Clever application of foliar fertilizer into the summer can be selected according to the growth of grapes, the following foliar fertilizer, 1 superphosphate calcium leachate: Take over calcium phosphate 1 kg plus 5 kg of fresh water, dip 12 hours filtered liquid. When used, every kilogram of filtrate is diluted to 50 kg to get 2% of the leachate. 2 ash leaching of plants: Take 1 kg of plant ash to 5 kg of fresh water, dip for 24 hours and take liquid. When used, every two kilograms of the filtrate is diluted with 50 kilograms to obtain a 4% leachate. 3 Nitrogen-phosphorus mixed solution: Take 1 kg of superphosphate and 5 kg of clear water, immerse for 12 hours, remove the filtrate, and add 2 kg of urea as a stock solution in the filtrate. Use 50 kg of water per kilogram of liquid. It is also advisable to use 1 kg of fully decomposed human excreta supernatant and spray 50 kg of water. When spraying, leaf back is dominant, and branches and young fruit can also be sprayed properly. Spraying in the windless and rainy evening is best. It can also be carried out from 8am to 10am. Usually sprayed once every 10 days to 15 days, 2-4 times in a row. After re-injecting strong fruit fertilizer into the summer, it is necessary to apply topdressing once more with nitrogen fertilizer, supplemented with phosphorous and potassium fertilizers, and generally apply 20 kg of urea per mu, 15 kg of phosphate fertilizer and 10 kg of potassium fertilizer. The fertilization method can be applied deep into the ring or groove-like application method, and the soil can be filled with water after application. Strong growth potential can be applied 10 days after flower bloom or when the fruit has mung bean size, apply 500 grams of compound fertilizer to each ditch, apply water and cover soil immediately after application to prevent flowering and fruit growth, and promote fruit growth. Rapid expansion and strong shoot growth. Ten to 15 days before harvest, foliar sprays were applied with 0.2% calcium chloride or 0.2% amino acid calcium to prevent cracking. After supplementing the harvested fruit, the fertilizer grapes should be treated with nitrogen fertilizer in a timely manner to enhance the function of the leaves, extend the life span of the leaves, increase the nutrient storage of the tree, and promote the restoration of tree vigor as soon as possible. Post-harvest nitrogen supplementation has two methods of spraying and rooting. If the two are combined, the effect is better. Spray once every 10 days Spraying once 0.3% urea or 0.2% potassium dihydrogen phosphate mixture, spraying 2-3 times; Root application of 10-15 kg urea per acre soaking root is appropriate.
