花芽数量的多少,和花芽发育质量的好坏(与座果率有密切关系),对产量有着重要影响。在生产中,也常常是实施花果管理、修剪、施肥的重要依据。花芽数量,常以具有顶花芽的花枝占总枝数的比例,即花枝率表示。据烟台地区果树实验站研究,苹果的盛果期大树,在枝量充足的基础上,花枝率达到30%以上的,花量比较适宜。河北省昌黎果树所的研究表明,在金帅、赤阳、国光、胜利、葵花、国庆等品种的5—7年生树上,花枝率为30—50%时,基本能够实现高产、稳产。花芽的发育质量,除了根据芽子的饱满程度、大小等形态特征加以判断以外,更可以利用芽子纵
The number of flower buds, and the quality of flower bud development (which is closely related to the fruit set rate) have an important effect on the yield. In production, it is also often an important basis for the implementation of flower management, pruning and fertilization. The number of flower buds, often with the top flower buds in the total number of branch branches, that is, squid rate. According to the research of fruit tree experimental station in Yantai area, apple’s fruitful period of large tree, on the basis of sufficient quantity of branches, the rate of flowering branches reaching more than 30%, the amount of more appropriate. The research on fruit trees in Changli of Hebei Province shows that when the flowering branches rate is 30-50%, the yield, stable yield can basically be achieved in 5-7-year-old trees such as Jinshuai, Aoyang, Guoguang, Shengli, Sunflower, and National Day. The quality of flower bud development, in addition to the full extent of bud according to size, size and other morphological characteristics to be judged, but also the use of bud longitudinal
