| To study the baking properties of Hongda varieties in southeast rainy ecological area, an experiment
was carried out to research the different turn-yellow temperatures and turn-yellow degree during the yellowing period
through the use of smart ovens. The results showed that Hongda leaf tips and leaf margins had rapid dehydration and
were hard to turn yellow in the yellowing period, difficult to drain in the later yellowing stage and color-fixing stage,
the yield per unit area and average price were relatively low, but the tobacco leavescolor was orange, chroma was
concentrated, oil was enough and smell was prominent after baking. Hongda various parts of leaves with the treatment
had higher turn-yellow temperatures and turn-yellow degree during the yellowing period, its fresh- dry ratio was
relatively small, appearance quality was better, chemical composition as well as coordination was better, overall
economic traits were higher. The quality of Hongda tobacco leaves was better in the use of higher temperatures (lower
leaves 40, middle leaves 39, upper leaves 38) and a higher degree of yellowing (turn the fire when 90% of
full -cured tobacco leaves after yellow tablets and blue veins) during the yellowing period under the ecological
conditions of Jiangxi province. |
