How to plant primroses? Management skills of propagation and planting of primrose

According to the editor, the origin of the name of primrose is that it blossoms in spring and is very popular in daily life. Its planting method is simple and its reproduction ability is strong. The following editor will briefly introduce the breeding and planting management skills of primrose to you.

Primrose is cultivated in all parts of our country. Because of its strong adaptability to soil, drought tolerance, vivid plant appearance and pruning-resistant growth habits, primrose is widely used as greening materials for garden lawn, courtyard ornamental and soil and water conservation. Cuttage is the main method of propagation. Striping and split propagation can also be used. Let's take a look at the breeding methods of primrose.

Cutting propagation: spring, summer and autumn can be carried out, cut semi-lignified branches 12-15 cm long, inserted into the sand, keep moist, about 15 days to take root.

Strip propagation: the longer branches are shallowly buried in the sandy soil, do not need to be scratched, take root after 40-50 days, and separate and transplant from the mother plant in the following spring.

Ramet propagation: it can be carried out when the buds sprout in spring. When transplanting in spring, part of the aboveground branches should be amputated, and the lodging soil should be brought. It can also be dried, that is, after cutting in the whole seedbed, it can be filled with water. Cutting can be carried out from mid-October to mid-November or in spring.

Water insertion propagation:

1, time: can be carried out all year round, winter water container can be placed indoors to the sun, summer should pay attention to shade, to prevent the hot sun, water temperature should be maintained at 15-20 ℃, cuttings rooting fast, high survival rate.

2. Cuttings: cuttings choose branches with strong, full growth and full bud eyes in the current year. The length of cuttings is generally 8-12 cm, and 2-4 nodes can be left. The cuttings are cut flat at about 2 mm under the lowest section, and every 10 branches are tied into a bundle. If there are too many leaves in the upper half of the cuttings, they can be removed properly to facilitate rooting.

3. Containers: containers are large-caliber pots or shallow jars or glass jars, porcelain jars and other containers, which should be washed clean before use.

4. Method: fill the container with clean Rain Water, river or tap water, as deep as 8-10 cm, and then arrange the bound cuttings into the water with a depth of 4-6 cm. Then put the container in an outdoor ventilated and half-shaded place, and the water quality must be kept fresh and clean, and the water can be changed every 3-5 days. Generally, tumor-like healing tissue can be produced about 20 days after insertion, and fibrous roots can grow in about 35-40 days.

5. Cultivation: when the whisker root grows to 3-5 cm, it must be planted in time, pay attention to the operation carefully, do not damage the root system. Generally, after planting, shading treatment can be carried out for about 10 days, then normal management can be carried out.

The above is the breeding method of primrose, which can be collected by relatives who love flowers and plants.

