摘要
为探究不同生物质材料对蕉园土壤有机质及组成的影响,以木炭、椰壳炭、椰糠炭和与椰糠炭等碳量的椰糠为材料,分别以质量分数为2%和4%的用量加入土壤中,于室内常温培养并保持土壤含水量不变。在第15、30、60、90、120和180 d采集土壤,分析不同生物质材料对土壤有机质、胡敏酸、富里酸和土壤胡敏酸/富里酸的影响。结果表明:添加木炭、椰壳炭、椰糠炭和椰糠均能提高土壤有机质含量,并随添加量的增加而升高;添加木炭、椰壳炭、椰糠炭和椰糠均能加速土壤有机质的分解,添加椰壳炭对土壤有机质分解的影响相对较小。椰糠的添加主要是同时增加了土壤胡敏酸和富里酸碳含量,生物炭(木炭、椰壳炭和椰糠炭)的添加主要是影响了土壤胡敏酸与富里酸的相互转化。
        In order to explore the effect of different biomass materials on the content and composition of organic matter in the soil of planting banana trees,in this study,charcoal,coconut shell charcoal,coconut bran charcoal and coconut bran with carbon content equal to coconut bran charcoal were used as the research materials,biomass materials were added to air-dried soil at rates of 2% and 4%(w/w)separately,then cultured them at room temperature and maintained soil moisture content. Soil organic matter content,humic acid carbon content and fulvic acid carbon content were tested after 15,30,60,90,120 and 180 days culture.The results showed that adding charcoal,coconut shell charcoal,coconut bran charcoal and coconut bran improved soil organic matter content and the effect increased with the increase of adding quantity.The decomposition of soil organic matter was accelerated by adding charcoal,coconut shell charcoal,coconut bran charcoal and coconut bran,but the effect of coconut charcoal was relatively small.Adding the coconut bran mainly increased the soil humic acid and fulvic acid carbon content at the same time,adding biochar(charcoal,coconut shell charcoal and coconut bran charcoal)mainly affected the conversion of soil humic acid and fulvic acid reciprocally.
