本文采集肥东三个乡镇180个土样来以录求ASI法与我国常规分析方法测定P、K的相关性。试验研究结果表明,两种方法测定测定三个乡镇土样土壤中的有效磷、钾具有显著正相关,其相关性方程、相关系数分别如下:张集乡P、K分别为Y=0.5319x+4.8349,R=0.8049、Y=0.9321x+9.1538,R=0.8678;众兴乡P、K分别为Y=0.8117x-0.4314,R=0.8303,Y=0.816x+18.241,R=0.8283;路口乡P、K分别为Y=0.6899x+2.565,R=0.8947,Y=0.8705x+9.4885 R=0.8583。
This paper collected 180 soil samples from three townships in Feidong to record the correlation between P and K using ASI method and our routine analysis method. The experimental results show that there are significant positive correlations between the two methods for the determination of available P and K in the soil of three townships. The correlation equations and correlation coefficients are as follows: P and K of Zhangji Township are Y = 0.5319x + 4.8349, R = 0.8049, Y = 0.9321x + 9.1538, R = 0.8678; Zhongxing Township P and K respectively Y = 0.8117x-0.4314, R = 0.8303, Y = 0.816x + 18.241, R = 0.8283; , K are Y = 0.6899x + 2.565, R = 0.8947, Y = 0.8705x + 9.4885 R = 0.8583, respectively.
