Fruit coloring adjunct and method for promoting fruit coloring with same

Abstract

The invention discloses a fruit coloring adjunct and a method for promoting fruit coloring with the same, wherein the fruit coloring adjunct comprises anthocyanosides liquid, also can comprise at least one of photosynthetic bacteria, chitin, chitosan, chitosan oligosaccharide, monopotassium phosphate, lemery and wetting agent. Within one to forty-five days before picking up, the fruit coloring adjunct is sprayed to the surface of fruit once to five times. The effect of directly spraying the fruit coloring adjunct to the fruit is better than the effect of spraying the fruit coloring adjunct toleaf surfaces. No harmful substance remains in the fruit by using the method, and the sugar content and the hardness of the fruit are enhanced. The invention is suitable for fruit, such as apples, grapes, cherries, tomatoes, and the like, and has important meanings for enhancing the fruit valve, increasing the export yield, and enhancing the income of peasants.

Description

Technical field: [0001] The invention relates to a fruit color enhancer and a method for using the fruit color enhancer to promote fruit coloring, which belongs to the application of biochemical reagents in agricultural production and is specially used for promoting plant fruit coloration. Background technique: [0002] The appearance color of fruit is an important quality index of many colored fruits such as apples, pears, peaches, grapes, etc., and it is also an important manifestation of the commercial quality of the fruits. The reason why my country's fruit export quantity is small and the export price is low is that the fruit appearance quality is not high. The area of ​​fruit trees in my country has grown steadily at an average annual rate of about 9%. Since 1994, my country's fruit tree cultivation area and total quantity have ranked first in the world. In 2003, my country's fruit tree production area reached 9.4367 million hm, accounting for 18% of the world's fruit...
