- 采用Bowman和Cole提出的有机P分组方法,对长期施肥条件下土壤有机P的组成变化以及有机P及其组分与有机质、速效P的关系进行研究。Variation of soil organic phosphorus fractions, and relationship of organic P and its fractions, with soil organic matter and readily available P were studied with Bowman-Cole method.
- 土壤速效P出现富集的转折点因供试土壤而异,第三纪红壤性水稻土大致为P2O560~120mg/kg,而第四纪红壤性水稻土和黄泥土为P2O5120~180mg/kg。The enriching point of available P depended on soil types, being P2O5 60 ~ 120 mg/kg in the paddy soil derived from Tertiary red sandstone, and P2O5 120 ~ 180 mg/kg in the paddy soils from Quaternary red clay and loess-like lake sediment.
