Biological stimulant containing plant immunocompetent protein and 5-aminolevulinic acid or derivative thereof

Abstract

The invention provides a biological stimulant containing plant immunocompetence protein and 5-aminolevulinic acid or a derivative thereof, the biological stimulant comprises two effective components, namely the plant immunocompetence protein and the 5-aminolevulinic acid or the derivative thereof, and the weight ratio of the plant immunocompetence protein to the 5-aminolevulinic acid is (0.05-15): 1. The plant immunocompetence protein and the 5-aminolevulinic acid or the derivative thereof in the biological stimulant have a mutual synergistic effect, so that the biological stimulant has obvious effects of increasing the yield of crops, improving the disease resistance of the crops, improving the quality of the crops and the like. Specifically, 1, the two components can synergistically improve the immunity and disease resistance of crops; 2, the action mechanisms of the two active components are different, and the two active components can significantly and synergistically improve the crop yield and crop quality.

Description

technical field [0001] The invention belongs to the field of bio-agriculture, in particular to a biostimulant composition for promoting the synergistic growth and yield of crops, in particular to a biostimulant composition comprising plant immune active protein and 5-aminolevulinic acid or its derivatives Biostimulant composition. Background technique [0002] Plant immune active protein is mainly a general term for a pathogenic protein elicitor extracted from screened fungal or bacterial proteins. It is a natural protein derived from fungal microorganisms. A kind of magical special extracellular signal outside the cell, which can efficiently stimulate the overall immune system of the plant and the rapid growth system of the plant through the signal transduction of the plant receptor (mainly the cell membrane receptor of the plant leaf), so that the plant can quickly develop disease resistance , Drought resistance and frost resistance and other stress resistance protection ...

AI Technical Summary

Problems solved by technology

[0004] At present, in the process of planting agricultural crops, due to the long-term unreasonable use of fertilizers and pesticides, such as the application of high-nitrogen, high-phosphorus and other chemicals to regulate crop growth, increase crop yield, and long-term application of chemical phosphorus-containing pesticides, the existing in the soil Excessive concentration of a single nutrient will not only cause an excessive stock of physical phase reactions in the soil, but also produce harmful substances in the soil, and become the main factor causing soil compaction in some areas, resulting in a decrease in crop yield and a decrease in the quality of agricultural products, which violates the soil ecology. The natural development law of the environment, therefore, creating new biological fertilizers, rationally applying fertilizers, improving the comprehensive utilization efficiency of fertilizers, and activating soil life are important means for the fertilizer industry to achieve sustainable development
