A kind of environment-friendly antifreeze agent for fruit trees and preparation method thereof

Abstract

The invention belongs to the technical field of antifreezing agents for fruit trees and specifically relates to an environment-friendly antifreezing agent for the fruit trees and a preparation methodof the antifreezing agent. The invention provides the environment-friendly antifreezing agent for the fruit trees and the preparation method thereof, aiming to overcome defects in the prior art. According to the preparation method, algal polysaccharides and plant-sourced small-molecule polypeptide are prepared into a nano-like lipidosome solution, prohexadione calcium is prepared into nano microcapsule dispersion liquid, and he environment-friendly anti-freezing agent for the fruit trees is formed through the nano-like lipidosome solution, the nano microcapsule dispersion liquid, glycerinum, vitamin E, sodium alginate, 50 wt% aqueous polyethyleneimine (PEI) solution and mannitol. The prepared antifreezing agent can achieve quick-acting and long-acting antifreezing effects, is applicable tomultiple economic crops, such as apple trees, tea, mulberries, strawberries, grapes and various flower and fruit seedlings, and has the antifreezing effect especially for flower buds, sprouts and leaves of the apple trees and the like.

Description

Technical field

[0001] The invention belongs to the technical field of antifreeze agents for fruit trees, and specifically relates to an environment-friendly antifreeze agent for fruit trees and a preparation method thereof. Background technique

[0002] North my country often encounters erratic temperature changes in the early spring, late autumn and early winter. Crops often suffer severe freezing damage due to sudden changes in weather and sharp drops in temperature, resulting in damage to the leaves and flowers of cash crops such as fruits and vegetables. At present, in agricultural production practice, in order to prevent plants from freezing damage, smoking or mulching is often used, but the smoking method produces a large amount of carbon monoxide and carbon dioxide, and the effect is very small; the mulching method is to cover crops such as hay, straw, and wheat straw. It has limitations and is limited to small-scale pastoral areas, and the cover needs to be removed later...
