| 摘 要： | 以褐土类潮褐土亚类潮垆土土属黑底潮砂泥土土种为研究对象,探讨长期定点不施肥对土壤养分含量及作物产量的影响.结果表明,长期不施肥对土壤有机质、全氮、碱解氮、有效磷、速效钾都有明显的降低,且随年份的推后,降低的幅度越来越大;长期不施肥可使小麦、玉米大幅度减产.

| Abstract: | This paper studied the effects of no fertilization on soil nutrients and crop yield in meadow cinnamon soil in Tangyin County.The result of long-term location test showed that without fertilization the content of soil nutrients declined obviously such as organic matter,total nitrogen,alkalytic N,available P and available K.And as time went on,it declined at more degree.In response to these,the yield of wheat and corn was reduced badly. |
