Suggestions on planting methods of jungle trees

Mainly sowing: sowing usually begins to bear fruit at the age of 20, with a large amount of fruit. Flowering in May, fruit maturity 9? 10 month

When the fruit is ripe, it will naturally fall off or shake the tree and pick up the seeds from the ground. A thousand grains weigh 3000? 4500 grams, the germination rate of seedling seeds is high. Seedlings sown in spring need to be stored in wet sand. That is, after seedling seeds are collected, they should be put in a cool place to dry, not exposed to the sun. Then, pure seedling seeds should be collected and stored in layers with 3 times of wet sand until sowing in the next spring.

sow seeds

Can be planted in autumn, winter and spring. Broadcast in autumn and winter 1 1? Will be held in February 65438. Generally, seeds will be harvested and sown when they are mature. Autumn and winter sowing can be used in areas where frost is not serious, which is in line with the characteristics of oak trees. It also reduces the storage capacity, germinates early in the next spring, and the survival rate is higher than that of spring sowing. Sow early in spring to avoid stored seedlings sprouting and mildew. Seedling seeds are often harmed by weevil. Before sowing, the seeds can be soaked in 55 1 warm water 10 minutes for insecticidal treatment. Quercus acutissima is a mycorrhizal tree species, which needs to be dressed with fungus soil. The row spacing is 20cm, and the seed spacing is10cm. The sowing amount per 667 square meters is 150? 200 kilograms. When sowing, the seedlings need to be placed horizontally, which is beneficial to seedling emergence and rooting. After sowing, the soil can be covered with 3 cm, or with fungus soil, which is beneficial to the development of mycorrhiza. The thickness of covering soil should be consistent, otherwise the seedling emergence will be irregular.

grow

Seeding seedling management-about 1 month after sowing. When the seedlings were unearthed, the young roots had been deeply rooted in the soil. In order to promote the formation of lateral roots, the main roots of seedlings were cut off with a shovel 1 month after emergence, and watered in time after root cutting. The growth of seedlings whose main roots are cut off will temporarily slow down. In the fast-growing period, high growth rate and coarse growth rate are faster, so it is necessary to strengthen fertilizer and water management. Quercus acutissima is a whole-period growth type, and the rough growth will not end until 1 1. The height of annual seedlings can reach 40? 60 centimeters. Transplanting after defoliation in autumn and before germination in spring. Pay attention to protect the root system when transplanting, and bring as many lateral roots as possible. Quercus acutissima cultivated by big seedlings is a tree species with strong apical advantage. When cultivating large seedlings, it is necessary to trim them in time, and the incision should be smooth, so as not to damage the bark or leave piles.
