摘　　要：为土地平整后土壤改良措施的选择提供参考,在福建三明烟区进行稻草还田改良效果田间试验。结果表明:稻草直接还田及其发酵后还田均能增加土壤有机质含量、土壤田间持水量、毛管孔隙数、总孔隙数和排水能力,具有改善土壤物理性状,提高烟田保水性能和疏水性能的功效;能增加土壤团聚体含量,使土壤团聚体结构更为合理;还能增加土壤微生物数量,使微生物更加活跃。稻草直接还田及其发酵后还田均可明显增加烤烟产量和产值,其烟叶产量和产值分别增加12.33 kg/667m2、22.38kg/667m2和215.92元/667m2、678.10元/667m2。稻草直接还田与对照的产值差异不显著,而发酵后稻草还田与对照的产值差异显著。稻草发酵后还田可作为土壤改良的主要措施进行推广。The field experiment was used to study the effect of rice straw mulching on soil improvement in Sanming tobacco-planting area,Fujian and to provide a reference for the choice of formulating soil improvement measures after land consolidation.Results:Two fresh rice straw mulching and fermented rice straw mulching patterns both can increase soil organic matter content,soil water holding capacity,capillary pore number,total porosity number and water drainage capacity effectively improve soil physical properties,enhance water retention capacity and water drainage capacity of tobacco field,increase soil aggregate content and soil microbial quantity and promote microbial activity.Two fresh rice straw mulching and fermented rice straw mulching patterns both can increase yield and output value of tobacco obviously and tobacco yield and output value of the fresh rice straw mulching and fermented rice straw mulching pattern are 12.33 kg/667m 2 and 22.38 kg/667m 2,and 215.92 Yuan/667m 2 and 678.10 Yuan/667m 2 higher than CK respectively.There is no obvious difference in output value between the fresh rice straw mulching pattern and CK but there is a significant difference in output value between the fermented rice straw mulching pattern and CK.The fermented rice straw mulching pattern should be used as the main measure for soil improvement.
