近年来,水稻半旱栽培在我省(特别是丘陵区常年坐兜田)推广面积正在逐年扩大。随着栽培方式的改革,对防治水稻螟虫的施药方法必须相应改变,1983年我县对一、二代二化螟田间进行了不同施药方法的对比试验: 1、防治一代二化螟,在同一块田,采用两种施药法,亩施3％呋喃丹颗粒剂4斤,加细泥土60斤混匀搬施毒土,用25％杀虫双水剂0.4斤加水100斤手动喷雾相比,结果撒施毒土防效比喷雾低13.63％。 2、防治二代二化螟,同一田块,用25％杀虫双水剂亩用0.4斤,分别用毒土法、泼浇法、喷雾法等三种不同施用方式进行
In recent years, semi-arid rice cultivation in our province (especially perennial Hodian Podiatry) to promote the area is expanding every year. With the reform of cultivation methods, the application of pesticides to rice stem borers must be changed accordingly. In 1983, the county carried out comparative tests on different application methods for the first and second generations of rice stem borers: 1, In the same field, using two kinds of pesticide application method, Mushi 3% carbofuran granules 4 pounds, plus fine soil 60 pounds mix and move the soil, with 25% insecticide double agent 0.4 kg plus water 100 kg manual spray Compared with the results of spraying poison soil control effect is 13.63% lower than the spray. 2, prevention and control of the second generation Chilo suppressalis, the same field, with 25% insecticide Shuangshuu mu 0.4 kg, respectively, with toxic soil method, pouring pouring method, spray method, such as three different modes of application
