3. The harvesting method for distinguishing the quality style of the top cigarette of China green tea, China tea.

4. The harvesting method for distinguishing the quality style of the top cigarette of China green tea No. I according to claim 3, wherein the step 2) of harvesting the top 6 leaves at one time comprises the following steps: harvesting 6 leaves one by one or harvesting 6 leaves with stems one by one.

Technical Field

The invention relates to the technical field of tobacco blending, in particular to a harvesting method for revealing the quality style of top cigarettes of Cuilbi No. one.

Background

The upper tobacco of the flue-cured tobacco comprises all top leaves and part of the upper two shed leaves, which accounts for about 40 percent of the whole tobacco, and the yield and the first-class tobacco grade are higher, thus having higher industrial use value. The superior cigarette has great influence on the flavor and style of the cigarette, is an important raw material for producing high-grade cigarettes, and occupies an important position in the production of the raw material. Therefore, the research on how to improve the quality of the upper tobacco leaves is significant for improving the overall quality and economic benefit of the tobacco leaves.

The Cuibi No. I cigarette in Fujian cigarette area is a typical fresh, sweet and sweet flavor type characteristic variety, has the advantages of good cold resistance, high internal quality of tobacco leaves, strong usability and the like, and is a cigarette formula raw material of multiple industrial enterprises at present. However, the phenomena of ash hanging, green ribs and the like easily occur after the top tobacco of the first green tea is roasted in production, the first-class tobacco proportion is low, the sensory quality is poor, and the quality style display and the usability improvement of the first green tea special variety are seriously influenced. Researches find that different harvesting modes of upper tobacco can obviously influence the quality of the flue-cured tobacco leaves. However, the suitable harvesting mode of the Cuibi No. one top cigarette is rarely studied at present.

Therefore, how to provide a harvesting method for showing the quality style of the top cigarette of Cuilbi No. I. Is a technical problem to be solved in the field.

Disclosure of Invention

In view of the above, the first harvesting is performed after the 6 leaves on the top of the Cuibi No. I are fully mature, so that the first-class tobacco proportion, the middle tobacco grade proportion and the internal quality of the roasted tobacco are improved.

A harvesting method for showing the quality style of cigarettes on the top of Cuibi I comprises the following steps:

1) through a cultivation technology and a topping mode, the growth vigor of the plants is uniform, and the effective leaf number of the plants is kept to be 15;

factors determining the effective leaf number of tobacco plants: the cultivation technology (fertilizing amount, fertilizing mode, fertilizing amount and fertilizing mode adopted by different soil fertility and different climates are different), topping and leaf number retaining, and the cultivation technology and the topping mode ensure that the leaf number is kept to be 15 leaves, so that the upper tobacco can be harvested once, and the quality of the baked tobacco is improved.

2) When the upper tobacco is fully mature, harvesting 6 upper leaves at one time.

The technical effect achieved by the technical scheme is as follows: the upper tobacco is harvested once, so that the maturity of the tobacco leaves is improved, the leaves are fully developed, the leaf cutting is good, the identity tends to be moderate, and the quality of the fresh tobacco leaves is good. The test shows that the tobacco grade structure and the appearance quality after the roasting can be effectively improved by harvesting the upper 6 mature leaves once, and the economic benefit is improved.

The internal quality of the tobacco mainly comprises main chemical components of the tobacco and sensory evaluation quality, and the tobacco has good quality only if the chemical components are appropriate in content and the proportion is coordinated. When the upper tobacco is fully mature, the growth time of the upper tobacco on tobacco plants is prolonged, the balanced distribution of tobacco nutrients is promoted, the carbon and nitrogen metabolism is coordinated, the full conversion of tobacco contents tends to be coordinated, and the chemical component coordination is improved, so that the total sugar and reducing sugar content can be improved by harvesting 6 upper tobacco sheets once when the upper tobacco sheets are fully mature, the total nitrogen and nicotine content tends to be coordinated, the chemical component coordination is improved to a great extent, and the sensory evaluation quality is improved.

As a preferable technical scheme of the invention, in the step 1), the effective leaf number of the tobacco plants is ensured not to include 3 leaves in 15 leaves by adjusting the planting technology and topping and leaf retention.

The technical effect achieved by the technical scheme is as follows: when the number of the leaves is effectively 15, the cultivation of the plant type of the 'middle-sized tobacco' is facilitated, and the availability of the upper-portion tobacco is improved.

In a preferred embodiment of the present invention, in the step 2), the upper 6 leaves are the 1 st to 6 th leaves from the top.

As a preferable technical solution of the present invention, the harvesting of 6 leaves on the upper part in step 2) comprises: harvesting 6 leaves one by one or harvesting 6 leaves with stems one by one.

The technical effect achieved by the technical scheme is as follows: the 6-leaf one-time leaf-by-leaf harvesting mode is favorable for improving the upper equal tobacco proportion, the average price and the middle tobacco proportion; the harvesting of 6 leaves with stems at one time is beneficial to improving the proportion of the upper and middle tobacco, the style quality and the content of aroma substances.
