比较了土壤养分状况系统研究法 (ASI法 )测定土壤有效P、K、Zn、Cu、Mn与我国常规化学方法的相关性 ,结果表明ASI法与我国常规化学方法呈显著相关 .盆栽试验进一步验证了ASI方法的土壤磷、钾测定值与作物反应具有良好的相关性
The correlation between soil available P, K, Zn, Cu, Mn and conventional chemical methods in China was compared by systematic study of soil nutrient status (ASI method), and the results showed that ASI method was significantly correlated with conventional chemical methods in our country. The soil phosphorus and potassium values of ASI method have good correlation with crop response
