摘要：本实验以绿萝为材料，以绿萝株高、新增茎叶重量等指标为标志，研究低剂量百菌清、生根粉对绿萝生长的刺激效应，探讨农药与植物生长之间的关系，以期为农药的生态风险评估提供依据。实验结果表明，150mg/kg生根粉对绿萝茎叶新增鲜重有显著的影响，同对照对比，处理60天后，绿萝茎叶新增鲜重1093.10%，百菌清对绿萝茎叶新增鲜重无显著刺激作用。200mg/kg生根粉对绿萝根长有显著的影响，同对照对比，处理60天后，绿萝根长减少76.07%，百菌清对绿萝茎叶新增鲜重无显著刺激作用。200mg/kg百菌清和200mg/kg生根粉对绿萝根鲜重有显著的影响，同对照对比，处理60天后，绿萝根鲜重分别减少62.04%与66.56%。61782

Chlorothalonil and abt money plant growth impact
Abstract: This experiment with other material, with other indicators such as plant height, the new leaf weight as the sign, the low dose of chlorothalonil, abt on money plant growth stimulating effect, to explore the relationship between pesticides and plant growth, in order to provide the basis for ecological risk assessment of the pesticide.Experimental results show that 150 mg/kg abt the new the money plant leaf fresh weight have a significant impact, compared with controls, processing after 60 days, new the money plant leaf fresh weight, 1093.10% chlorothalonil on other new fresh stem leaf ChongWu stimulation significantly.200 mg/kg abt the money plant root length have a significant impact, compared with controls, processing after 60 days, money plant root was decreased by 76.07%, chlorothalonil on other new fresh stem leaf ChongWu stimulation significantly.Chlorothalonil 200 mg/kg and 200 mg/kg abt has a significant effect on other root fresh weight, compared with controls,
processing after 60 days, money plant root fresh weight decreased by 62.04% and 62.04% respectively.
