为明确烤烟上部烟叶一次性采收的适宜成熟度,以湖南桂阳烟区种植的'云烟87'为材料,设计低成熟度(M1)、中成熟度(M2)、高成熟度(M3)3个处理,开展6片上部烟叶采烤成熟度试验,并采用模糊评价方法对烤后烟叶质量和经济性状进行综合评价.结果表明,随上部烟叶采收成熟度提高,鲜烟叶的SPAD值下降;烤后烟叶微带青比例下降,杂色烟叶比例增加;烟叶成熟度提高,结构变为疏松,油分增多;烟叶单叶质量、厚度、叶面积质量、平衡含水率降低;烟叶总糖、还原糖、钾、淀粉含量下降,烟碱含量增加,化学成分可用性提高;但烟叶产量和产值下降.M2处理的外观质量指数较M1、M3分别高6.18％、-2.13％,物理性状指数较M1、M3分...

To clarify the suitable maturity for one-time plucking of six upper tobacco leaves,'Yunyan 87'was used as material,and three treatments of low maturity(M1),medium maturity(M2)and high maturity(M3)were designed to carry out the harvesting and curing experiments of different maturity of upper tobacco leaves in Guiyang tobacco area of Hunan,and the fuzzy evaluation method was used to comprehensively evaluate the test results.The results showed that as the harvest maturity of middle tobacco leaves increased,the SPAD value of fresh tobacco and propo...
