葡萄浆果生长发育期,包括幼果迅速膨大期、硬核期、浆果第二次膨大期、浆果成熟期,而幼果迅速膨大期是这一生育过程中最关键的一个时期,对葡萄产量和质量有着重大影响。此期应重点抓好以下管理技术措施的落实:1.疏果。疏果,根据果粒大小,分时进行,5~7天内完成,疏去不能正常发育的小果,保证果穗的整齐美观。早疏有利于果粒膨大。工序上应先整穗型疏去小穗轴,然后疏果粒,两项工序分开实施。疏果时,应用疏果 Grape growth and development, including the rapid expansion of young fruit, hard nuclei, the second expansion of the berry, berry ripening period, while the rapid expansion of young fruit is the most important period of this fertility period, the grape yield and Quality has a significant impact. This period should focus on the following management techniques and measures to implement: 1 thinning. Thinning fruit, according to the size of fruit, time-sharing, completed within 5 to 7 days, to the small fruit can not be properly developed to ensure that the ear neat appearance. Early thinning is conducive to fruit enlargement. Processes should be the first whole sparse sparse rachis axis, and then thin fruit particles, the two processes separately. Thin fruit, the application of thin fruit
