Grapes are perennial plants. They grow up every year and need to absorb a lot of nutrients from the soil. In order to maintain continuous healthy growth and continuously improve production and quality, they must be fertilized reasonably. It was determined, per 100 kilograms of berries purity nitrogen to be absorbed 0.56 to 0.62 kg, 0.68 to 0.72 kg phosphorus, potassium, 0.56 to 0.62 kg. Therefore, it is very important to balance the rational fertilization. Fertilization of grapes can be divided into basic application and follow-up. 　　 1. Base fertilizer: Generally , it is best after 9 to 10 months after fruit harvesting . This store nutrition, enhance tree vigor, high yield laying the foundation for the following year. It can be used for wintering in the northern winter. Some fall no longer applied, and this is more demanding for fertilization in the spring. The fertilizer must be fully decomposed. Generally manure, manure, chicken, pig, cow dung and other increased over the use of calcium phosphate. The amount is generally determined load and age: Usually acre of land applied manure 3,000 to 5,000 kg 30 - 50 kg of superphosphate and new biological fertilizer soil Sidel 4 to 8 kg. Note: The method of decomposing: 1. Add 500 ml of bacon biological bacteria to each manure and keep it for 7 to 15 days. 2. Each square in manure cornmeal added 2 kg, 1 kg of brown sugar, 1 kg of urea, 5 kg of wheat bran water. Mix well in the case of semi-dry, stuffy insulation stack 7 to 15 days, most good stack with superphosphate and stuffy after treatment with organic fertilizer, the fertilizer can greatly improve the efficiency. 　　 2, top dressing: fertilizer according to the characteristics required of grapes, according to the different stages of growth is essential to improve dressing, generally throughout the growing season fertilizer two to four times. Suggestion: Before the first germination, the nitrogen and phosphorus fertilizers are mainly used with a small amount of potassium fertilizer; the second berry phase is mainly composed of phosphorus and potassium fertilizers, and the appropriate amount of nitrogen fertilizer; in the third coloring period, the phosphorus and potassium fertilizers are mainly applied with a small amount of nitrogen. fat. (Note: When dressing, in order to improve the utilization of fertilizers and improved soil fertility fertility must add the right amount of humic acid products such as: dynamic ninety-nine 0.5 to 1 kg / acre, such as fertilizer and hybrid vigor can ninety-nine dissolve one day in advance After that, the next day, the effect is better with water.) 　　 3 , root fertilization (foliar fertilizer): in the grape growth process, foliar fertilization can get twice the result with half the effort , not only greatly improve the fruit set rate, improve fruit quality and prevent the occurrence of physiological deficiency. A , the flowering period of 0.05% ~ 0.1% boron fertilizer + Haitian force 600 times can increase the fruit set rate. B. Spraying calcium fertilizer before flowering, young fruit, and berry can increase yield and quality and prevent cracking. Such as: 1 calcium nitrate + Haitian force 600 times liquid. 2 amino acid calcium. 3 superphosphate lime leachate 1% ~ 3% + Haitian force 600 times. During the fruit setting period, spraying 0.02% potassium dihydrogen phosphate or 3% grass ash leaching solution ( soaking one day before spraying ) can greatly increase the sugar content and yield.
