Prevent grape cracking from picking fruit

Grape cracking seriously reduces its commercial and economic benefits. The reasons for the occurrence of cracking include: long-term drought after the rain and large irrigation water, uneven water supply, young fruit during the case of windy, hot weather, pruning, fruit rinsing irrational, overload and disease caused by. The main reasons for cracking fruit should be taken from the following aspects: During the fruit growth and development period, the water supply should be kept even. In order to prevent hot seasons, soil moisture imbalance caused by cracking, pay attention to timely irrigation, and drainage after the rain, in order to reduce the soil wet and dry difference and the breeding of diseases after the rain. During the later period of fruit development, a few times, a small amount of water, to prevent flooding irrigation, to avoid drastic changes in water content. The fruit trees are regularly sprayed with “new high-fat film” to moisturize and protect their skin, prevent disease, prevent disease, resist sun exposure and prevent burns, and can also reduce the risk of decompression, light and long-lasting drought, and rainy windy winds to bring about adverse effects on fruit trees and help restore the vitality of growth. . For varieties with tight fruit, the results should be changed before the flower shoots to take heart after flowering, make it appropriate to drop fruit, or sparsely remove some spikelets before flowering, in order to loose and moderate the ear. Through the thinning, sparse adjustment of load. To prevent too tight fruit, squeezed and even lead to cracking. In order to prevent excessive branching and excessive nutrient consumption and affect the supply of nutrients needed for fruit development, excessive legumes, dense branches and diseased fruit branches should be removed to reduce nutrient consumption. For the pruning of wounds should be promptly painted "coating anti-corrosion film" to prevent wound infection bacteria, protect wound healing and reduce the occurrence of pests and diseases. Spraying the plant growth regulator “Melon and Zhuang Ti Ling” before flowering, young fruit stage and fruit expanding stage, regulating the growth function of the tree into the reproductive function, increasing the supply of physiological nutrient requirements, and increasing the speed of fruit enlargement. Flowers and fruits, enhance color, safe and no side effects.

Sodium Hyaluronate, which is a polymer polysaccharide of biological materials formed by N-acetyl glucosamine and glucuronic acid through iterative connected, has a high degree of viscoelasticity, plasticity, permeability and good biocompatibility. This product is manufactured with the raw material of comb based on the process of fine biochemical technology, separation, purification, and refining. The gel contains 1% HMW of sodium hyaluronate and physiological buffer. This product, which is a colorless, odorless, sterile, pyrogen-free transparent viscous liquid, adopts the aseptic processing technology to filter sterilization.
