| 摘 要： | 采用均匀试验设计法研究pH值和振荡时间对钾钙肥中钾的溶出的影响,并对试验数据进行统计分析得到多元线性回归方程。利用回归方程确定了pH值和振荡时间对钾的溶出的影响,在试验次数较少的情况下结果令人满意。最佳条件为pH=0.00,振荡时间70 m in,钾的最大溶出值为6.33%。

| Abstract: | A study is made of the effect of pH value and oscillation time on the dissolving out of potassium from potassium-calcium fertilizers by the homogeneous experimental design method,and a statistical analysis is made of the experimental data to obtain a multi-variate linear regression equation,which is used to ascertain the effect of pH value and oscillation time on the dissolving out of potassium.A few experiments give satisfactory results.The optimal conditions are:pH=0.00,oscillation time 70 min,and the maximum dissolving out value of potassium 6.33%. |
