Five points for management after grape picking

Inhibiting the growth of branches and vines will consume a large amount of nutrients in the tree body. Measures such as topping and erasing the secondary shoots should be taken to control its growth in order to reduce the ineffective consumption of nutrients and promote the main vine and the retained secondary shoots to be strong and the buds full and full . You can also spray 0.05% Bijiu solution to inhibit prosperous growth. At the same time, the branches and vines should be pruned reasonably. The thick branches should be kept more, and the thin branches should be kept less. Excessively dense branches, thin branches, and diseased branches should be thinned out as soon as possible.

The orchard is prone to overgrown weeds in summer and autumn to prevent waterlogging and drought. Deep ploughing and loosening the soil should be carried out between September and October, when the cut root system can heal quickly. This soil tillage is often combined with basal fertilizer. Generally, the tillage depth is about 20 cm, shallower near the tree trunk and deeper outward. In case of drought in autumn or winter, irrigate in time to keep the field water holding capacity not less than 60% to facilitate soil moisture.

Reduce damage in some places. After the grapes are harvested, a large number of auxiliary shoots and old leaves are cut off, which not only affects the maturity of the branches in the year, but also tends to force winter buds, which will seriously affect the growth and results of the plants in the next year. Generally, leaves are not picked and fewer shoots are removed after harvest. Keep strong foliage. At the same time, prevent mechanical damage to branches and leaves during field operations, and ensure that branches and vines mature normally.

Arrange the orchard due to frequent operations such as picking and management, and the soil is easy to be solidified. After picking the fruit, you should immediately carry out a row of soil loosening to increase the looseness and air permeability of the soil and promote new roots. Also combine autumn and winter pruning to organize the orchard better.

Prevent and eliminate diseases Grape leaves are susceptible to downy mildew, powdery mildew, white rot, brown spot and other diseases. After the grape fruit is picked, it can be sprayed alternately with 80% spray of 500 times liquid of wettable powder and 78% of Kobo wettable powder 500 times of liquid, spraying once every 10 days.
