Is there a way to turn the blue veins of flue-cured tobacco into yellow? (How to turn green flue-cured tobacco into yellow tobacco)

Green tobacco leaves refer to tobacco leaves that are cured with too much fertilizer before harvest, and have a dark green leaf color that does not fade. They do not turn yellow after curing and appear irregular or contain patterned green leaves.

Green smoke has a strong smell, is highly irritating, and has poor usability. When it is sold, it will reduce the grade and sometimes even fail to sell, reducing the income of tobacco farmers. Let's talk about the causes of green smoke and how to prevent it.

Reasons for blue smoke:

1. When harvesting tobacco leaves, take them home and dry them before they are ripe.

2. After heavy rain and high temperature, tobacco leaves were infested with diseases and insect pests. In order to reduce losses, a large number of immature tobacco leaves were purchased.

3. Too much fertilizer was applied in the later stage. After heavy rain, the tobacco leaves absorbed the fertilizer and turned green again without fading.

4. Improper handling during the harvesting and transportation of tobacco leaves causes damage and mutilation, which results in the fixation of chlorophyll.

5. The fresh tobacco leaves collected are exposed to the sun, causing them to lose moisture.

6. During baking, the temperature in the baking room is too high, causing the tobacco leaves to dry out prematurely.

7. The baking staff has poor skills and operates improperly.

Prevention and control measures:

1. When harvesting, wait until the tobacco leaves are mature before harvesting.

Second, apply fertilizer in moderation in the later stage to prevent the tobacco leaves from turning green again. After turning green again, spray potassium dihydrogen sulfate and expose to the sun to make the leaves turn yellow.

3. The tobacco leaf harvesting period is in the rainy season, and there are many diseases and insect pests, so pesticides should be sprayed in time for prevention and control.

4. When harvesting fresh tobacco, handle it with care and avoid exposing it to the sun.

5. Baking personnel can be trained in baking techniques in advance.

How to save the house if it has smoked?

For tobacco leaves that are more yellow than green, yellow with green, or blue veins with green, you can use plastic cloth to seal them tightly and cover them for about half a month. The green tobacco leaves will partially turn yellow.

Green tobacco leaves will lower the grade of tobacco leaves and damage the interests of tobacco farmers, so we must control every link to avoid the appearance of green tobacco.
