Description
Technical Field
The invention belongs to the technical field of tobacco leaf planting, and particularly relates to a planting method and a fertilizer for six tobacco leaves on flue-cured tobacco, which can enlarge the application range and the quality utilization rate of upper tobacco leaves.
Background
Currently, the tobacco industry and business in China generally consider the middle leaf to have the best quality. Most of the tobacco factories still use the middle leaves as main raw materials to produce the first and second types of cigarettes. This concept was developed in the past and was in line with the current practice of production. However, with the progress of the tar and harm reducing process of cigarettes, the usability of tobacco leaves is changed. The concentration of the middle leaf is lighter, and the cigarette is not suitable for low-tar cigarettes. In order to compensate for the lack of flavor of the middle leaves after tar reduction, the industry is biased towards tobacco leaves with stronger flavor and slightly higher nicotine content. The upper tobacco leaves have high smoke concentration and enough fragrance, and if the maturity is good and the miscellaneous gas is less, the usability of the upper tobacco leaves can be obviously improved. Since the 90 s of the 20 th century, the price of tobacco leaves has been adjusted abroad according to their availability. The industry also increasingly uses the method of matching upper tobacco leaves with proper lower tobacco leaves to improve the formula, and the limitation of middle tobacco leaves limits the large-scale development of the tobacco.
The upper tobacco leaves comprise all top leaves and part of the upper two shed leaves, each plant generally comprises 6 leaves, which account for 40 percent of the dry weight of the single tobacco leaf, and play an important role in the yield and quality of the whole plant of tobacco. However, in the flue-cured tobacco production in China at present, the upper tobacco leaves have the problems of unreasonable fertilization, unreasonable harvesting mode and time, high nicotine content of the tobacco leaves and the like.
According to the growth rule of the flue-cured tobacco, the upper tobacco leaves are parts capable of producing high-quality tobacco leaves due to sufficient nutrient supply, sufficient illumination and rich dry matter accumulation, and the upper tobacco leaves of the flue-cured tobacco occupy more than 40% of the yield of a single plant and occupy an important position in raw material production. At present, the quality of upper tobacco leaves in China has a large difference with international high-quality tobacco leaves and industrial requirements, and the difference is mainly expressed as follows: the leaf thickness, the tissue is compact, the green content and the impurity content are high, the nicotine is higher, the sugar-base ratio is low, the smoking irritation is large, the defects seriously limit the application range and the quality utilization rate of the upper tobacco leaves, and the main reason is that the top leaves in China can not be harvested in a real mature way.
