Abstract


Comprehensive survey of tobacco in the Baoshan District of organic fertilizer application on the basis of the overall situation, through organic and inorganic fertilizer and the application of flue-cured tobacco yield and quality of oil dry on the effect of impact tests, in-depth study of organic and inorganic fertilizer on tobacco production, quality and aroma the impact of the results showed that:(1) Organic and inorganic fertilizer on the upper leaves of the main aroma components to a certain extent, test among treatments total sugar, reducing sugar content shows significant differences, among which the N 90Kg/hm2 and inorganic fertilizer 15000 kg/hm2 treatment; among treatments were significantly different, the upper leaves and water soluble chloride content of potassium in each treatment also showed significant differences.(2) With the increasing manure applied, the central leaves of total sugar, reducing sugar content reduced accordingly, to address the highest the N 97.5Kg/hm2and inorganic fertilizer 7500 kg/hm2treatment, all treatments showed significant differences; total nitrogen, nicotine and protein content is presented first and then decreased trend, which N 90Kg/hm and inorganic fertilizer 15000 kg/hm2 treatment of nicotine, total nitrogen, protein content lower than other treatments, the chemical components of coordination. Shows some farmyard manure to increase the ratio can be reduced to some extent, nicotine, total nitrogen, water-soluble chloride content, while increasing potassium content, on the improvement of tobacco quality has a positive effect.(3) With the increase in manure application rate of water-soluble chloride content of tobacco leaves corresponding increase in the field with too few soil chlorine to improve the quality of tobacco and tobacco into the wire rate.(4) As the proportion of organic and inorganic fertilizer increased, the central and upper leaves in petroleum ether extract content of a corresponding increase, while reducing the volatile acid content, increased content of volatile alkali, so acid-base balance in tobacco, chemical quality, more coordinated(5) Organic and inorganic fertilizer can increase the cured leaf boron, zinc, magnesium and other trace elements increase the content of tobacco leaf aroma, improve leaf quality.(6) Application of organic manure can increase the yield and production in the tested conditions, the nitrogen97.5kg/hm2,7500 kg combined application of organic manure (inorganic fertilizer and organic fertilizer 9.3:0.7) on the varieties of Baoshan Tobacco in K326 relatively suitable for optimal leaf production, yield.(7) Regardless of whether the application performances of the oil with dry leaves are mature, the chlorophyll content of middle and upper leaves of tobacco plants decreased. For the middle leaves, the chlorophyll is not applied the highest oil content was higher than dry processing facilities of oil dry treatment, but in the middle leaves are ripe, the oil content is lower than dry processing facilities. The upper leaves, then the performance of the facilities has been high in the two oil dry processing, the chlorophyll content than the control. Different ways of dealing with oil dry, middle and upper leaf chlorophyll content were expressed as dry fertilizer with the oil increases.(8) Under the experimental conditions, the nitrogen 96.75kg/hm2,600kg/hm2 cake fertilizer can enhance yield, quality and the rate of supper tobacco. The Baoshan Tobacco area in Yunyan 87 relatively suitable varieties can get the best tobacco production, yield.
