摘要
育苗移栽油菜三叶期以及直播油菜三叶期和蕾薹期喷施１５０ｍｇ／ｋｇ多效唑药液７５０ｋｇ／ｈｍ２，收获时油菜种子和土壤中均检测不出多效唑残留。在喷后２０ｄ其降解率达５０．６％。施药后土壤容重略有偏高趋势，对ｐＨ值影响不大，抑制细菌、真菌生长，对放线菌影响不大。
Spraying 150mg/kg paclobutrazol (MET) 750kg/hm2 on
rapeseed plant either in 3-leaf stage of seedling growing in seedbed and field or in belting
stage,no paclobutrazol remains were detected in rape seeds andsoil.Twenty days after
spraying,thedecomposing rate of paclobutrazol redched 50.6%.Spraying of paclobutrazolcaused
slight increase of the soil unit weight,but no significant effect on soil pH value. The growth of
bacterium andfungus was fnhibited,but the growth of actinomyces was not
affected.
