| 摘 要： | 通过小麦盆栽试验,研究了玉米秸秆及其秸秆黑炭施加对小麦养分吸收利用和棕壤酶活性的影响。试验设对照(CK),黑炭(B),秸秆还田(S),尿素(U),尿素+黑炭(UB)及尿素+秸秆还田(US)6个处理,各处理3次重复。结果表明:无氮肥施入下,B处理较CK和S处理籽粒产量显著提高99.4%和77.7%,小麦地上部氮、磷、钾吸收累积量分别显著提高94.1%—140.9%,55.4%—66.3%和53.1%—72.6%;有氮肥施入下,UB和US处理较U处理提高籽粒产量8.2%—8.8%,小麦地上部氮、磷、钾吸收累积量分别显著提高14.3%—27.8%,19.6%—30.9%和24.4%—40.9%。秸秆及秸秆黑炭施加处理的氮素利用率显著提高21.4%—41.7%。黑炭施加显著提高土壤中有机碳、NH+4-N、NO-3-N和速效钾含量;在施氮条件下,秸秆还田显著提高土壤中NO-3-N含量;秸秆及黑炭施加对有效磷含量无显著影响。秸秆还田显著提高了土壤脱氢酶、过氧化氢酶、脲酶和中性磷酸酶活性;施加黑炭也明显提高了土壤脱氢酶和脲酶活性,但抑制过氧化氢酶和中性磷酸酶活性。土壤脲酶活性与土壤有机碳、无机氮含量呈显著正相关,表明土壤酶可反映土壤肥力水平。
