不同采收方式和成熟度对烤烟上部叶质量和经济效益的影响

摘要

The author studied the effects of different harvest ways and leaf maturity on the quality and economic benefit of upper leaves of flue-cured tobacco variety K326.The results showed that the technology of one -time picking and baking upper leaves with stalk together was superior to the technology of conventionally picking and baking upper leaves one by one , and it could promote the harmony of chemical compositions in tobacco leaves , and enhance the economic benefit for the peasants .When this technology was used to harvest the upper leaves with 90%~100%maturity, the flue-cured tobacco leaves had better appearance quality and more coordinative chemical compositions , and their baking energy consumption was lower , and their economic benefit was the high-est.%研究了不同采收方式和成熟度对烤烟品种K326上部叶质量和经济效益的影响。结果显示：上部叶一次性带茎采烤技术优于常规逐叶采烤技术，有利于促进烟叶化学成分的协调性和提高经济效益；当一次性带茎采收9～10成黄上部烟叶时，烤后烟叶外观质量较好，化学成分协调性较强，烘烤耗能成本低，经济效益最高。
