Post-harvest fertilizer is usually sprayed once every 10 days with urea and potassium dihydrogen phosphate mixture, continuous spraying 2-3 times. At the same time, combined with photosynthetic nutrient film fertilizer can effectively improve the photosynthetic efficiency of leaves, restore tree vigor and increase tree nutrients. If there are few results in the current year, partial fast-acting nitrogen fertilizers, such as decomposed human excreta, pig manure, urea, etc., may be added under weak tree vigor. Basal fertilizer is the most important part of fertilizing vineyards in red vineyards. It is better to use basal fertilization in autumn as soon as possible. Basal fertilizer, circulatory fertilizer, compost, and other organic fertilizers plus calcium superphosphate are used for basal fertilizers. In order to reduce the nutrient's ineffective consumption, the vines will be consumed by a large amount of nutrients in the tree branches, which will consume a large amount of nutrients in the trees. This will promote the growth of the main vines and the retained secondary shoots. Full and full. It can also be used to promote the prosperous control of Kaowang No. 3, blocking the upward flow of the catheter. Disease prevention and disease removal Red grape leaves are susceptible to disease infection, so red grape extract can be selected after spraying fruit trees with new high fat film to prevent infection and replication of pathogens and improve the plant's own resistance. Clearing the orchard Because of the frequent operation of harvested grapes, the soil is easy to be practical, so after the fruit is harvested, a cultivator ripping should be performed to increase the loose air permeability of the soil and promote new roots. At the same time, combined with autumn and winter pruning, the branches and leaves of dead branches and leaves in the orchard are completely cleared out of the field for destruction, so as to reduce the damage of pests and diseases in the following year.
