| Tobacco leaves are a special commodity and with a single use. China is one of majorworld tobacco producer whose leaf yield of tobacco ranks the first and account for half that oftobacco in the world; if it allows its tobacco production to blindly expand, enormousresources will be wasted. Furthermore, because of Chinese people'raised living level and thechallenges WTO and WHO has presented, its development of tobacco production withhigh-quality tobacco leaves in a planned manner has become the first priority among all thepriorities of tobacco production. Therefore, the zonization for high-quality flu-cured tobaccofarming appears very urgent in china. While Mr. Chen Ruitai et al Carried out the zonization of tobacco farming of china, theyonly took into account adaptability and limitation with ecological conditions chosen as thecriteria for the zonization, and thus the zonization apparently can not meet with therequirements of tobacco quality resulting from Chinese people's raised living level as well asthe requirements of the zoned tobacco farming occurring after saturated market of tobaccoleaves. Accordingly, the Study of ecological and geological zonization for high-qualityflu-cured tobacco farming through overall analysis of the adaptability, timeliness,practicalityand scientificalness of tobacco farming on purpose of further zoning the regions of tobaccofarming appears very important and significant. Relying on the research achievements of tobacco farming zonization and taking into fullaccount the practices of tobacco in the regions of tobacco production in china, the paperanalyzes the climatic, geological, soil backgrounds and tobacco qualities in the regionaforesaid by means of the mythology of resource analysis, thereby promulgating the criteria,setting the regional goals, planning the zonization of flu-cued tobacco in the region aforesaid,and thus providing references for high-quality production and development of Chinatobacco. The major results of this analysis are as follows: 1. This is the first time for the zonization of flu-cured tobacco farming to have beenconducted in china according to climatic, geological and soil backgrounds. In the zonization,the regions of tobacco farming were divided into two zones, five belts and eleven sub-zones.The two zones are the area of high-quality flu-cured tobacco farming in south china and theone in north china: the five belts are the belt of high-quality flu-cured tobacco farming inYunnan-Guizhou highland, the one covering south Hunan, south Jiangxi, west fujian and eastGuangdong, the one occupying the hills and low mountains in Qinling and Daba ranges, theone standing in west and central Henan, and the one lying in the regions of Central Shandongand south Anhui with gentle slope mounds and shallow-valley hills. The eleven sub-zonesare(1) the sub-zone of high-quality flu-cured tobacco farming occupying west and centralYunan,(2) the sub-zone of high-quality flu-cured tobacco farming occupying west and centralGuizhou, (3) the sub-zone of high-quality flu-cured tobacco farming located in WuyiMountains of east Sichuan, (4) the sub-zone of high-quality flu-cured tobacco farmingspanning west Huan and south Jiangxi,(5) the sub-zone of high-quality flu-cured tobaccofarming covering west Fujian and east Guangdong, (6) the sub-zone of high-quality flu-curedtobacco farming comprising of south Shannxi, and Nanyang region of Henan,(7) the sub-zoneof high-quality flu-cured tobacco farming covering west and north Hubei, (8) the sub-zone ofhigh-quality flu-cured tobacco farming in west Henan, (9) the sub-zone of high-qualityflu-cured tobacco farming in central Henan, (10) the sub-zone of high-quality flu-curedtobacco farming in central-south Shandong, and (11) the sub-zone of high-quality flu-curedtobacco farming occupying the south regions of central Shangdong, and south Anhui. 2. The research shows that there are nine basic climatic conditions in the regions ofhigh-quality... |
