摘　　要：试验于2003年9月至10月河南烟区的襄城县、舞阳县、叶县、罗山县4个试验点种植绿肥．2004年3月进行翻压，以研究绿肥对土壤容重、土壤pH值等理化性质的影响以及对土壤微生物的影响。试验结果表明，绿肥翻压可以有效地降低土壤的容重和土壤的pH值．提高土壤的有机质．同时能促进土壤中微生物数量的大量增加。与空白对照相比，各个处理土壤容重降幅为0．03～0．1g／cm^3，土壤pH值的降幅一般都在0．1～0.6，±壤有机质古量提高0．08％～0．1％。因此利用烟田冬季休闲空间种植和翻压绿肥，可作为提高土壤肥力、改善烟田土壤环境、实现烟叶生产可持续性发展的一个重要措施。in Henan province. The green manures sowed between the September and October in 2003 and the application of green manures was in the March of 2004. The treat ment of each green manure is 1/3 hm^2, and 1/15 hm^2 is the contradistinction in it. Results indicated that the application of green manuresmay decrease the soil bulk density affectively and adjust the soil pH, meanwhile it may also result the soil microbial biomass to increase greatly. The result shows Soil bulk density can be reduced 0. 03-0. 1 g/cm^3, the soil pH can be reduced 0. 1-0. 6 and soil organic matter can be increased 0. 08^- 0. 1% with the application of green manures. Thus, application of greenmanures may enhance the soil fertility and be favorable to the sustainable development of tobacco production.
