| 摘 要： | 以土袋水培法,结合普通盆栽研究水稻黄叶生理病与红壤溶液Fe、Si关系果表明,与无稻红壤溶液相比,植稻红壤的Si/Fe下降而土袋水培Si/Fe升高。电子探针分析显示土培稻根表皮层细胞外壁的Fe峰很高,而土袋水培者的Fe峰很低或为零。讨论了土袋水培的Si/Fe升高的原因及其对消除水稻黄叶生理病的作用。

| Abstract: | Soil - bag hydroponic culture was conducted together with ordinary soil pot experiment to study the relationship between rica oranging physiological disease and Si, Fe in red soil solution. It was found that compared with red soil solution without rice plant, Si/Fe of that with rice plant decreased while Si/Fe of soil-bag hydroponic culture increased. Electron probe analysis showed that the soil pot treated rice root had very high Fe peaks in outer cell wall of epidermis while very low or none Fe peaks were found in soil-bag treated rice root.Thecause for Si/Fe rising of soil - bag treatment and its role on correcting the physiological disease were discussed. |
