First, grape nutrition: Each production of 1000 kilograms of fruit (5 years old) needs to absorb nitrogen (N) 6.0 kg, phosphorus (P2O5) 3.0 kg, potassium (K2O) 7.2 kg, the absorption ratio of 1:0.5:1.2. The period of maximum N requirement for grapes is from May to September. It is the rapid growth of new shoots, flowering and flower differentiation, and the lack of nitrogen causes growth retardation, poor fruit development, and poor flower bud differentiation. The content of phosphorus in the young part of the plant is the highest. Sufficient phosphorus in the early growth stage can promote branch ripening and flower bud differentiation, increase fertilization rate and reduce fruit drop. The demand for potassium is greater throughout the entire growth period of the grape. Second, top-dressing: 1, the first time before the bud top dressing, acres of topdressing urea 5-10 kg, red day Akon series of compound fertilizer 15 kg, open small ditch applied. If no basal fertilizer is applied in the fall of last year, organic fertilizer should be applied. The fertilizer is mainly to promote new sprouting, branching, flowering and fruit setting. 2. After the second fertilizer is applied to the flower, the young fruit begins to swell. The top dressing is mainly to promote the rapid expansion of the fruit and to coordinate the growth of the foliage to reduce the fruit drop and increase the fruit setting rate. Mu is used with 15-20 kg of high-nitrogen and high-potassium compound fertilizers from the Hongkan Akon series, and then covered with water. 3, fruit coloring for the third time in the early stage, when the fruit enlargement and weight gain and new flower bud differentiation, both to consume a lot of nutrients, the need for large amounts of fertilizer, acres of red Akan series of high nitrogen and potassium fertilizer about 30 kg . Immediately after the application of fertilizer watering. This has a good effect on increasing the sugar content of fruit, increasing the color of the fruit, improving the quality of the berry, and promoting ripening. Production practices have shown that potassium application has a significant effect on yield and sugar content during the growing season of berries, and is the period of maximum potash fertilizer efficiency. Therefore, the high-nitrogen and potassium-rich compound fertilizer was applied during the first 2-3 top dressings. 4. The fourth top-dressing is carried out after fruit picking. The main effect is to quickly restore tree vigor, promote assimilation and root growth, and increase nutrient storage in the tree and root systems. Mu Shi Hong Ri Akon Compound Fertilizer 15 kg. 5, grapes are more sensitive to boron, manganese, zinc, iron deficiency. Can spray 0.1-0.2% borax solution before flowering to increase fruit setting rate. A 0.2% manganese sulfate solution was sprayed during fruit setting and fruit growth to increase berry yield and sugar content. For chlorotic iron-deficient grapes, spray 0.5-0.1% ferrous sulfate solution to cure. Zinc deficiency can spray 0.2-0.3% zinc sulfate solution. Spray 2-3 times of 0.2-0.4% potassium dihydrogen phosphate or superphosphate solution before fruit ripening.
