Grape is a very common fruit in our daily life. At the same time, it is sweet and sour, the juice is delicious and nutritious. However, in the process of grape planting, there are still many things to pay attention to. At the same time, if the fruit setting rate of grapes is low, we need to improve the fruit setting rate by artificial pollination, spraying boric acid and urea mixture on the leaves and reasonable flower thinning. There are many factors that affect the color and green of grapes, so we should pay attention to the temperature and humidity of grape planting and the prevention and control of pests and diseases in the breeding process.

1. These three methods can improve the fruit setting rate of grapes.

If the fruit setting rate of grapes is too low, choose the sunny morning in flowering period, gently shake the wire on the shelf after the dew dries, and artificially assist grape pollination. In addition, spraying a mixture of 0.2% boric acid and 0.3% urea once before 10 day and at the initial flowering stage to supplement the nutrition of grapes can also significantly improve the fruit setting rate of grapes. Finally, 7~ 10 days before flowering, the top of the inflorescence was reduced by 1/4, and the poorly differentiated accessory panicle was removed to shape the inflorescence. Strong branches can leave two inflorescences, fruit branches leave one inflorescence, and weak branches leave no extra flowers, which improves the fruit setting rate.

Second, we must pay attention to these when planting grapes.

26~30℃ is the most suitable temperature for grape flowering. Once the temperature exceeds 30℃, the fruit will decline, and if it exceeds 35℃, the decline will be serious. At the same time, too dry or too wet soil will lead to serious fruit drop at flowering stage, so try not to fertilize, spray or irrigate at flowering stage. When planting grapes, it is necessary to prevent and control pests and diseases, and control the effects of gray mold and brown blight on the fruit setting rate of grapes. Pruning before flowering is also beneficial to fruit setting, and pruning after flowering will increase fruit drop. Finally, if the tree is too strong, the fruit drop will be more serious, so many grape plantations do not fertilize before flowering and wait until the fruit is set.

Strictly following the three methods mentioned by Bian Xiao can improve the fruit setting rate of grapes. At the same time, in the process of grape planting, we must pay attention to its living habits and these matters, so that grapes can bear more fruits.
