Description
Technical Field
The invention relates to the technical field of tobacco cultivation, in particular to a method and a system for cultivating Fujian fresh, sweet and fragrant high-quality tobacco leaves based on a transplanting period.
Background
Ecology is a key factor determining the quality of tobacco leaves. The planting period is different, the illumination condition, the temperature condition, the rainfall and the air humidity of the tobacco in the growth period are different, and the quality, style and characteristics of the produced tobacco leaves are different. Therefore, the determination of the proper transplanting period is an important factor for fully excavating the advantages of local climatic conditions, improving the quality of the tobacco leaves and showing the style and the characteristics of the tobacco leaves.
The Fujian plot is in the situation of 'mountains and seas', belongs to the subtropical marine monsoon climate, and is full in rain and sufficient in illumination. The change of the historical daily average temperature of the Fujian smoke area is characterized in that the temperature is lowest in 1 month, about 7-12 ℃, and the lowest temperature can reach-5 ℃; after 2 months, the air temperature gradually rises; the highest day average temperature is reached in 7-8 months, about 27-30 ℃, and the highest temperature can reach 39 ℃ in the daytime.
Currently, the Fujian tobacco district mainly depends on experience to determine the transplanting time, the transplanting time is from 1 to 4 months, and the transplanting time is deeply fixed in the brain of the producer of the Fujian tobacco district. However, in the existing transplanting mode of Fujian tobacco region, the low-temperature cold (freezing) damage occurs in the early stage of the tobacco growth period or the high-temperature sunburn phenomenon occurs in the later stage of the tobacco growth period. The low-temperature cold (freezing) damage causes the sudden increase of the permeability of the plasma membrane of the tobacco cell, causes the outward penetration of the cell content, causes the metabolic imbalance of the plant, causes the damage to the plant, and causes the obvious reduction of the quality of the tobacco leaves and even the yield reduction and the absolute harvest of the tobacco leaves. The damage to plant growth caused by excessive temperature is called thermal damage, and is greatly related to the degree and duration of high temperature. The high temperature causes the respiration to be larger than the photosynthesis, the stored nutrients are consumed, and the plants are scorched and even die after the long time, so that the yield of the tobacco leaves is reduced and even the tobacco leaves are not harvested. Meanwhile, the high temperature reduces the synthesis of necessary coenzyme, interrupts the relevant metabolic activity, generates biochemical damage, reduces the synthesis speed of protein, passivates the activity of enzyme and causes the quality of tobacco leaves to be obviously reduced.
Therefore, from the current situation, the reasonable adjustment of the transplanting period is imminent, and is one of the key measures for improving the quality and yield of Fujian tobacco leaves.

According to the thickness and density states of the tobacco leaves, the identity of the tobacco leaves is divided into five grades of thin, medium, thick and thick according to the difference size which can be perceived by human senses.
The oil content of the tobacco leaves refers to a soft semi-liquid or liquid substance contained in the tobacco leaves, and reflects the degree of greasiness, fullness and dryness from the appearance of the tobacco leaves. According to the oil content state and sensory feeling of the appearance of tobacco leaves, the national standard of the existing flue-cured tobacco divides the oil content into 4 grades of less, slightly, more and more.
The chroma refers to the saturation degree, the uniformity and the gloss intensity of the surface color of the tobacco leaves. Chroma comprises three layers: the color uniformity, plumpness and glossiness of the tobacco leaves. The uniformity degree refers to the state that the colors of the surfaces of the tobacco leaves are uniform; the fullness refers to the shade of the color; the gloss intensity indicates the visual intensity.
The tobacco maturity refers to the maturity of the cured tobacco, and comprises two aspects: the first means that under the condition of sufficient nutrition, the tobacco leaves grow and develop to the mature degree, namely the maturity of field fresh leaves. And the second step is to collect the mature tobacco leaves and to achieve the mature degree after modulation. The maturity is divided into 5 grades of pseudo-maturity, under-maturity, still-maturity, maturity and complete maturity.
The specific evaluation method of the appearance quality comprises the following steps: scoring by an evaluation group consisting of 5 experts with tobacco leaf grading technicians and the qualifications, wherein the full score of each index is 100, the minimum scoring unit is 1, the higher the score is, the better the evaluation is, calculating according to an arithmetic average method after the scoring is finished to obtain the average score of each evaluation index, and keeping the integer according to a rounding method.
The specific evaluation method of sensory evaluation comprises the following steps: scoring by an evaluation group consisting of 5 or 7 experts with provincial or national cigarette evaluation committees, wherein the full score of each index is 10 points, the minimum scoring unit is 0.5 point, the higher the score is, the better the evaluation is, and after the scoring is finished, the score which is closest to the average score of each evaluation index is selected to be calculated by an arithmetic mean method and is the final score.
In addition, in the sensory evaluation results, "middle-bias" means that the main body is the faint scent type, and the middle scent type style characteristic is provided; the 'partial strong' refers to the main body of the fragrant style and has the characteristic of strong fragrant style; the strong and transparent fragrance is characterized in that the strong fragrance style is taken as a main body, and the fragrant fragrance style is provided.
In addition, in the sensory evaluation results, "clear with sweet" means that the main body is fresh and sweet, and the sweet is brought back; the expression "clear with scorched" means that the main body is a sweet and fresh feeling, and the main body is scorched and sweet; the expression "scorched with clear" means that the scorched sweet is mainly used as the main body and the scorched sweet is simultaneously used as the main body.
