摘要
南疆枣园病虫害防治主要以喷洒农药为主,给红枣带来了农药残留,影响红枣品质。为了探索病虫害物理防治方法,结合南疆地区枣树生长环境,利用高压静电技术,设计一种枣园可控光引诱高压静电杀虫器装置。采用倍频放大电路,对高压静电发生器电路的优化计算,提高了静电输出带负载能力,优化了高压电的放电控制算法;利用单片机技术,通过升高杀虫电网电压,改进电网结构,加入智能安全保护等功能的设计。试验制作了1台试验装置,经试验测试,结果表明:该装置杀虫效率高,当放置位置恰当时不会对红枣与枣树产生伤害。当电网电压为7 KV时,30分钟时间内杀虫数量为最高,表明在合适范围内,电压等级越高,杀虫效果越好。枣园可控光引诱高压静电杀虫器装置具备可行性,能为大规模应用提供参考。
The main pests and diseases in jujube orchard in southern Xinjiang were mainly pesticide sprayed,which brought pesticide residues to jujube and affected the quality of jujube.In order to explore the prevention and control methods of disease and insect pests,combined with the growing environment of jujube trees in southern Xinjiang,a high voltage electrostatic insecticide device was designed by using high voltage electrostatic technology.Using the frequency doubling amplifier and the optimization calculation of the circuit of the high voltage electrostatic generator,the load capacity of the electrostatic output belt is improved and the discharge control algorithm of the high voltage power is optimized.1 test devices were made in the experiment.The test results showed that the device had high insecticidal efficiency and no harm to jujube and jujube tree at the time.When the grid voltage is 7 KV,the number of insecticides is the highest in 30 minutes,indicating that the higher the voltage level is,the better the insecticidal effect is.The controllable light attracting high voltage electrostatic insecticide device in jujube garden is feasible and can provide reference for large-scale application.
