摘　　要：对山西省晋中、忻州、吕梁、运城、晋城、长治等地市不同肥力水平 0～ 2 0cm的 1 0 0个土样 ,分别采用常规分析与速测法 (目测 )对各土样中速效磷 ,速效钾进行测定 ,以探索速测与常规分析法测定值间的相关性。通过回归分析对数据的处理、统计分析 ,表明两种方法测定值间相关性显著 ,并建立了它们之间的线性转换模式 (1 )、(2 )。 (本模式适用于石灰性土壤 )In this paper, 100 soil samples with different fertility (0～200m)are obtained from Jinzhong, Xinzhou, Luliang, Yuncheng, Jincheng and Changzhi.The quick\|acting phosphorus (P) and potassium (K) in the soil samples are measured with the conventional and the quick estimation methods respectively in order to find out the relation between the measurement values. By means of regression analysis, the result shows that there exists great correlation between them. As a result, the linear trans for mation patterns \*(1) and (2)\# between them are established. (The patterns are applicable to calcareous soil )
