the hot summer, it is necessary to keep the outdoor semi-shade place for maintenance. In winter, water can be watered every 2 to 3 days. Plants that are trimmed before entering the house can be watered every 10 to 15 days. The aged plants should be cut off properly to facilitate the adjustment of plant shape. For the over-long branches, the heart-picking method can be taken after flowering to control the branch growth, or the flowering branches can be cut off from the base, and the budding branches bloom more luxuriantly. Change the basin every spring. Cultivation points paulownia in spring and autumn cut branches, length 10-15 cm, hotbed sand insertion, after shading, pay attention to watering and moisturizing, it is very easy to take root and form seedlings. Greenhouse potted plants need to use large pots, spring and summer require sufficient water, ventilation and light. Excessive heat should be cultivated in a semi-shady place. Liquid fertilizer was applied every two weeks from May to August. Watering should be controlled in winter, and the basin soil can be moist. The old plants should be properly cut off, and after reproducing branches and leaves, the pot management of paulownia should be adjusted, but the pot should be turned every other year before leaving the house, and the pot soil should be mixed with 2 parts of pond mud, 1 part of compost and 1 part of Hui bran ash. The plant needs to be re-cut, leaving only 1-2 buds for annual branches less than 1 cm in diameter, and 2-3 buds for those with a diameter of more than 1 cm. After heavy cutting, it will stimulate hidden buds and axillary buds to produce strong new shoots, which can make the trees blossom when they grow up. The mulberry branches and weak branches in the root should be peeled off in time. Give plenty of light after leaving the room. There is a little shade in the height of summer. Watering is based on the principle of wetting between dryness and dryness. After pulling out the new shoots, apply cake fertilizer and water every 10 days. After flowering, in addition to normal fertilization, phosphorus and potassium fertilizer was applied twice to promote the development and enrichment of branches. Fertilization was gradually stopped after October. After entering the room at the end of October, put it in a sunny place to keep the basin soil slightly moist. The breeding method of paulownia is suitable for warm climate, likes sunshine and is not resistant to cold. Multi-use cutting propagation, sowing or cutting propagation, cutting in April-May, 1-2 months can be root; can also be propagated under high pressure. Cuttings were selected from 1 to 2 years old in April, and the fully growing and robust branches were cut into 12~20cm branches as cuttings and inserted into the sand. After insertion, you should pay attention to watering and moisturizing, which is very easy to take root and survive. Seedlings should be placed in a semi-shady place and always keep the basin soil moist. When red buds grow on the cuttings, it means that they have taken root. The seedlings survived by cutting can be planted on branches in the following spring. The varieties of paulownia are classified into about 50 species, of which E.coralodendron, E.carffra, E.varie-gata and E.arborescens are commonly cultivated. Paulownia is distributed in Taiwan, Fujian, Guangdong, Guangxi and other provinces and regions. Native to coastal forests from India to Oceania, most of them are planted inland. Malaysia, Indonesia, Cambodia, Laos and Vietnam are also distributed. Paulownia is native to tropical Asia, namely India, Malaysia, and is cultivated in Fujian, Guangdong, Guangxi, Hainan, Taiwan, Zhejiang, Guizhou, Sichuan, Jiangsu and other places in China. It is the national flower of Argentina, Tonghua City, Jilin Province, China, Quanzhou City, Fujian Province, and Okinawa Prefecture, Japan. The role of paulownia ornamental value there are many daily functions of paulownia, it is suitable for planting alone next to grasslands or buildings, can be used for parks, green spaces and scenic spots to beautify, but also an excellent street tree for highways and city streets. The use value of paulownia wood is white and soft, and it can be used to make clogs or toys. The dietotherapy or medicinal value of paulownia the medical information and health dietotherapy information of paulownia are for reference only and can not be used as the basis of diagnosis and medical treatment.

