Abstract:In order to better guide the application of leaves style regionalization of flue-cured tobacco in China, the main basis, process and characteristics of leaves style regionalization were analyzed. The nationwide regionalization of flue-cured tobacco leaves style follows the principles of "feature identifability, industrial usability, blending substitution, origin typicality and management operability". From four dimensions of ecology, sensory, chemistry and metabolism, tobacco leaves were divided into eight leaves styles. The border of adjacent aroma style was established according to ecological characteristics and the principle of respecting history. The typical producing areas of tobacco leaves with different aroma styles were determined based on the principles of outstanding and stable aroma styles, excellent ecological resources, standardized management techniques and large-scale. Sensory, ecological and chemical characteristics of leaves style were obtained by comparing tobacco leaves with different styles. Under the guidance of the regionalization results, cigarette manufacture enterprises can further improve the level of blending and raw material utilization, while producing areas can further highlight the characteristics of tobacco leaves.

Abstract:[Background] Stable moisture of vacuum pre-conditioner (VP) is of great importance to quality of cigarette. Since moisture content and temperature of flue gas inside moisture return machine are not measurable, hence moisture content at the outlet changes with the incoming material, steam and environment. A modeling and control system of tobacco vacuum moisture recovery was established in this paper to stabilize moisture content of output tobacco leaves.[Methods] A prototype of vacuum pre-conditioner was developed by increasing sensors and digital measuring to obtain data from inputs and outputs. Data were treated by patent methods. By establishing steady-state model and dynamic model of vacuum pre-conditioner, state variables (SVs) such as internal pressure and temperature of vacuum pre-conditioner, moisture content and temperature of cigarette packet were obtained. Experiments showed that the observation error was acceptable. For time-varying, nonlinear, time-delayed and multi-in-and-out controlled objects, the reference model of moisture maximization under the constraint of moisture return time was trained by digital simulation according to artifcial intelligence algorithm.[Results] Results show that:1) The system can increase moisture content by 2% to 6% under the condition that temperature of the cigarette packed core does not exceed 70℃; 2) The system can be used to stabilize outlet moisture, which is not affected by drastic changes of steam, water spray, smoke packet and environment.[Conclusion] The modeling and control system of vacuum pre-conditioner developed based on big data can achieve accurate observation and control of vacuum moisture reversion.

Abstract:[Background] To study the influence of contour and internal structure of the suspension chamber of ZJ17 cigarette making machine on pneumatic separation, and to determine design scheme of the suspension chamber.[Method] Fluent module in ANSYS Workbench was used to simulate and analyze suspension chambers with different contours and different internal structures. Pressure diagram, velocity diagram and motion trajectory diagram of internal airflow were compared. The simulation results were verified by computer experiments.[Results] (1) In the velocity vector diagram, the air flow in the square suspension cavity of the triangular block formed more eddies, which is benefcial to the separation of stems and labels. (2) It can be seen from the trajectory diagram that the airflow movement in the square suspension cavity of the triangular stopper was mainly helical, making the movement of the stem and tobacco shred more sufficient. (3) The average separation efficiency and shredding rate of the transverse triangular stopper device were 80.91% and 2.74%, respectively, which are better than the other two designs and in agreement with the simulation results.[Conclusion] The triangular stopper has better separation effect, which makes the stem separated from tobacco shreds more completely.

