种玉米诱虫带,是防治玉米螟、高粱条螟危害棉花的好办法,简单易行,效果显著。1983年县科委,县植保公司、省农林科学院植保所,在葛岗公社的赵岗、葛岗等大队的3,000亩棉田上进行推广,据多点调查,种玉米诱虫带的棉花被害率为0.5％,玉米被害率为18％,而没种诱虫带的棉花被害率5.3％。1983年皮棉平均单产171斤,较1982年每亩增产64斤,比1983年全县平均单产增加17.2斤。诱虫带为每四平方米种一棵玉米,每亩150株左右,棉花出土后进行点种,玉米螟危害盛期过后拔除。既不影响棉花生长,又能大大压低玉米螟、高粱条螟对棉花的危害,是一种行之有效的措施。
It is a good way to prevent and control corn borer and sorghic stem borer, which is very easy to get rid of cotton. In 1983, the county Science and Technology Commission, the county plant protection company, the Provincial Plant Protection Academy of Agriculture and Forestry, in the Ge Gang commune Zhao Gang, Ge Gang brigade of 3,000 acres of cotton to promote, according to more surveys, Was 0.5%, corn damage rate was 18%, while the kind of insecticide zone cotton damage rate of 5.3%. In 1983, the average yield of lint was 171 kg, an increase of 64 kg per mu in 1982, an increase of 17.2 kg from the average yield of the county in 1983. Trapping insects with a per square meter of a type of corn, about 150 per acre, cotton unearthed after the point, corn borer damage after the peak period of the removal. It does not affect the cotton growth, but also greatly reduce the corn borer, sorghic stem borer damage to cotton, is an effective measure.
