There is a new method for increasing the yield of grapes

First, in combination with the previous year, on the basis of autumn basal fertilization, no fertilization before spring flowering, especially nitrogen fertilizer, in order to maintain a moderate tree vigor, but prosperous. Second, flowering does not water, do not spray, tipping spikes before flowering, smashing 1/4 to 1/5 of the whole panicle. 3. Leave 5 to 7 leaf toppings above the inflorescence before flowering. Except for leaving a bud at the top, the rest of the buds will be wiped off to allow nutrients to be fully used for fruit. Spraying pbo twice before and after flowering can increase its fruit setting rate. After physiological fruiting, leave 8 to 10 leaves topping, combined with nitrogen, phosphorus and potassium fertilization to obtain high-yield, high-quality grapes.
