穆阳水蜜桃梨小食心虫绿色防控试验与集成技术

Green Prevention and Control Experiment and Integrated Techniques of Oriental Fruit Moth in Peach‘Muyangshuimitao’

为解决化学农药防治梨小食心虫易造成农药残留超标、害虫抗药性增强和果实品质下降等问题。于2016-2021年,对穆阳水蜜桃开展梨小食心虫绿色防控技术集成示范,结果表明,集成应用农业防治、生草栽培、生物防治、理化诱杀防控、科学用药等绿色防控技术的保梢和防控效果分别为93.00%和95.78%,与常规化学防治相比,示范区的果园天敌增加53.57%,平均产量增加5.84%、优果率提高9.69%、每667 m^(2)纯收入增加7225元,农药使用量减少20.5%,提升了果实品质,取得了较好的经济、社会和生态效益。

In order to solve excessive agrochemical residue,increased insecticide resistance to pests,fruit quality decline and others caused by chemicals preventing and controlling oriental fruit moth,the integrated demonstration of green prevention and control techniques of oriental fruit moth of juicy peach‘Muyangshuimitao’was conducted from 2016 to 2021.The results showed that shoot retention rate and prevention and control rate reached 93.00%and 95.78%,respectively when integrated green control techniques of agricultural control,sod cultivation,biological control,trapping control by physicochemical methods were applied.Compared with the conventional chemical control,nature enemies in the orchards of demonstration areas,average yield of peach,high-quality fruit rate and net income per 667 m^(2) were increased by 53.57%,5.84%,9.69%and 7225 yuan,respectively while application of agrochemicals were reduced by 20.5%.The integrated techniques could improve fruit quality,achieve good economic,social and ecological benefits.
