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 tree crop frost damage protection solution

Abstract

The invention provides an application method of a tree crop cold damage protection liquid. The application method comprises the following application steps: A before plant dormancy in the late fall, adding water to dilute the tree crop cold damage protection liquid into 800fold liquid in volume for spraying; B 3-7 days before frost or cold wave, adding water to dilute the tree crop cold damage protection liquid into 600fold liquid in volume for a root-irrigation operation; (C) before and after transplanting a plant, adding water to dilute the tree crop cold damage protection liquid into 1000fold liquid in volume for the root-irrigation operation; and (D) before winter, adding water to dilute the tree crop cold damage protection liquid into 50-80fold liquid for trunk and twig brushing operations, wherein the steps are requested to be operated between 3 DEG C and 8 DEG C. The tree crop cold damage protection liquid comprises the following components: acrylate, ammonium dihydrogen phosphate, polybutylene, lignin, salicylic acid, tea polyphenol, glacial acetic acid, radix angelicae, puerarin, mint and cassia twig. The application method is simple to proportion, convenient to use and good in anti-freezing effect; and the cold damage loss of the trees can be greatly reduced.

Description

Technical field: [0001] The invention relates to the technical field of forest protection, in particular to a method for using a woody crop freezing damage protection solution. Background technique: [0002] In the traditional prevention and control of tree frost damage, lime and lime sulfur are used to whiten the branches and trunks, which can reduce the damage to the sunny skin due to the large temperature difference between day and night, and can kill some overwintering pests and diseases. The whitening time is generally between late October and mid-November, and the whitening time cannot be delayed. If the temperature is too low, the whitening material will fall off in flakes. After the trunk is painted white, the absorption of solar heat by the tree body in early spring is reduced, the speed of tree temperature rise is reduced, and the germination of the tree body can be delayed by 2-3 days, thereby effectively preventing the tree body from encountering frost in early...
