Ginkgo tree planting: how to fertilize ginkgo tree?

How to fertilize ginkgo trees? Please introduce that ginkgo biloba is a fertilizer-loving and fertilizer-tolerant tree species. The fertilization method should determine the period, quantity and times of fertilization according to the growth status of ginkgo trees, and apply fertilizer 3-4 times a year; detailed fertilization methods can be listed below: first, the method of applying spring fertilizer to ginkgo trees: young trees or adult fruit trees should be fertilized one month before Grain Rain, which can improve the fruit setting rate. If it is an adult tree, it should be fertilized in the second half of Grain Rain, and the amount of hanging fruit can be reduced appropriately. Fertilization is mainly quick-acting fertilizer, supplemented by organic fertilizer, generally bearing 50 kg of trees, need to apply 200 kg of manure and urine fertilizer; such as chemical fertilizer, nitrogen, phosphorus and potassium compound fertilizer is the best, 2.5-5 kg per plant, apply more big trees, and reduce the amount of small trees appropriately. Second, the method of applying summer fertilizer to ginkgo trees: it should be applied sooner rather than later in early July. This period is a period of fruit growth, vigorous root growth and flower bud differentiation. Whether nutrients can be supplied in time is not only related to the yield of the current year, but also to the formation of flower buds and the yield of the second year. It is better to apply quick-acting fertilizer for long fruit fertilizer. 0.5 kg of urea can be poured on each tree. Be sure to add water and pour it. The concentration should be controlled at about 0.1%, and never exceed 0.2%. As it was in the hot and dry season at that time, it was generally not suitable for ditch application, because ditch application would cut off the absorbing roots of ginkgo trees and cause serious fruit drop. The concentration of fertilization must also be paid attention to, too high concentration is easy to cause fertilizer damage. If you encounter continuous dry weather after fertilization, you should also water it properly. Third, the method of applying autumn fertilizer to ginkgo trees: the seeds of ginkgo biloba are generally harvested from late September to the first and middle of October to before defoliation, and there is still a growing season of 1-2 months. The second growth peak of the root system can generally be seen after ginkgo seed harvest, and the flower buds that have been bred continue to develop, so postharvest fertilization can make up for the nutrients consumed by tree fruit, restore tree potential, and ensure high yield in the second year. When applied before the root growth peak, the absorption and utilization rate of fertilizer are also relatively high. The application of farm manure is the best, and ditch application is the best. The direction and depth of trenching can be changed appropriately, even if part of the root system is cut off, it will not affect the growth and fruiting of the plant. The amount of fertilization can be 3-4 times the annual yield, that is, the plant that produces 100 kg of ginkgo can apply 300-400 kg of fertilizer. Fourth, the method of applying winter fertilizer to ginkgo trees: before and after the Spring Festival every year, deep ditches should be opened and base fertilizer should be re-applied once. The base fertilizer takes soil miscellaneous fertilizer and cake fertilizer as the ideal fertilizer, and the ginkgo trees with sufficient nutrient fertilizer can apply little or no base fertilizer at this time.
