摘　　要：采用田间试验,采取定点动态监测的手段研究不同有机物料部分替代传统肥料,分析有机物料对烟田土壤基本性状和肥力及烟草生长性状的影响。结果表明:在烟株不同生长时期,稻壳生物炭处理土壤p H值都较其他处理有明显的升高;蚯蚓粪处理土壤有机质含量及CEC均保持在较高水平,试验结束期,有机质含量及CEC显著高于其他处理,比对照分别提高5.6%和6.2%。蚯蚓粪处理土壤全磷、碱解氮、速效磷、缓效钾含量显著高于对照处理,而土壤全钾含量却显著低于对照处理,而其他处理与对照差别不大。Through the dynamic monitoring at fixed points, this research conducted a field experiment to study the effects of different organic materials on soil basic properties, fertility and the growth characteristics of tobaccos after replacing part of traditional fertilizers with different organic materials. The results showed that at different growing stages of tobacco plants, p H value of the rice husk biological carbon treatment was of significant increase compared to other treatments, and soil organic matter content and CEC of the earthworm manure treatment were at relatively high levels. At the end of the experiment, the soil organic matter content and CEC of the earthworm manure treatment were significantly higher than those of other treatments, which increased by 5.6% and 6.2% than those of control, respectively. The contents of total phosphorus, alkaline hydrolytic nitrogen, available phosphorus and slowly available potassium were significantly higher than those of the control, while the content of soil total potassium was significantly lower than that of the control; other treatments were not different from the control obviously.
