摘　　要：为快速培肥新增耕地土体,提高新增耕地土壤养分水平,保障作物生长发育和粮食生产,通过在有机重构土体上施用不同肥料,组成肥效试验,探究不同肥料配比对土体养分含量及水稻产量的影响。结果表明,施用商品有机肥土体有机质含量增加量最大,p H最低,更利于水稻生长;尿素+过磷酸钙+氯化钾+商品有机肥配施土体硝铵态氮含量最高,有利于速效氮的培肥,对新增耕地的培肥效果最佳;施用氯化钾处理土体速效钾含量高于施用硫酸钾处理。In the purpose of rapidly increasing soil nutrient concentration and rapid fertilization of newly-increased cultivated land. And ensure crop growth and food production. Different fertilizers were put into soil to form a fertilizer test and the effect on soil nutrient concentration were analyzed. The result showed that ： soil organic mater increasing was the highest and p H was lowest with commercial organic fertilizer input. It is better for rice growth. Soil nitrate nitrogen and ammonium nitrogen was the highest with urea＋superphosphate＋muriate＋commercial organic fertilizer input. It is good for increasing available N concentration. The urea＋superphosphate＋muriate＋commercial organic fertilizer treatment was the best for new arable land fertilizer. Available potassium was higher in muriate input treatment than in potassium sulphate treatment.
