Ecological Adaptability Of New Varieties Of Tobacco In Differential Elevation Tobacco Area Of The Changde Zone

Ecological adaptability of the flue-cured tobacco varieties, become a necessary stage of mass production of flue-cured tobacco introduction experiment more and more attention. The research about ecological adaptability of new varieties of Changdei in different altitude smoke District have not been reported. In this paper, the five new varieties of tobacco adaptability in the Changde different elevation tobacco area, physical characteristics and tobacco sensory quality assessment survey of the field trials on the three altitude of flue-cured varieties of tobacco agronomic status quo, the economic traits were compared and analyzed, Its main findings are as follows:1.Comparative analysis of different altitudes agronomic status and physical characteristics of the different varieties of flue-cured tobacco of tobacco plants after transplanting tobacco area of the three elevation30days,45days,60days and80days, several growth and agronomic traits during the dynamic observation of records and test analysis showed that:700m Altitude tobacco area of flue-cured tobacco varieties As the altitude increased much more by plant height, leaf number, pitch, stem circumference, maximum leaf length, leaf width, leaf area showed the greatest difference, performance, followed by550m altitude tobacco area,300m altitude tobacco area is relatively the most poor. Agronomic status of each species as follows:dynamic smoke No-4, clouds97in the whole growth period, most of the agronomic traits index was stronger with the control of K326, but the clouds97far better than the chips in smoke No-4, and smoke No-201, smoke XiangNo-3individual traits are superior to the control of K326.While the equilibrium moisture content through different altitudes smoke test species in the tobacco stem ratio, leaf weight analysis of the physical characteristics of these five species in the Changde three altitude overall performance of the clouds97> smoke No-4> smoke K326> Xiang smoke No-3> Tobacco201.2.Comparative analysis of different altitudes, different varieties in different parts of the flue-cured tobacco leaf chemical composition:from three different altitudes in the tobacco area total sugar, reducing sugar content, nicotine content, total nitrogen, chlorine content, potassium content and the alkali of the quality indicators of sugar, nitrogen base ratio, the ratio of potassium chlorine, the two sugar difference all aspects of a comparative analysis of the obtained with the altitude rise in total sugar content, sugar content, nicotine content, total nitrogen, chlorine content, potassium content showed smoke District:700m than550m tobacco area is higher than300m smoke District. Ingredients change with the trend of the leaf position of the lower leaves> upper leaves> middle leaves. Five cured tobacco varieties altitude leaf sugar alkali, nitrogen base than potassium chlorine than two sugar difference up to700m above sea level,550m above sea level, followed by300m minimum. Varieties of sugar alkali, alkali ratio of nitrogen, potassium chlorine than the variation of the leaf parts of the upper leaves> middle leaves> lower leaves; the variation of the two sugar poor leaf parts of the middle leaves> lower leaves> upper leaves. From the comprehensive analysis of the situation, the coordination of the overall performance of the three altitudes of different varieties of flue-cured tobacco chemical composition: smoke No-4> clouds97> Tobacco201> smoke K326> Xiang smoke No-3.3.Comparative analysis of the appearance of quality and quality of different altitudes of flue-cured varieties of tobacco smoking, indicating that the five flue-cured tobacco varieties in three altitude smoke appearance quality performance with altitude rising influence of performance for the700m>550m>300m. All varieties of B2F, C3F,, organoleptic evaluation with mixed samples of X2F grades of flue-cured tobacco smoking that varieties of clouds97, smoke No-4in the golden color of the three different altitudes in the tobacco area, the identity of thick oil foot, chroma and Hong temperament, the amount of aroma, odor, strength, finish, gray the score in the first place, especially clouds97is best. Compared with control K326, Tobacco201, Xiang smoke No-3different altitudes tobacco area of the color orange, the identity of thicker hybrid gas oil, chroma Hong temperament, the aroma was gradually increased, smaller, the momentum thicker, more comfortable finish, ash gray and more white. To sum up these consequences,it be thought that the five flue-cured tobacco varieties in the performance of the three elevation clouds97> smoke No-4> Xiang smoke No-3> smoke K326> Tobacco201.4. Comparative analysis of the five flue-cured tobacco varieties of Changde different altitudes smoke economic traits in the performance, inferred at different altitudes affect the degree of flue-cured tobacco varieties economic traits are for700m>550m>300m, the formation of the law of increasing from low to high. Five varieties in flue-cured tobacco smoke in three different zones show that exist in the yield and value differences, mainly for clouds97> smoke No-4> xiang smoke No-3> Tobacco201> K326(CK)The research of new varieties of tobacco in Changde at different altitudes in the tobacco area ecological adaptability of the performance show that the700m tobacco area is best,550ml tobacco area is second, and the300m smoke District is bad. For five flue-cured tobacco of ecological adaptabilities, followed stronger to weak by clouds97, smoke No-4, Tobacco201, smoke K326, Xiang smoke No-3. Changde is one of Hunan important quality flue-cured tobacco-producing areas, while the choice of quality varieties also need to consider these high-quality flue-cured tobacco varieties in the introduction to the ecological adaptation. So according to the research from the final five varieties were chosen in clouds97and smoke No-4for ecological adaptability strong flue-cured tobacco varieties, and the hope for local tobacco quality and efficient development and regional plant planning with reference opinions and to determine the local cultivars to provide a reference for quality and efficient development of the local tobacco.
