Can firecrackers bloom in winter? how can firecrackers spend the winter / control water and fertilizer?

Winter is a difficult time for most plants. Most plants go into dormancy and do not bloom in winter, but there are very few flowers that can produce beautiful flowers in winter. Can firecrackers bloom in winter? How do firecrackers spend the winter? Next, the editor will take you to learn about it.

Can firecrackers bloom in winter? yes

Second, how to spend the winter with firecrackers and control water and fertilizer

1. Temperature management

When we breed firecrackers in winter, it is best to breed them indoors, because the outdoor temperature is low and the plants are prone to frostbite. When we breed indoors, it is best to keep the indoor temperature above 10 degrees, so that firecrackers can survive the winter better.

two。 Watering management

Firecrackers spend in the winter, although the requirements for water and fertilizer are not very high, they still need proper wealth and some water and fertilizer, which will be helpful to the growth of plants in the coming year, but they must pay attention to the right amount when applying water and fertilizer, and do not apply too much. In order to avoid causing fertilizer damage, after all, the demand of the plant itself is not very great.

3. Light management

Firecracker flowers are cultivated indoors during the winter, but there can be no lack of light. when the temperature rises at noon every day, we need to move them outside to receive several disappearing light, so that they can carry out photosynthesis. it can also enhance its cold resistance, so that it can better survive the winter.

4. Environment management

When raising firecrackers in winter, we usually keep them indoors, but the environment should be properly ventilated and should not be too closed, otherwise it will easily lead to some diseases and insect pests in the plants, which will do great harm to the plants. so we should pay attention to this.

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.

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.
