In order to make the flue-cured tobacco represent better aroma quality, an electronic nose with an array of metal-oxide gas (MOS) sensors are used to monitor the smell change during tobacco curing process. The design of dedicated electronic nose and experiment steps are described in detail. After signal preprocessing, the smell synthesized curve, of which four obvious peaks were detected, was obtained by the use of principal component analysis (PCA). The results indicate that, the peak time would be of important significance to the smell synthesized curve, which can clearly reflect the overall trend of smell during tobacco curing process. Therefore, back-propagation neural network (BPNN) is proposed to forecast peak time. This paper presents a study on smell change based on electronic nose during flue-cured tobacco process and detection of obvious peaks on the basis of sensor outputs. The law of smell changes obtained from analysis is in agreement with flue-cured tobacco theory.

In 3D digital urban planning applications, a model file may contain multiple building models, however, a single model or model component are very often needed to be used and operated independently. This paper studies 3D model segmentation and blanking technology in 3D urban planning. Three kinds of blanking and segmentation methods are in detail discussed. Finally, a 3D planning prototyping system is developed that include blanking and segmentation functions of the model. The experiment and their results verify the feasibility and efficiency of the method this paper proposed.

To realize the information management of tobacco infrastructure,the tobacco infrastructure information management system was designed and implemented based on business process and GIS display.The system consists of two subsystems: business process management subsystem and GIS display subsystem.The business process management subsystems primarily focus on supervision of work process,such as planning,design,bidding,construction,inspection and maintenance.The GIS display subsystem main focus on the display,query,statistic and analysis about tobacco infrastructure in 1:10000 electronic maps.The application results showed that this tobacco infrastructure management system could effectively strengthen the supervision and reduce ineffective investment of infrastructure construction.

Because of the problems that heavy pressure from the seventh coal Pillar Island faces of the-370m east roadway,and the stopping difficulties at Pang Zhuang Coalmine,Engineering practices demonstrated that island face mining was safely and effectively through improving the recovery process,strengthening the roof support.According to the problems encountered in the surface mining process and the technical measures involved,references are expected to be provided for similar mining faces.

In this paper,the flue-cured tobacco breeding work in Zunyi City was reviewd during the eleventh Five-year Plan and the problems in the flue-cured tobacco breeding work were analyzed.Around the demands for flue-cured tobacco varieties of the tobacco industry and the flue-cured tobacco production in Zunyi City,the proposals for the flue-cured tobacco breeding work in Zunyi City were put forward during the twelfth Five-year Plan involving basic research on germplasm resource,breeding objectives adjustment,detection ealuation system improvement for the target traits,breeding objectives achievement ways,regional application of self-developed varieties and so on.

The developing of modern tobacco agriculture needs the support of high-precision spatial information.The paper analyzed the positioning accuracy lack of traditional GPS technology applied in Guizhou mountain area.The principle,technical superiority and construction of RTK positioning technology were introduced.The application of RTK positioning technology in Zunyi modern tobacco agriculture was researched in this paper.

Plant growth-promoting rhizobacteria play an important role in plant growth.In order to investigate the effect of Brevibacillus brevis DZQ3 on tobacco growth and resistance of induction system,pot experiments were conducted in greenhouse and DZQ3 was inoculated into soaking root with filling root.Agronomic traits,biomass and chlorophyll content,leakage rate of electrolyte,systemic resistance related indices,including SOD,POD,PPO,PAL and CAT,and root development situation were measured.The results showed that the agronomic traits and biomass of tobaccos with application of DZQ3 were better than the control(CK),the difference were significant in 30 d.Systemic resistance related indices were better than the control(CK),the difference were significant in 60 d.These results indicate that PGPR strain DZQ3 can promote tobacco growth and induce system resistance,and also enhance disease resistant ability of tobaccos.

In order to identify the distribution of soil available silicon in Zhunyi tobacco area,87 soil samples of plow layers from Zhunyi county and Renhui county were analyzed.The results indicated that soil available silicon content ranged from 30.24 to 444.89 mg/kg,with an average of 169.75 mg/kg,and the variation coefficients was 73.27%.If using 100 mg/kg as the deficient critical point of soil silicon,20.69% of the soils were silicon deficient.Soil available silicon content was found that yellow soil calcareous soil rice soil,and in term of soil parent material,shale limestone dolomite marl dolomite limestone Quaternary clay yellow sandstone.There was no significant relationship between the soil available silicon content and the organic content or the altitude of sampling points,but there were significantly positive correlations between the soil available silicon content and the soil pH.

Main characters of six new flue-cured tobacco varieties were analyzed and compared to evaluate their comprehensive performance.The results showed that the comprehensive performance of MS96-7,Yunyan 100 and YH05 varieties was better than K326(CK),the yield,mean price and first-class tobacco rate of MS96-7 and Yunyan 100 were higher than K326,and the yield and mean price of YH05 were higher than K326 and the first-class tobacco rate of YH05 was similar to K326.

The economic characters,chemical composition and smoking quality of 6 new flue-cured tobacco lines bred by Zunyi Branch Company were evaluated comprehensively by using principle component analysis and fuzzy integrated analysis to provide a reference for breeding of flue-cured tobacco variety in Zunyi city.The results showed that the comprehensive performance of CZ-1 and MT-1 lines in six tested lines was better than CK(K326),the economic characters and chemical composition of CZ-1 and MT-1 lines were better than CK,and the smoking quality of CZ-1 and MT-1 lines was similar to CK.The comprehensive performance of the other tested lines was not as good as CK.

In order to supply micronutrients to tobacco fields, balance nutrition of tobacco plant to improve the quality of tobacco, the microelement contents in 356 soil samples of Zunyi tobacco-growing areas were determined, and their distribution was evaluated. Available Fe and Mn contents were very rich in the tobacco-growing soils of Zunyi with the mean of 32.51mg/kg and 69.09 mg/kg, respectively;Available Cu content was rich with 1.28 mg/kg; Available B, Zn and solution Cl were low with the mean of 0.71 mg/kg、1.35 mg/kg、11.71 mg/kg, respectively. Soil microelements contents had discrepancy in different ecology, altitude, agrotype, and county. According to the cluster analysis results, the soil samples of Zunyi were divided into 3 groups. The first group was Yuqing with high B, middle Zn, high Cu, middle Cl; The second group included Daozhen, Tongzi, Meitan, Fenggang, Wucuan with low B, low Zn, middle Cu, low Cl; The third group included Suiyang, Zheng'an with low B, low Zn, middle Cu, and middle Cl.
