摘    要:将M3、ASI方法测试土样数据与常规方法测试的数据比较,得出其相关性。其中:磷R(旱田)=0.938779,R(水田)=0.905098;钾R(旱田)=0.865785,R(水田)=0.928413。按照公式将M3方法测试的磷钾数据转换成常规方法数据,并以常规方法评价指标为依据,解决了磷钾数据应用问题。氮的数据经比较没有相关性,可对照土壤有机质、速效氮的分级指标与氮素推荐量,根据目标产量和农户实际用肥量,提出氮的推荐量。

关 键 词:土壤养分  M3、ASI测试方法  数据  比较  相关性  应用

Abstract:Through comparing the soil testing data between M3, ASI method and conventional method, the correlation was obtained that: phosphorus R(dry field)=0.938 779,R(paddy field)=0.905 098;kalium R(dry field)=0.865 785,R(paddy field)=0.928 413. According to the formula, data of phosphorus and potassium by M3 method were converted to that by conventional methods, the conventional method of evaluation index were used as the basis to solve the application problem of phosphorus and potassium data. Nitrogen data also w...
Keywords:soil nutrient  M3 and ASI testing method  data  compare  correlation  application
