| 摘 要： | 通过对临朐县2007—2009年冬小麦"3414"田间肥效对比试验数据进行统计分析,得出作物相对产量与土壤有效养分存在的对数函数关系,且相关方程显著,相关系数较高,证明缩小区域建立指标体系增加了方程的可靠性和可行性;通过相关方程将土壤养分分为高、中、低3个级别,建立了该县土壤碱解氮、有效磷、速效钾的丰缺指标体系。

| Abstract: | Analyzing the data of 3414fertilizer experiments in winter wheat from 2007 to 2009 in Linqu,the presence of logarithmic function between crop yield and soil nutrients was got.The related equation was significant and had higher correlation coefficient.It proved that narrow region to confidence index system increased the reliability and feasibility of the equation.Through the relevant equations,the soil nutrient was divided into high,medium and low level.Then the abundance and deficiency index in soil such as... |
