| 摘 要： | 对代森猛锌、乙撑硫脲在大棚、露地黄瓜上的残留动态进行了对比研究。喷药后，代森锰锌在大棚黄瓜上的降解动态方程为Ct=1.058e^-0.1282t，露地为Ct-0.751e^-0.4689t。半衰期分别为5．4d和1．4d。代森猛锌在大棚黄瓜上的降解速率要慢于露地黄瓜。乙撑硫脲在大棚黄瓜上的降解动态方程为Ct= 0.152e^-0.1794t,露地为Ct=0.059e^-0.1366t。半衰期分别为3．0d和5．4d。乙撑硫脲在大棚黄瓜上的降解速度要稍快于露地黄瓜。

| Abstract: | The residual dynamics of mancozeb and ethylenethiourea on cucumbers grown in plastic house and open field were compared After application, the dynamics of mancozeb residues on cucumbers grown in plastic house and field could be described, respectively, as C t =1 058e -0 1282t , C t =0 751e -0 4689t , with a half-life of 5 4 and 1 4 days, respectively The degradation of mancozeb on cucumbers grown in the plastic house was slower than that of cucumbers grown in open field The dynamics of ethylenethiourea residues on cucumbers grown in plastic house and field could be described, respectively, as C t =0 152e -0 1794t , C t =0 059e -0 1366t , and respectively with a half-life of 3 9 and 5 4 days The degradation of ethylenethiourea on cucumbers grown in the plastic house was faster than that of cucumbers grown in open field |
