我县属里下河粘土稻麦区,看麦娘是麦田草害中发生面最广、为害最重的杂草之一。多年来在药剂防除上效果很不稳定。84年秋播期间,我们对看麦娘的防除进行了不同施药方法的比较试验,结果表明:用泼浇法在播后苗前到立针期施药,平均防效可达80.5—93.7%,比喷雾法提高一倍左右。 1.播后苗前喷雾(每亩用量100斤)在土壤干旱情况下只有25%的效果。
My county belongs to the Lixiahe clayey paddy and rice area, and it is one of the most weed-damaging weeds that occur in the rye field in the wheat field. Over the years in the pharmaceutical control effect is very unstable. During the autumn seasons of 1984, we conducted a comparative experiment on different methods of application to control Amanita. The results showed that the average anti-efficacy was 80.5-93.7% , About double the spray method. 1. After sowing seedlings before spraying (100 kg per mu) in the case of soil drought, only 25% of the results.