It got its name because it blossomed earliest among the flowers, and then ushered in the spring of a hundred flowers. Together with plum blossoms, daffodils and camellias, it is called "four Friends in Snow". It is one of the most valuable flowers in China. Primrose is not only dignified and beautiful, extraordinary temperament, but also has the characteristics of fearless, no choice of style, strong adaptability, has always been loved by people. Spring branches droop, from late winter to early spring, the flowers are golden and the leaves are green. In landscaping, it should be arranged in lakeside, stream bank, bridgehead, wall corner, or in lawn, forest edge, sloping land, and around houses, which can be planted for viewing flowers in early spring. The greening effect of Yingchun is prominent, the embodiment speed is fast, and it is widely used in various places. Planting had a good greening effect in that year. Yingchun was used as an ornamental shrub in flower beds in Shandong, Beijing, Tianjin, Anhui and other places, and Shuyang in Jiangsu Province was the preferred producing area for Yingchun. The morphological characteristics of primrose deciduous shrubs, slender branches, arch-shaped drooping growth, plant height, up to five meters, is a common ornamental flower. Lateral branches robust, quadrangular, green. Ternate compound leaves opposite, 2-3cm long, leaflets ovate-elliptic, surface smooth, entire. Flowers solitary in leaf axils, Corolla goblet-shaped, bright yellow, apical 6-lobed, or compound. The florescence is from March to May and can last as long as 50 days. The ecological habits of primrose are light-loving, slightly shade-tolerant, cold-tolerant and afraid of waterlogging. They can survive the winter in open fields in North China and near Mianling County, Henan Province, requiring a warm and humid climate, loose, fertile and well-drained sandy soil, growing vigorously in acidic soil and poor in alkaline soil. The root germinates strongly. The landing part of the branch is easy to take root. The cultivation techniques of primrose can be cut in spring, summer and autumn. Cut the semi-lignified branches 12-15 cm long, insert them into the sand, keep them moist, and take root for about 15 days. By pressing, the longer branches are shallowly buried in the sandy soil without scratching, take root after 40-50 days, and separate and transplant from the mother plant the following spring. Ramets can be carried out when buds sprout in spring. When transplanting in spring, part of the aboveground branches should be amputated, and the lodging soil should be brought. In the process of growth, pay attention to the soil should not accumulate water and excessive drought, and fertilize properly 2-3 times before and after flowering. It should be pruned and reshaped in autumn and winter to keep many new flowers. Leaf spot and branch blight often occur in diseases and insect pests, which can be sprayed with 1500 times of 50% bacilli special wettable powder. Insect pests are harmful to aphids and coir moths, which are sprayed with 1000 times of 50% phoxim EC. Primroses are warm and hardy. The flowering period of Yingchun is affected by the temperature and blooms from the south to the north from late January to April. If you want to blossom during the Spring Festival, according to the size of the buds, you can move them into a sunny room of 12: 16 ℃ 2 weeks before the festival, more than 2 meters away from the TV set and air conditioner, water with a temperature similar to the room temperature once every 3 days, and often spray water to the branches and leaves. If the buds do not bloom a week before the festival, the room temperature can be raised to 20 ℃. After flowering, the room temperature should be controlled below 15 ℃, which can bloom for 30 days. It can also be dried, that is, after cutting in the whole seedbed, it can be filled with water. Cutting can be carried out from mid-October to mid-November or in spring. After rooting, it can be planted separately, and it can also be propagated by ramet or striping. The propagation method of primrose forms flower buds on annual branches in spring and blossoms from the end of winter to spring in the second year, so all flower branches should be cut short every year to promote the growth of more lateral branches, increase the number of flowers, and strengthen fertilizer and water management at the same time. The salmon seedlings with breast diameter above 2cm can be grafted at lm or at a certain height when they germinate in early spring. Yingchun branch Chang 8-10cm was used as scion for grafting. After that, tie it tightly with thin film, cover it with a plastic bag, and gradually tear the bag into a breathable and ventilated seedling after survival, and pick the heart to promote the extraction of side branches to cultivate the crown. The distribution area of primrose originated in northern China, mainly distributed in North China, Liaoning, Shaanxi, Shandong and other provinces. Primrose is more resistant to cold, like sunshine, drought but not waterlogging. Propagation is mainly divided into plants, striping and cutting. It is often used to decorate flower beds and decorate the courtyard. It is an important early spring flower. It is often cultivated in various places for ornamental use, and it is also distributed in the provinces of central and northern China. Leaf medicine, detumescence and detoxification, treatment of swelling, pain, sore, fall injury; flowers can relieve fever and diuresis, treat fever and headache, urination heat pain. Both leaves and roots contain eugenin and primroside. Propagate with cuttings or strips. The dietotherapy or medicinal value of primrose the medical information and health dietotherapy information of primrose are for reference only and can not be used as the basis of diagnosis and medical treatment. Any health problems should consult professional health care personnel, the treatment of any disease, please follow the doctor's advice. The ultimate task of protecting flowers: to love