| 摘 要： | 采用修改后的张守敬-Jackson法在50 d的培养过程中对施磷黄棕壤和红壤中的无机磷组分进行跟踪测定。结果表明:施用无机磷肥能全面提高土壤各无机磷组分含量,但对不同土壤中各无机磷组分间的转化影响不一。磷在黄棕壤中首先转化为水溶性磷和松结合态磷(S-P)、铝结合态磷(A l-P)和钙结合态磷(C a-P),然后S-P和C a-P继续向A l-P转化,施磷对黄棕壤中闭蓄态磷(O-P)和铁结合态磷(F e-P)含量无明显影响;在红壤中,施用的磷首先转化为S-P、A l-P和F e-P,然后S-P、A l-P继续向F e-P转化,施磷对红壤中O-P和C a-P的含量也无明显影响。

| Abstract: | Yellow brown soil and red soil,which were applied inorganic phosphorus(Pi) fertilizer and then cultured under the moist condition in the room for 50 days,were sampled and contents of Pi fractions were determined with Jackson-Chang's method.The results indicated that phosphorus fertilizer increased the contents of all Pi fractions in soils.On yellow brown soil the fertilized phosphorus was firstly transformed into S-P,Ca-P and Al-P,and then S-P and Ca-P converted to Al-P mainly.However,it didn't obviously influence the contents of O-P and Fe-P in this soil.For red soil the fertilized phosphorus was at first combined in S-P,Al-P and Fe-P,after that the S-P and Al-P were gradually transformed into Fe-P. Phosphorus fertilizer didn't obviously increase the contents of O-P and Ca-P in red soil. |
