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,pH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。

Abstract: 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 thatsoil organic mater increasing was the highest and pH 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.

Key words: nutrient, fertility, organic mater, available potassium, nitrate nitrogen, ammonium nitrogen
