Technical Field
The invention relates to a method for establishing a fresh tobacco leaf grade and quality judgment standard, and belongs to the field of tobacco.
Background
Since the implementation of the tobacco monopoly system, especially in the new century, the tobacco industry actively explores an independent innovation road taking Chinese cigarettes as development directions, so that the continuous healthy development of the tobacco industry is strongly supported, and technological innovation and structural adjustment become important components of the tobacco industry. Due to the influence of the whole economic environment, the tobacco planting and purchasing face severe market environment and self development pressure, and the future tobacco production mode change is dealt with, at present, the flue-cured tobacco planting and curing still needs a large amount of labor force, the problem of shortage of labor force is relieved, and the tobacco production mode needs to be changed urgently.
With the development of modern tobacco agriculture, specialized division is finer, and the separation of seed baking is a future trend, so that the method has positive pushing effects on reducing the labor of tobacco farmers, reducing the planting cost and promoting the sustainable development of tobacco leaves, and a set of perfect fresh tobacco quality judgment standard is needed on the premise of separating seed baking and purchasing fresh tobacco.
The current domestic fresh tobacco grading needs to explore own roads, in a large box baking mode, grading and grading of the baked tobacco are difficult, if the tobacco before baking can be graded, a certain basis is provided for grading the baked tobacco, in a seed baking separation mode, the fresh tobacco needs to be purchased, grading pricing is needed for the fresh tobacco, and the fresh tobacco grading standard is needed.
The research field of fresh tobacco leaves belongs to blank areas in China, and the related research is not found in China at present by the fresh tobacco grading standard, so that the research on the relevance of the fresh tobacco leaves and the grade of the cured tobacco leaves also explores a new field of the tobacco grading standard.
