| 摘 要： | 对大豆重迎茬的黑土和黑钙土进行养分分析。结果表明，随着连作年限增加，黑土（哈尔滨）全Ｎ、全Ｐ、缓效Ｋ、碱解Ｎ、速效Ｐ、速效Ｋ、有效Ｆｅ、Ｚｎ、Ｍｎ含量以及ｐＨ值都下降，有机质变化不明显；黑钙土（齐齐哈尔）全Ｎ、全Ｐ、缓效Ｋ、碱解Ｎ、速效Ｋ、有机质含量呈增加趋势，而速效Ｐ、有效Ｃｕ、Ｚｎ、Ｆｅ、Ｍｎ含量以及ｐＨ值则呈下降趋势。

| Abstract: | The nutrients in the Black Soils and Chernozemis under
Continuous and Partrition rotation soybean Were anytlsed. The results showed that with the
increase of yeas of continuous cropping, the concentration of total N. total P,none-exchageble
potassiumr, availabele N, avaiable P, available K, available Fe, available Zn, available Mn, pH
dereosed but orgauic matter did not regularly change in Black Soils in Harbin area. Total N,
total P, none-exchageable potarrium, available N available K, organic matter incresed, but
available P, available Cu, available Zn, available Fe, available Mn, pH dereased in
Chernozems in QiqiHer area. |
