Painting agent for promoting grape ripening and color enhancing

Abstract

The invention relates to a painting agent for promoting grape ripening and color enhancing. The painting agent is prepared from the materials in weight percentage: 1% to 10% of ethephon, 0.001 to 0.5%of systemin, 0.1% to 2% of phytosulfokine, 0.1% to 0.5% of synergist, 15% to 25% of curing agent, 8% to 30% of thickening agent, 0.5 to 2% of wetting agent and the balance of filler. The painting agent disclosed by the invention can promote grape ripening and color enhancing through a mode of painting grape spike carpopodium, has an excellent color enhancing effect, reduces pesticide residues infruits, has no any effect on grape fruit powder and meanwhile can obviously increase yield.

Description

technical field [0001] The invention relates to a plant growth regulator, in particular to a smear agent for promoting ripening and coloring of grapes. technical background [0002] It usually takes 20-30 days for the grapes to start coloring from the berries to fully mature. At this point the berries stop enlarging and become soft and shiny. Colored varieties accumulate pigment in the cortex, and white varieties decompose a lot of green leaves, which are yellowish white and transparent, and fruit powder appears, and the seed coat gradually changes color. For the purpose of going on the market early or in batches, the conventional treatment is to use ethephon or ethephon liquid preparations when the grapes are about 60% to 70% colored, and dilute the whole plant with an aqueous solution and then spray the whole plant or soak the fruit to promote early grape coloring. 3 to 7 days to mature. [0003] With the improvement of people's living standards, people pay more and mor...

AI Technical Summary

Problems solved by technology

When using ethephon or ethephon liquid preparation, spraying the whole plant or soaking the fruit after diluting with aqueous solution, on the one hand, the time to harvest is short, and there is a certain amount of residue on the fruit surface; The impact of the fruit powder formed on the surface is also relatively large, which will cause the fruit powder to become thinner or completely absent, resulting in a decline in the quality of the grapes and a sharp drop in market purchase prices

Although the method of tree girdling can avoid the problem of pesticide residues, it will cause great damage to the tree body, and the technical difficulty is also great. Excessive girdling will cause a lot of fruit drop
