| 摘 要： | 敌百虫对国光、金冠苹果疏果效应的研究结果表明,国光盛花后10d 喷布1125mg·1~(-1)敌百虫或加20mg·1~(-1)NAA;金冠盛花后12d 喷布900mg·1~(-1)敌百虫或加10mg·1~(-1)NAA,疏除幼果效应显著.果实单果重、翌年花量增加;果实品质、经济效益提高;大小年幅度降低.

| Abstract: | The fruit thinning effect of dipterex was investigated on Ralls and Gold Delicious appletrees.Results showed that dipterex applied 10 days after full bloom at concentrations 1125mg·I~(-1) with or without NAA in 20mg·I~(-1) showed significant fruit thinning effect on Rails ap-ple.The dipterex applied 12 days after full bloom at concentrations 900mg·I~(-1) with or with-out NAA(10mg·I~(-1))were effective for Golden Delicious apples.The mean fruit weight atharvest and the flowering in the following spring were increased;the fruit quality and econo-my benefit were improved;the range of alternation of the yield was reduced by the spray. |
