摘要
经过１９９２～１９９５年四年对宾县坡耕地薄层黑土中低产田进行定位培肥研究。结果表明，采取改垄向、带状间作、机械灭茬、增施农肥、配方施用化肥等综合培肥措施后，土壤有机质净积累０．０２３％，全氮净积累０．０８７％。土壤容重降低了０．２３ｇ／ｃｍ３，田间持水量增加了８．４％，明显地促进土壤速效养分的释放，改善土壤的物理性状，作物产量较对照增加１８％左右。
We studied on the sloping fields of thin layer black soil at fixed positions for four years. The results Showed that soil organic matter increased 0.023% after the synthetical amelioration method was used to it. The total N increased 0.087%. Soil bulk density decreased by 0.23/cm 3. Field miosture capacity increased 8.4%. Crop yield increased about 18.0% compared with the CK.
