The coating hapten was bound to the surface of microparticles through avitin biotin reaction. An electrochemical flow cell containing working electrodes and counter electrodes for initiation of the ECL reaction was constructed. Results showed that the detection limit for methsulfuron methyl was 0.1 ng/mL. [WT5HZ]展开更多
1991~1993年对50个麦类品种和4个除草剂效应进行了研究。一种除草剂对不同的麦类品种在出苗数、百株苗分蘖数、百株苗鲜重的抑制率有差异,不同的除草剂对一个麦类品种也产生不同的抑制率。从中选出14个品种用甲黄隆超微WP ai 0.5g/666....1991~1993年对50个麦类品种和4个除草剂效应进行了研究。一种除草剂对不同的麦类品种在出苗数、百株苗分蘖数、百株苗鲜重的抑制率有差异,不同的除草剂对一个麦类品种也产生不同的抑制率。从中选出14个品种用甲黄隆超微WP ai 0.5g/666.7m^2进行喷雾处理作产量测定,增产率最高的是浙麦4号,为24.18%,增产率最低的是扬87—158,为0.67%。浙麦1号上几种除草剂的比较试验,增产率最高的是绿黄隆超微WP ai 0.75g/666.7m^2,为33.3%,增产率最低的是丁草胺60%EC75ml/666.7m^2,为16.8%。试验结果表明,甲黄隆在浙麦1号上的最佳施用期是播后芽前至一叶一心期,最佳施用量是ai 0.3~0.4g/666.7m^2。展开更多
