- 采用Bowman和Cole提出的有機P分組方法,對長(cháng)期施肥條件下土壤有機P的組成變化以及有機P及其組分與有機質(zhì)、速效P的關(guān)系進(jìn)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出現富集的轉折點(diǎn)因供試土壤而異,第三紀紅壤性水稻土大致為P2O560~120mg/kg,而第四紀紅壤性水稻土和黃泥土為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.
