From November to December, as the temperature decreases, grape growth begins to enter a dormant period. This is a relatively easy time for production management. Many growers tend to overlook field management. Zhang Zongqin, an associate professor at the Forestry College of Northwest Agriculture and Forestry University, reminded farmers that during the period, vineyard management still cannot be relaxed, and it is necessary to pay close attention to the following tasks:
When collecting planting strips and preparing to expand the planting area and new gardens, it is necessary to grasp the planning of the gardens, land consolidation, and the implementation of seedlings; in the gardens with nursery production, it is necessary to grasp the collection of planting strips. The mother tree from which the species is collected shall be a mother tree that is pure, robust, and has good traits and no pests. The collected species should be ripe and full of shoots. The collected species should be labelled in a timely manner and properly kept. The best time to grasp the winter pruning winter pruning grape during the winter is to enter the dormancy period to about 20 days before the injury period. Cultivation of greenhouses should be completed before the film is trimmed.
The base fertilizer for autumn basal fertilization should be dominated by organic fertilizers, and attention should be paid to the reasonable combination of the three elements of nitrogen, phosphorus, and potassium. Generally, about 2000 kilograms of decomposed livestock and poultry manure, 25 kilograms of compound fertilizer, and 50 kilograms of superphosphate are used in Mushi. At the same time, according to the different shortages of the fields, other phosphorus and potassium fertilizers and trace element fertilizers were added. The application method of basal fertilizer is divided into two types: garden application and ditch application. In general, the grape used in the scaffolding is applied in the whole garden, and the fertilizer is spread after the application of the fertilizer. Gully application can be determined according to the age of the tree, and fertilization can be applied in the annular groove or strip groove. The ditch depth and ditch width should be reasonable. Fertilizer applied after soil coverage.
Thoroughly clean the garden and remove the grape leaves, tendrils, fruit stems, fallen fruit, dead branches, and weeds that have fallen off from the garden. If the bark of the main trunk is tilted, it is necessary to grasp the stripping work of the old skin so as to remove germs and insect pests on the trunk and reduce the incidence of diseases and insect pests in the coming year. The peeled-off old skin should be burned and disposed of. After peeling the old skin, the whole garden was painted with a white trunk, and the agent was mixed with lime and lime to form a paste, and the trunk was brushed. The entire garden was sprayed with a disinfection and sterilization agent to eliminate pests and diseases.
