Six measures for stable quality of grapes
In the grape production, there are common and easy results, and the early yield rises quickly. As a result, the tree vigor is easily weakened, and the result is that the parts move quickly outside, the yield is easy to fall, and the fruit quality is easily deteriorated. Therefore, stable production and high quality is the main direction of grape production. The following measures are conducive to the stable quality of grapes. First, control the amount of results. The result of the grape-vulnerability results in fruitful vineyards in the fruit period. The annual mu yield reaches 4,000 to 5,000 kilograms. This weakens the tree vigor and depletes the nutrient of the tree. As a result, the tree vigor is weakened, affecting the output in the coming year, and the result is too much. Fruit enlargement often results in small fruit size and poor quality. Therefore, the amount of results should be strictly controlled during production. In the full fruit period, the fruit yield per mu is controlled at about 3000 kg to ensure the stability of the yield and the quality of the fruit. Second, enough fat enough water to ensure nutrient supply. Fertilizer and water are the material basis of grape growth results. During the grape growth period, adequate fertilizer and water supply should be ensured. The following points should be noted in the management of grape manure: 1. Pregerminate the water before germination to make the shoots neat and consistent. 2. Control water and nitrogen after germination to flowering, so that the growth potential of new shoots will remain moderate, so as to benefit the results. 3. After the fruit is set, the fertilizer and water supply will be strengthened to prompt the rapid expansion of fruit and increase the yield. 4. Apply sufficient amount of fertilizer and water in time after fruit harvesting and supplement the nutrient consumed by the tree in order to restore the tree vigor. 5. Apply basal fertilizer before defoliation. Basal fertilizer is mainly farmyard manure. In the whole year's fertilization, the application amount of organic fertilizer per acre is 3000-5000 kg, urea 60-70 kg, calcium superphosphate 100-150 kg, and grass ash 2000. -3000 kg. 95% of total fertilizer is applied as basal fertilizer, organic fertilizer, phosphate fertilizer, and potassium fertilizer with late fertilizer are applied at the same time as base fertilizer, 80% of urea is applied at base fertilizer, and 20% of urea is applied at fruit enlargement period. . Third, strictly control the results of the site. Outward shift of the results is one of the main reasons for the low and unstable grape yield. Strengthen pruning in production, promptly cut off the old branches after the results, and cultivate new mother branches; strengthen pruning, and adopt measures such as single branch updates, two-branch updates, or multiple branch updates each year to strictly control the outward movement of the resulting parts and maintain production. Stability. Fourth, control the amount of branches. Grapes have many branching habits, a large number of secondary branch, three branches of the branch, consume a lot of nutrition, deteriorate lighting conditions, unfavorable stable production and high quality, strict control of branch production. For the auxiliary shoots, all the extracts below the ear were used, the space above the ear was reserved, the length of the space was small when the heart was picked up, and the space was removed when there was no space, ensuring good permeability of the tree and the garden and producing high-quality fruit. Fifth, strengthen the management of the ear. Before flowering, the branches were left inflorescence according to the growing trend. The strong shoots left double spikes, the golden mean branch left 1 ear, and the weak branches did not leave the ear. For the preserved inflorescences, the spikes and long spikes should be cut to facilitate the growth and development of the ear, and to promote fruit enlargement and produce high-quality fruit. Sixth, strengthen pest control. Diseases and insect pests affect photosynthetic development, hindering the accumulation of photosynthetic products, and strengthen the prevention and control of diseases and insect pests during production.
