Second, heavily apply fruit-setting fertilizer. Fertilize 10 days after the flowers fade or when the fruit is the size of a mung bean. Dig a trench around each plant and apply 500 grams of compound mixed fertilizer, then water promptly and cover with soil. Then spray Guaguo Zhuangdiling on the leaves. This is a key fertilizer application to promote young fruit enlargement and branch and shoot growth. It must be sprayed on time, which can effectively improve the fruit's enlarging vitality and achieve the effect of increasing yield.
Third, after grape harvest, nitrogen fertilizer should be supplemented promptly to enhance leaf function, extend leaf lifespan, and increase nutrient storage in the tree. Post-harvest nitrogen supplementation has two methods: spraying and root application. If the two are combined, the effect is even better. For spraying, use a 0.4% urea solution; for root application, it is appropriate to use 4 kg of urea per mu.
