What should you do if there are many small berries in grapes? What methods can prevent small berries in grapes? We would also like experienced netizens to share their methods.Large, round grapes are very popular with consumers on the market, but during the process of growing grapes, inadequate management often leads to grape seed abortion, resulting in a large number of small berries. Therefore, Zhongdi Web has compiled methods to prevent small berries in grapes, listed in detail below for netizens' reference.
Step 1,Carry out manual cluster thinning: 2-3 days before grape flowering, remove 1/5-1/4 of the flower cluster.
Step 2,Strengthen the management of fertilizer and water during the grape flowering period to ensure sufficient nutrients during the "critical period of fruit-setting nutrition" and the "critical period of seed development nutrition" after the start of flowering.
Step 3,Pollinate the grapes regularly. From the early flowering stage to the full flowering stage of grapes, spray a 0.20% borax solution once every 7 days, for 2-3 consecutive sprays, to promote pollen tube germination and improve the fertilization rate.
Step 4,Prune and train the grapevines in summer. From the start of flowering to the full flowering stage, pinch the fruiting shoots, and at the same time remove all lateral secondary shoots, leaving only 1 secondary shoot at the top. After 7 days, pinch the top secondary shoot again, leaving 1-2 leaves. If secondary shoots sprout a second time, remove them promptly.
Referring to the above steps can effectively prevent grapes from producing small berries. First, do a good job in managing the grape flowering period, then ensure that the nutrients needed for grape growth are sufficient, thereby improving the grape fertilization rate, and do a good job in pruning and pinching. In this way, the occurrence of small berries in grapes can be reduced.
