梨树由于受环境条件影响,使当年分化的花芽在秋季就开放,消耗树体的养分,影响次年春季开花量,导致落花落果。本场1969年栽的梨树,1978年就发现秋季开花现象,近年来更加严重。据1982年8月份的调查结果,全场9,241棵梨树中,有8,056棵梨树在当年秋季开花,占梨树总数的88.2％。1982年8月15日对180株梨树的抽样调查,平均一棵梨树上秋季开花量达1,020朵,其中最多的达1,562朵,最少的为53朵。为了弄清楚梨树秋季开花的原因,笔者二年来先后到贵溪塔桥园艺场、进贤永桥农场、九江茅山头垦殖场等梨树主产地进行调
Pear tree due to environmental conditions, so that the differentiation of flower buds in the open on the opening, consumption of tree nutrients, affecting the amount of flowering the following spring, leading to fall and fall.
