今年,我市苹果树多为大年,在加强综合栽培管理的基础上,如何搞好疏花疏果,是保证今年苹果丰产、优质的关键。化学药剂疏花疏果,最适于大面积果园应用,方法简单,可提高工效15倍以上,稀果效果也较好。另外,近年来发现乙烯利、萘乙酸等稀果药剂还有一定的促花作用,明显地提高下年结果量。 This year, the apple-bark of our city is mostly New Year’s Eve. On the basis of strengthening comprehensive cultivation and management, how to do a good job of thinning and thinning fruit is the key to ensure the high yield and high quality of this year’s apple. Chemical thinning thinning fruit, the most suitable for large area orchard application, the method is simple, can improve work efficiency more than 15 times, fruit thinning effect is better. In addition, it has been found in recent years that ethephon, naphthaleneacetic acid and other thinning medicaments have a certain effect of promoting flowers and apparently increasing the amount of next year’s results.
