Amino acid biological preparation for improving crop stress resistance

Abstract

The invention relates to an amino acid biological preparation for improving crop stress resistance. The amino acid biological preparation comprises the following components in parts by weight: 5-12 parts of a microbial preparation, 15-30 parts of paper mulberry powder, 15-25 parts of suaeda salsa powder, 30-70 parts of soybean meal powder and 15-25 parts of bagasse. The microbial preparation is prepared by mixing the following components: bacillus amyloliquefaciens, nitrogen-fixing bacteria, saccharomycetes, bacillus natto and bacillus laterosporus according to the volume ratio of 6-15: 2-4: 25: 2-5: 3-5: 3-7, and the viable count of each bacterium is not less than 109 per gram. Various materials are used for providing a large amount of amino acids for crops, a water-retaining, fertilizer-retaining and healthy growth environment is created for the growth of the crops, and the stress resistance of the crops is improved.

Description

technical field

[0001] The invention relates to a biological agent, especially an amino acid biological agent for improving stress resistance of crops. Background technique

[0002] my country is a large agricultural country. Although it has a vast territory, there is not much arable land, and there are many barren lands. Some soils are short of fertilizer and water. In order to pursue crop yields, people will use large amounts of chemical fertilizers for a long time to maintain the growth and development of crops. The formation of yield has caused the continuous decline of the stress resistance of crops, seriously damaged various nutrients in the soil, the concentration of acidic and toxic substances in the soil has risen sharply, and the soil is generally acidified and hardened, resulting in a significant decline in the quality of agricultural products and even damage to the root system of crops. Even if a large amount of fertilizer is put in, it is difficult to be absorbed ...
