| 摘 要： | 采用蒋柏藩-顾益初无机磷分级方法,对黄土高原两种农田土壤剖面(0～100 cm)中无机磷形态分布特征进行了研究.结果表明:两种农田土壤剖面(0～100 cm)中无机磷形态占全磷的90.95%;无机磷又以Ca-P为主,所占比例在87.86%～92.55%之间;糜子地土壤剖面中无机磷总量、Ca2-P、Ca8-P、Al-P和...

| Abstract: | By using the Jiang-Gu inorganic phosphorus fractionation method,a study was conducted on the forms and compositions of inorganic phosphorus in 0~100 cm layers of calcareous soil profile on sloping land of two kinds of farmland soil on the Loess Plateau.The results showed that inorganic P was 90.95% of total P.Ca-P was in a dominate position in inorganic P,its proportion was 87.86%~92.55%.The contents of inorganic P,Ca2-P,Ca8-P,Al-P and Fe-P in soils of Panicum miliaceum L were higher than that in soils of S... |
