摘要
通过田间观察、暗箱试验和烘烤试验研究了豫烟7号、豫烟9号和中烟100的成熟及烘烤特性。结果表明:不同品种间烟叶的成熟特性和烘烤特性差异较大。与中烟100相比,豫烟7号和豫烟9号田间生长旺盛、发育良好。豫烟7号品种落黄相对较晚,中上部烟叶能够分层落黄,成熟较慢,田间耐熟性较好,有利于上部烟叶养熟;烘烤特性表现为变黄相对较慢,前期失水较慢,"易烤性"不如其他两品种,中后期脱水速度加快,变黄和脱水速度同步性不易控制,但烟叶"耐烤性"较好。豫烟9号易熟性较好,田间较耐熟;烘烤特性表现为容易变黄,"易烤性"较好,易失水,变黄和脱水速度同步性易于控制,"耐烤性"较好。
The ripening and flue-curing characteristics of Yuyan No.7, Yuyan No.9 and Zhongyan100 were researched through field investigation, black-box tests and flue-curing experiments. The results showed that there were huge differences in ripening and flue-curing characteristics between different varieties. In comparison with Zhongyan100, the Yuyan No.7 and Yuyan No.9 grew vigorously and developed well in field. Among the two varieties, the Yuyan No.7 had relatively late ripe stage, and middle-upper tobacco leaves ripened layer by layer, thus having good ripe resistance and being beneficial for ripening of upper tobacco leaves; its flue-cured characteristics showed as following： yellowing slowly, slow dehydration in early stage, worse “easy-flue-cured ” characters than the other two varieties, accelerated dehydration rate in middle-late stage, hard control of synchronicity between yellowing and dehydration rate, but good at flue-cured tolerance of tobacco leaves. The Yuyan No.9 was ripening easily, and had ripe resistance in field; its flue-cured characteristics showed as yellowing easily, good “easy-flue-cured” characters, easy dehydration, easy control of synchronicity between yellowing and dehydration rate, and good flue-cured tolerance.