Medicinal value paulownia bark or root bark is used in medicine, which is called paulownia bark, dispelling rheumatism, relaxing tendons and collaterals, treating rheumatism numbness, waist and leg muscles and bones pain, falling injury, relaxing striated muscle and calming central nervous system. However, it has the effect of accumulation, and the toxicity is mainly manifested by the inhibition of myocardial and cardiac transmission system. Bark contains alkaloids hypaphorine (C14H18O2N2), erythraline (C18H19O3N), beteine (C5H11O2N), choline (C5H15O2N) [2] sexual flavor leaves, bark and roots can be used as medicine, with antipyretic and diuretic effects. Bitter, bitter, flat. Anti-inflammatory, antipyretic, dispelling wind, promoting dampness and relieving pain. Paulownia is a poisonous plant listed in Chinese plant atlas database, and its toxicity is stem bark poison. The petroleum ether extract of 5g/kg stem bark in mice showed disappearance of righting reflex and muscle relaxation, which lasted for 4 hours, and decreased activity, writhing and eyes closed 3 minutes after intraperitoneal injection of 21g/kg and twig water extract. The symptoms of dizziness, lethargy and general weakness occurred after intramuscular injection of 30g stem bark extract in adults. 10-20mg/kg can cause spasm in rats and mice, and 5mg/kg can prolong the sleep time of barbital sodium in rats. It has neuromuscular blocking effect, smooth muscle relaxation and central nervous system inhibition. Rats with total alkaloids were injected intraperitoneally with LD50 as 127.8mg/kg. Pharmacological action Haitong bark water extract (1:3) had different inhibitory effects on Trichophyton blue, Xanthophytes xanthophyllum, Trichophyton rusts, Trichophyton inguinalis and other skin fungi in the test tube. Paulownia bark also had inhibitory effect on Staphylococcus aureus in vitro. Medication taboos 1, blood deficiency is not suitable to take. 2. "Classic of Materia Medica": it is not suitable for those with low back pain and non-rheumatism. 3. "Huiyan of Materia Medica": dysentery, red eye and arthralgia are not suitable for those who are not related to rheumatism. 4. "must be matched with Materia Medica": it is prohibited if the blood is less and the fire is hot. The garden use of paulownia is suitable for planting alone on grasslands or buildings, and can be used for beautifying parks, green spaces and scenic spots. It is also an excellent street tree for highways and city streets. Beautiful flowers can be planted as ornamental trees. This species grows rapidly and can be used as a pillar of pepper. The cultural background of paulownia is the national flower of Argentina, the city flower of Quanzhou and Miyagoshima City of Japan, and the prefectural flower of Okinawa Prefecture. There have been many poems about paulownia flowers since ancient times, and paulownia flowers can also be used for external use to stop bleeding. According to the Records of Foreign bodies, "Cangwu is a paulownia tree, and there are many things in Lingnan, because of the famous county." Because of the popularity of paulownia, Quanzhou is known as "Caulownia City" in ancient times, and Wuzhou in Guangxi has many paulownia trees, so it is named after Cangwu, which is also another name for Tainan City. Taiwan's Karmalan people celebrate the Spring Festival with napas flowers in full bloom. The clock records the passage of time, but have you ever heard of using paulownia to time? Paulownia was once regarded as a sign of time by people in some places. For example, there are historical records that more than 300 years ago, the compatriots of the Pingpu people in Taiwan did not have a calendar or even age, and could not tell 04:00. Instead, they took the paulownia flowers on the mountain as a year and lived a carefree life. Sunrise and sunset, flowers blossom and thank for another year. Such a natural and beautiful clock with a simple taste of the country, but also the totem in people's hearts. Customs in the old customs in some parts of China, people used to predict the annual growth by the situation of paulownia blossoming: if the flowering period of the first year is too late and the flowers flourish, then they think that there must be a bumper harvest and prosperity of six animals in the coming year, otherwise the opposite; there is also a saying that paulownia sprouts first and then blossoms every year, then its year is abundant, otherwise vice versa. Therefore, paulownia is also known as "Ruitong". It represents good luck. Because of this, there was a small debate in the Song Dynasty. On one side of the argument is Ding Wei, who came to Quanzhou as a cheap visitor. he very much hopes to see the green leaves of paulownia first to make the grain of Quanzhou rich, so he wrote such a poem: "people in the countryside say that paulownia is rich, and Ye Xianhua is rich in years." So far, I am worried about the people. I only love Qingqing rather than red. " The other side of the argument is Wang Shipeng, who came to Quanzhou as a county warden. He shares the same wishes as Ding Wei, but he does not believe in the prophecy of flowers or flowers before sprouting. To this end, he also wrote a poem: "at first sight, the branches were green and thick, and suddenly I was surprised that the umbrella was about to burn empty." Flowers are ripe year after year, but people don't like red when they don't know how to do it. " Although there is an argument, it is a good story that has been spread around the world. What a lovely public servant. Lovely flowers. It is said that this may have something to do with an old local legend: a long time ago in Argentina, many areas were often flooded, but it is strange to say that as long as there is a paulownia, it will not be flooded. Therefore, people regard paulownia as the embodiment of the god of protection, widely cultivated everywhere, and further promoted it as the national flower. The related poems paulownia flower King Hub Nanguoqing and Yanyuchen, paulownia flowers bloom on the road. The red clouds of the forest tops are rotten, don't feel the spirit in summer. Ying Ying fights against fire and deceives the hibiscus, and the perching crane flies with wings and worries. It is suspected that the Qing Emperor is in a hurry to clean up the spring breeze. Quanzhou paulownia flower song and Zhao Zhijun Chen Tao seems to plant three plants in the world, the scenery is full of idleness. There is no reason to look at strange trees with candles, and Liu Gong is drunk with Yushan. Haiqu spring is full of county clouds, and there are many kinds of paulownia flowers in Yue people. Poor tiger bamboo west building color, brocade account three thousand A mother's house. The golden garden of Shi Shi is not so gorgeous, and the old fu in Nandu is lack of spiritual materials. Just because of the tree in Chidi Palace, the new title of Danfeng was born. In the sunny day, the wind smiles more and more sweetly. It's just that the red can't be moved, and the paulownia barrier is all over the city. Unable to climb the melancholy years, the mangrove south sees the end of the sea. When the spring breeze of the old country is gone, who can send a flower? The Red Emperor often heard of traveling on the sea. Three thousand buildings were built to support Yanzhou. Today, the tree seems to leave the palace, red and green slanting to the 12th floor. The ten friends of the king of paulownia flowers first saw that the branches were green and thick, and suddenly the umbrella was about to burn empty. Flowers spend first and then rain year after year, but people don't like red when they don't like it. Ci Zhaojun complained about Tonghua-Liu Sikui a tree paulownia break. Kanai Xiaohan is kind. The hairpin blossoms at people. Feng flew back. The light moon is as hazy as snow. Dream of the pretence season. Wu Zi is not coming back. The moss falls. The city flower of Quanzhou as early as the Middle Ages, Quanzhou was famous for its tung city in Europe, Africa and the Middle East. Because there are many tung flowers growing in Quanzhou in ancient times, it is known as "Caulownia City" or "Tongcheng". On October 29th, 1986, the 11th meeting of the standing Committee of the 10th Municipal people's Congress decided that the paulownia flower should be the city flower of Quanzhou. The national flower is also respected by the world abroad. Argentines generally like paulownia and regard it as the national flower. The flower language of paulownia: red and red, auspicious and rich. Conservation measures of southern plant sea jujube in paulownia pictures

Bamboo taro

Bamboo taro is an herb. Most varieties have underground rhizomes or tubers, leaves solitary, larger, ovate or ovate-lanceolate, veins pinnately arranged, distichous, entire. Amorphophallus is a good ground cover plant with various colors and a good foliage plant. Amorphophallus is a tropical plant that likes a warm, humid and brightly lit environment, is not cold-resistant, is not resistant to drought, and is afraid of hot sun exposure. If direct sunlight will burn the leaves, the edges of the leaves will be partially scorched, the new leaves will stop growing, and the leaves will turn yellow, so we should pay attention to shading. Bamboo taro is sensitive to water, so it should be fully watered during the growing period to keep the basin soil moist, but the soil should not accumulate water, otherwise it will lead to root rot and even plant death. Bamboo taro should be more "delicate". Enough care should be put into 365 days, and if there are major fluctuations in the environment in a few days, it will leave "evidence of guilt" on the plant, which is the consensus of taro seed dealers and producers. There are not many diseases and insect pests in bamboo taro family, such as shell insects, whitefly and so on. Of course, it has other values, such as medicinal value and dietary value. Bamboo taro powder is almost entirely starch, does not contain vitamins, and contains only 0.2% protein. It can be used as a thickener for soups, sauces, pudding and tails. Add water and boil to make a transparent, odorless, delicious paste. Compared with other starches, the fine quality of taro powder can be cooked at lower temperature and shorter time, and it is easy to digest. It is especially suitable for making egg products such as milk and egg paste that can not be overcooked. It is also suitable for making light, low-salt and low-protein food. Efficacy: clearing lung and relieving cough, clearing heat and diuresis. Main treatment: treatment of cough due to lung heat and acerbity in urination due to damp-heat of bladder

Redrlowered Loropetalum

Evergreen shrubs or small trees. Bark dark gray or light grayish brown, much branched. Twigs reddish brown, densely stellate hairy. Leaves leathery alternate, ovoid or elliptic, 2-5cm long, apex mucronate, base round and oblique, asymmetric, stellate hairs on both sides, entire, dark red. Carthamus tinctorius likes light and is slightly shade-resistant, but the leaf color is easy to turn green when it is shady. Strong adaptability and drought tolerance. Like warmth and withstand the cold. Strong sprouting and branching, resistant to pruning. It is resistant to barren, but it is suitable to grow in fertile, moist slightly acidic soil.

