苹果树进入盛果期形成大量的花芽,结果过多,品质下降,形成大小年的现象。为使苹果树优质高产,进行疏花疏果,是一项不可缺少的技术措施。我们于1999～2000年在10年生的红富士苹果树上进行了一次性疏蕾定果试验,比常规疏花疏果(花前疏一次花,坐果后疏一次果)简便易行,达到了优质高产的目的,有很大的推广前景。 Apple trees into the fruitful period to form a large number of flower buds, the result is too much, the quality of decline, the size of the phenomenon of the formation of years. To make high quality and high yield apple trees, thinning fruit thinning, is an indispensable technical measures. We conducted a one-time bud-setting experiment on Red Fuji apple trees from 1999 to 2000. Compared with the conventional thinning and thinning of flowers (one flower after flowering and one fruit after setting), we reached the conclusion The purpose of high quality and high yield, there is a great promotion prospects.
