摘　　要：通过对两个香料烟主产区苗床杂草的调查,明确了冬春香料烟苗床主要杂草的种类及其萌发规律。防效试验的结果表明,播种前7 d,用50%萘丙酰草胺(大慧利)400倍液喷雾处理苗床土壤1次,外加塑料薄膜覆盖保湿7 d后再播种,防除单子叶杂草效果达90%以上,防除双子叶杂草效果达70%以上。The weeds variety in the seedbed and their germination dynamics were studied by investigating two main oriental-tobacco producing areas.The results indicated that 400 times of 50 % napropamide could control more than 90 % monocotylous weeds and 70 % dicotylous weeds when it was sprayed on the seedbed plus plastic mulching before seeding for 7 days.
