在集约化果园中,苹果和梨的稳产是建立在适宜生长环境(生长枝占20%左右)开放的花朵数与萌发的叶芽数量相等的基础之上的。这个指标和花芽占总萌发芽数的13~21%是一致的。
In intensive orchards, the stable production of apples and pears is based on an equal number of open flowers and sprouted buds in suitable growing environments (about 20% of the growing branches are open). This indicator is consistent with 13-21% of the total sprouted buds.
