Abstract

A method for prolonging the abscission period of ginkgo leaves is characterized by comprising the following steps: during the mature period of gingko seeds (from the last ten-day of September to the first ten-day of October) (1) loosening the soil around ginkgo tree roots, covering the ginkgo tree roots with soil or sand and the like, (2) removing the excessive branches on the periphery of ginkgo trees and overcrowded, thin and weak branches on the inner side of the ginkgo trees, and (3) spraying leaf fertilizer on the surfaces of the ginkgo leaves and pouring nutrient solution on the roots. With the method for prolonging the abscission period of the ginkgo leaves, the abscission period of the ginkgo leaves is prolonged effectively, the ornamental effect of the ginkgo leaves is improved, the abscission period can be prolonged for one to two months, the disease-resistant capacity of the ginkgo trees is improved, and the resistance of the ginkgo trees is enhanced.

Description

technical field [0001] The invention relates to the field of regulators for plants, in particular to a method for prolonging the defoliation period of ginkgo leaves. Background technique [0002] Ginkgo trees are tall and straight, with fan-shaped leaves. The crown is shade-shaped and has a cooling effect. The leaf shape is quaint and has a long lifespan. It has no pests and diseases, does not pollute the environment, and has smooth trunks. It is a famous pollution-free tree species, which is conducive to the reproduction of ginkgo and adds to the scenery. Strong adaptability, ginkgo has a wide range of climate and soil requirements. Anti-smoke, anti-fire, anti-toxic gas. Ginkgo trees are tall, with straight trunks and graceful postures. They are emerald green in spring and summer and golden in late autumn. They are ideal landscaping and roadside trees. It can be used as an ideal cultivated tree species for landscaping, roads, roads, field forest nets, and windbreak for...