Abstract:In order to explore a more reasonable index weighting method in evaluation of fertility status of tobacco growing soil, soil samples from 12 leaf production base units of China Tobacco Jiangsu Industrial Co., Ltd. were collected. These soil samples were evaluated by single weighing method and comprehensive weighting method, respectively. Evaluation and weighing results were compared. Results showed that:(1) Soil pH, organic matter content, water-soluble chlorine content and content of physical clay<0.01 mm were 6.31, 3.4%, 30.64 mg/kg and 58.69%, respectively, which were suitable. The contents of available phosphorus and potassium were moderate, which were 28.76 mg/kg and 184.15 mg/kg, respectively. The content of alkali-hydrolyzed nitrogen reached 121.6 mg/kg, which was a high level. The contents of different effective trace elements were signifcantly different. (2) The highest weighting coefficients in three single weighting methods were 0.159 for soil pH index in AHP, 0.088 for available potassium index in standard deviation method and 0.168 for effective molybdenum index in entropy method. R2 mean for single weighting method was 5.25. (3) The maximum and minimum weight coefficients in the comprehensive weighting method were soil pH index (0.105, 0.098 and 0.103) and effective boron index (0.051, 0.059 and 0.052). R2 mean for comprehensive weighting method was 0.28. (4) The comprehensive weighting method based on the sum of deviation squares revealed larger gaps among evaluation scores, and the comprehensive weighting method based on game theory had better correlations among evaluation results, while the comprehensive weighting method based on unit constraints had higher evaluation scores. The weights calculated by three comprehensive weighting methods were slightly different, and the evaluation and ranking results were generally better than those of single weighting methods. Comprehensive weighting method was more consistent and reasonable, which was suitable for the evaluation of fertility index of tobacco growing soil.

Abstract:To better understand the status of tobacco-growing soil pH in Chenzhou, 1055 soil samples were collected in 2015, and the spatial variability of soil pH and its influencing factors were analyzed by multivariate statistics and geostatistics. Results showed that the average pH value of tobacco planting soil in Chenzhou was 7.00, ranging from 4.47 to 8.14; 10.91% of tobacco planting soil had pH less than 5.5, 62.37% of tobacco planting soil had pH greater than 7; the mean pH value of tobacco planting soil in each county ranged from 5.58 to 7.26.. Results of geostatistical analysis showed that the spatial structure of soil pH followed an exponential model, and the spatial variability was mainly determined by human factors. The spatial distribution of soil pH was high in southwest and low in Northeast. Partial least squares regression analysis showed that exchangeable calcium, silt, total phosphorus, total nitrogen, organic matter, alkali hydrolyzed nitrogen, cation potassium exchange capacity (CEC) and exchangeable magnesium were the main factors affecting the pH of tobaccogrowing soil. The accumulative explanatory ability of the eight indicators to the pH of tobacco-growing soil reached 65.2%, among which the VIP (Variable Importance Plot) value of exchangeable calcium was the largest. Soil pH vs. exchangeable calcium, total phosphorus, total nitrogen, organic matter, alkali-hydrolyzed nitrogen, cation potassium exchange capacity were in line with the linear plus platform model; while that vs. silt grains (0.02-0.002 mm) followed the linear model. The results of this study provide a theoretical reference for the improvement of acid tobacco planting soil, and is conducive to the sustainable use of tobacco planting soil in Chenzhou.

Abstract:Tobacco bacterial wilt in southern China can cause big economic losses. To understand the differences of soil microbial community structure between healthy and diseased soils and provide theoretical basis for the control of tobacco bacterial wilt, soil samples from healthy and diseased tobacco felds at different growth stages of tobacco plants were collected as research objects, and 16S rRNA and 18S rRNA genes were sequenced to analyze the changes in community structure and diversity of soil microorganisms. Results showed that the microbial community structure of soil in vigorious growth period had changed greatly compared with that before transplanting. The relative abundance of Actinobacteria decreased by an average of 5.4%, Actinobacteria increased by 8.0%, and Ascomycota increased by 22.8%. The relative abundance of unclassifed_f__Micrococcaceae in healthy soil was twice as high as that in infected soils, while the relative abundance of Pseudallescheria in diseased soil was twice that of healthy soil. The soil microbial diversity of healthy soil was higher than that of diseased soil. In conclusion, the microbial community structure differs between healthy and diseased soil, soil microorganisms such as unclassifed_f__Micrococcaceae, Pseudomycetes were the main species causing these differences.

