【摘要】 通过室内盆栽实验，测得土壤中莠去津对大白菜、黄瓜、油菜、甘蓝、番茄的安全浓度分别为０．０８０、０－０９１、０．１０２、０．１０４ 和０－１２６ｍｇ／ｋｇ，死亡浓度皆为０－４ｍｇ／ｋｇ。当土壤中莠去津含量低于安全浓度时，促进其生长，而高于安全浓度时，则抑制生长更多还原

【Abstract】 Greenhouse experiments of the safe concentration of atrazine in soil to Chinese cabbage,cucumber,rape,cabbage and tomato were conducted,the result indicated that,the safe concentrations of atrazine in soil were 0.080,0 091,0.102,0.104 and 0.126mg/kg respectively.The total lethal concentrations of five vegetables were 0.4mg/kg.If the concentration of atrazine in soil was less than the safe concentration,atrazine can stimulate the growth of these crops,whereas the growth would be inhibited when the concentration of atrazine in soil was higher than safety value.更多还原
