| 摘 要： | 为探索不同土壤改良剂产品对酸性土壤的改良及增产效果,在平乐县有机质提升酸性土壤改良项目区,使用石灰、石灰石粉、商用土壤调理剂进行土壤改良效果对比试验。结果表明:在酸性稻田施用石灰、石灰石粉,商用土壤调理剂1号、商用土壤调理剂2号,能提高土壤有机质2-5 g/kg、土壤pH值0.1-0.2,可作为土壤改良剂产品进行酸性土壤改良;在酸性稻田应用测土配方施肥的基础上,施用石灰、石灰石粉、商用土壤调理剂1号、商用土壤调理剂2号,均可提高水稻产量10%左右,以商用土壤调理剂1号效果最好。

| Abstract: | In order to explore the improvement and yield - increase effect of different soil amelioration a- gents （lime, limestone powder, commercial soil amelioration agent） to acid soil, at the Project area of Pingle County, a comparison experiment was conducted and the the results showed that the application of lime, limestone powder, Agent 1 and Agent 2 in acid paddy field could increase soil organic matter by 2 - 5 g/kg, pH value by 0.1 - 0.2, which means these amelioration materials can be the agents for acid soil improvement. Moreover, the fertilization of N, P, K in acid paddy field and the application of amel- ioration materials can also increase the rice yield by about 10%. Geneal speaking, the Agent 2 will have the best integrated effect |
