旋耕机条播种麦杂草出草基数大,尤其是看麦娘,每平方米高达3700多株,是麦苗的10多倍,对麦子高产构成严重威胁。为寻求高效节本、方便适用的防除措施,1988、1989年秋播,我们用绿麦隆拌化肥浅层施药,进行防除看麦粮的试验示范,取得成功。 材料与方法 试验分设不同用药量与不同用肥量。
Rotavator sowing wheat weeds drafting a large base, especially to see Ma Niang, up to more than 3700 per square meter strains, is more than 10 times the wheat seedlings, a serious threat to the high yield of wheat. In order to seek efficient and cost-effective, convenient and suitable control measures, autumn planting in 1988 and 1989, we used the compound fertilizer of chlorotoluron for shallow application and carried out the experiment and demonstration of prevention and control of the wheat grain and achieved success. Materials and methods The experiment is divided into different doses and different amounts of fertilizer.
