| 摘 要： | 目的]探索适合兴山植烟区土壤改良的有效途径。方法]通过3年田间定位试验，研究不同翻压年限绿肥对植烟土壤理化性质及烤烟品质的影响。结果]连年翻压绿肥能够显著提高土壤孔隙度，降低土壤容重，与对照相比，翻压3年的处理土壤孔隙度提高了1．7％，土壤容重降低了3．6％。而且翻压绿肥能明显提高土壤有机质、碱解氮、速效磷、速效钾含量，调节土壤pH值，改善烟叶品质。且这种改善土壤理化性状和烟叶品质的趋势随着翻压年限的增加而增加。结论]翻压绿肥后土壤生物过程活跃，有利于土壤有机物质的转化和烤烟正常生长所需的营养供应。

| Abstract: | Objective ] The effective way of soil improvement for tobacco growing in Xingshan area was investigated. Method ] The effect of the different years＇ plowing green manure treatment on the physical and chemical property of soil and flue-cured tobacco quality was re- searched through the 3-year location experiment Results] The treatment of plowing green manure year by year can significantly increase soil porosity and reduce soil bulk density, and compared with the CK, the porosity of continual three-year＇ s treating soil was raised by 1.7% and the bulk density was decreased by 3.6%. And also, the content of soil organic matter, nitrogen, available phosphorus and available potassium was increased, the pH value of soil was adjusted and the tobacco quality was improved under the condition of the treatment. The improvement in both the soil physical and chemical properties and the tobacco quality was with the better trend with the year＇ s increment of plowing green manure. Conclusion] Mter the treatment of plowing green manure, the biological process of soil was more active, which was conducive to the transformation of soil organic matter and the nutrient supplied for normal flue-cured tobacco growth. |
