摘要： 本试验通过大剂量液氯、四种消毒剂对玉米苗期根系活力的影响试验，得出结论：大剂量液氯对玉米根系具有毒害作用，显著降低根活性，小剂量液氯、二氧化氯、二氧化氯与液氯混合则对玉米根活性无明显影响，对根系活力有一些影响；液氯作消毒剂的最适投入量为8 mg/l，二氧化氯作消毒剂的最适投入量为6 mg/l，二氧化氯与液氯混合作消毒剂的最适投入量为（4＋2）mg/l。

Abstract: The Paper will discuss influence of liquid chlorine and chlorine dioxide and mixture of both on livingness of Maize root population. The result of experiment show that liquid chlorine in great does poisoned root, and reduced obviously activity of roots. Other disinfectors have no effect on activity of roots, but affect livingness of Maize Root-population. And the right dose of liquid chlorine is 8mg/l，the right dose of chlorine dioxide is 6mg/l, the right dose of mixture is （4＋2）mg/l.