In landscaping, it is widely used in lakeside, streams, both sides of roads and parks, etc., in small-scale greening projects such as courtyard greening embellishment, private gardens, etc., as well as potted ornamental plants, and often used to cut flowers and make bonsai. It is also common to weave branches and green peaches. The landscaping of Bitao has a wide range of uses, and the greening effect is outstanding, and the planting year has a particularly good effect. Can be planted, piece planting, isolated planting, there was a very good green effect in that year. Green peach is one of the commonly used color seedlings in landscaping, which is usually used together with purple leaf plum, purple leaf dwarf cherry and other seedlings. Flowers and shrubs are planted to form a scene of a hundred flowers blooming. In addition to the ornamental value, there is also medicinal value. The gum secreted on the trunk of the peach tree, commonly known as peach gum, can be used as an adhesive. It is a kind of polysaccharide substance, which can be hydrolyzed to produce arabinose, galactose, xylose, rhamnose, glucuronic acid, etc., which is edible and medicinal, and has the effect of breaking blood, promoting blood and tonifying qi. Diseases often occur in summer and autumn. The main diseases are: White rust and brown rot, perforation, anthrax, gum disease, leaf shrinkage disease. The main pests are aphids, red spiders, shell insects, red-necked longicorn beetles and so on.

Part II: "maintenance Plan 4"

Maintenance and management scheme of landscaping

Maintenance and management is very important in landscaping, it is a long-term and repeated work, with comprehensive technical requirements, including the destruction of people and animals, sanitation and cleaning, pruning of flowers and trees, watering and fertilization, pest control, flower bed flower planting and so on. The completion of garden green space does not represent the completion of the garden landscape. People often say that "three minutes, seven minutes". Only with high-quality and high-level maintenance and management, the landscape can be gradually formed and perfect.

Characteristics of the present situation of plants in the cultivation park:

1. The greening covers an area of about 2.45419 billion square meters, and the green coverage rate is high. There are a large number of different specifications and varieties of trees and trimmed shrubs, and their initial growth has gradually taken shape. After our careful investigation, the characteristics of plant planting are roughly divided into two areas according to the original general plan:

1) Square area: the plant planting style in this area is relatively open, with ginkgo biloba, Zhengnan and large trees in the square.

Plant mainly, properly cooperate with low shrubs, the overall space is more transparent.

2) Factory area: the plant varieties in this area are complicated, worn by large and small trees, shrubs and ground cover plants.

Planted in front of the door with more valuable large plants (Canary jujube, blue flower, small leaf banyan pile head

The best sweet-scented osmanthus, etc. Whether it can still keep the office garden elegant, elegant and sparse?

The scenery, can also make the hotel villa courtyard to carry forward its delicate and gentle, leisurely and relaxing atmosphere

It all depends on the acquired maintenance.

two。 In the greening condition of the vertical area, we can find the following problems: the growth of ① shrubs is poor and the shape is monotonous; the potential of ② flowering shrubs is poor, and the flowering condition (including the number of flowers, flower size, color, secondary flowering) is not satisfactory; there are many weeds in ③ lawn, and there is a tendency of grass weeds in some areas; there is a situation of diseases and insect pests in ④.

1. We are prepared to take the following rectification measures:

1. Carry forward three-dimensional horticulture and shape hedges and shrubs. For flowering shrubs planted with embellishment, measures should be taken to promote their growth and shape according to the trend, which depends on the specific plant growth and plant shape. The hedges in the local area are highly regular, and the uniform strip undoubtedly makes the garden which should be free and leisurely mechanical and rigid. We can also try to trim it into a wavy shape, match it with the relaxed and leisure residential landscape, enliven the atmosphere of the whole garden and create a more fluent living environment.

2. Immediately start the prevention and control of diseases and insect pests. For plants with the characteristics of diseases and insect pests, large-scale chemical control should be carried out immediately.

3 、

4 、

5. Apply pesticides and increase the workload of manual pulling for lawn weeds. Different maintenance and management schemes were implemented for different plants (mainly fertilizer supply, base fertilizer, topdressing, foliar fertilizer, different plants have different fertilization methods and fertilizer choices in different seasons). Plants are listed. We classify all the plants, and then make a green sign to mark it.

All the plants in the area are listed for their families, genera, and living habits. This can be done.

Enrich the staff's plant knowledge, can also add to the cultural atmosphere of the park, and can be marked with eye-catching

Make greening get more attention.

6. greening and maintenance is not an overnight thing. While doing a good job in rectification and reform, we will also be right.

The same plants take different maintenance measures at different times, and we arrange our daily work month by month.

(the detailed rules are attached), in order to maximize the landscape effect in the blueprint.

We also ask Party A to put forward more suggestions to make our work perfect step by step.

7. Maintenance responsibility

During the contract maintenance period, our company organizes reasonably and carefully maintains according to the operation rules and quality standards of landscaping maintenance, and dispatches professional horticulturists to organize and arrange the management and protection work, and flexibly dispatch not less than experienced workers according to the weather and plant growth conditions of each season to complete the maintenance and management tasks in quality and quantity.

B, sprayer, bucket, bamboo dustpan

C, shovel, hoe, saw, chainsaw, ladder

D, fuel, maintenance costs

3. Maintenance content:

A, Arbor: apply organic fertilizer once a year, 0.25 kg cake fertilizer per plant, once topdressing, 0.1 kg compound fertilizer and mixed urea per tree, hole application, spraying, water and fertilizer, etc., and then covered with soil, drenched thoroughly, water penetration depth of more than 10 cm, timely prevention and control of diseases and insect pests, maintain the natural growth state of trees, without modeling and pruning. Timely cut off yellow branches, disease and insect branches, shade long branches and drooping branches that hinder the passage of vehicles, and clean up the pruning materials in time. Remove weeds around the roots once a week to make sure there are no weeds.

