摘要：依托2002—2009年开履的蔬案田间试验结果，土样分别用Olsen法，Mehlich1法，Mehlich3法和ASI法测定其有效磷含量，建立上述测试方法的案田土壤磷象丰缺指标，并进行不同测试方法的相关研究。以巅案产量<%6%606%06% 对应的土境有效磷卡缺指标0lsen=P为<23、23~59,59～81和>81mg/kg;M1-P为<19、19~102、102～179 和>179 mg/kg; M3P为<19,19 ~96,96~165 和>165 mg/kg; ASIP为<22,22 ~68,68 ~98 和>98 mg/kg。
Olsen法、M3法、M1法和ASI法4种方法，两两的相关性均达到极显著水平。关键词：蔬菜；相对产量；有效确；丰缺指标

Abstract: Based on the results of field experiments on vegetable conducted during the year 2002 2009, the abun-dance and deficiency indices of soil available phosphorus was investigated. The different soakage methods of soil available phosphorus were also discussed. Soil available phosphorus were classified into four classes (low, medi-%ae 90% , 90%-95% and > 90% relative yield). The abundance and deficiency indices were simulated by the log arithm models. The results indicates that available phosphorus indices for different soakage methods are Olsen-P < 23, 23 59, 59 81 and >81 mg/kg; Mehlich1-P <19, 19102, 102 179 and >179 mg/kg; Mehlich3 P < 19, 19 96, 96 165 and >165 mg/kg; ASI-P <22, 22 68, 68 98 and >98 mg/L, corresponding to differ ent class of soil available phosphorus. There were significant correlation between the results obtained from Olsen, Mehlich 3, Mechlich 1 and ASI methods.
