Phosphorus forms in tobacco-planting soils with different parent soil materials in Hunan Province
摘要
Abstract
In order to investigate the phosphorus status in tobacco-planting soils with different parent soil materials in Hunan Province, inorganic and organic phosphorus in 16 representative soils with four main parent materials in Hunan tobacco-planting areas were analyzed. The results showed that: 1) The major component in soil inorganic phosphorus was O-P (Closed-storage phosphorus), which accounted for 43.04%-54.29% of total inorganic phosphorus content. The content of Al-P (Aluminum phosphate) was the lowest. The contents of Fe-P (Iron phosphate) and Ca-P (Calcium phosphate) in tobacco-planting soils with different parent materials differed greatly. The ratios of different components in inorganic phosphorus in purple slate and slate were in the order of O-P>Ca-P > Fe-P >Al-P, and their ranks were O-P>Fe-P>Ca-P>Al-P in quaternary laterite and limestone. In the Ca-P components, Ca10-P content accounted for 54.32%-64.61% of the total Ca-P. 2) The major component in soil organic phosphorus was moderately labile organic phosphorus, which accounted for 51.72%-71.16% of the total organic phosphorus content. Generally, the contents and proportions of different organic phosphorus in tobacco-planting soils with different parent materials were in the order of moderately labile organic phosphorus > highly resistant organic phosphorus > moderate resistant organic phosphorus and labile organic phosphorus.关键词
