Novel plant growth regulator composition and preparation method thereof

Abstract

The invention relates to a novel plant growth regulator composition. The novel plant growth regulator composition contains the following components: 0.2-0.5 part of a brassinolide compound, 1-3 partsof 5-aminolevulinic acid salt, 300-500 parts of sodium salicylate and 500-700 parts of an auxiliary material. A preparation method of the novel plant growth regulator composition comprises the following steps: uniformly stirring sodium salicylate and the auxiliary material to obtain a mixture, dissolving the brassinolide compound into a solvent, adding octyl phenol-10, adequately and uniformly stirring to obtain a second mixture, uniformly spraying the second mixture to the mixture, airing, and crushing, so as to obtain powder. According to the novel plant growth regulator composition, the growth and dormancy of crops can be broken through, the seed germination can be promoted, the survival rate of plants can be increased, the differentiation of adventive roots of calluses can be induced;the allocation of nutrients is adjusted, the sugar content of fruits is increased, and the disease resistance and stress resistance are improved; and the plant photosynthesis is improved. The preparation method has the advantages of simplicity, convenience in use, low cost and no pollution.

[0002] At present, there are different degrees of damage to plant production in the environment of low temperature and freezing in winter, high temperature and high humidity in summer, or insufficient light, resulting in damage to leaves, roots, growth points, flowers, fruits, dead seedlings, falling flowers and fruits, etc. , resulting in low crop survival rate, poor resistance to stress and disease, and decline in yield and quality. In order to avoid the above situation and ensure the normal growth of plants, it is common to use different plant growth regulators on crops. , plant growth regulators are exogenous non-nutritive chemical substances, which can usually be transmitted to the site of action in plants, and can promote or inhibit certain aspects of their life processes at very low concentrations. Plant growth regulators have many uses : Promote rooting, promote cell growth and division, control germination, lateral buds or tillers, induce seedless fruit; control fruit drop; control fruit shape or maturity; enhance stress resistance, such as disease resistance, drought resistance, salt resistance, cold resistance etc.; however, there are many types of plant growth regulators, with different physical and chemical properties and action characteristics, and can only produce specific effects on target plants under specific application conditions. The effect of growth, or even the opposite result, leading to adverse results such as phytotoxicity
