[Objective]To provide references for the conditions of tobacco materials, tobacco distribution and tobacco storing, and observe the effect of microstructure, moisture and casing temperature on the adsorption rate of casing materials of flue-cured tobacco.[Method]The adsorption rate of smoked tobacco sheet was investigated by soaking method.[Result]The adsorption process of casing materials of tobacco leaf followed the second order kinetic equation. The number of pores in the flue-cured tobacco cross section was 17 - 76 times higher than that in the flue-cured tobacco foliage, and the pore rate was 33 - 183 times than that in the tobacco foliage, the tobacco was made from leaf to cut tobacco , the adsorption rate of casing materials increased from 2. 2 to 3. 1 times. With tobacco leaf moisture increased, the adsorption rate of tobacco leaf decreased. With the casing materials temperature increased, the adsorption rate of tobacco leaf increased.[Conclusion]To make flue-cured tobacco leaf into cut tobacco, improve casing materials temperature and reduce the moisture of tobacco leaf can help improve the adsorption rate of casing materials..%以辽宁省昌图县为例,采用p-中心法,以物流成本最小为目标,研究了与农业生产和物流联系十分密切的农业生产资料配送中心的选址问题.结果显示,在昌图县域范围内,县级配送中心建议布局在四面城镇.
