Different Fertilization Ways Of Cu,Yield And Quality Of Tobacco Variety On Liangshan Flue-Cured Tobacco.2

In this paper, different times and in different ways, a concentration of0.1%(CUSO4) foliar application of copper fertilizer, its physiological characteristics of flue-Cured tobacco, chemical composition, and the influence of the copper content of the tobacco leaves, designed to explore the different mode of application of copper fertilizer Liangshan flue-Cured tobacco.2growth and development, production output and quality change, and strive to find the best application time and mode of application of copper fertilizer, provide some references for the Liangshan flue-Cured tobacco.2production. The main results are as follows:1.Spray concentration of0.1%(CUSO4) of copper fertilizer on Liangshan flue-Cured tobacco.2growth period agronomic traits from the impact. On the whole, the processing plant height, leaf number, leaf length, leaf width, maximum pitch with the conduct of the flue-Cured tobacco growing season growth, but growth is not very obvious, stem girth have some reduction. By rosette copper micronutrient fertilizer spraying, flue-Cured tobacco in height, leaf number, leaf width, pitch increase only in the Popular for a long time stage spraying the flue-Cured tobacco leaf length, leaf width, pitch and stem girth were lower leaf width significantly lower than each of the other treatment.2.Spray concentration of0.1%(CUSO4) copper the fertilizer on Liangshan flue-Cured tobacco.2dry matter acCumulation plays an important role. With the advance of the growth period, the various processing whole plant dry weight, shoot dry weight indicators, there is a certain level of growth. Only in the rosette stage and only after topping flue-Cured tobacco in tobacco plant dry matter acCumulation, a boost role in the promotion of growth and development of flue-Cured tobacco, but only in a prosperous long-term spraying of flue-Cured tobacco of dry matter acCumulation some negative effects, not very conducive to the growth and development of flue-Cured tobacco.3.Spray concentration of0.1%(CUSO4) the copper fertilizer on Liangshan flue-Cured tobacco.2conventional chemical ingredients. Overall, a certain way of handling spraying concentration0.1%(CUSO4), grilled smoke sugars, nitrogen and nicotine content increased, decreased potassium and chlorine. Whether it is a single in the rosette stage, the vigorous or group rosette stage and the combination of vigorous spraying concentration to0.1%(CuSO4) of, after all help bake of tobacco increased two sugar content, the difference between the two sugar better than other treatments. spray concentration of0.1%(CuSO4)sugar to nicotine ratio of flue-Cured tobacco and nitrogen base indicators have some negative effects, helps improve the ratio of sugar alkali tobacco after topping spraying. For each growth stage, two sugar content gradually increased, other indicators of change varies, did not show the increase or decrease of certain regularity.4. Spray concentration of0.1%(CuSO4)of copper fertilizer on Liangshan flue-Cured tobacco.2yield and output value has a certain influence.Comprehensive tobacco plant growth dynamics and yield and output value of tobacco leaf, the results show that in addition to its prosperous for a long time in each period, each period combination spraying of0.1%(CuSO4)concentration can improve the growth condition of tobacco plant, improve the yield and output value of tobacco leaf, among them, especially in the group phase of the spraying effect is best.5.Spraying concentration of0.1%(CUSO4) the copper fertilizer plays an important role in the dynamic changes of the copper content of Liangshan flue-Cured tobacco.2. Overall, in the reproductive period, the copper content of tobacco leaves showed irregular changes, there were significant differences among the treatments. The cell spray only in the rosette stage in flue-Cured tobacco copper content decreased, and within the appropriate range, only in a prosperous long-term and only spray topping of copper content of flue-Cured tobacco in gradually increased, and the last beyond the appropriate range. Roasted smoke tobacco in the copper content in the various parts of the large differences in performance of the Cured tobacco upper leaf and middle leaf the basic copper content in the appropriate range. Lower leaves only group the trees of spraying processing tobacco copper content in the appropriate range.
