The management of grapes during the flowering period is very important and determines the amount of fruit. Top dressing is required before and after flowering, and boric acid should be sprayed before flowering. It likes a warm environment. During the flowering period, the temperature should be controlled at about 28 degrees during the day and between 16 and 18 degrees at night. When flowering, stop watering and reduce the humidity. In addition, the inflorescences should be thinned out during the flowering period, and thin and weak inflorescences should be thinned out. It is recommended to help with artificial pollination when the flowers bloom, which can increase the fruit setting rate.

1. Appropriate amount of top dressing

It consumes more nutrients during the flowering period. In order to meet the needs of flowering and fruiting, top dressing must be done before and after the flowering period. In addition, boric acid should be sprayed before flowering to increase the fruit setting rate. In order to reduce the consumption of nutrients, it is necessary to perform tasks such as topping, pruning the tips of the ears, and removing the tips in a timely manner.

2. Control temperature and humidity

It likes a relatively warm environment. During the flowering period, the best daytime temperature is around 28 degrees, and the night temperature is between 16-18 degrees. This temperature environment can promote better flowering. After the flowers bloom, the humidity should be controlled well. Watering should be stopped first. The humidity should be about 50%. Those cultivated in greenhouses should be ventilated frequently, and those cultivated in the open air should loosen the soil and take measures to reduce humidity.

3. Sparse inflorescences

Sparse The inflorescence should be determined according to the growth strength of the branches, and should be carried out from 10 days before flowering to the flowering period. There are more than two inflorescences on each fruit branch. Thin out the thin and weak ones. Finally, the strong fruit branches will have 1-2 inflorescences, the medium and strong branches will have 1 inflorescence, and the weak fruit branches will not need to keep the inflorescences.

4. Artificial pollination

It Although there are many varieties of flowers, most of them are bisexual flowers and can be fertilized naturally. However, some stamens will degenerate early and require pollination to ensure yield, so artificial pollination must be carried out in time.
