烟田施用有机肥对土壤理化性状和烟叶香气成分含量的影响

Influence of physico-chemical property of soil and the tobacco aroma composition by using organic fertilizer in the tobacco farmland

本试验研究了烟田施用不同数量草炭对土壤的有机质含量、理化性状、土壤微生物数量及烟叶中香气成分含量的影响。结果表明,烟田施用有机肥草炭8250～16500kg/hm2,随着施肥量的增加,土壤有机质、腐殖质含量,土壤真菌、细菌和放线菌数量均增加;烟叶香气成分中总醇量增加,总醛量减少,总酮量稍有增加。

Influence of using different amounts of peat on the soil organic matter, physico-chemical property,the quantities of soil microorganism and the composition of tobacco aroma was studied in this experiment.As a result,it indicates that after using the grass-carbon fertilizer 8250-16500kg/hm2,organic matter and humus of the soil,soil microorganism(including fungus,bacteria and actinonycetes) increase along with the amount of the peat.So does the total alcoholic of the tobacco aroma,but the total aldehyde is opposite.The total ketone increases a little.
