摘  要:
以土壤有效磷含量为考察指标,用钼锑抗比色法(DB 21-601-91)测定了辽宁省风沙地改良利用研究所章古台试验基地风沙土有效磷含量,测定值能较好地反映作物需磷状况。结果表明,章古台风沙土有效磷平均含量仅为6.48 mg/kg。针对辽西北风沙土缺磷的问题,合理施用磷肥和土壤改良势在必行。该试验方法简便、灵敏,结果稳定、准确、可靠,适用于土壤中有效磷含量的测定。

摘  要:
The content of available phosphorus was determined with Mo-Sb colorimetry(DB 21-601-91) in Zhanggutai sandy soil test base of Liaoning institute of sandy land improvement and utilization.The results showed that the average content of available phosphorus in Zhanggutai sandy soil base was only 6.48 mg/kg.The problem of phosphorus deficiency was serious in sandy soil of Northwestern Liaoning.Rational application of fertilizer and soil improvement was imperative.The method was simple,sensitive,accurate and reliable,which could be applicable to determine soil content of available phosphorus.
