Biostimulant for coloring and preparation method thereof

Abstract

The invention relates to a biostimulant for coloring and a preparation method thereof. The biostimulant for coloring is characterized in that it contains production-increasing amine, propyl dihydrojasmonate, auxin and a solvent. The application can promote coloring and improve crop quality.

Description

technical field [0001] The invention relates to a biostimulant applied to coloring and a preparation method thereof. Background technique [0002] Propyl dihydrojasmonate (PDJ) is a derivative of the plant endogenous hormone jasmonic acid, and the plant endogenous hormone jasmonic acid, as a plant endogenous death substance, can release a signal that promotes the synthesis of plant endogenous ethylene, thereby promoting the plant endogenous ethylene synthesis. Synthesis, ethylene, as an essential precursor for plant fruit coloring, can promote fruit coloring. The effect of propyl dihydrojasmonate is similar to that of plant endogenous jasmonic acid, which can promote the generation of ethylene, leaf aging, leaf shedding, and stomatal closure. When applied to fruit coloring, it can achieve the effect of coloring in advance. Compared with the normal coloring fruit, there are problems of short growth period and insufficient fruit organic matter reserve, which affects the qualit...

[0002] Propyl dihydrojasmonate (PDJ) is a derivative of the plant endogenous hormone jasmonic acid, and the plant endogenous hormone jasmonic acid, as a plant endogenous death substance, can release a signal that promotes the synthesis of plant endogenous ethylene, thereby promoting the plant endogenous ethylene synthesis. Synthesis, ethylene, as an essential precursor for plant fruit coloring, can promote fruit coloring. The effect of propyl dihydrojasmonate is similar to that of plant endogenous jasmonic acid, which can promote the generation of ethylene, leaf aging, leaf shedding, and stomatal closure. Applied to fruit coloring, it can achieve the effect of coloring in advance. Compared with the normal coloring fruit, there are problems of short growth period and insufficient fruit organic matter reserve, which affects the quality of the fruit.

[0004] However, although propyl dihydrojasmonate and production-increasing amine can be used to better color and prevent the effect of crop quality reduction, they cannot improve the quality of the fruit well.

At the same time, although the use of propyl dihydrojasmonate and production-increasing amine can promote coloring, there are problems of causing premature senescence of plants and reducing yield

[0005] At the same time, a solution or emulsion is prepared by mixing propyl dihydrojasmonate (PDJ), production-increasing amine (DCPTA) and auxin. After a certain period of storage, the color of the product will change from colorless or light yellow to brown or black. , the product was introduced to the market, and consumers reported that the use of colorless or light yellow biostimulants for coloring has a good effect on increasing yield and improving crop quality, but the use of brown or black biostimulants has no obvious effect, and even Ineffective, which creates trouble for product promotion
