【摘要】 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 8mg l,二氧化氯作消毒剂的最适投入量为 6mg 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。更多还原

【Abstract】 Th e Paper will discuss influence of liquid chlorine and chlorine dioxide and mixtu re of both on livingnessof Maize root population The result of experim e nt show that liquid chlorine in great does poisoned root, and reduced obviously activityof roots Other disinfectors have no effecton activity of roots, but affect livingnessof maize root-population And the r ight dose of liquid chlorine is 8 mg/l,the right dose of chlorine dioxide is 6 mg /l, the right dose of mixture is(4+2)mg/l更多还原
