Management essentials before and after grapes budding

Water and fertilizer management. During the budding period of grapes, a series of physiological activities such as budding, branching, leaf spreading, and flowering are required, and sufficient water and nutrients are required. The germination water depends on the moisture condition of the garden soil. Sandy soil or sandy loam vineyards must be thoroughly irrigated with germination water, and other soil gardens can be less irrigated. Fertilizer for accelerating germination should be applied 1-2 weeks before the germination of the grapes, with urea applied in strips, and silicon, calcium, potassium, and magnesium fertilizers should be added at the same time, if the soil is compacted, then other effective fertilizers should be added.

Use Chuawang 3 at the right time, spray Chuawang 3 before germination to promote flower bud differentiation, assimilation induction promotes the transmembrane signal conversion of plant cells, forcing the apical shoots to replenish a large amount of nutrients, and the inertial advantage of rushing shoots is quickly weakened to a capping state.

Do a good job in disease prevention and control, in order to reduce the number of pests and diseases in the garden, before the buds swell and appear pompoms but no green, the whole garden should be thoroughly sprayed with a tree-protecting general. When the young leaves of the grapes are first exposed, a new high-lipid film can be used for spraying. The leaves play a role in preventing germs; the grapes grow to the 2-3 leaf stage and spray pesticides to prevent Lygus lucorum.

Pruning, removing sprouts, wiping and fixing the buds. After the grapes are on the shelves, the work of wiping the buds should be carried out. The time for wiping off the buds is determined according to the tree vigor. As a result, if the branch thickness is between 0.6-1 cm, the buds should be wiped early, and weak buds should be wiped to leave strong buds; if the results are more than 1 cm, the buds should be wiped late, and strong buds should be wiped to leave weak buds when new shoots grow to about 10 cm. In the case of not very dry, no watering and no fertilization, reduce the tree vigor and consume nutrients to increase the fruit setting rate and reduce the occurrence of large and small grains.