yourself, proceed from reality and follow the doctor's advice. For disease, do not be careless, do not postpone, do not give up hope, face it bravely, warm the silent world with love, and protect the inner flower field with your heart. Primrose can be used as medicine, mainly for fever and headache, urine heat pain, antipyretic sweating, diuresis; its leaves can promote blood circulation and detoxification, detumescence and relieve pain, mainly treat swelling and acne, fall injury, trauma bleeding, etc., commonly used in traditional Chinese medicine are: treatment of wind-fever cold, fever and headache: 15 grams of primrose, water decoction. Cure urination heat pain: primrose, plantain 15 grams each, water frying service. Irregular menstruation: 30 grams of primrose root, 15 grams of red orchid root, stewed pork. To treat abscess, malignant sore and nameless swelling poison: dry primrose at the end, take 6-9 grams of wine, or 30 grams of primrose or leaves, fried in water, or smash and apply the affected area with tender tips and leaves. Treatment of eczema: appropriate amount of primrose, fine powder, apply sesame oil to the affected area. Treatment of fall injury, knife wound bleeding: appropriate amount of primrose, smash the affected area, or use 15 grams of primrose leaves, water frying service. Treatment of vaginal trichomoniasis: primrose leaves, Sophora flavescens each appropriate amount, water decoction to rinse the vagina. Variety identification of primrose and forsythia belong to deciduous shrubs of Oleaceae, which are widely cultivated in various parts of China; they have many similarities: they bloom at similar times, yellow flowers, flowering first and then long leaves, therefore, many people can not well distinguish between the two plants. In fact, the difference between them is obvious, the details are as follows: 1) Yingchun old branches grayish brown, branchlets quadrangular, slender, arched growth, green. All the leaves are Ternate and grow symmetrically. The leaves are small, ovate-elliptic, entire, and the apex is narrow and pointed. Flowers solitary, yellow, saucer-shaped, placed in the axils of first-year branches. The forsythia branch is round, the branchlet is light brown, the stem is hollow, often drooping, the leaf is large, shaped to long oval, the upper part is neatly serrated, and the lower part is entire. Simple leaves or 3 leaves opposite, in which the parietal leaves are larger and the bilateral leaves are smaller. The flowers are golden yellow and the petals are wide. 2) the branchlets of Yingchun are green, while the twigs of Forsythia suspensa are darker, generally light brown. 3) the flower of primrose has 6 petals each, while Forsythia suspensa has only 4. 4) Primrose seldom bears fruit, while forsythia flower bears fruit. Primrose and wild jasmine are both shrubs of Jasminum in Oleaceae, which are also widely cultivated in China; they are very similar, but there are some differences: 1) Primrose is a deciduous shrub, flowering before leaves, leafless in full bloom. Ye Yingchun is an evergreen shrub with green leaves at flowering stage. 2) the kaleidoscope of primrose is long, while the kaleidoscope of wild jasmine is short. 3) the spring primrose in Xi'an blossoms earlier than the plum blossoms in the same area from the end of February to March. The florescence of wild Yingchun in Xi'an is usually in early April, about a month later than primrose and obviously later than plum blossom. Primrose and Yunnan Huangxin 1) Primrose belongs to deciduous shrub, while Yunnan Polygonum chinense belongs to evergreen shrub. 2) there are long leaves after flowering in the spring flower market, while the flowers and leaves appear at the same time in Yunnan Polygonum cuspidatum. 3) Yingchun originated in the northern and central provinces of China, and its cultivation is very common in North China, so it is also known as "North Yingchun". Phellodendron yunnanensis originated in the subtropical areas of South China and Southwest China, and its cultivation is very common in the south. It is used to be called "Nan Yingchun". Disease control of primrose mosaic disease [symptom]: whole plant disease caused by cucumber mosaic virus CMV. The symptoms are that the leaves become smaller and deformed, with dark green markings or yellowing. The infected plants do not blossom, or blossom, and the flowers are short and deformed with markings (see figure). The main route of transmission is peach aphid and cotton aphid. The main source of infection is the susceptible plants of surrounding weeds. [prevention and control methods]: first of all, weeds should be removed in time to reduce the source of infection. Secondly, aphids should be prevented and controlled as soon as possible to eliminate virus transmission vectors. [5] Brown spot disease [symptom]: it mostly occurs in the spring of the four seasons. It is caused by Alternaria of the subphylum Alternaria. There are brown spots on the leaves of infected plants. The route of transmission is that conidia are transmitted by wind and rain. [prevention and treatment]: spray 70% chlorothalonil wettable powder 1000 times liquid and other fungicides at the initial stage of the disease. Botrytis cinerea [symptom]: it is one of the common diseases of primrose, which occurs all over the country. After the plant was infected, the whole plant yellowed and withered. The disease mainly infects leaves, tender stems, floral organs and so on. It often occurs at the tip and edge of the leaf. At the beginning of the disease, the leaves appeared water-immersed spots, and then gradually expanded, turned brown and rotted. In the later stage, a gray-yellow mildew layer was formed on the surface of the lesion. After the stem was infected, the disease spot was brown and gradually rotted. After infection, the floral organ also became brown and rotted and fell off. Under moist conditions, a gray mildew layer appears in the disease, which is a major feature of the disease. The disease overwinters with sclerotia in the remnant and soil. The