1、 Why don't you water it during flowering

Fruit setting is very important in the management of grapes. Generally, it is necessary to water once before flowering to ensure the humidity of the soil. Watering is not recommended when flowering, as long as the soil humidity is maintained at 50%. Because the temperature of the soil will decrease after watering, so the absorption capacity of the plant will also decrease, so the fruit setting rate of flowering will decrease within three days. Therefore, we must grasp the watering time and do not water indiscriminately

However, if the soil humidity is lower than 50%, it should also be replenished. At this time, small water should be poured. Drip irrigation can be used to let the water penetrate slowly. As long as the root is slightly wet, large water should not be poured

2、 What fertilizer should be applied when flowering

It consumes more nutrients during flowering, so it should be fertilized and supplemented in time. A week or so before flowering, boron fertilizer should be sprayed on the leaves, and high phosphorus fertilizer should be applied at the same time to promote flowering. In this way, the flowers will be healthier, the flower organs will develop better, and the fruit setting rate will be improved. In addition, fertilization treatment should also be carried out after flower failure to supplement nutrition, which is conducive to the later growth of fruits

3、 Other management of flowering period

In addition to watering and fertilizing during flowering, we should also pay attention to temperature. It likes temperature, and its warmth cannot be too low or too high. The temperature during the day is 28 degrees, and it is best between 16-18 degrees at night. Greenhouse cultivation should be ventilated frequently to make the air circulate better