B, shrubs, hedgerows, bag seedlings: fertilize once a quarter, apply urea mixed compound fertilizer 10 kg per 667m2, use sprinkling and water fertilizer, etc., water once within three hours after application, once a day (except rainy days), water penetration depth of more than 10 cm, timely prevention and control of diseases and insect pests, trimmed into a circle, square line or cone line, weekly minor repair, monthly overhaul, cut smooth, beautiful, timely removal of trimmed objects Cut off dead branches, disease and insect branches in time, replant old and dead plants in time, and remove weeds once a week.

(2) the specific arrangements for the maintenance of gardens in one year:

January: the coldest month of the year, with open-field trees dormant.

1. Winter pruning: fully carry out the shaping and pruning of deciduous trees; pruning dead branches, disabled branches, disease and insect branches on large and small trees and branches that hinder overhead lines and buildings.

2. Inspection of street trees: check the situation of binding and piling of street trees in time, and rectify them immediately when they find that they are loose, lead wire embedded skin, shaking piles and so on.

3. Pest control: winter is a favorable season to eliminate garden pests. The pupae and cocoons of the diamondback moth can be dug up and burned to death in the loose soil under the tree. Scale insects begin to move in mid-January, but they move slowly at this time, so we can scrape off the larvae on the tree trunk. Pest control in winter often has twice the result with half the effort.

4. Green space conservation: green space, flower beds and other places should pay attention to picking out large weeds; lawns should pick grass and cut edges in time; attention should be paid to anti-freezing watering in green space.

February: the temperature is higher than the previous month, and the trees are still dormant.

1. The maintenance is basically the same as in January.

2. Pruning: continue pruning withered and diseased branches of large and small trees. Trim all kinds of trees before the end of the month.

3. Pest control: continue to control diamondback moth and scale insects.

March: the temperature continues to rise. after the middle of the year, trees begin to sprout and some trees (such as camellia) blossom in the last ten days.

1. Planting trees: spring is a favorable time to plant trees. After the soil is thawed, we should seize the opportunity to plant trees immediately. Plan and design before planting large and small trees, dig (plane) a good tree hole in advance, and do as you dig, transport, plant and water. When planting shrubs, they should also be dug, transported and planted, and fully watered to improve the survival rate of seedlings.

2. Spring irrigation: due to spring drought, windy and large evaporation, green land should be watered in time in order to prevent spring drought.

3. Fertilization: after the soil is thawed, base fertilizer is applied to plants and irrigated. {maintenance measures of southern plant sea jujube.

4. prevention and control of diseases and insect pests: this month is the critical moment for the prevention and control of diseases and insect pests. Some seedlings appeared coal fouling disease, melon seeds and yellow poplar leaf roller also appeared (using spraying fenitrothion and other pesticides for control). The method of digging pupae can continue to be used to control diamondback moth.

April: as the temperature continues to rise, trees sprout and blossom or spread their leaves and begin to enter a period of vigorous growth.

1. Continue to plant trees: in the first ten days of April, we should seize the time to plant trees that sprout late, remove and replant shrubs (rhododendron, safflower, etc.) that die in winter, and fully water newly planted trees.

2. Irrigation: continue to water the green space in a timely manner.

3. Fertilization: combined irrigation of lawns and shrubs, topdressing available nitrogen fertilizer, or foliar spraying as needed.

4. Pruning: cut off the dry branches in winter and spring to trim the evergreen hedge.

5. Prevention and control of diseases and insect pests: (1) after the second molting, scale insects gradually transferred to bark cracks, tree holes, trunk base, wall corners and other places to secrete white waxy cocoon pupation. Can be swept with a hard bamboo broom, and then concentrated deep burying or soaking. Or use the method of spraying fenitrothasone and other pesticides. (2) the longicorn beetle begins to move. You can use a grafting knife or self-made steel wire to remove the larvae, but the smaller the wound, the better. (3) Prevention and control of other diseases and insect pests.

6. green space conservation: pay attention to the picking of weeds and climbing plants in large green space. Grass picking and edge cutting should also be carried out on the lawn.

May: the temperature rises sharply and the trees grow rapidly.

1. Watering: trees need a lot of water when they are in full bloom, so they should be watered at the right time.

2. Pruning: pruning residual flowers. The street tree is pruned for the first time.

3. prevention and control of diseases and insect pests: continue to catch longicorn beetles. The first generation of diamondback moth hatched, but it has not reached the degree of harm, so the corresponding measures should be taken according to the actual situation in the conservation area. Coal fouling disease caused by scale insects and aphids has also entered a peak period (on crape myrtle, Haitong, oleander, etc.). In mid-and late May, 10-fold pine resin mixture and 50% trithiophos emulsion 1500-2000 times were sprayed to control diseases and kill pests. (other available pesticides such as insecticides, Huabao, etc.)

June: the temperature is high

1. Watering: plants need a lot of water, so they should be watered in time, not "watching the sky to eat".

2. Fertilization: combine loosening soil and weeding, fertilization and watering to achieve the best effect.

3. Pruning: continue to peel off buds and remove tillers from street trees. Pruning hedges, balls and some flowering shrubs. {maintenance measures of southern plant sea jujube.

4. Drainage work: when there is heavy rain, we should pay attention to the drainage work in low-lying areas.

5. Prevention and control of diseases and insect pests: when the diamondback moth enters the peak incubation period in mid-and late June, timely measures should be taken. Now 50% fenitrothion emulsion is basically sprayed with 500-800 times liquid. (or sprayed with compound BT emulsion) continue to capture longicorn beetles by hand.

6. Do a good job in the inspection in front of the flood prevention platform for trees, and straighten, reinforce and re-bind the trees that are loose and inclined.

July: the temperature is the highest, and there will be strong winds and heavy rain after the middle of the year.

Street trees: carry out anti-Taiwan peeling and pruning, trim all branches that are in contradiction with electric wires, and check the stumps one by one, and immediately straighten and tie them up when they are found to be loose and unstable. Prepare the labor organization, materials, tools and equipment in advance, and send someone to inspect it at any time to deal with the dangerous situation in time.

5. control of diseases and insect pests: continue to control longicorn beetles and diamondback moths. To control longicorn beetles, 50% fenitrothion 1:50 liquid injection can be used to control longicorn beetles, (or Guoshubao, or Yuanke No. 3), and then seal the hole, which can also achieve good results. Cinnamomum camphor nest borer should be cut off in time and the nest should be destroyed so as to avoid further harm.

