Abstract

The invention discloses an anti-freezing disease prevention film agent for trees as well as a preparation method and the application thereof. The anti-freezing disease prevention film agent consists of main ingredients and water, wherein the main ingredients comprise the following components in part by mass: 200-1,100 parts of film-forming material, 1-100 parts of 2-methyl-isothiazolin-3-ketone, 0.033-3.3 parts of 5-chlorine-2-methyl-4-isothiazolin-3-ketone, 10-80 parts of dimethyl sulfoxide and 10-80 parts of ethylene glycol; and the film-forming material is a or b, wherein a is chitosan, and b is chitosan and carboxymethyl cellulose. The anti-freezing disease prevention film agent for trees can take a better control effect on frozen damages caused by low temperature, wind, ice nucleating bacteria and the like, is suitable for frost prevention and overwinter protection of sapling stems and branches of poplars, hybrid hazelnut trees, apple trees and other trees, as well as late spring cold prevention, cytospora chrysosperma prevention and canker prevention after blossom of apricot trees, pear trees and the like in early spring, and wound surface protection after scraping of scabs.

Description

technical field

[0001] The present invention relates to an antifreeze and disease-preventing film agent for trees and its preparation method and application, in particular to the prevention of tree stems, branches, flowers, and jelly damage, and the prevention and treatment of canker and skin rot. . Background technique

[0002] In northern my country, fast-growing poplars such as black poplars and hybrids of black poplars and green poplars have gradually replaced native poplars as the main planting species. However, in Liaoning, Jilin, Heilongjiang, Inner Mongolia, and parts of Hebei, young fast-growing poplar trees often suffer from overwintering damage such as freezing damage and die in special years, and even large trees often suffer from dry shoots and death. Similar problems also occurred in the introduction and cultivation of chestnuts, hybrid hazelnuts, apples and other fruit trees. Apricot and pear trees often suffer from flower bud freezing damage in late spring. ...
