ＨＣｌ浸提法检测水稻土有效磷的研究何新桃（三明市农业中心化验站３６５０００）提取测定土壤有效磷的方法很多。ＨＣｌ提取法是其中之一。李庆逵等（１９５３），叶德盛（１９５７），孙羲等都研究不同浓度ＨＣｌ提取酸性土壤有效磷；１９８０年福建土壤普查，也用此法...
Determination of available phosphorus in paddy soils by HCl extraction He Xintao (Sanming Agriculture Center Laboratory 365000) There are many ways to extract available phosphorus from soils. HCl extraction is one of them. Li Qingxuan et al. (1953), Ye Dasheng (1957), Sun Xi et al. Studied different concentrations of HCl to extract available phosphorus in acidic soil.
