Grape leaf surface spray fertilizer, less investment, quick effect, easy operation, and fertilizer saving, is a good measure to develop grape production and increase production and income.
The best time for grape leaf spray is in the pre-growth, pre-flower, post-flower and post-growth stages. In the early stage of growth, nitrogen fertilizer should be used as the main method, spraying 0.3~0.5% urea and 0.2-0.3% potassium dihydrogen phosphate solution, which can increase and thicken the leaves, enhance the photosynthesis of the leaves, and promote the accelerated growth of new shoots. Before flowering, it is usually carried out about 10 days before flowering. At this time, it can be sprayed with a solution of 0.2-0.3% borax or zinc sulfate to improve the fruit setting rate and prevent deficiency. Spraying fertilizer after flowering, generally spraying after the flowering period of young fruit, with 0.2-0.3% urea and 0.3% potassium dihydrogen phosphate solution, can accelerate the rapid expansion of young fruit and increase the yield. After growth, it should be based on phosphorus and potassium fertilizer. It can be sprayed with 0.5-1% potassium dihydrogen phosphate solution to improve fruit quality and increase sugar content. At this time, it can also be combined with spraying a fungicide such as zinc, aluminum phosphate, etc., and the curative effect on the grape disease is also remarkable, and it can be achieved in one fell swoop. Grape leaf surface spray fertilizer, before 10 o'clock in the morning and in the evening, the effect is good, in the high temperature and dry sunny days, the spray fertilizer concentration should be thinner, raining within 8 hours after the spray fertilizer, after the rain, the weather can be sprayed once.
