Grapes are formed as a result of seed abortion. The number of mature small granule seeds and the number of large granule seeds are equal, but the small granule seeds are all in the young stage and are small but non-renal. So, how to prevent grapes from producing small particles?
The management of fertilizer and water is strengthened during the flowering period. Ensure that there are sufficient nutrients for the "critical period of fruit set nutrition" and "critical period for seed development and nutrition" after the initial flowering.
Flower pollination. From the early flowering stage to the full flowering stage, spray 0.2% borax solution once every 7 days, and spray 2-3 times, to promote pollen tube germination and improve the fertilization rate.
Strengthen summer cuts. From the beginning of flowering to the full flowering stage, the result of the branch was topping and removing all the lateral side shoots, leaving only one tip at the top, and then leaving 1-2 leaves for the tip of the top tip after 7 days. If it sprouts 2 times, it will be timely. Erase.
Artificial spike tips. Remove 1/5-1/4 of flower spikes 2-3 days before flowering.
