不同植烟土壤改良模式对烤烟产质量的影响

摘要

The effect of maize stalk returning to field directly,green manures application,and its mixed pattern on yield and quality of tobacco of flue -cured were studied in order to explore the ways of tobacco -planting soil improvement.The results were as follows:the tobacco -planting soil improvement patterns of maize stalk return to field directly,green ma-nures application,and its mixed could improve tobacco the ratio of high quality,output and value of tobacco,enhance the length with leaf width proportion of tobacco and balance water ration,increase potassium content of tobacco,The best pat-terns of tobacco -planting soil improvement was the way maize stalk return to field directly and green manures application together.%为探索湘西州烟区植烟土壤改良方法，研究了玉米秸秆、绿肥、玉米秸秆与绿肥结合还田对烤烟产质量的影响。结果表明：玉米秸秆、绿肥、玉米秸秆与绿肥结合还田均能提高烟叶上等烟比例、产量和产值，提高烟叶开片率、平衡含水率和钾含量，以玉米秸秆与绿肥结合模式的土壤改良效果最好。
