Effects of Different Flower Thinning Agents on Apple Flower Thinning
摘要
Abstract
Thinning flowers and fruits,as one of the essential management practices in orchard production,plays a crucial role in regulating the fruit load of apple trees,alleviating the phenomenon of alternate bearing,increasing the proportion of high-quality fruits,and achieving the goals of intensive,efficient,and stable production.Currently,in the Longdong region of the Loess plateau,flower and fruit thinning is predominantly conducted manually,which is labor-intensive and time-consuming.Chemical flower thinning offers an effective alternative that can overcome the limitations of traditional manual methods and significantly reduce labor costs.This study was conducted in the major'Fuji'apple-producing areas of eastern Gansu province on the Loess plateau,aiming to evaluate the effects of different concentrations of chemical thinning agents on flower thinning efficacy such as lime sulfur(LS),ethephon(ETH),and ammonium thiosulfate(ATS).The results indicated that treatments with 1％LS and 1.2％ATS achieved inflorescence fruit set rates of 52.06％and 51.82％,respectively,and flower fruit set rates of 19.67％and 18.51％,respectively.These outcomes were superior to those of other treatments.These two agents are highly effective options for chemical flower thinning,the Longdong region of the Loess plateau.关键词
