Frost damage protection solution for tree crops

Abstract

The invention provides a frost damage protection solution for tree crops. The frost damage protection solution for the tree crops is prepared from, by weight, 2-5 parts of acrylate, 5-8 parts of ammonium dihydrogen phosphate, 4-8 parts of polybutylene, 3-9 parts of lignin, 5-9 parts of salicylic acid, 2-6 parts of tea polyphenol, 2-5 parts of glacial acetic acid and 2-5 parts of cooking liquid of angelica roots, kudzu vine roots, mint and cassia twigs. The content of Cu, Fe, Mn, Zn and B ions in the frost damage protection solution is greater than or equal to 120 g / L. The frost damage protection solution is simple in proportion, convenient to use, capable of remarkably reducing the frost damage loss of trees and good in anti-freezing effect, activates biological enzymes, prevents ice nucleus bacteria from being generated, destroys the ice formation activity of freezing protein and increases heat. A freezing point value of plant cells is reduced, flowing of cellular plasm is promoted, and the cell activity is improved by 4-8 times. The water-retention and drought-resistant abilities of plants are improved, frost damage hazard is reduced, the frost damage protection solution plays the alleviating and recovering effects on the plants suffering from moderate and light degree of frost damage and is invalid to the plants suffering from severe frost damage, and the freezing point value of the plants is reduced by 5-8 degrees.

Description

Technical field: [0001] The invention relates to the technical field of tree protection, in particular to 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 spring. For tree sp...

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.
