【摘要】 通过对我国北方枣麦间作区土壤物理性质、化学性质、微生物学特性等的分析研究 ,结果表明 :枣麦间作这一种植方式可促进土壤团粒结构的形成和孔性的改善 ,并可增加土壤有机质和氮素含量 ,促进各类微生物菌群的增殖 ,提高土壤的生物活性强度 ,是北方冬小麦产区适宜推广的一种用地养地相结合的立体种植方式。更多还原

【Abstract】 The physical,chemical and microbiological properties of soil in the field with the intercropping of chinese date and winter wheat were studied.The results showed that this cropping system promote the growing of soil granular structure and better soil property, increased soil organic matter and nitrogen, promoted the proliferation of all kinds of soil microbe, and improved soil biology activity. It could be concluded that this cropping system is a three-dimension-planting which can enrich soil to some degree, so it can be popularized wildly for winter wheat districts in North China.更多还原
