耕翻麦田使用绿麦隆,由于土壤、气候、使用技术等因素的影响,防除看麦娘的效果在年度间、田块间不够稳定。从1983年起,结合麦田免(少)耕技术的推广,用绿麦隆可湿性粉剂与3厘米表土混合,即稻板田机开沟、盖籽机碎土、播种、施药、盖籽机盖籽混药,进行防除看麦娘的试验,并逐步在生产上推广,取得了较显著的效果。 (一)免(少)耕浅层混药的效果常州市郊区刁庄乡1984年大而积示范推广免(少)耕,用绿麦隆浅层混药防除麦田看麦娘以来,仅5年的时间,看麦娘发生基数显著下降。据刁庄乡农场调查,1984年夏熟田间看
Tilling over wheat fields with chlorotoluron, due to soil, climate, the use of technology and other factors, the effect of controlling Amarillo looked at in the year, between plots is not stable enough. Since 1983, combined with the promotion of wheat-free (or less) tillage technology, it was mixed with 3 cm topsoil with chlorotoluron wettable powder, ie rice paddy field machine ditching, cover machine soil breaking, sowing, spraying, Cover seeds mixed drugs, prevention and control of Anemarrhenae test, and gradually promote the production, and achieved more significant results. (A) free (less) the effect of tilling shallow mixing Changzhou suburbs Diao Zhuang 1984 large and plot plot to promote exemption (less) plowing, Year, see Amy declines significantly. According to Diaozhuang farm survey, summer field cooked in 1984 to see
