玉米是我县主要粮食作物,常年种植面积6万亩左右。为减轻草害对产量的影响,减少中耕除草的劳动力浪费,寻求高效、省工、安全的除草方法,我们于1991年4～8月进行了乙草胺不同剂量防除玉米地杂草的小区试验,结果简报如下。 一、试验材料及方法 (一)供试药剂:50％乙草胺乳油,昆山化工厂生产。 Corn is my county’s main food crops, perennial planting area of ​​60,000 acres. In order to reduce the impact of grass-planting on the yield, reduce labor waste and to seek efficient, labor-saving and safe weeding methods, we conducted a community trial of different doses of acetochlor to control weeds in the cornfield from April to August 1991 The result briefing is as follows.
