糜子草害防治研究

Exploration of Prevention and Control of Weeds on Broom Corn Millet

为了减轻在糜子生产中的成本投入和劳动强度,通过在糜子田间不同配比和方法施用不同除草剂并进行糜子田间草害防治效果和产量的比较、分析,筛选出4种可用于糜子的田间草害防治方法。用于防治禾本科杂草的方法是糜子除草关键,对禾本科杂草防治效果较好的除草剂有二氯喹啉酸、莎稗磷、丙草胺、扑草净、烟嘧磺隆、莠去津、二甲戊灵等7种,其中扑草净、烟嘧磺隆、莠去津、二甲戊灵4种除草剂还具有部分防治非禾本科杂草的功效。

In order to reduce costs and labor intensity in broom corn millet production,four control methods of weeds in broom corn millet field were screen out by spraying herbicide in different proportion and way to reduce cost input and labour intensity in broom corn millet.The results showed that control method of gramineous weed was the key of weeding in broom corn millet field.The herbicides those control efficiency were excellent included quinclorac,anilofos,pretilachlor,prometryn,nicosulfuron,atrazine and pendimethalin.Four of these herbicides included prometryn,nicosulfuron,atrazine and pendimethalin that possessed respectively different effect on controlling non-gramineous weeds.
