How to improve the commerciality of grapes directly affects the production of grapes. There are many factors affecting the merits of the grape products, such as climatic conditions, varieties, yield per unit area, cultivation measures, etc. Now on the cultivation and management to introduce some practical measures to improve the quality of grape significantly promote. 1, to increase the rate of fruit set: This is mainly used for tetraploid varieties such as Kyoho, which are easy to fall and fall, and diploid varieties do not apply. Spraying 7-10 days before flowering 300 times a B_9, or 25% mepiquat chloride 40ml / mu, combined with pre-flower pre-anthesis, flowering topping can increase fruit set rate of 20% -60%, to promote the spike compact