disease is easy to occur when the air temperature is about 20 ℃ and the air humidity is high. Spread through wind and rain, tools, irrigation water. In the greenhouse, the disease is the most serious in late winter and early spring. [control methods]: the planting density should be reasonable. Pay attention to ventilation and reduce air humidity. Diseased leaves and diseased plants are removed in time to reduce the source of infection. At the initial stage of the disease, 1500 times of 50% Sukeling or 50% Prohydantoin wettable powder was sprayed. It is best to apply alternately with 65% carbendazim wettable powder 500 times to prevent drug resistance. Spot disease [symptom]: mainly harms plant leaves. The disease spread from the lower part of the plant to the upper part. The spot is usually 3 to 4 mm in diameter, brown, and in severe cases, the diseased leaves die, resulting in fallen leaves. The disease is caused by Alternaria alternata. The pathogen overwintered on the diseased residue by mycelium or conidium, and the seeds could also carry bacteria, which became the source of initial infection in the second year. The disease is mainly spread by conidia in the air and Rain Water. Re-infection is frequent in the growing season. Plants are usually prone to disease in warm and humid weather and partial application of nitrogen fertilizer. The disease usually begins in July and is prevalent from August to October. [control methods]: select disease-resistant varieties, strengthen fertilizer and water management, increase application of organic fertilizer and phosphorus and potassium fertilizer, and avoid partial application of nitrogen fertilizer. At the initial stage of the disease, 70% methyl topiramate was sprayed with 1000 times solution plus 75% chlorothalonil wettable powder 1000 times solution, or 1 ∶ 1 ∶ Bordeaux solution. Leaf spot disease [symptom]: it often occurs on leaves and receptacles. At the initial stage, water-immersed irregular spots were produced along the leaf veins, then yellowed and browned, the lesions enlarged and the leaf margin dried up. In severe cases, it withered from the lower lobe. [control methods]: strengthen cultivation management, cultivate disease-free seedlings, the soil of seedling bed should be disinfected, and air should be released in time in greenhouse to reduce air humidity. Remove the remains of the diseased plant in time. After the attack, 50% copper succinate wettable powder or 72% agricultural streptomycin wettable powder 4000 times were sprayed. Common insect pests, aphids and coir moths. Control method: spray with 1000 times of 50% phoxim EC. Legends related to the cultural background of primroses A long time ago, the ground was flooded, crops were flooded, houses collapsed, and people had to gather on the top of the mountain. There is chaos between heaven and earth all day long, even the four seasons of spring and autumn can not be distinguished. At that time, the emperor was called Shun, and Shun asked the minister to lead the people to control the water. after several years, the water was getting bigger and bigger. When Han died, his son Yu took up the heavy burden of flood control. When Yu was leading the people to look for the waterway, he met a girl in Tushan who boiled water and cooked for them and helped them to point out the source of water. Dayu was grateful to the girl, who also liked Yu very much, and the two got married. Yu was busy with flood control, so they got together for a few days and broke up. Before leaving, the girl sent Yu one journey after another. When he came to a mountain, Yu said to her, "you have to make a difference when you send it." I won't turn back until I cure the water. " The girl looked at Yu with tearful eyes and said, "go, I will stand here and see you level the flood and come back to me." When Dayu said goodbye, he took off the girdle of Jingteng and handed it to the girl. The girl touched the vines belt and said, "go, I'll stand here and wait until the vines blossom, the flood stops, and people live and work in peace and contentment." When Dayu left the girl, he led people to visit Kyushu and dig the river. A few years later, the rivers were dredged, the floods returned to the sea, the crops were unearthed, the willows sprouted, and the people finally lived in peace. Dayu happily came back all night to find the girl he loved. From a distance, he saw the girl holding the bouquet of bauhinia vines in her hand, standing on the high mountain waiting for him, but when he looked at her, the girl had already become a stone statue. It turned out that since Dayu left, the girl had stood on this mountain and looked around every day. No matter whether it is windy or rainy or cold, he never goes away. Later, the awl penetrated her feet, and the grass seeds sprouted and took root on her, and she still looked around with her vines in her hands. Over time, the girl became a stone statue, her hands grew with the bauhinia vine, and her blood was soaked with the bauhinia vine. I do not know how long, Jingteng unexpectedly turned green, tender, and sent out new branches. Yu came forward and called for the beloved girl. Tears fell on the statue, and suddenly golden flowers blossomed on the vines. The bauhinia vine blossomed and the flood disappeared. In order to commemorate the girl's mind, Dayu gave the bauhinia vine a name "primrose". The related poem "playing with primroses as a gift to Yang Lang Zhong" Jinying Cui calyx with spring cold, how many yellow flowers are there? According to the words of the gentleman, he said to the visitors, Mo Zuo looked at the blue and white eyes. -- Bai Juyi Tang [brief introduction]: Bai Juyi (772-846), Han nationality, Lotte, Xiangshan Jushi, Xiagu (now northeast of Weinan, Shaanxi), is a famous poet and litterateur with far-reaching influence in the history of Chinese literature. he is known as the "devil of poetry" and "king of poetry". His poems were widely influenced in China, Japan, Korea and other countries, and he was the leader of the "New Yuefu Movement".

