Spring is the season when the grape buds spread out, and the elongation and heading and the flowering of the branches spread. Strengthening the spring management of grapes is of great significance to improving the current year's yield and quality of grapes. The full-scale clearing of the park will cut the diseased branches, diseased leaves, and diseased fruits during winter cuts, bring them out of the orchard and burn them or deepen them, reducing the source of overwintering. When 10% of buds germinate to 1 cm, choose sunny weather, spray 3~5 Baume degrees lime sulfur, and pay attention to bath spray. Precipitation of water with buds, quick-effect fertilizer In the seasons when grape flower buds differentiate and new shoots begin to thrive, grapes need a lot of nutrients, such as dry soil before germination, and conditional orchards should be filled with water in time to ensure budding and orderliness. Experiments over the years have shown that when 15,000 times of the seedlings are sprayed in the bud, they can regulate the balance of vegetative growth and reproductive growth, promote new shoot growth and robustness, and improve frost resistance. Spraying 6 grams of “Bui†in the early stage of grape blooming can not only reduce the size and size, increase the fruit setting rate, but also make the leaves thick and dark green, enhance photosynthesis, such as red to take medicine 10-15 days before flowering; Take medication 5 to 7 days before flowering. After 6 to 5 days of grape flowering, 6 grams of “Bi-care†is used for the reduction of physiological fruit drop and the improvement of disease resistance. The use of orchards that promote or shelter from raining will increase the growth period. In the spring, the following tasks should be focused on: 1. Pay attention to ventilation in the greenhouse. When the temperature in the shed reaches 30°C, it is necessary to open the door in time for ventilation. If the temperature is high, the skirt film on both sides of the greenhouse can be opened to reduce the temperature in the shed to about 25°C. 2. Weak tree top dressing. When the grapes are sprouted 7 to 10 days, the “Akie†organic whole nutrient fertilizer is applied to the young trees or old trees that grow weak.
