不同除草剂对寒地湿润直播稻田杂草的防除效果及安全性评价
Weed Control Effects and Corp Safety of Different Herbicides in Wed Direct Seeding Rice Fields in Cold Region
摘要
Abstract
Weedsare is an important factor which influence the high and stable yields of direct seeding rice.In order to select the herbicides suitable for the wed direct seeding rice in cold region,different herbicides were chosen to investigate their control effects on weeds and safety on crop during rice growing season.The results showed that application of 40% bensulfuronmethyl·pretilachlor or 40% bensulfuronmethyl·pretilachlor add 38% bensulfuronmethyl·clomazone·pretilachlorbefore sowing,55% pyrazosulfuron-ethyl·pretilachlor or 55% pyrazosulfuron-ethyl·pretilachlor add 38% bensulfuronmethyl·clomazone·pretilachlor at 2-leaf stage of rice,480 g·L-1 bentazone add 36% mpca sodium monosultap·fluroxypyr at 5-leaf stage of rice,respectively,controlled weeds effectively.The results of seedling emergence,growth and development and yield of direct seeding rice showed that the application of those pesticides in wed direct seeding rice paddy fields had no damage to rice.关键词
