| 摘 要： | 利用田间大区对比的方法,2008~2010年在黑龙江省呼兰区黑土上研究玉米机收后秸秆粉碎后直接还田对土壤基本理化性质的影响。结果表明：施用有机物料能够改善土壤的理化性质、培肥地力,与单施无机肥相比,无机肥配施秸秆有机物料能够增加土壤有机质含量,降低土壤容重,提高土壤孔隙度,同时改善土壤的氮、磷、钾养分状况。

| Abstract: | The effect of maize straw chopped and returned to soil on soil basic physical and chemical properties was conducted by the method of block compared from 2008 to 2010 in Hulan black soil.The results showed that soil basic physicochemical properties and fertilizing soil fertility were improved by using organic fertilizer compared with inorganic fertilizer only.If using them together,soil organic matter was improved,soil bulk density was decreased,soil porosity was improved.At the same time,nitrogen,phosphorus,potassium of soil nutrient status were improved. |