Picture of primrose planting method, how to make primrose reproduce better, how to plant a primrose in pot

The branches of primrose are graceful, and the flowers are bright and beautiful. In addition to planting in the courtyard and flower beds, you can also watch or make bonsai by potted plants. So do you want to plant primroses for viewing? Today we will talk about how to plant a primrose and how to make it reproduce better.

Potted plants to welcome the spring

Potted primrose is potted after defoliation in winter to before germination in spring. The pot soil should be watered thoroughly with loose and fertile sandy soil with good drainage and water retention, and preserved in a place away from the wind and the sun. Watering during the growing period should be "no dry, no watering, watering thoroughly" to avoid stagnant water in the basin soil, otherwise it will cause rotten roots. It is necessary to reduce watering after September in order to control the growth of branches and make them survive the winter safely. The rotten organic liquid fertilizer should be applied once or twice every spring to supplement the nutrients consumed by flowering and restore the plant growth as soon as possible.

The period from June to August is the flower bud differentiation period, which can increase the use of phosphorus and potassium fertilizer and pay attention to water deduction, which is beneficial to the formation of flower buds. Fertilization in autumn can increase the cold resistance of plants and promote the development of flower buds. Applying some fertilizer before flowering can not only make the flowers fat, but also prolong the flowering period. Turn the pot once after the flower fade in spring every year to 2 years. The basin soil can be mixed with garden soil, humus soil and sandy soil, and a small amount of mature cake fertilizer and livestock manure can be added as base fertilizer. And combined with changing pots to prune the plant, remove dry and withered branches, disease and insect branches, and pay attention to heart-picking during the growing period, so as to promote the plant to have more branches and maintain the perfection of the tree shape. If you need New Year's Day or Spring Festival flowering, you can move the seedling pot to the sunny place indoors 3 weeks in advance and keep it at a temperature of 15 ℃ to 20 ℃ to blossom in time. The flower branches of Yingchun are raised in water bubbles and can blossom in 5 to 7 days. It is an excellent material for cut flowers in winter.

