应用“A”值法测定了水稻生育期吸磷动态、土壤有效磷含量、土壤潜在磷的利用系数、水稻植株中磷素的p肥/p土比以及磷肥利用率等项指标对吉林省分布较广的白浆土、冲积土、草甸土3种土类8种水田土壤的供磷水平作出了评价。从土壤有效磷含量看,草甸土较高,冲积土居中,白浆土较低。从土壤磷素的供应能力看,草甸土较强,冲积土次之,白浆土较弱。从磷肥利用率看,冲积土较高,白浆土居中,草甸土较低。 The “A” value method was used to determine the dynamic changes of phosphorus uptake during the growth period of rice, the available phosphorus content of soil, the potential phosphorus utilization coefficient of soil, the ratio of phosphorus to total phosphorus and p fertilizer, Phosphorus levels in soils of 8 paddy soils of broad white soil, alluvial soil and meadow soil were evaluated. From the soil available P content, meadow soil is higher, alluvial soil middle, white soil lower. From the perspective of the supply capacity of soil phosphorus, the meadow soil is stronger, the alluvial soil is second, and the white soil is weaker. From the perspective of utilization of phosphate fertilizer, alluvial soil is higher, albacore soil and meadow soil are lower.
