| 摘 要： | 研究了牛粪、沼渣、污泥、鸡粪、菌渣和猪粪6种有机物料施用对灌漠土春小麦产量和土壤肥力的影响，旨在考察6种有机废弃物农用的可行性。采用大田试验方法，分别将6种有机物料与70%常量化肥配合施用，共设置了8个处理。结果表明，与对照相比，6种有机物料与70%常量化肥配合施用均能提高春小麦的籽粒产量和生物产量。与施用常量化肥的处理相比，菌渣、污泥和鸡粪处理能提高春小麦的氮素利用率；菌渣、沼渣和污泥处理能提高春小麦的磷素利用率。菌渣和污泥处理的钾素利用率要远远高于其他有机物料的处理，分别达到了97.47%和94.75%。不同有机物料输入均能显著提高灌漠土的有机质含量，对土壤全量养分含量的影响均表现不显著，对速效养分含量则能产生不同的影响。

| Abstract: | Effects of application of 6 different organic materials such as cattle manure, biogas residue, sewagesludge, chicken manure, mushroom residue and pig manure on spring wheat yield and soil fertility of irrigateddesert soil were studied in order to investigate the agricultural feasibility of organic wastes. The study wascarried out through field experiments, in which combined application of 6 different organic materials and 70%conventional chemical fertilizer was adopted, with 8 treatments set up in total. The results showed thatcombined application of 6 different organic materials and 70% conventional chemical fertilizer could increasethe grain yield and biological yield of spring wheat in comparison to control. Mushroom residue, sewage sludgeand chicken manure could increase N use efficiency and mushroom residue, biogas residue and sewage sludgecould increase P use efficiency of spring wheat by contrast with conventional chemical fertilizer application.The K use efficiency of mushroom residue and sewage sludge was found to be much higher than othertreatments, reaching 97.47% and 94.75% respectively. The input of different organic materials increased theorganic matter content of irrigated desert soil, without having significant influences on soil total nutrientcontent, but having different influences on soil availablenutrient content. |
