The Research On Substituted Medium And Cultivation Model Of Mountain Flue-cured Tobacco Of Gu Zhang County

This study explores the substituted medium and cultivation model of mountain flue-cured tobacco of Gu zhang county, and system analysis of the tobacco from seedling to bake, explore the seedling stage of different substrate on the influence of the tobacco seedling quality, in the field phase of different cultivation models, the influence of yield and quality of flue-cured tobacco and the investigation and evaluation of different substituted medium and cultivation model, explore the best substituted medium and cultivation model, and provide theoretical guidance for flue-cured tobacco production of Gu zhang county. The results showed that:50% corn residue+50% river sand can as substituted medium which is faster seedling leaf, seedling rate and seedling rate, good quality tobacco seedlings after transplanting agronomic traits better than CK, the physical characteristics and economic benefits than CK, the proportion of its corn residue and river sand suitable flue-cured tobacco in favor of growth and development, can replace the traditional medium. Flue-cured tobacco "covered well cellar " transplanting tobacco processing faster growth, better agronomic traits, good grilled tobacco after physical traits, chemical composition proportion, economic efficiency than the control. Flue-cured tobacco tillage cultivation process compared with the control, growth at a slower pace, somewhat less physical traits, chemical composition than the coordinated economic than the control. Flue-cured tobacco " covered well cellar " highest economic transplanting process, the average price of tobacco leaves, output value were the highest, compared with conventional cultivation measures to increase economic efficiency significantly, tobacco tillage cultivation process economic benefits lower than flue-cured tobacco" covered well cellar " transplanting, but higher than conventional cultivation model. Both two cultivation techniques in 55-60% penetration, comprehensive evaluation from the point of view of two cultivation techniques, tobacco "covered well cellar" transplant treatment has the better effect.
