The invention discloses a method for improving the coloring of crop fruits, which adopts mixed liquor prepared from 70-90 parts of gamma-aminobutyric acid, 5-8 parts of monopotassium phosphate, 5-10 parts of vitamins, 2-5 parts of trace elements and a proper amount of water to treat leaves and fruits of fruit trees, the coloring effect is better than that of spraying abscisic acid, methyl jasmonate and other substances, the action effect is equivalent to that of spraying ethephon with proper concentration, but the side effect is obviously smaller than that of spraying ethephon, especially two indexes of fruit drop and storage and transportation resistance, and the coloring effect is the same as that of naturally mature fruits; the operation is simple and convenient, and the cost is low; the gamma-aminobutyric acid can be synthesized by modern biotechnology, raw materials are easy to purchase, the price is relatively low, economic burden is not caused when the gamma-aminobutyric acid is used by fruit growers, the input and output are relatively ideal, and the gamma-aminobutyric acid is simple and convenient to use and easy to master. |
