Problems solved by technology

In the 1930s, it was suggested that spraying thiocyanate could promote fruit coloration, but it was later found that improper spraying of thiocyanate could cause serious leaf damage.
Thiosulfates can brighten citrus, but the effect is not particularly satisfactory
In the 1960s, it was proposed that B9 can promote the accumulation of anthocyanins in apples, and 6-BA, abscisic acid, GA3, and uniconazole can promote fruit coloring. However, people’s attention to food safety issues in recent years has made this type of plant growth regulator has been used with great care
So far, although many researchers have done a lot of experiments, there are very few plant growth regulators that have been put into use, or the coloring effect is not obvious, or it is not easy to cause some side effects

Embodiment 1

[0066] Embodiment 1: adopt anthocyanin liquid as fruit color enhancer, dilute anthocyanin liquid 100 times and spray leaf surface four times within one month before apple picking bag. The above anthocyanin solution is prepared by soaking grape skins with alcohol and 0.5% dilute acid for 20-30 hours.

Embodiment 2

[0067] Embodiment 2: The solution prepared by mixing photosynthetic bacteria and anthocyanin solution is used as a fruit color enhancer, the weight ratio of photosynthetic bacteria and anthocyanin solution is 1:99, and the solution prepared by mixing photosynthetic bacteria and anthocyanin solution is diluted 200 times, spray the fruit surface 10 days before grape picking. The above anthocyanin solution is prepared by soaking purple cabbage with alcohol and 0.5% dilute acid for 20-30 hours.

Embodiment 3

[0068] Embodiment 3: adopt the solution that anthocyanin liquid, chitin, chitosan, potassium dihydrogen phosphate and wetting agent are mixed and prepared as fruit color enhancer, anthocyanin liquid, chitin, chitosan, potassium dihydrogen phosphate The weight ratio of the wetting agent and the wetting agent is 100:5:5:1:0.5, and the solution prepared by mixing the anthocyanin solution, chitin, chitosan, potassium dihydrogen phosphate and the wetting agent is diluted 150 times. Spray the surface of the fruit once within the first 5 days. The above-mentioned anthocyanin solution adopts red wine.

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...
