Grape management technology: how to prevent grape fruit cracking?

Now grapes can be put on the market, but grape fruit cracking is serious, how to prevent grape fruit cracking? Learn to ask friends to help introduce the prevention and control of grape cracking fruit planting network summed up a few points, the following to do a detailed introduction for your reference. 1. Due to the large number of Rain Water this year, during the fruit coloring period, the fruit produced a lot of swelling and pressure by absorbing water from the fruit surface and roots, resulting in different degrees of fruit cracking of many grapes. Ploughing and loosening the soil in time after rain to reduce the fluctuation of soil moisture can effectively prevent the fruit cracking at the top of the grape. 2. Clayey soil is easy to harden, waterlogging and drought, resulting in fruit cracking during grape growth and covering with plastic film. When Rain Water is too much, it can prevent the root system from absorbing too much water and reduce the change of soil moisture. When drought, the combination of plastic film mulching and irrigation can effectively prevent grape fruit cracking. 3. Unreasonable pruning, leaving too many old leaves and too few new leaves, resulting in a decrease in the ability to regulate water, easy to crack fruit in the event of rain, change the traditional coring method, leave more leaves, reach more than 25-26 normal leaves per fruit branch, and enhance the function of the tree to regulate water. 4. The tree body is weak and too much fruit is left, resulting in unreasonable tree load and serious fruit cracking. By thinning branches and ears and adjusting the load, the strong branches leave 2 ears of fruit, the middle branches leave 1 ear of fruit, the weak branches do not leave the ear, remove the accessory ear and pinch the ear tip in time, so that the size of the ear is moderate. 5. Irrational application of inorganic fertilizer, less organic fertilizer, easy to crack fruit, apply appropriate amount of nitrogen fertilizer, increase phosphorus fertilizer, potassium fertilizer and other trace fertilizer, and apply more organic fertilizer. 6, pathological cracking fruit, most fruit trees or heavy or light occurrence of powdery mildew, white rot and other diseases, resulting in grape pathological cracking, mainly manifested as cracked pericarp, shallow cracks, no pulp outflow, prevention and control of powdery mildew, 2000 times solution of 15% trimethoprim, 800 times of carbendazim wettable powder that can be sprayed, or 1000 times of methyl topiramate.
