Grapes are formed as a result of seed abortion. In general, the number of mature small granule seeds is equal to the number of large granule seeds, but the small material seeds are all in the young stage, small and non-human. If there is a mature seed in the fruit, the fruit can be slightly larger; when there are 2 mature seeds, the fruit can grow into a medium size; when there are 3 mature seeds, it can develop into normal large particles. fruit. The following points prevent the grapes from producing small particles: 1. Strengthen the management of fertilizer and water during the flowering period to ensure that there are sufficient nutrients for the "critical period of fruit setting nutrition" and the "critical period for seed development and nutrition" after flowering. 2. In the early flowering period to the full flowering period of grapes, spray 0.2% borax solution once every 7 days, spray 2-3 times, promote pollen tube germination and increase fertilization rate. 3, strengthen the summer cut. 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 the second tip is sprouted again, it will be timely. Erase. 4, artificial axillary spike. 1/5-1/4 of spikes were removed 2-3 days before flowering. This measure has obvious effects on the rose and new rose varieties, and has a high rate of spike formation and a large spike size. 4-Amino-6-Chloro-1,Benzoic Acid,Cas 761446-44-0 Shijiazhuang Dingmin pharmaceutical Sciences Co.,Ltd , https://www.dingminpharma.com
