After the harvest of the grape
Timely Clear Garden
Weeds are removed from the garden, and the litter of the orchard and the pruned branches and leaves, as well as diseased fruits, diseased ears, diseased leaves, and diseased branches that are discarded in the garden after fruit picking are collected and buried deep outside the park or burned to eliminate Insect source.
Timely trim
The autumn cuts continue to carry out toppings, forks, remove tendrils, wipe off secondary shoots and thin branches, and remove severely damaged leaves to reduce nutrient consumption, regulate the nutrient flow of the tree, and promote full maturity of buds. Improve ventilation and light transmission conditions to benefit the results of the coming year.
Timely spraying of post-harvest fertilizer
After the grapes are harvested, they must be sprayed with foliar fertilizer in time to restore the tree vigor and enhance the photosynthetic capacity of the leaves. A mixture of 0.2% urea, 0.1% magnesium sulfate and 0.2% potassium dihydrogen phosphate is sprayed once every 10 days. Spraying 2 to 3 times, can effectively improve the photosynthetic efficiency of leaves, restore tree vigor, and increase tree nutrients. It can also add nutrients and promote vines.
Recycling basal fertilizer
The base fertilizer should be re-used before the deciduous leaves of the grapes. For trees with a result of more than 50 kilograms, 10 to 20 kilograms of human and livestock manure is prepared per plant, 1.5 to 2 kilograms of NPK fertilizer, and 0.5 to 1 KH2PO4. Kilograms, centered on grape plants, dig deep and 30 to 40 cm wide ring grooves 50 to 60 cm away from the plants. All fertilizers are mixed well and applied to the ditch, covered with soil.
Timely prevention and protection of leaves
After the grapes are harvested, they must continue to do a good job of preventing and controlling diseases and insect pests. Sprinkle a 0.8% to 1% aqueous solution of lime sulfur in time to the leaves and stems and leaves. After every 10 to 15 days, a 70% thiophanate-methyl WP wettable powder is sprayed once every 10 to 15 days to eliminate various pests that damage the leaves, and also to control leafhoppers and other pests.
Timely soil loosening and flood control
After picking, the soil is easy to be practical, and an cultivating soil should be immediately ploughed to increase the permeability of the soil. The deep ploughing can be combined with fertilization. The rainwater should be drained in a timely manner for a long time. In case of autumn or winter drought, it should be timely irrigated to maintain Suitable soil moisture.