August: it is still the rainy season

1, drainage: after heavy rain, the low-lying water should be drained in time.

2. Taiwan prevention of street trees: continue to do a good job of Taiwan prevention of street trees.

The harm of aphids and camphor nest borer should be controlled in time. Attention should be paid to powdery mildew and rot in wet weather, and timely measures should be taken. September: the temperature has dropped, welcome the National Day to do a good job of related work.

1. Pruning: greet the appearance of the city and peel the buds below the third-level bifurcation of the street tree. Hedge shape trimming. Weeding in the green space, cutting the lawn edge, cleaning up the dead trees in time, so that the trees have green branches and green leaves, and the green space is clean and tidy.

2. Fertilization: for some trees whose growth is weak and the branches are not full enough, some phosphorus and potassium fertilizer should be applied.

3. Prevention and control of diseases and insect pests: perforation disease (cherry blossom, peach, plum, etc.) was the peak, and 1000-fold solution of 500% carbendazim was used to prevent infection. Longicorn beetles began to turn to root damage, pay attention to the capture of root longicorn beetles. The wood beetle moth on poplar and willow should also be controlled in time. Do a good job in the prevention and control of other diseases and insect pests.

4. Do well the inspection of all kinds of greening facilities before the festival.

October: the temperature drops, the early winter begins in late October, and the trees begin to shed their leaves and enter the dormant period one after another.

1. Be prepared to plant trees in autumn. As soon as the leaves of a hardy tree fall, you can start planting.

2. Green space conservation: timely removal of dead trees and timely watering. The work of picking grass and cutting the edge of green land and lawn should be done well. Fertilizers should be applied if the grass flowers do not grow well.

3. Control diseases and insect pests: continue to catch root longicorn beetles. Camphor nest borer should also pay attention to observation and control. November: the soil begins to freeze at night and enters the middle of winter.

1. Tree planting: continue to plant hardy plants and complete the soil before freezing.

Part 8: cultivation and Conservation of Palm plants

Palmaceae is a very characteristic evergreen plant in Monocotyledon class, its stem is solitary or tufted, erect or climbing; leaves gather at the top of the stem, developed roots, drought tolerance, barren tolerance, strong resistance to diseases and insect pests, excellent effect in creating tropical landscape style. This edition will introduce its introduction, transplanting and disease control.

Brief introduction of introduction process

There are about 2400 species of palms belonging to 183 genera in the world, which are widely distributed in tropical and subtropical humid areas of the world. High temperature and high humidity are important conditions for the normal growth and development of most palm plants. a few palm plants have a unique ability to adapt to adverse environment, such as silver jujube (wild jujube) distributed in extremely arid areas on the edge of the desert. and many palm species that can endure flooding for a long time, such as swamp palm. Most palm plants are rich in fiber, tough stems, well-developed roots, and strong wind resistance, such as false betel nut and sunflower.

Since the 1940s, the landscape effect of palm plants has been recognized in the construction of many tropical and subtropical cities around the world, and they have been used as key varieties for urban greening and beautification, such as Miami in the United States, Jakarta in India, Bangkok in Thailand, and Cape Town and Singapore in South Africa.

Some garden companies in Guangdong began to introduce and apply palm plants since the early 1980s. Over the next two decades, southern provinces such as Guangxi, Fujian and Yunnan, as well as Jiangsu, Zhejiang, Shanghai, Chongqing and Yunnan, have successively set off an upsurge of introduction, production and application of palms.

According to the theories of plant geography and ecology, several units headed by Guangdong Palm Garden Company observed and studied the growth and mortality of introduced and domesticated palms. It is found that the plants originating from the northern hemisphere generally have the potential of cold tolerance because of the ancient glacial climate, while the species native to high latitudes and high elevations in the southern hemisphere also have strong cold tolerance. Through the study of cold tolerance and cold tolerance mechanism of palm plants, researchers found that the main factors affecting introduction and domestication are temperature, light, humidity, moisture, soil and so on. The most significant role of temperature factor is to dominate the growth and development of plants, and low temperature in winter is the dominant factor affecting the success or failure of palm introduction and domestication; through the study of salt tolerance and shade tolerance of palms, researchers have selected a number of varieties with strong salt-alkali tolerance and shade tolerance; at the same time, through the prevention and control of diseases and insect pests such as palm Phytophthora, coconut leaf beetle and red palm weevil, the incidence of palm diseases and insect pests has been greatly reduced. In addition, the researchers also studied the mechanism of palm seed germination, summarized and invented the technology of palm seed germination, and mastered the techniques of full crown transplantation and large container seedling cultivation of palm plants. and effective work has been done on soil improvement, cold protection and conservation in winter.

At present, researchers have selected and popularized about 80 species of palm plants in South China, including Dawang coconut, sunflower, palm bamboo, southern coconut, fish-tail sunflower, and so on. More than 10 species of palm plants have been successfully applied in Shanghai and its surrounding areas, such as Budi coconut, Washington palm, Canary jujube, Washington coconut, and so on.

Take Washington Brown as an example.

Discussion on the occurrence and control of Phytophthora

Harm and general symptoms of Phytophthora palmiti

The disease is often harmful to palm plants such as coconut, sunflower, Washington brown, old sunflower, Canadian jujube, etc., the heart leaves of the diseased plant can not erupt normally, the new leaves shrink and wither, and in serious cases, the whole plant wilts. The pathogen of Phytophthora is caused by Phytophthora and can be identified by incubator. The pathogen overwintered mainly in the soil or on the remains of diseased plants. Germs spread through watering, rain splash, air flow and so on.

Incidence regularity of Phytophthora in Washington

The disease occurred during the period of high temperature and humidity in summer and autumn. Poor management before drought and rain or after transplanting, such as pouring water, soil water content

Plants that are suddenly elevated, poorly ventilated, or located in the tuyere are susceptible to disease. The disease is serious in low-lying, poor drainage and continuous cropping land. In addition, the disease is often related to serious root injury caused by digging seedlings and long-distance transportation.

When it occurs, the base of the undeveloped young heart leaves rot, and the leaves are grayish green and drooping, which can be pulled out with a little effort. Dissecting the stem, it can be seen that there are paste secretions and foul smell in the growing point and even the heart of the whole plant, and white mildew can grow in the susceptible tissue. Seriously affected plants often suffer from root damage, and the main symptoms are blackening and rotting of the roots.

