Plant antifreeze protective agent and preparation method thereof

Abstract

The invention provides a plant antifreeze protective agent and a preparation method thereof. The plant antifreeze protective agent is prepared from the following raw materials in mass ratio: glycerol:edible amino acid: sodium nitrophenolate: trehalose: methyl jasmonate: vitamin C: chlorine calcium: liquid paraffin: olive oil: monoglyceride: water is equal to (5.0-15):(2.0-8.0):(12-24):(2.0-8.0):(0.1-0.15):(0.5-2.5):(0.5-5.0):(1.0-8.0):(1.0-6.0):(0.02-0.2):(95-110). The plant antifreeze protective agent and the preparation method thereof have the advantages of enhancing the resistance of plants to external injury, enhancing the ability of the plant to resist abiotic stress, reducing the low temperature freezing injury, relieving, eliminating and healing medium and mild freezing injury plants, activating the cold induced stress reaction of the plants, promoting flowing of plant cell plasma membranes, promoting lignification of leaves, slowing down the dehydration effect of plant cell membranes, reducing the toxic effect of oxygen free radicals such as hydrogen peroxide and the like on plant cells, increasing the leaf thickness, increasing the fruit tree yield and quality and reducing the loss of leaf moisture and nutrition.

Description

technical field [0001] The invention relates to the technical field of plant antifreeze protection, and belongs to a kind of antifreeze protection ability that can significantly improve the antifreeze protection ability of woody plants, including various fruit trees and seedlings, and prevent inversion and spring cold, effectively prevent frost damage in the morning and evening, avoid / reduce The degree of frost damage. It is a plant antifreeze protectant that can quickly heal the wound site and restore the normal growth trend of the crops to mild to moderate frostbite plants.

Problems solved by technology

[0002] With the continuous growth of the global population, the contradiction between the increase of human demand for agricultural products and the limited land suitable for agricultural cultivation has become more and more prominent. , including high-altitude areas, some temperate areas began to plant subtropical plants, or transplanted temperate plants in cold winter areas; and encouraged by the policy of developing rural economy, many economic crops that were originally limited by certain climatic conditions began to expand the planting area, This can bring sustainable benefits to farmers, but it also contains huge risks, at least in crop management

Once any sudden drop in temperature occurs, especially in the case of frost, it will cause a large area of ​​crop production reduction or even failure, which will directly cause severe damage to the local agricultural ecology and industrial structure, and may even destroy the local economy, seriously dampening the enthusiasm of farmers for production.
