3种化学药剂对皇家嘎啦苹果的疏果效果
Fruit Thinning Effect of Three Chemical Agents on the Royal Gala Apple
摘要
Abstract
Using 7-year-old Royal Gala apple trees cultivated by Zhaotong Haisheng Modern Agricul-ture Co.,Ltd.as test materials,three thinning agents—Metamitron,6-BA,and NAA—were sprayed to study their effects on the fruit thinning of Royal Gala apples,followed by data analysis and comprehensive evalua-tion.The following results were observed:All three thinning agents exhibited varying degrees of thinning ef-fect on Royal Gala apples;among them,6-BA demonstrated demonstrating the best overall performance,achieving the most desirable rates for blank clusters,single-fruit clusters,double-fruit clusters,and multi-fruit clusters,which were 34.67%,41.50%,31.40%,and 27.13%,respectively;compared with the un-treated control(CK),the single-fruit cluster rate and double-fruit cluster rate increased by 29.45%and 5.88%,respectively,while the multiple-fruit cluster rate decreased by 35.30%.The results indicate that chemical fruit thinning is both cost-effective and highly beneficial.It is necessary to conduct more extensive research on the application of 6-BA for flower and fruit thinning in Gala apples.关键词
