水稻病虫害防治技术,历来采用低浓度药液直射喷洒法。此法用水量大花工多,且对防治水稻后期病虫害效果不理想。此外这种方法用机械喷(弥)雾成本高,维修技术难,一家一户经营者难以接受。为改变这种状况,本人经10多年试验摸索,采用浓缩液低喷雾技术,效果很好。本办法用普通背包式喷雾器,家家户户都可采用。它比低浓度直喷法省时3/4,而防治效果却提高2.5%。
Rice pest control technology, has always been using low concentrations of liquid direct spraying method. This law with large flowering workers, and the prevention and treatment of pests and diseases late rice is not ideal. In addition, this method of spraying with mechanical (Mi) high cost of fog, maintenance of technical difficulties, one family business operators unacceptable. To change this situation, I grope for more than 10 years of testing, the use of concentrated liquid spray technology, the effect is very good. This approach with an ordinary backpack sprayer, every household can be used. It saves 3/4 of the time compared to the low concentration direct injection method, while the control effect is increased by 2.5%.
