摘要
Abstract
The long-term experimental study on forms of inorganic phosphorus in Brown Soil showed that the contents of Ca10－P and O－P in N and check treatment plots decreased gradually，and the content of Ca10－P decreased about 25 percentage，and O－P decreased 11．6～30 percentage 14 years later． The increment in soil inorganic phosphorus caused by fertilization mainly shifted to Fe－P and Al－P． The sencond large proportion shifted from organic fertilization were Ca8－P and Ca2－P． The sequences of the rations of different forms to soil total P changed greatly after 14 years application of organic and phosphatic fertilizer，namely，Fe－P（22．76％）＞O－P（14．6％）＞Al－P（12．49％）＞Ca10－P（9．13％）＞Ca8－P（7．99％）＞Ca2－P（6．58％）． However，in the primary soil，the sequences were observed that O－P（24．21％）＞Ca10－P、Fe－P（17．87％，16．68％）＞Al－P、Ca8－P（1．71％，1．57％）＞Ca2－P（0．23％）．关键词
