| 摘 要： | 在内蒙古呼伦贝尔盟农区代表性土壤上，选择连作１ ～５ 年大豆田采土样化验分析，结果表明：随着大豆连作年限的增加，土壤ＰＨ 值降低；土壤中全氮和碱解氮含量有所增加；速效磷、速效钾在新开垦甸子地变化不大，而在坡地表现显著降低；钼、锌含量表现降低，导致大豆产量逐年下降

| Abstract: | Soil of soybean cropland that continuous cropping 1-5 years was analyzed in Hulunbeier league of Inner Mongolia. The result showed: with the continuous cropping years of soybean going up, the PH value of soil is coming down; the content of all N and alkaline N is rising, the container of quick-acting Pand K is no change in level land , but it is reduced in sloping fieds; the content of Mo and Zn is decline . All these will result in the yield of soybean to reduce years by years. |
