Maidenhair-tree winter anti-freezing method

Abstract

The invention discloses a maidenhair-tree winter anti-freezing method. The maidenhair-tree winter anti-freezing method is characterized by including the following steps that a maidenhair tree serves as a center, in the range of a circle of which the radius is 9-12 cm, a pit of which the depth is 12-14 cm is dug, and the bottom of the pit is leveled; prepared root anti-freezing nutrient gel is poured into the bottom of the pit to form a gel layer of which the depth is 0.2-0.3 cm, soil is used for covering the pit and leveled up; maidenhair-tree trunk is protected, firstly, a 8-mesh cotton web is adopted to wrap part of the portion, from the root part to a part which is 1.2-1.5 m away from the trunk, of the maidenhair tree, trunk anti-freezing nutrient gel is adopted to coat the portion, covered by the cotton web, of trunk, and the depth of a trunk nutrient gel layer is about 0.15-0.3 cm, then, limewater is used, and the portion, covered by the cotton web, of the trunk is painted to be white.

Description

Technical field [0001] The invention belongs to the technical field of antifreezing trees, and in particular relates to a method for preventing freezing of ginkgo trees in winter. Background technique [0002] Ginkgo is an ancient tree species. With its tall and straight, fan-shaped crown leaves, long life, pollution-free and pollution-free characteristics, it has become the first choice for family courtyards, gardens and urban greening. At the same time, ginkgo can be used as high-grade The raw materials for furniture, the flavonoid glycosides and flavonols in ginkgo biloba can clean up free radicals, protect cells in the dermis, and improve blood circulation. The effect of lowering serum cholesterol; Ginkgo has higher ornamental and economic value, and is loved by people. [0003] In my country, although ginkgo trees are suitable for growing in a wide range, they are more suitable for growing in temperate regions. Cold areas in winter will cause poor growth of ginkgo trees; ther...

Problems solved by technology

In winter, ginkgo trees are generally coated with lime and the trunks are wrapped with straw mats to keep warm and cold-proof; however, because the white coating is easy to fall off, the coating thickness is low, and the contact between the straw mats and the trunks is poor, the effect of cold protection on ginkgo trees is very low. Limited; and the traditional antifreeze method, the root protection of ginkgo trees is less, and other antifreeze measures only play a purely physical antifreeze, and do not play a role in the nutritional supplementation of ginkgo trees and the prevention of diseases and insect pests