Taste. The disease mainly occurs in the seedling stage and nursery, and the adult trees planted on the green space rarely occur.

Symptom

In recent years, the damage in the nursery is quite serious. At the initial stage of the disease, the yellowish-brown watery spot occurred near the ground, the spot expanded rapidly, slightly sunken, the surface was dense white cavernous mold when it was wet, and the disease part rotted and smelly. When the disease occurs on the leaves, the diseased part is yellowish brown and white mildew grows under wet conditions. When the disease occurred on the stem, it was dark green at first, then expanded, moist and softened, and the upper part of the stem withered in the later stage. The disease can harm the whole palm plant. Sometimes the roots and stems are cut open with purulent fluid exudation, and in severe cases, the veins of young leaves have a large number of gray-black mycelia. Phytophthora is a vascular bundle disease. In severe cases, the whole plant wilts, droops and dries up to death, and the mortality rate is high.

According to the investigation, the peak period of the disease is the period of high temperature and humidity, that is, the optimum temperature is 27 ℃ to 35 ℃. For example, in 2006, the onset period in the coastal areas near the Pearl River Delta was from July to October, from August to November in Xiamen, from June to September in Shanghai (also in early spring), and from August to November in the mountains in the western Pearl River Delta. However, the disease can be seen in all parts of the country from January to February after typhoon and rainstorm. Sometimes sporadic, sometimes in patches.

Prevention and cure method

1. Prevention of cultivation measures

1. Pay attention to the ventilation, dryness and drainage of the nursery, trim the leaves appropriately in autumn and winter every year, and dig holes and cultivate the soil to keep the nursery dry. Potassium fertilizer can be applied at ordinary times, quicklime and superphosphate can also be applied respectively to enhance plant tissue density and infection resistance and improve plant disease resistance.

two。 To select a good plot, it is necessary to choose loam or sandy loam land with high topography and good drainage for planting.

3. Rotation is implemented, requiring rotation for more than three to four years on land that has been planted with Washington brown.

4. Strengthen field management, increase the application of organic fertilizer, promote plant growth, deep roots and leaves, and improve resistance. Carry out high ridge (border) cultivation. Proper control of watering in the rainy season, timely drainage after rain, so that the rain is dry; timely watering in case of drought, flooding is strictly prohibited during watering, and carried out in sunny afternoon or evening.

5. Give priority to prevention and comprehensive prevention. Usually pay attention to observation, often prune dead branches and leaves, find diseased plants, clean them up in time, bury them deeply or burn them, and disinfect the diseased points with lime.

II. Chemical control

One or two months before and during the onset of summer, 64% alum wettable powder (1 ∶ 500 to 600), 80% aluminum ethyl phosphate (1 ∶ 400), or other dioxin, such as carbendazim, that is, Tushuxiao (common dosage is 600 to 700 times), stone sulfur mixture (1 ∶ 1 ∶ 100), dioxone (500 times), etc. Specific prevention and control methods: when transplanting Washington brown, first spray the planting site and Washington brown roots with 600 to 700 times solution of soil bacteria, or dig a pit to sterilize in the sun on a continuous sunny day, or sprinkle lime powder to disinfect, or disinfect the soil with 500 times solution of dimethazone.

After the typhoon, timely spray disinfectant alum (better) or ethyl phosphate aluminum (easy to produce drug resistance), add 0.4% washing powder to heart or spray prevention and treatment. It can also be sprayed with 80% mancozeb 700 times solution, once every 7 to 10 days, even two or three times, which can effectively prevent and control the occurrence of Phytophthora. After taking this measure, the incidence of Washington Brown and Mao Washington Brown in the Shanghai base of Guangdong Palm Garden Company has dropped from 20% in 2004 to less than 10%.

Experience of prevention and treatment

The control effect of carbendazim is not obvious. At the initial stage of the disease, if all the leaves are cut off and transplanted elsewhere, about 30% of the plants can be revived one after another after 2 to 3 years, but the growth is poor.

It is understood that the disease rarely occurs in high-temperature and dry areas such as Los Angeles, so the disease is related to high temperature and humidity, and it is infected through surface water, groundwater and Rain Water. When the roots, trunks and leaves of the plant are damaged, the bacteria invade and multiply in large quantities when the water is sufficient, which eventually leads to the blockage of vascular conducting tissue and the loss of water and wilting and death of the plant. In fact, the heart rot introduced in the literature is also Phytophthora, but it occurs in the heart lobe.

The disease is different from anthrax, which occurs in leaves, appears watery spots, and then expands into larger spots, which is easy to be found. generally, carbendazim and other agents can be used for prevention and treatment. As for leaf spot disease, it refers to the disease on leaves, the common pathogens are leaf spot mold, Alternaria, and so on, which often cause leaf blight, but anthracnose and leaf spot rarely cause plant death. Technique of transplanting large seedlings of single stem

Preparation before transplantation

l. The roots of the seedlings to be transplanted were cut in advance, the size of the soil ball was twice the diameter of the ground, and the depth of the roots was 50 cm to 60 cm. The broken root soil should be backfilled in time after removing stones and broken roots, and do a good job of moisturizing: the purpose is to calcine the adaptability of seedlings and tend to grow new roots. After cutting the root, it is best to retain it for more than 30 days, and not transplant until the new root begins to germinate. If the use of false planting seedlings, the effect is better.

two。 Dig holes and prepare for ploughing. The planting site is burrowed 20 days before transplantation, and the size of the hole is generally 1.5 times that of the earth ball. When the burrowed soil is exposed to the sun in the open air for a period of time, it is best to use pre-prepared mixed soil: pond mud + farm manure or mushroom soil + appropriate amount of mature phosphate fertilizer + appropriate amount of river sand, sand ∶ mud is 4 ∶ 6.

Planting time

The Pearl River Delta region can be transplanted throughout the year, preferably in spring and autumn, and try to avoid summer and winter, especially in January and July. Palm plants mostly like temperature and humidity, the summer air temperature is high, and the seedlings evaporate quickly, which is easy to cause too much water loss and affect survival; in winter, the temperature is low, there is even frost in some places, and the strong north wind is easy to cause frostbite or even freeze to death of seedlings.

Transplanting seedlings

The stem of some single-stem palm seedlings is thicker, the workload of transplanting is heavy, and the seedlings are easy to be injured, so it is necessary to use gunny bags or straw to cover the trunk, especially the green trunk at the boundary between the trunk and petiole. One is to protect and expand the tree trunk, and the other is to moisturize and protect against the sun. In addition, the seedlings are combined with pruning leaves to remove old leaves and retain 40% to 45% of the leaves (depending on the strength of the tree). At the same time, cut off the leaf and petiole to reduce the evaporation of water.

