摘要： 为研究秸秆还田条件下小麦氮肥施用方法及秸秆还田调控氮肥对小麦产量及土壤钾形态的影响，通过田间试验，研究了秸秆全量还田条件下氮肥不同基追比调控对小麦产量、土壤不同形态钾含量的影响。结果表明，秸秆还田条件下，氮肥基追比7:3、6:4处理的小麦产量最高。从土壤不同形态钾含量来看，氮肥基追比7:3、6:4处理的土壤水溶性钾、交换性钾、全钾含量最高。所有处理的非交换性钾差异不大。在本试验条件下，氮肥基追比7:3、6:4处理为秸秆全量还田下效果最佳，利于小麦产量提高及增加土壤速效钾及全钾含量。

Abstract: In order to study the effects of nitrogen fertilizer regulation with straw-return on wheat yield and potassium forms, field experiment was arranged in Pinyuan County. The results indicated that, nitrogen fertilizer regulation with straw-return could affect the wheat yield and potassium forms. The highest yield of wheat was obtained with nitrogen dressing ratio 7:3 and 6:4. As to the potassium forms, the content of water-soluble potassium, exchangeable potassium and total potassium were the highest with nitrogen dressing ratio 7:3 and 6:4, and the difference of non-exchangeable potassium were not significant among all treatments. Under the experiment condition, nitrogen dressing ratio 7:3 and 6:4 were the best treatments, they could increase the wheat yield and soil total potassium and available potassium content.
