What is the appearance of high-quality flue-cured tobacco and suitable for production? Which varieties of flue-cured tobacco have high yields?

In the practice of flue-cured tobacco cultivation, there is often a situation that good-looking (overly vigorous) tobacco may not necessarily be easy to bake, and high-yielding tobacco may not necessarily be of high quality. Jin, the phenomenon of blind smoke is also common. Therefore, it is also necessary to study the relationship between the field appearance and high quality and suitable yield of flue-cured tobacco.

So, what does high-quality flue-cured tobacco look like?

(1) The plant height is moderate, and the tobacco leaves are neither black nor violent. The growth of the tobacco plant is not too high or too vigorous, medium and moderate in growth. The leaves are green with yellow, flat and strong, soft and tender, and moderately thick.

(2) The seedlings are all uniform and grow uniformly. Having a sufficient number of plants and no shortage of seedlings is the basis for ensuring yield and a necessary condition for high quality. Only by growing neatly and uniformly can we have a good group structure, and can the tobacco leaves in the same part have a roughly consistent maturity period, so as to ensure yield and quality.

(3) Yellowing occurs in time and matures well. The most important sign of tobacco leaf maturity is yellowing. Timely yellowing is also a reflection of the internal chemical composition reaching a certain level. It must fade when it's time to yellow. Otherwise, the brown color will not turn yellow and will continue to darken, which will reduce the baking quality. But it's not just yellowing. In some places, fertilizers are lost, and drought also causes yellowing. This is not normal yellowing. The required yellowing should be timely maturity and timely yellowing.
