摘要:
通过布设在长武生态站的长期小麦试验连作发现，施用有机肥以及有机肥与化肥配施能明显提高土壤肥力，化肥单施提高土壤肥力不明显。施用有机肥能明显地增加有机氮中AN-N和HUN-N含量，对NH3-N和ASN-N不明显。从农业生产成本考虑，应当充分利用农村当地资源，增施有机肥，合理施用化肥和合理轮作的管理措施，促进农业的可持续发展。
Abstract:
Applying organic manure or mixture of organic manure and fertilizer can obviously improve soil fertility, but only applying fertilizer cannot do through long term continuous wheat in Changwu ecological station.Organic manure can obviously increase contents of AN-N and HUN-N.From the view of agro production cost, enough using agricultural resources, applying organic manure, rational application of fertilizer and rationally rotation can promote sustainable agricultural development.
