摘    要:长期定位试验结果表明,地力贡献具有各异性、持续性、相关性和稳定性四个特点。在水稻生产中,应充分重视土壤肥力的培育和提高,才能提高肥料施用效益。根据作物肥料效应大小,水稻施肥应氮钾肥配合施用,旱作则要氮磷肥配合施用。

关 键 词:地力贡献,长期定位试验,合理施肥

Abstract:The results of long--term experiments inchoated that contribution of paddy soil fertility to crop yield had the characteristic of variance, perpetuity, relativity and stability, In rice production, It shoull be closely emphasised to maintain and increas the soil fertility to increase the efficiency of fertilizer application. A wording to the crop response of fertilizers,We rewmended that combined applications of NK nutrients in rece. and NP nutrients in upland crops be put into practice.
Keywords:Contribution of soil fertilizer to crop yield  Long-term experiment  Optimum fertilization
