研究了作保灵对水稻的保护作用及对氯嘧磺隆的解毒机理。当土壤中氯嘧磺隆残留量为 10μg· kg-1时 ,水稻生长发育受到影响 ,并随着氯嘧磺隆残留量的增加 ,对水稻的抑制作用明显增强。作保灵 50 mg· kg-1浸种或 2 0 0 mg· kg-1叶喷都能缓解氯嘧磺隆对水稻产生的药害。作保灵能明显提高水稻体内谷胱甘肽转移酶 (GST)活性 ,增加谷胱甘肽 (GSH)、多酚及脯氨酸含量 ,诱导氯嘧磺隆与谷胱甘肽、多酚进行轭合 ,从而对氯嘧磺隆进行解毒。 The protective effect of Pauling on rice and the detoxification mechanism of chlorimuron-ethyl were studied. When the residual amount of chlorimuron-ethyl in the soil was 10 μg · kg-1, the growth and development of rice were affected. With the increase of chlorimuron-ethyl residues, the inhibitory effect on rice was obviously enhanced. To protect the 50 mg · kg-1 soaking seed or 200 mg · kg-1 leaf spray can alleviate the toxicity of chlorimuron-ethyl to rice. Pauli can significantly increase the activity of glutathione transferase (GST) in rice, increase the content of glutathione (GSH), polyphenol and proline, and induce the induction of chlorimuron and glutathione, polyphenols Conjugate, thereby detoxification of chlorimuron-ethyl.