Planting

The seedlings had better be planted on the same day. If the time is too long, the water evaporation of the seedlings is large, and it is easy to survive due to water loss. If you can't finish planting on the same day, cover it with a shade net and spray a small amount of water on the leaves every day to shade and moisturize.

1. Return to the soil to set the position of the seedlings, that is, to return to the soil. When you return the soil to half the height of the earth ball, the loose soil will be compacted first. After returning to the soil, the mound is made into a "water storage basin" with a slightly higher surrounding and a slightly lower middle to facilitate water retention and moisturizing.

two。 Immediately after dripping water back to the soil, immediately drench the root water, before dripping water, use bamboo sticks to insert the loose soil around the soil ball, until the loose soil no longer sinks.

3. There are many kinds of fixed supports, and the triangular support made of three bamboo poles is the most economical and practical one. The height of the binding is at 2 stroke 3 of the trunk.

Post-planting management

l. Moisturizing spray leaf and trunk bandage twice a day, except in rainy days, to spray wet leaf and trunk bandage. The roots are not drenched with water, because there is excess water flowing down, and the stagnant water causes rotten roots. Cover straw around the tree head to prevent the soil from hardening caused by excessive soil temperature difference, and keep the soil around the soil ball loose, moist and aerated, which is conducive to the germination of new roots.

two。 Fangfeng is generally tall because the large seedlings of single-stem palm plants are generally high, and they are often affected by thunderstorms and strong winds after transplantation, so it is necessary to regularly check whether the support is loose after planting, especially if you find that the trunk is tilted after the gale.

3. About a month after topdressing, urea water can be used as extra-root topdressing, spray, topdressing time about half a month. After the first new leaf is grown and ripe, dig holes and fertilize with fully mature peanut bran. The hole-digging position is outside the edge of the soil ball to open a circular trench with a width and depth of 30 cm, and the fertilizer and backfill should be mixed evenly.

4. Because of the relatively weak tree potential, the newly transplanted single-stem palm seedlings are extremely vulnerable to diseases and insect pests, especially young leaves and heart leaves. Insecticidal can be killed with 5% methamidophos and 5% omethoate. At present, the invasive pest "coconut leaf beetle" is very harmful to palm plants. Adults and larvae concentrate on the foliage of heart leaves that have not yet been unfolded, resulting in the death of some or all of the newly extracted leaves and slow growth of the damaged plants. even withered. There are the following prevention and control methods: ① 81% marathon emulsion 1000 times, ② cypermethrin 500x solution, ③ use of "coconut Jiaqing", can achieve a good control effect. According to the actual operation, the author thinks that the most simple, convenient and long-term method is to combine with binding "Coconut Jia Qing" to prevent and cure it on the heart leaves.

About a month after planting, palm science university seedlings can determine whether they survive according to whether their leaves remain green or not, but in order to really determine their survival, it is generally necessary to wait for a growing season and take whether they have sent out new shoots and roots as the standard. After the author adopts the above transplanting techniques, the transplanting survival rate is increased from 75% to more than 90%, and the above techniques are highly operational, so it is necessary to popularize and apply them.

Transplanting techniques of seedlings, big trees and clump seedlings

Key techniques of seedling transplanting

Palm plants are most suitable for transplanting within a period of time after they germinate and take root. At this time, the seedlings are small and can be transplanted with seeds. in addition, there are few whisker roots, so it is not easy to damage the roots when transplanting seedlings. Using nutrition bag to raise seedlings, the size depends on the time of cultivating seedlings. Generally speaking, it is appropriate to use 16 cm × 18 cm container for 1-year-old seedlings and 19 cm × 20 cm for 2-year-old seedlings. Too small nutrition bag is not conducive to the rapid growth of seedlings. Loose topsoil, burning soil and wheat bran were mixed with a small amount of phosphate fertilizer according to the ratio of 5 ∶ 2 ∶ 1, and then bagged. First put in half a bag of mixed soil and then release the seedlings, then straighten the seedlings and compact them, so that the roots of the seedlings are close to the mixed soil and drenched through water. Palm plants should not be planted too deep, otherwise the growth of seedlings will be affected. When it is too deep, the seedlings should be lifted up to make the roots of the seedlings expand.

Key techniques for transplanting big trees

Palm plants are cultivated in the nursery for 5 to 10 years, and most of them need to be transplanted in separate beds for several times, so sparse planting and strong seedlings are selected, and the survival rate is higher.

To reduce the damage to the root group, the root tissue of palm plants is young, and there are many lateral roots and capillary roots. When digging, they should take large soil balls as much as possible and prevent them from loosening and cracking. The course of root injury should be reduced to a minimum in order to maintain normal respiration and water absorption and improve the survival rate of transplantation. During the construction, the line should be accurately laid out and the hole should be determined to avoid overwork and prevent the soil ball from being loose.

The amount of leaves retained in leaf pruning and transplanting should be comprehensively determined according to different species, climate at the time of transplantation, transplantation and maintenance conditions.

Generally, about 40% of the original number of leaves should be retained. Too many leaves will lead to withered and yellow leaves due to large water evaporation; if there are too few leaves, the plant recovery is difficult and the cycle is long, and the initial landscape effect is not good.

In the process of digging, transporting, loading and unloading the stem and its pseudostem, the stem should be protected from damage, and the part of the pseudostem should not be squeezed and bent, which is the guarantee of plant health and rejuvenation as soon as possible.

Palm plants in the newly planted soil will damage the root tip during transplantation, and it is difficult to germinate new root tip within one month after transplantation, so the water absorption capacity is weak. At this time, good water permeability and air permeability of the soil is conducive to the survival of seedlings, so large holes should be dug and attention should be paid to the quality of guest soil, and peat soil and compound fertilizer should be added to facilitate recovery after palm planting.

Maintenance within one month after planting, the adaptability of the plant is poor, to deal with the careful maintenance of seedlings, must be timely replenishment of water, proper shade, and strive to make it have new leaves to sprout within three months. If there is a rainy climate for several consecutive days after transplanting, palm seedlings will recover better because they can avoid the influence of adverse factors such as hot sun on rainy days.

