【摘要】 为了避免农药残留带来的危害,采用高压静电放电法杀灭黄瓜植株害虫—瓜绢螟。设计传统农药灭虫和高压静电放电灭虫两个试验,用于对比、分析两种方法处理后的效果。结果表明,高压静电放电法灭虫率可达63.55%～70.44%,虽低于农药灭虫,但无毒无害,且对天敌瓢虫的影响不大。通过正交优化,确定最优灭虫电压、灭虫时间和灭虫距离,在最优参数下,对瓜绢螟杀灭率可达78%。更多还原

【Abstract】 To avoid the hazards of pesticide residues,this paper presents a method by using high-voltage electrostatic discharge to kill cucumber Diaphania indica.The traditional pesticides and high-voltage electrostatic discharge were designed to compare the effect of two ways of pest control.The study show that the rate of pest control by using high voltage electrostatic discharge method was up to 63.55%-70.44%,lower than the pesticide pest control,yet it is non-toxic,and has little effect on the natural enemies of the ladybug.Through orthogonal optimization,the optimal pest control voltage,pest control time and pest control distance were determined.The diaphania-killing rate with the optimal parameters is up to 78%.更多还原
