| 摘 要： | 采用长期定位研究方法,探讨了不同耕作处理对白浆土有机质及其品质的影响。结果表明,长期采用免耕处理有利于白浆土有机质的积累,并以增加稳结态和紧结态腐殖质含量为主,松/紧比值下降较大,Kos值增加;长期采用深松和普翻处理土壤中,有机质含量下降,但Kos值增加幅度小于免耕,松/紧比值增加;不同耕法对土壤FA、HA及HA/FA比值影响较小。

| Abstract: | By using the method of long-term stationary experiment,the effects of different culture on organic matters and their qualities in albic soil were studied.The results show that long-term non-tillage was more beneficial to accumulate organic matters in the albic soil, and increased mainly stable and tight combining humus, but loose/tight value descended more, and Kos value increased.In long-term ploughing and subsoiling treatments, the organic matter contents in the soil decreased, the loose/tight value increased,and their increase range of Kos value was lower than that of non-tillage. Also,different culure had little effect on FA, HA and HA/FA value. |