Abstract:CRISPR/Cas9 is a new type of directional genome editing technology, which has been widely used in targeted editing of tobacco genome in recent years. CRISPR/Cas9-mediated multi-gene editing techniques have shown great potential in gene functional research and genetic improvement on many species. In order to explore the technical system of CRISPR/Cas9-mediated multi-gene editing in tobacco, a multi-target CRISPR/Cas9 system was constructed for five genes (PCS1, HMA2, eIF4E, TOM3 and TOM1) associated with different traits, and then transformed into Nicotiana tabacum variety K326 by using agrobacterium-mediated genetic transformation technology. Through screening of the positive plants, PCR amplifcation and sequencing analysis of genome DNA of target sites, it is shown that the established multi-target CRISPR/Cas9 system can be transformed into tobacco, allowing simultaneous mutation of 5 target genes. The positive rate of simultaneous mutation of 5 genes was 53.8%. The detection rate of a single gene mutation was between 76.9% and 92.3%. Further evaluation and analysis of the off-targets showed that no off-targets occurred at the predicted candidate sites. This indicated that the multi-gene CRISPR/Cas9 editing system constructed in this paper could effectively mutate multiple genes, which laid a foundation for the study of tobacco gene function and the improvement of multi-traits based on CRISPR/Cas9 technology.

Abstract:To clarify the difference of metabolic pathways of resistant tobacco varieties before and after infection by Meloidogyne incognita, experiments were conducted using the resistant tobacco variety G28 and the susceptible variety Changbohuang seedlings as test materials. A total of 4 treatments were set up:1) G28 inoculated with J2S suspension (G_RKN); 2) Changbohuang inoculated with J2s suspension (C_RKN); G28 inoculated with water (G_CK); 4) Changbohuang inoculated with water (C_CK). Each treatment was repeated 3 times. The changes of metabolic pathways before and after inoculation were analyzed by LC/MS technique. It was confrmed that the disease resistance-related metabolic pathways of resistant varieties G28 and susceptible varieties Changbohuang infected by Meloidogyne incognita were signifcantly changed, and the differential metabolites including many alkaloids, fatty acid, flavonoids, terpenoids, polyketones and other disease-resistant related substances had been identifed. Among them, 10 metabolic pathways were found signifcantly activated in the resistant cultivar, and only 5 of them in the susceptible varieties. From the perspective of metabolome, the difference in defense ability of resistant varieties after infection was revealed.

Abstract:At present, tobacco farmers' enthusiasm for tobacco planting is not high, the loss of high-quality tobacco felds is serious and the level of large-scale cultivation is low. Such problems have become the bottleneck restricting tobacco leaf production and development. It is therefore highly necessary to cultivate the new tobacco leaf trade entity under new situation. Aspects of strengthening the cultivation of professional tobacco farmers, optimizing the construction of tobacco farmers cooperatives, and introducing agricultural companies on a pilot basis have been looked into and suggestions on promoting the development of new tobacco leaf trade entity are put forward.

Abstract:To assess the research progress in capsule filter cigarettes, the history of flavor capsule (or bead) development, related technology, cigarette design, and safety assessment were reviewed based on published literature. The future prospect of flavor bead technology was discussed. Results showed that:1) The early patents and their layout on both the capsule cigarette or capsule in flter were mainly applied by individuals. The majority of these patents was designed or claimed to reduce harmful components in cigarette smoke. 2) Distinctive packaging designs with corresponding marketing and brand logos on the products and/or flters highlighted the product style and promoted the adoption of the capsule flter cigarettes around the world. 3) Capsule flter cigarettes were mostly favored by modern consumers, especially for younger adult smokers, for their new experiences in such aspects as physical touch, appearance, sound and sensory enhancements. 4) With regards to the delivery of aroma components from the bead, the capsule flter cigarettes were superior to other conventional flavoring methods. However, the transfer rate of aroma ingredients should be improved. 5) The addition of beads had no signifcant effect on cigarette consumption, biomarkers of exposure to consumers, and the formation of PM in environment smoke. 6) The impact of capsule flter cigarettes on smoke initiation was not widely studied. Auxiliary ingredients and materials, and combination technology with other innovative product designs need to be further studied.