The propagation of Yingchun can use a variety of methods such as ramet, striping and cutting.

Ramets are usually carried out in spring and autumn, but it is better before flower buds germinate in early spring. Striping or cuttage is usually carried out in about a week after the flower fade. When pressing the strip, first cut it with a knife in the cortex of the buried branch to facilitate rooting. Cuttings can be carried out in the hotbed or directly in the open field. Choose 2-year-old strong branches as cuttings with a length of 15 cm to 20 cm. Bury the branches of 1 stick 3 in the soil, keep the soil moist, and take root in 2 to 3 weeks. When the young roots change from white to yellowish brown, start transplanting. At the initial stage of seedling transfer, shade net or Reed curtain should be used to shade for 5 to 7 days, and the seedling rate is higher.

The primrose used to make bonsai can choose those plants that have grown for many years and have simple and vigorous roots. Most of them are transplanted from winter to early spring. They are first planted in mud pots to "raise blanks". Before planting, the plants are trimmed and shaped once, the branches and roots that are not needed in shape are cut off, and the long branches are cut short, and the roots cut off can be selected for cutting in good shape, and planted in small pots after survival. That is, to become a simple and elegant miniature bonsai, the soil should be well drained sandy soil to ensure survival. As primrose is a trailing plant, although the branches grow fast, there is no obvious trunk, and even thicker branches are difficult to find, so we can consider using the method of "replacing stem with root". The soil surface of the Qiu qu and colorful root is put forward to replace the tree trunk. Root lifting should be carried out step by step and should not be completed at once, otherwise it will expose too many fine roots of the plant, causing the stump to sprout back, and even the plant will die in serious cases. The shape of the root stem varies from tree to tree, and different forms can be used, such as single dry type, double dry type, oblique dry type, curved dry type, bridge type, root lifting type and so on.

The crown mostly uses the drooping branch type, its branches naturally droop, showing a waterfall shape, using the pruning method to make the branches dense and uniform, this form is the most common. Plum pile type, cut off the bent and drooping part of the branch, such as when the newly sprouting side branch is about to bend and sag, then cut off it, so that all the branches are linear, like a sparse and oblique plum blossom when blooming. Big tree type, choose Qiu qu old, trunk, main branch, side branch distinct plant, the branch flat pruning into a cluster, in the growing period looks like a big tree, but in fact the tree "leaf" is composed of dense twigs, because the material is difficult to find, this form is the most rare.

Primrose bonsai can reshape the plant before flowering, and the heart is often picked during the growing period, in order to make the branches thicker and increase branches, which is conducive to modeling, and the branches that affect the tree shape should be cut off in time to maintain the beauty of the bonsai. Other management is basically the same as potted primrose. Its common shape is the hanging branch type, which is characterized by natural drooping branches, smooth lines, blooming trees and flowers, warm and hot. Yingchun has strong adaptability, like light, cold tolerance, drought tolerance, alkali tolerance, fear of waterlogging, lax requirements on the soil, can grow in slightly acidic, neutral and slightly alkaline soil, but grows best in loose and fertile sandy soil.

Planting is usually carried out after flower withering or in mid-September. If you want to raise the root, you can raise the root appropriately when planting, but don't raise it too high at once, otherwise it will be harmful to the growth. Because the primrose is yellow, it is appropriate to choose the pot of light blue, purple and black when planting, so that the color of the pot and the flowers are in harmony. If cultivated properly, it will be full of yellow flowers in spring, green leaves in summer and autumn, green vines whirling in winter, and the four seasons are full of spring.

The above is all I know about primrose. I hope it will be helpful for flower friends to read this article. If you want to know more about woody flowers, please continue to pay attention to the succulent flower bed, we will provide you with more related knowledge!
