Grapes need a lot of nutrients, mainly nitrogen fertilizer in the early stage, and phosphorus and potassium fertilizer increase accordingly after entering the fruiting stage. In addition to organic fertilizer, nitrogen, phosphorus and potassium need 80 ~ 150 kg per hectare, which is adjusted according to variety, yield, tree potential and soil fertility. Apply base fertilizer after winter, and apply 30,000 kg of chicken and duck manure, 3,750 kg of cake fertilizer and 3,750 kg of calcium superphosphate per hectare. Topdressing before shading buds, flowering and fruit expansion, and spraying Zhuangguodiling and Gymboree microbial sweeteners in time. In the early stage, nitrogen fertilizer was mainly used to promote the growth of branches and shoots, and phosphorus and potassium fertilizer were applied in the fruit expansion stage, and the effect would be better with Gymboree microbial fertilizer. [2] Because a large number of beneficial microorganisms in microbial bacterial fertilizer proliferate and spread rapidly in the soil in geometric progression, the metabolites of functional microorganisms can improve the physical and chemical properties of the soil, improve hydrophilicity and adsorption, enhance permeability and water and fertilizer conservation ability, thus achieving the effects of grape drought and flood, increasing production and income, and improving quality. Topdressing outside the roots and spraying 0. 3% urea and 0. 2% potassium dihydrogen phosphate can promote fruit expansion and ripening. In order to produce high-quality grapes, irrigation facilities are needed in the garden to avoid drastic changes in soil dryness and wetness. Generally, there is a lot of water demand in germination stage and young fruit growth stage, so irrigation should be done in time in case of drought.
In hot areas, small sheds or T-hedges are generally used for single stems and fewer main vines. The frame is higher than the ground, which is convenient for ventilation and light transmission and reduces the damage of diseases and ground radiation to leaves and fruits. Pruning is one of the important measures to ensure the output of the year. Winter occurs after defoliation, with long branches of 8 ~ 12 knots, middle branches of 5 ~ 7 knots and short branches of 3 ~ 1 knot. Summer pruning is to remove the redundant buds in the germination stage, and coat a layer of calluses at the pruning mouth. Before flowering, too many inflorescences should be sparse, the big ones should be kept small, and the strong ones should be kept weak. When the branches and vines grow to a certain extent, they should be tied to the surface of the frame, and the tendrils should be removed in time to reduce nutrient consumption. Results 5 ~ 7 leaves were left before the inflorescence to improve the nutritional status. Grape has a high fruit setting rate, so it can be thinned appropriately to make the fruit size uniform, otherwise abnormal fruit and small fruit will appear.
