Third, the cultivation of Elaeagnus angustifolia precautions

1. seedling

Elaeagnus angustifolia seedlings are sowing seedlings and seedlings inserted.

Sowing seedlings: Sowing seedlings are mostly in spring. For spring seedlings, seed treatment should be carried out in December of the first winter. The method is to wash the seeds of Elaeagnus angustifolia, mix them evenly with equal amount of fine sand, put them into the seed treatment pit (80 cm deep, 100 cm wide, and the length depends on the number of seeds) dug in advance, or pile them on the ground according to the thickness of 40~60 cm, bury them with sand to form ridges around them, irrigate enough water (10~20 cm of accumulated water on the seeds), and after the water seeps down or freezes, cover them with sand for 20 cm to overwinter. The seeds that have not been stored in winter can be soaked in warm water at 50~60℃ for 2~3 days before sowing. After being taken out, they are mixed with horse manure and placed in the sun to moisturize and germinate. After 30~40% of the seeds are cracked, they can be sown. Seeds sown in autumn need not be germinated.

Cutting seedlings: selecting annual branches with good lignification, no diseases and insect pests and full lateral buds as cutting strips. The cuttings collected from the field are cut into cuttings according to the length of 15~20cm. The cutting angle is 45° or even truncated. When cutting, special attention should be paid to protecting the first lateral bud at the upper end of the cutting. The upper incision should be cut flat and cut at about 1cm above the first bud. The lower incision should be selected at the base of the first bud. Most of them are inserted in spring, but they can also be inserted in autumn. Spring planting should be early, generally before axillary bud germination, autumn planting before soil freezing.

2. Temperature and humidity: The optimum temperature for the rooting of Elaeagnus angustifolia is 20℃~30℃, and the relative humidity of the air must be maintained at 75~85% after the rooting.

3. Light: In Elaeagnus angustifolia inserted after the sun must be blocked off 50~80%, after the root growth, and then gradually remove the shading net. Remove the shade at 4:00 p.m. every day on a sunny day and cover it by 9:00 a.m. the next day.

3. Pruning: after the trees are covered, the sprouting branches at the roots should be removed, the lateral branches below 1/2 of the trunk and the upper lateral branches affecting the growth of the trunk should be pruned. Later, according to the growth potential of the trees, appropriate spacing, thinning, and pruning and shaping should be carried out.

4. pest management

Disease: Cinnamomum angustifolia brown spot disease is one of the important diseases of Elaeagnus angustifolia seedlings and young forests. The disease spots of Elaeagnus angustifolia grow on the leaves, and brown to yellow spots are formed on the front of the diseased leaves, which are small at first, 2~3mm, and gradually expand to 5~8 mm.
