Elaeagnus is a plant growing in East Asia. Its plant shape is natural, and its red fruit is drooping. It is suitable for grass planting. It is also used for natural hedge at the edge of forest and the periphery of trees. At the same time, it is also one of the common family potted plants. So how is Elaeagnus angustifolia cultivated? Let's look down together!
Cultivation method of Elaeagnus angustifolia potted landscape (basic knowledge): the best breeding time: sowing in the middle and late May; Cuttings are mostly carried out in March in spring, or in summer;
The best growing soil: Elaeagnus angustifolia is not strict on soil, it can grow on neutral, acid and calcareous soil, it is resistant to drought and barren, but not waterlogging;
Growth humidity requirements: Elaeagnus like warm and humid environment;
The best growth temperature: Elaeagnus has strong cold resistance, can overwinter in the open field in the south of North China, can endure the absolute low temperature of - 8 ℃, the suitable growth temperature is 24-34 ℃, and can endure high temperature and heat;
The best growth light: Elaeagnus is not afraid of sunlight, but also has strong shade tolerance.
Cultivation methods of Elaeagnus angustifolia matters needing attention in cultivation of Elaeagnus angustifolia: fertilizer application:
In spring, the fertilizer was applied once a month, stopped in Meiyu period, and was topdressing with potassium dihydrogen phosphate before fruiting.
In autumn, the fertilizer should be applied once every half month, mainly with phosphorus and potassium fertilizer, such as bone meal, superphosphate, etc., to promote the flowering and fruiting. In winter, the cake crumbs were used as base fertilizer.
Watering points:
Elaeagnus angustifolia is resistant to both humidity and drought, so it should be well watered. However, it should be watered only when the basin soil is completely dry. If it is watered thoroughly, the basin soil should not always be wet, so it is easy to rot the root system and is not conducive to growth. The basin soil should be dry and wet to grow well.
Pruning tips:
Elaeagnus angustifolia has a strong ability to sprout and shoot. Under the conditions of suitable environment and good water and fertilizer, it is easy to sprout and grow branches, which disturbs the appearance of the tree. It should be pruned in time, and the buds can be picked to control the growth.
Basin soil replacement:
Elaeagnus angustifolia should be turned every 3-4 years, preferably in early spring or after autumn.
The hardened old soil should be replaced by 13 ~ 12 loose and fertile culture soil, and a layer of vermiculite or coarse sand should be placed on the bottom of the basin to facilitate drainage.
Breeding points:
Elaeagnus is mainly propagated by sowing and cutting. The seeds can be harvested in time after the fruit ripens in May, and sown in time after sun exposure and threshing. The best nursery soil is sandy loam with loose soil and good drainage, combined with soil preparation, basic fertilizer application and soil disinfection. After sowing, cover it with fine soil, and then cover it with straw and water once.
From June to August, it is necessary to build a shed for shading, strengthen water and fertilizer management at seedling stage, and transplant and change beds in the next year. It is better to carry out cutting in March in spring than in summer. Spring cutting should choose the last year's strong branches as cuttings, with a length of 8-10 cm. Remove the lower branches and leaves, and leave about 2-4 leaves on the upper part. Cut the lower incision, soak it in 50 ppm NAA solution, take it out 24 hours later, and then cut it. After cutting, water it timely. In summer, shelter should be built to keep the soil moist.
Summer transplanting should be carried out in May to June in the plum rain season. The semi lignified spring shoots of the year were selected as cuttings, about 10 cm long, with heel, and about 2-4 leaves. The cuttings were quickly soaked with 500 ppm NAA solution, and the insertion depth was about 12. The surrounding soil was compacted and watered with fingers, and then the canopy was built to keep the soil layer B moist and easy to survive. The transplants could be carried out in the next spring.
Pest control:
Elaeagnus angustifolia has strong disease resistance, occasionally has red spider, scale insects and other insect pests. It can be sprayed with 1000-2000 times 40% dimethoate emulsion to control red spider. Scale insects are usually removed by manual brushing, and can also be controlled by dimethoate emulsion. Spraying should be carried out under strong light at noon, and attention should be paid to spraying the back of branches and leaves.
