The period of protecting flowers and fruits of grapes

The whole supply of nutrition should be ensured during the period of flower and fruit protection of grapes. Trace elements, boron and calcium elements can be used to promote division growth. This is more helpful for the follow-up fruit setting rate, and can also strengthen the growth structure of grapes.

Matters needing attention during the period of flower and fruit protection of grape

1. In order to protect flowers and fruits, grapes must first ensure the supply of nutrition. During this period, supplement trace elements, such as boron and calcium, because boron can promote the growth and development of pollen tubes and be of great help to the rate of fruit setting. Calcium fertilizer can promote the toughness of the fruit and the connection with the rhizome, strengthening the growth. Therefore, boron-calcium foliar fertilizer with the same supplement of calcium and boron can be selected in terms of nutritional supplement. Generally spray 3-5 times, you can achieve the effect of flower and fruit protection.

2. On the other hand, in terms of watering, do not pour water and apply it as few times as possible, which will be helpful to pollination. And do not choose to do it during the period of grape pollination, but to avoid the period of pollen pollination.

Generally speaking, the problems of grapes can be dealt with carefully, and there are basically no other major problems.
