摘要
运城2005年苹果成花率低,多数果园只有2004年的1/4～1/5,不少果园还出现了“空树”现象,主要是由于2004年果树的各花芽分化阶段不良气候条件以及果树光合产物不足,致使花芽分化与果树花果之间产生了营养竞争而使得果树花芽分化受到了抑制,使得果树大部分花芽转向了叶芽,从而导致了2005年果树成花大量减少。
The main reason of low abloom rate of apple were bad climatic conditions in period of differentiation of flower bud pf apple and lack of photosynthesis product of apple which caused the nutrition competition between flower bud differentiation and the flower fruit and restrained the flower bud differentiation. Those caused the most flower bud changing to leaf bud and lead the reduction of flowering rate of apple in 2005.
