| 摘 要： | 土壤有机质和盐基饱和度是评价土壤肥力的重要指标。为了探究土壤调理剂与配施化肥对热带地区酸化土壤有机质和土壤交换性能的影响,明确土壤调理剂配施配方肥改良酸性土壤和提升土壤肥力的最佳方案,本研究在海南省儋州市木薯园开展田间试验,采用有机无机复合型土壤调理剂并配施不同梯度配方肥的改良方式,对比分析不施肥、常规施肥和土壤调理剂与化肥配施对木薯地土壤有机质和土壤交换性能的影响,从而为改良酸性土壤、减肥增效、缓解土壤环境等问题提供理论依据和科学参考。结果表明：与CK（不施肥）相比,土壤调理剂配施配方肥（100%、75%、50%）处理的pH分别提高了0.29、0.24和0.44（P<0.05）,土壤有机质分别提高了20.82%、22.04%和20.49%（P<0.05）,交换性盐基总量分别提高了20.62%、21.25%和48.75%（P<0.05）,土壤交换性酸含量分别降低了17.65%、15.38%和30.43%（P<0.05）,在所有处理中以Tr50（土壤调理剂+50%配方肥）处理的改良效果最好。因此,在土壤改良中推荐施用土壤调理剂+50%配方肥的改良方案。

| Abstract: | The saturation of soil organic matter and salt base serves as an important indicator for evaluating soil fertility, so this study is to explore the effects of soil conditioners and directive fertilizers on acidified soil, organic matter and soil exchange performance in tropical areas, clarify the formula of soil conditioners and directive fertilization, improve acidic soil and improve soil fertility. The cassava orchard in Danzhou City, Hainan province was applied to carry out field experiments. Organic-inorganic composite soil conditioners were used, and different gradient formula fertilizers were applied. The research aims to compare and analyze the effects of no fertilizer application, conventional fertilizer application and application of soil conditioner and chemical fertilizer on soil organic matter and soil exchange properties of cassava land, so as to provide a theoretical basis and scientific reference for improving acidic soil, increasing soil fertility and mitigating soil environment. The experimental results showed that compared with CK, the soil conditioner with directive fertilization (100%, 75%, 50%) treatment increased pH by 0.29, 0.24 and 0.44 (P<0.05), the soil organic matter by 20.82%, 22.04% and 20.49% (P<0.05), the total exchangeable salt base by 20.62%, 21.25% and 48.75% (P<0.05), and soil exchangeable acid content decreased by 17.65%, 15.38% and 30.43% (P<0.05), respectively, and of all treatments, Tr50 (soil conditioner+50% formulated fertilizer)treatment had the best effect of improvement. Thus, the improvement scheme of applying soil conditioner+50% formulated fertilizer in soil improvement was recommended. |
