近年来,提高了油菜复种指数,造成田间杂草基数不断增加,也影响油菜产量。为此,在1983年冬种我们用48％氟乐灵乳油,50％杀草丹,60％的灭草特乳油做了油菜田化学除草试验,并取得较好的除草效果,初报如下: 直播油菜试验 分别以每亩商品氟乐灵100毫升混土,100毫升不混上,150毫升不混土的氟乐灵(商品量下同);100毫升,150毫升,200毫升的杀草丹;75毫升的灭草特和对照共8个处理。供试品种九二—13系(下同)。播种后当天傍晚用工农16型喷雾器每亩兑水100斤喷细雾,施药时土壤含水量23％。处理后38 In recent years, increased rapeseed multiplication index, resulting in an increasing base of weeds in the field, but also affect rapeseed production. For this reason, in the winter of 1983, we used 48% trifluralin, 50% diltiazem and 60% imazapyr to do the chemical weeding test in rapeseed field and achieved good herbicidal effect. The preliminary results are as follows: Live rapeseed trial respectively with 100 ml of product per acre of trifluralin, 100 ml is not mixed, 150 ml of non-mixed trifluralin (the same amount of goods); 100 ml, 150 ml, 200 ml of herbicide Dan ; 75 ml of herbicide and control a total of 8 treatment. Test varieties nine two -13 series (the same below). On the evening after sowing workers and peasants 16 type sprayer per acre watered 100 kg spray mist, spraying soil moisture 23%. After treatment 38
