| 摘 要： | 采用砂滤管法研究了有机物料对土壤有机质的影响．结果表明，爬地兰、无刺含羞草、日本草、百喜草和宽叶雀稗地上和地下部物料的腐殖化系数分别为０．３２－０．３８和０．３４－０．４３．各物料均能显著提高土壤有机碳含量，增加的土壤有机碳地上部物料平均７７．５％、地下部物料平均６８．１％以有机无机复合状态存在．加入有机物料还能增加松、紧结合态腐殖质量，提高松紧比和增加松结态的胡敏酸和富里酸量．

| Abstract: | Incubation experiment was carried out to study the effect of plant materials on the soil organic matter. The results showed that humification coefficients of the roots and above ground parts of Indigofera ennecaphylla, Mimosa invica, Paspalum wettsteinii, P. notatum flugge and Borreria latisolia were 0.34-0.43 and 0.32-0.38, respectively. Incorporation of plant materials tested could raise soil organic carbon significantly.And 68.1% and 77.5% of the newly formed humus derived from roots and the above ground parts was found in the heavy fraction respectively. Organic materials could increase the contents of loosely and tightly combined humus,the ratios of loosely to tightly combined humus as well as the contents of humic acid and fulvic acid. |