Key techniques for transplanting large-scale clustered seedlings

The tufted species of Palmaceae have multiple growing points and can grow new roots more quickly after transplanting. However, tufted palms also have some disadvantages, such as large water evaporation due to trunk weight and large leaf area, and being vulnerable to strong winds because of poor air permeability. Therefore, in addition to the disposal according to the transplantation of dry palms, the following technical measures should be added:

1. After the implementation of the "hairy root method" transplantation, after digging up the larger soil balls, use a small shovel to remove part of the soil along the outer edge of the soil balls, retain more fibrous roots and moderate soil balls, and immediately outsource moisturizing lightweight materials to reduce the weight of the soil balls and ensure survival. For example, this method can be used for the transplantation of clump palms with slow recovery, such as fishbone sunflower and betel nut.

two。 The implementation of bare root pseudo-planting or pot planting concentrated maintenance until the new root germination, plant stability before formal planting. This method is suitable for rough tufted palms such as loose-tailed sunflower, strange wrinkle palm and Hawaiian coconut, which can reduce freight and facilitate construction.

In short, the transplantation of large seedlings and big trees of palm plants is to grasp five aspects, namely: selecting strong seedlings; digging soil balls and carefully transplanting seeds; moderately pruning leaves; doing a good job of ventilation and drainage of planting land; and sun protection and moisturizing after planting. The sign of the success of transplanting big seedlings and trees is that most of the leaves can be preserved and new leaves can be sprouted within half a year after planting, among which three healthy new leaves can be used as the complete success of the transplant.

Drainage: the hydrological condition of the planting land should be understood first, and the bottom of the soil ball should be placed at the position where the soil ball is 100-150CM above the perennial underground water level line and the soil layer is thick. at the same time, the underground soil ball root hydrophobic layer and the surface runoff drainage network should be done well to prevent the soil ball from accumulating water after planting. If the hydrological conditions can not meet the requirements, the method of throwing high soil balls can be adopted, that is, mixing fertile soil with loose medium or heaping high planting land with coarse sand to meet the above requirements as far as possible, and then placing the plant on the soil mound, and filling the soil ball with mixed loose soil or planting soil mixed with rot soil; remove debris from the soil around the planting site, or properly use loose medium to improve the soil, so as to achieve the condition of loosening and ventilating the root of the plant. Strengthen the inspection in the rainy season, dredge the drainage facilities and loosen the soil at the roots in time, so as to prevent waterlogging and drainage. Moisturizing: immediately after planting, the fixed root water should be irrigated to ensure that the root of the soil ball is moist and closely combined with the surrounding soil to promote the development of the root system, and then irrigate the soil ball three times in time to prevent the topsoil from cracking. In the hot summer, more water should be sprayed on the ground and canopy to increase the ambient temperature and reduce transpiration; the moisturizing treatment of the leaf surface includes: a, the newly planted seedlings should be properly built to reduce the transpiration area of the leaves; b, anti-transpiration agents should be properly sprayed on the leaves to inhibit the physiological metabolism of plants and reduce the physiological dehydration of plants. C. Under fine weather conditions, we should spray water to the leaves as much as possible, strengthen the water absorption of leaves and weaken transpiration; check the water status of soil balls and roots at any time and replenish water in time to ensure the moisture of soil balls and the permeability of root respiration. Fertilization: after planting, in addition to moisturizing the plant, foliar fertilizer with appropriate low concentration can be sprayed to strengthen the nutritional supplement after planting. Check the root germination status of the plant frequently, if it is found that the plant grows new roots, you can consider increasing root fertilization, generally choose the season when the monthly average temperature is higher than 20 ℃, apply organic fertilizer as much as possible, and properly apply compound fertilizer with high P and K content, so as to promote the nutritional balance of the plant and ensure its Shaanxi to restore healthy growth. Pest control: spraying medicine before the nursery comes out of the nursery, and after arriving at the construction site, it is also necessary to spray the plant before unloading, and to ensure that the plant is sprayed three times at intervals of one week to ten days after planting, and then it is necessary to formulate a reasonable pest control plan.

General situation of project

Shilien (Nanjing) Optoelectronics Co., Ltd. is located at No. 31 Hengfei Road, Nanjing Economic and technological Development Zone, with a green area of 28186 square meters. The greening plant configuration in the factory area is relatively reasonable, the color is rich, and the seasonal change is obvious, forming a hierarchical and natural ecological plant community, which basically shows the natural landscape of plants. The configuration of plant flowers, shrubs and hedges among factories makes each plant form different landscape styles. The factory has planted dozens of plant varieties, such as camphor, magnolia, beech, sweet-scented osmanthus, crape myrtle and so on, among which there are boulevards composed of camphor, ancient red maple, fruit pomegranate, Xifu begonia, ginkgo, Canadian jujube and other varieties.

In view of the existing situation of the greening landscape in the factory area, we think that the initial construction of greening is relatively extensive, and the understanding of plant habits is not enough, especially the replacement of planting soil in the greening land is not in place, and the garbage soil in some areas has not been replaced, resulting in poor plant growth.

Arrangement of greening maintenance plan

January (Lesser Cold, Greater Cold)

1. Fruit trees are shaped and pruned.

two。 Always pay attention to check cold-proof equipment, facilities and seedling cold-proof bandages.

3. Turn the land for winter ploughing and apply sufficient winter fertilizer.

4. Cut off the branches and leaves of withered, residual, disease and insect pests, and thoroughly remove the overwintering skin insect sac, stinging moth cocoon and latent overwintering insect pests.

February (the Beginning of Spring, Rain Water)

1. Continue to prune deciduous and fruit trees in winter.

two。 Continue to cut off the branches of diseases and insect pests, and pay attention to observe the occurrence of diseases and insect pests (such as cotton blowing scale, grass scale, etc.).

3. Continue to accumulate fertilizer and make compost, prepare culture soil, and continue to apply winter fertilizer to all kinds of deciduous trees. March (stinging, the Spring Equinox)

The weather is getting warmer and many diseases and insect pests are about to occur. It is necessary to maintain and repair all kinds of pest control and disease prevention equipment and prepare medicines. Pay attention to the occurrence of aphids and paramecium and control them in time. April (Qingming Festival, Grain Rain)

1. Do a good job in the prevention and control of scale insects, mites, ground tigers, aphid grubs, mole crickets and powdery mildew and rust.

two。 Do a good job of loosening soil, weeding, fertilizing before flowering and so on. Thin fertilizer should be applied to perennial root flowers and spring sowing grass flowers every week.

3. Do a good job of peeling and pruning trees. Remove superfluous buds and inappropriate branches at any time.

4. Dredge and repair the drainage system.
