| 摘 要： | 研究了不同开垦年限黑土磷素的形态、数量的变化,结果表明:开垦后黑土全磷含量无明显规律性变化,但土壤有效磷数量显著上升,在土壤磷的组分上,土壤有机磷数量显著下降,而土壤无机磷明显升高。在土壤无机磷的6个组分中,Fe-P、O-P占比例最大;其次Al-P、Ca10-P;再次Ca2-P、Ca8-P。垦后无机磷6个组分含量都有升高,绝对升高量顺序为Fe-P>Al-P>Ca2-P>O-P>Ca10-P>Ca8-P。上升强度顺序为Ca2-P>Al-P>Ca8-P>Ca10-P、Fe-P>O-P.

Changes of Phosphorus Content and Forms in the Black Soil with Different Reclamation |
| |
| Abstract: | The change of form and content of black soil Phosphorus is researched under reclamation. The results showed: After black soil being exploited, the change of its total P content was not in one direction,but the amount of available P markedly increased. Organic P content markedly decreased, whereas, inorganic P content increased after reclamation. The amount of six components of inorganic P increased after reclamation. Their amount increased according to following:Fe-P>Al-P>Ca2-P>O-P>Ca10-P>Ca8-P,and their intensity increased according to following:Ca2-P>Al-P>Ca8-P>Ca10-P>Fe-P>O-P. |
