Prevention of grape secrets "secret recipe"

The large and round grapes are very popular among consumers in the market. However, in the process of planting the grapes, the management of the grapes is often not in place, resulting in the abortion of the grape seeds, resulting in a large number of small grains of the grapes. The method of preventing grape small grains will now be prevented. Explain as follows:

1. Take artificial ear: Take 1/5-1/4 of flower spikes 2-3 days before flowering.

2. Strengthen the management of fertilizer and water in the flowering period: Ensure that there is sufficient nutrients for the “critical period of fruit setting nutrition” and “critical period for seed development and nutrition” after the flowering.

3, regular pollination of grapes: In the early flowering period to the full flowering period of grapes, spraying 0.2% borax solution once every 7 days, and even spraying 2-3 times, to promote pollen tube germination, improve insemination rate.

4. Pruning and cutting of grapes in summer: The results will be picked from the beginning of flowering to full flowering. At the same time, all the lateral side shoots will be wiped off, leaving only one tip at the top. After 7 days, leave 1-2 leaves at the tip of the top tip. Two secondary shoots were germinated and wiped off in time.

In summary, it can effectively prevent grapes from producing small grains. First of all, grape management during the flowering period is ensured to ensure that the nutrients needed for grape growth are sufficient, so as to increase the insemination rate of the grapes, and pruning and topping can be done. This can reduce the grape granules. The production.
