本文以~(32)P示踪法测得的“A”值与盆栽试验水稻吸磷量为标准参比项,用6种化学提取法对吉林省3种酸性土壤的磷素形态进行研究。结果表明,Al—Abbas法与“A”值和水稻吸磷量分别达极显著相关与显著相关,与供给水稻磷素的主要磷源磷酸铁星极显著相关。建议在吉林省酸性水稻土上速效磷的化学提取法应采用Al—Abbas法。 In this paper, the “A” value measured by ~ (32) P tracer method was used as the standard reference for phosphorus uptake by pot experiment, and the phosphorus forms of three acid soils in Jilin Province were studied by six chemical extraction methods. The results showed that there was a significant and significant correlation between the Al-Abbas method and the “A” value and the phosphorus uptake by rice, which was significantly correlated with the iron phosphate star phosphate, which was the main source of phosphorus supply for rice. It is suggested that Al-Abbas method should be used for the chemical extraction of available phosphorus in acidic paddy soils in Jilin Province.
