Grape spraying foliar fertilizer, fertilizer efficiency, labor saving, good sweetening effect, high yield, has been widely used in production. Generally, spraying urea and boron fertilizer mixture at the flowering stage can increase the fruit setting rate; spraying the superphosphate solution with the young fruit and the berry ripening period can significantly increase the sugar content of the fruit and enhance the disease resistance; Potassium fertilizer, yield increased by 10% to 15%, sugar content increased by 1.5% to 2.5%; berry softening period sprayed rare earth solution, increased yield and sweetened. Grape leaf fertilizer can be sprayed throughout the growth period. It is best to spray the tip fertilizer before the growth of the new shoots, promote early fast-growing, set up a high-yield seedling rack; spray stable flowers and fruit fertilizer during flowering and fruit setting; When the fruit is inflated, it is sprayed with strong fruit fertilizer; if the grape has symptoms of deficiency during the growth period, it is better to apply fertilizer control. Fertilization variety The variety of fertilizers needs to be emphasized because of the different growth stages of the grapes. Before and after germination, leaf-to-flowering, spraying with nitrogen fertilizer, with some phosphate fertilizer; adding boron fertilizer during flowering; spraying the phosphorus and potassium fertilizer during the expansion period of the berries; spraying the rare earth in the early stage of softening of the berries. Commonly used fertilizer and spraying concentration: 0.2%~0.4% urea solution, 0.3%~0.5% ammonium sulfate solution, 2%~3% superphosphate leaching solution, 0.4%~0.5% potassium sulfate solution, 1% potassium nitrate solution, 3 % grass ash leaching solution, 0.2%~0.3% potassium dihydrogen phosphate solution, 0.1%~0.2% borax or boric acid solution, 0.05%~0.15% zinc sulphate solution, 0.1% manganese sulphate solution, 0.1% magnesium sulphate solution, 0.1% sulphate Iron solution, 0.05%~0.1% rare earth nitrate solution, 0.1% rare earth animal and plant treasure solution. Spray method The young leaves of the grapes have stronger ability to absorb fertilizer than the old leaves, and there are many stomata on the back of the leaves, and the fertilizer is absorbed quickly. Therefore, the foliar fertilizer spraying site should be based on the young shoots, young leaves and the back of the leaves, and strive to make the droplets fine, evenly spread the foliage, until the leaves are all wet, and the fertilizer is dripping. It is usually sprayed 4 to 6 times throughout the growth period. It can be sprayed with various fertilizers as needed, or it can be mixed with pesticides and plant growth regulators.
