The invention relates to a multifunctional
plant-derived growth improvement solution. The growth improvement solution is characterized by mainly consisting of the following components in percentage by weight: 60-70 percent of active substance extracted from natural plants and 30-40 percent of
protein hydrolyzed
amino acid in the active substance, wherein the natural plants comprise the following components in percentage by weight: 30-40 percent of
sophora alopecuroide, 15-20 percent of Chinese honeylocust fruit, 5-10 percent of
sesbania cannabina pers, 15-25 percent of rangoon creeper fruit and 5-10 percent of chinaberry
bark. The preparation method comprises the following steps of: selecting the materials,
processing and extracting the active substance; hydrolyzing
protein into
amino acid; and packaging complex trace elements. The invention has the advantages that multiple natural plants are utilized, xtracted, converted and subjected to complexing with trace elements into an aqueous agent product, thus the solution has the effects of insecticide,
acaricide and sterilization; if the solution is mixed with chemical
pesticide, about 50 percent of the dosage of the chemical
pesticide can be reduced, and the
toxicity is reduced by 4.05-11.76 times, thus the solution is beneficial to the comprehensive treatment and the ecological balance of pests in the
agriculture; if being singly used, the solution can be used for promoting crops to balancedly grow and develop, improving the resilience function and the
immunity of the crops and improving the quality, so that the
mouthfeel of fruit and vegetables is good, and the production increase is obvious.
