Measures to improve the Commodity of Grape products

1. Ear fixing: leave a good ear with correct spike shape, uniform fruit setting and drooping posture. 2. Panicle shape arrangement: on the basis of conforming to the natural shape of varieties, the panicle shape of the same varieties in the whole garden should be basically the same. 3. Elongated inflorescence: for varieties with higher fruit setting rate, when the inflorescence is 7-10 cm long, 3-5 mg / L gibberellin is sprayed or dipped in the inflorescence to make the inflorescence elongate. For seedless varieties, 10 mg / L gibberellin is dipped in the ear after anthesis or 6-10 days after anthesis, which is beneficial to fruit. 4. Grain thinning: on the basis of thinning different shoulders and accessory spikelets, it is advocated to thinning spikelets mainly and supplemented by grain thinning. 5. Fruit enlargement: 10-15 days after the second treatment, 20-25 mg / L gibberellin plus 2 mg / L pixiuron was dipped in the ear to make the fruit bigger. 6. Bagging: bagging 2-3 weeks after anthesis. Two weeks before bagging, spraying twice (one week apart) 300 times calcium nitrate or 600 times humic acid beggars can relatively make up for the deficiency of bagged fruit due to lack of calcium, such as small fruit, low sugar, light flavor and poor storage tolerance. Choose bags of appropriate size, colorless, transparent, resistant to Rain Water erosion and with drainage holes. After bagging to check, found that there are wet bags, burst bags, broken bags and falling bags should be mended in time. In case of drought before removing the bag, the bag should be removed after watering, and the maturity should be divided into varieties, stages and batches during harvest to ensure the quality of the berries.
