摘要
根据"3414"试验结果,初步摸清了水稻相对产量与土壤有效养分,土地依存率与土壤有效养分之间的关系,以及测土值与水稻养分吸收关系,并根据有效养分含量与校正系数的函数关系,建立了水稻土壤有效养分校正系数推算表。
Basted on the results of ＂3414＂test,the relationship between rice relative yield and soil available nutrient,land dependence rate and soil available nutrient,and soil testing value and rice nutrient uptake were primarily known.The calculating table on the correction coefficient of paddy soil available nutrient was established according to the functional relationship between the available nutrient content and correction coefficient.
