摘要:

為了控制和防止蝗災(zāi)大面積爆發(fā),，開發(fā)了高壓靜電噴灑滅蝗車,。考察了雙流體霧化噴嘴各控制參數(shù)之間的相互關(guān)系,，發(fā)現(xiàn)改變氣液壓力配比可以有效調(diào)節(jié)雙流體噴嘴的噴量和霧滴粒徑,。在此基礎(chǔ)上，對(duì)高壓靜電噴灑滅蝗車進(jìn)行霧滴沉積特性試驗(yàn)和草原滅蝗試驗(yàn),，霧滴粒徑和沉積分布在射程方向上呈現(xiàn)雙峰特性,，蝗蟲殺滅率可達(dá)93％，喂毒性藥劑的滅蝗效果比觸殺性藥劑好,。

Abstract:

A high voltage electrostatic spraying vehicle was developed to control locusts in agriculture and stockbreeding. The experiment of two-fluid spray nozzle was carried out and the relationship of control parameters was obtained. It was found out that the liquid flow and droplet diameter could be adjusted by changing the proportion between gas pressure and liquid pressure. Meanwhile, the integrated vehicle experiment was conducted to get vehicle characteristics and locust-killing effects. The experimental results showed that droplet diameter distribution and deposition distribution had two peaks in spraying direction, the locust-killing rate of the vehicle could reach 93%, and locust-killing effect with absorbing pesticide was better than that with touching pesticide.
