摘要： [目的]研究2种含氯甲基吡啶硝化抑制剂在滴灌条件下对土壤氮素转化及棉花产量的影响.[方法]在石河子农科中心设置硝化抑制剂棉花滴灌小区试验.[结果]供试的2种硝化抑制剂随水滴施第6 d后均表现显著的硝化抑制效果,土壤NH4+-N较对照增加3.82;～211.25;,NO3--N降低56.2;～77.12;;表观硝化率较对照处理降低2.66～52.83个百分点;提高氮肥利用率1.54～4.15个百分点;1 hm2增产籽棉202.5～247.5 kg,增产幅度3.43;～4.3;,新增经济效益1 059～1 306.5元.[结论]滴灌条件下硝化抑制剂随水滴施,简单易行,能够有效改善棉株的氮素营养水平,增产效果显著.
