了解果园内速效磷的供应状况,对于施肥有着直接的指导意义。而土壤速效磷的测定与浸提剂的种类、水土比、浸提时间、浸提温度密切相关,处理方法不当测定结果将会对土壤速效磷状况作出错误评价。

Soil available phosphorus is closely related to the type of extractant, soil-water ratio, extraction time and extraction temperature. The improper treatment method will make a wrong assessment of soil available phosphorus status.
