Using method of spraying liquid protecting tree trunks against frost cracking

Abstract

The invention provides a using method of spraying liquid protecting tree trunks against frost cracking. The using method includes the following using steps that A, in the late autumn, before plant dormancy, 800 volume fold of water is added into the spraying liquid protecting tree trunks against frost cracking so that the spraying liquid can be diluted, and diluted liquid is sprayed; B, 3-7 days before frost or cold-air outbreak, 600 volume fold of water is added into the spraying liquid protecting tree trunks against frost cracking so that the spraying liquid can be diluted, and root irrigation operation is performed through diluted liquid; C, before and after plant transplantation, 1050 volume fold of water is added into the spraying liquid protecting tree trunks against frost cracking so that the spraying liquid can be diluted, and root irrigation operation is performed through diluted liquid; D, before winter, 50-80 volume fold of water is added into the spraying liquid protecting tree trunks against frost cracking so that the spraying liquid can be diluted, and diluted liquid is sprayed to tree trunks and branches. It is required that the steps are operated at the temperature of 3-8 DEG C. The spraying liquid protecting tree trunks against frost cracking is composed of ethylene glycol, methyl ester, isobutylene, potassium humate, calcium chloride, tea polyphenol, citric acid, igusticum, folium isatidis, allium fistulosum and cinnamon. The spraying liquid is simple in matching, convenient to use, capable of substantially reducing freezing damage losses of trees and good in anti-freezing effect.

Description

Technical field: [0001] The invention relates to the technical field of forest protection, in particular to a method for using spraying liquid for preventing the freezing and cracking of tree trunks. Background technique: [0002] In northern China, the severe cold, dry and windy winter will cause some less hardy tree species to suffer frost damage or cause "physiological drought" (also called freezing drought, cold drought or winter drought) from winter to early spring, causing local branches to wither. From the damage to some branches, the whole plant will die. In order for trees to survive the winter safely, it is necessary to understand the causes of low temperature hazards and take necessary measures. For example, root frost damage is due to the lack of natural dormancy in the root system and poor frost resistance. Roots close to the ground are vulnerable to freezing damage, especially in sandy land with little snow and arid areas in winter. The root system is frozen and...

Problems solved by technology

However, this method is not suitable for colder areas. In colder areas, most of them use tree trunks to wrap straw curtains, and then wrap plastic cloth outside the straw curtains to prevent freezing.

The operation is cumbersome, the labor intensity is high, and it needs to be disassembled again next spring, resulting in a serious waste of resources. In view of this technical problem, it is necessary to have a simple proportioning, easy to use, which can greatly reduce the loss of tree frost damage and antifreeze effect. A good method of using a spray liquid to prevent tree trunks from freezing and cracking
