Problems solved by technology

[0008] The invention provides a method for improving plant stress resistance and promoting flower bud differentiation. The technical problems to be solved are 1) a method for improving plant stress resistance and promoting flower bud differentiation; 2) using cellulase enzymatic hydrolysis products The quality is unstable; 3) Hydrogen peroxide is used for hydrolysis, and the hydrolyzed products are uncontrollable, which causes waste of chitosan; 4) Chitosan and magnesium need to coexist in an acidic environment, but the acidic environment is not conducive to magnesium supplementation and the effect is unsatisfactory. When the pH is higher than 6, the problem of non-coexistence of oligochitosan and magnesium

Abstract

The invention relates to a method for improving stress resistance of plants and promoting flower bud differentiation, which is characterized in that, after fruit picking in autumn, the nutrient solution containing chitosan oligosaccharide peptide magnesium is sprayed on the leaf surface, and the application can effectively improve the quality of plants. Stress resistance, promote flower bud differentiation.

Description

technical field [0001] The invention relates to a method for improving stress resistance of plants and promoting flower bud differentiation. Background technique [0002] After fruit trees are picked in autumn, in order to ensure the next year's output, fertilization is usually carried out to supplement nutrients, commonly known as "monthly fertilizer". This is because the fruits of fruit trees need to absorb a lot of nutrients from growth and development to maturity. , the nutrients in the body of the fruit tree are basically consumed, so they need to be replenished in time. [0003] At present, supplementing the nutrients of the tree body usually adopts the method of basal application of fertilizers, and the basal application of fertilizers is transported into the tree body through the root system. The root system mainly relies on the pull of transpiration to absorb nutrients. However, after autumn, the temperature drops, the transpiration of leaves decreases, and the roo...
