在劳力紧缺、大面积植株高大的果园里,果树“计划”生产,可选好用好药剂疏花疏果、控梢保果。常用的药剂如下: 一、快绿丰:每包40克对15千克,加糖50克,阿斯匹林4片,维生素B_24片。先用少量水溶解,再加入适量清水,搅拌均匀,喷施叶片背面。晴天上午9点前,下午4点后喷施,阴天不限。分别在果树谢花后、春叶展开期、果实膨大期使用。能提高果树对太阳能的转换率,促使叶片从空气中吸收气态氮和气态水,特别抗高温干旱、阴冻害和病害,减少农药、水、肥用量。使果树不但能承受大年的营养消耗,还能
In the labor shortage, a large area of tall orchards, fruit trees “plan ” production, easy to use good drug thinning fruit thinning, control tips. Commonly used agents are as follows: First, fast green abundance: 40 grams per pack of 15 kg, 50 grams of sugar, aspirin 4, vitamin B_24 tablets.
