To investigate the conversion and supply mechanism of soil nutrients in tobacco field, determine scientific fertilization procedure and construct healthy soil environment, a field experiment was conducted with three soil treatments: without fertilizers (CK), with chemical fertilizer (CF), with organic manure and chemical fertilizer combination (MCF). Soil enzyme activities and bacterial community structures in the rhizosphere of flue-cured tobacco were studied. The results showed that comparing with CK, there was an increment of microbial carbon and nitrogen and a stimulation of enzymatic activities including dehydrogenase, invertase and urease in the soil of MCF treatment. The numbers of OTUs of 16S rDNA in the soils of MCF, CF and CK treatments were 291, 245 and 208, respectively; which belonged to 17 bacterial phyla, such as Proteobacteria, Actinobacteria, Firmicutes, etc. There were a lot of Nitrobacter and Nitrosospira. Among 20 dominant bacteria, the abundance of Cellulomonas, Fibrobacter, Coprococcus and Enterococcus was higher in the soil of MCF treatment than that of CK treatment, which was beneficial to organic matter mineralization and organic fertilizer utilization. Comparing with CK treatment, the abundance of Desulfobacter and Nocrdioides increased, and that of Acinetobacter decreased, while Rhizobium disappeared in the rhizosphere soil of CF treatment. The uniformity index and diversity index of bacterial community in the soil of MCF treatment was significantly promoted, the dominance index significantly reduced. In conclusion, MCF treatment improved soil environment and increased bacterial biodiversity, which were helpful to inhibiting the over reproduction of pathogenic bacteria and decreasing the disease risk of tobacco plants. © 2016, Editorial Office of Tobacco Science and Technology.

For comparing the effects of carbonization and liming of corn stalks on the promotion of soil fertility, yield and quality of flue-cured tobacco, field experiments were carried out to investigate the influences of different application methods on nutrient content, aggregate quantity, integrated fertility of soil, and consequently the yield and quality of flue-cured tobacco. The results showed that: under conventional fertilization condition, 1) The application of corn stalks increased soil organic matter and available potassium contents and improved the integrated soil fertility of renovated tobacco field and the sensory quality of flue-cured tobacco. 2) The application of corn stalks combined with liming reduced the acidification effect caused by corn stalks, and promoted the formation of macro water-stable aggregate in soil and integrated soil fertility. However, corn stalks combined with liming were not beneficial to yield promotion and coordination of chemical composition of flue-cured tobacco. 3) The application of carbonized corn stalks combined with liming improved the integrated soil fertility of renovated tobacco field. Meanwhile, it also promoted the yields and chemical composition coordination of flue-cured tobacco. Therefore, long-term application of carbonized corn stalks combined with liming was recommended for renovated tobacco field. © 2016, Editorial Office of Tobacco Science and Technology.

To make better use of waste tobacco stems and dusts, a field experiment was carried out for three consecutive years to study the influences of TOF (organic fertilizer containing waste tobacco from tobacco redrying factory) on the soil nutrients in tobacco fields, the incidence of tobacco disease, and the yield and quality of tobacco leaves. The results showed that: 1)In the TOF applied soils combined with CF(chemical fertilizer), the contents of organic matters were increased, soil pH did not change significantly, the content of alkaline hydrolyzed nitrogen was similar to that of CF treatment at late growing stage of flue-cured tobacco, while the contents of available P and K were significantly higher than those of CF. 2)Both TOF and COF (commercial organic fertilizer)significantly decreased the incidence and disease index of Tobacco mosaic virus, bacterial wilt, black shank and brown spot, and the control efficiency of TOF combined with CF was better than TOF. 3)There was no significant difference between the treatment of TOF combined with CF and the treatment of CF combined with COF in terms of the mean price, yield, output value and high and middle grade proportion of tobacco leaves. Comparing with CF treatment, the contents of potassium and total sugars in tobacco leaves in the TOF treatment combined with CF were increased by 22.51% and 12.43%, respectively; while the content of nicotine decreased slightly. Therefore, the fertility of TOF is similar to that of COF. © 2016, Editorial Office of Tobacco Science and Technology. All right reserved.

To study the relationships of routine leaf chemical components in medium flavor style flue-cured tobacco with the components in mainstream cigarette smoke, 31 tobacco leaf samples were collected from the planting areas of typical medium flavor style flue-cured tobacco in Guizhou, Chongqing, Shandong, Shaanxi and Heilongjiang. The correlations between the routine chemical components in tobacco leaves and the components in mainstream cigarette smoke were analyzed by correlation analysis, stepwise regression analysis and path analysis. The results showed that: 1)The release of total particulate matter (TPM), CO and tar in mainstream cigarette smoke significantly negatively correlated to the potassium content and significantly positively correlated to the chlorine content in tobacco leaves. Moisture content in mainstream cigarette smoke significantly negatively correlated to the potassium and reducing sugar contents in tobacco leaves. 2) The potassium and protein contents in tobacco leaves were two important indexes affecting the release of TPM and CO in mainstream cigarette smoke; and the contents of total sugar, potassium and total nitrogen in tobacco leaves influenced the moisture content in mainstream cigarette smoke greatly, as did the contents of total nitrogen, potassium and protein to the tar yield in mainstream cigarette smoke. Path analysis indicated that the chemical components in tobacco leaves positively or negatively indirectly affected the components in mainstream cigarette smoke, it suggested that there were promotion or inhibition between the chemical components in tobacco leaves and the components in mainstream cigarette smoke. Therefore, the contents of total nitrogen, total sugar, potassium and protein in tobacco leaves of medium flavor style flue-cured tobacco make the greatest contribution to the components in mainstream cigarette smoke, and the harmony between different chemical components in tobacco leaves is important to the release of mainstream cigarette smoke. © 2017, Editorial Office of Tobacco Science and Technology.

For effective supervision of tobacco infrastructure construction process, a GIS-based (Geographic Information System) tobacco infrastructure management system was designed, which was mainly composed of a Web GIS-based subsystem and a mobile GIS-based subsystem. Web GIS-based subsystem could manage infrastructure data in office via a computer and possessed more comprehensive functions, while mobile GIS-based subsystem could search and browse infrastructure data in filed via a mobile terminal (smart phone). The results of application in Zunyi of Guizhou showed that the system met the requirements of office work and mobile work and improved the management level of tobacco infrastructure.

Topography influences the density of soil sampling points for precise fertilization. In the case of high phosphorus and potassium fertilization for flue-cured tobacco, the soils in areas of plain, broad valley, narrow valley and gentle slope were sampled by 50 m×50 m grids and the available nutrients in soil samples were tested. The results showed that by Cochran formula, individual sample for plain, valley and gentle slope represented an area of 1.92, 1.01-1.56 and 0.73 ha, respectively at a confidence level of 90% and a relative error of 15%; by geostatistical method, the maximum sampling space for precise nutrient management were 234.0, 134.4-177.5 and 58.2 m for plain, valley and gentle slope, respectively. It indicated that sampling density should be increased gradually from flat to slope. ©, 2015, Editorial Office of Tobacco Science and Technology. All right reserved.
