| 摘 要： | 为了研究水稻对硅、钾、钙、镁的不同吸收效应，同时探索含钾硅酸盐矿物的肥料价值，本文采用了动力学研究方法．结果表明：水稻对硅、钾、钙、镁的吸收速率因肥料配比差异而不同；而施用多元复合物，水稻生长过程中对硅、钾、钙、镁的吸收速率明显增加；四个动力学方程对水稻吸收养分规律的拟合度都达到了极显著性或显著性水平；单从相关系数及其变异系数来看，四种养分的拟合情况均以Freybdkucg方程为最好．

| Abstract: | This article has studied rice's absorption characteristics of Si, K, Ca and Mg by the dynamics methed.The results are: Rice absorption rate of Si, K, Ca and Mg varied with fertilizer composition;By applying the compound, rice absorption rate of Si, K, Ca and Mg has obviously increased. The imitation coefficient of the four imitating dynamics equations for Si, K, Ca and Mg is in the remarked or extremely remarked level. According to the correlation coeffient and their variation, the imitating of Freundlich equation is the best for all the four nutrition elements. |
