| 摘 要： | 本文研究了敌百虫对山地国光苹果的疏果效应。结果表明,国光苹果采用盛花后10d喷布900～1125mgL~(-1)的敌百虫,疏除效应显著。喷布1125mgL~(-1)的敌百虫加萘乙酸20mgL~(-1),可使幼果脱落推迟,疏除作用增强。处理后,果实的单果重及第2a的花芽量增加。

| Abstract: | The fruit thinning effict of dipterex was investigated on "Rails" apple trees in mountainous area, The result showed that dipterex applied 10 days after full bloom at concentrations between 900 and 1125 mgL-1 possesed significant fruit thinning effect on "Rails" apples. The addition of NAA 20mg/l enhanced the thinning effect of dipterex; but delayed the abscission of young fruits. The individual fruit weight at harvest and the amount of flower buds appearing in the next spring were increased after spraying. |
