Planting and management techniques of oak trees

Seed collection: when the fruit falls off naturally or shakes the tree can fall and pick up seeds from the ground. The 1000-grain weight is 3000-4500 g, and the germination rate of seedling seeds is high.

Sowing: can be sowed in autumn, winter and spring. Sowing in autumn and winter is carried out from November to December, and the seeds are generally sown with picking after maturity. Autumn and winter sowing can be used in areas where frost is not serious, and it accords with the characteristics of oaks. It also reduced storage, sprouted and unearthed early in the next spring, and the survival rate was higher than that of spring sowing. Spring sowing should be early to avoid seed germination and mildew of stored seedlings. Seedling seeds are often damaged by weevil, which can be treated by soaking seeds in 55 °warm water for 10 minutes before sowing. Oak tree is a mycorrhizal tree species, which needs to be mixed with fungus soil. Strip sowing was used with row spacing of 20 cm and seed spacing of 10 m. The sowing rate is 150-200 kg per 667 square meters. When sowing, the seedling seeds should be placed horizontally, which is beneficial to seedling emergence and rooting. After sowing, the soil can be covered with 3 meters of soil, which can also be covered with fungus soil to facilitate mycorrhizal development. The thickness of the covered soil should be the same, otherwise the seedlings will not emerge neatly.

Management: emergence of seedlings about 1 month after sowing. When the seedlings were unearthed, the young roots were already deep in the soil. In order to promote the formation of lateral roots, one month after emergence, the main root of the seedling was cut off with a shovel and watered in time after root cutting. The seedlings that cut off the main roots tend to grow slowly for a while. In the fast-growing period, both height growth and thick growth are faster, so fertilizer and water management should be strengthened. The oak tree is the whole growth type, and the coarse growth does not end until the beginning of November. The height of one-year-old seedlings can reach 40-60 cm.
