| 摘 要： | 水稻盆栽试验结果表明，施用ＣａＯ２、ＭｇＯ２和ＢａＯ２三种过氧化物（释氧物）能在一定时间范围内提高土壤Ｅｈ值．在土壤中添加Ｆｅ（２＋）和葡萄糖来模拟潜育性土壤的强还原条件，施用过氧化物能明显降低土壤还原物质总量和活性还原物质含量，减轻Ｆｅ（２＋）等还原物质对水稻的毒害，促进水稻的正常生长发育，提高产量。

| Abstract: | Rice pot trial was conducted and showed that addition of CaO2, MgO2 and BaO2 which can gradually release oxygen could raise soil Eh within a definite period.Strong reduction condition of gleyed paddy soil was simulated by adding Fe(2+) and glucose into soil. Under this simulated reduction condition, the addition of above three oxygen-releasing peroxides could markedly reduce both the content of total reduction matter and the content of active reduction matter, and alleviate the toxity of Fe(2+) and other reduction matter to rice plant. Therefore, the rice plant grows better and its grain yeild get raised, compared with the control. |
