Luzhou-leaf Characteristics Yongzhou Variety Selection And Cultivation Techniques

In this study, Luzhou Yongzhou production practice of tobacco flavor in the careful analysis of Yongzhou tobacco-cured tobacco production conditions and quality status based on the launch manifest flavor characteristics of flue-cured tobacco type varieties, species and production technologies to improve the matching characteristics of key cultural technology in conducting research to improve production technology Yongzhou Luzhou tobacco measures. The main results obtained in this study are as follows:Characteristic varieties of tobacco:on the clouds through 87, K326, HY-9-7, Yunyan 85, KRK26, Hunan smoke on the 1st, clouds and other current planting 203 varieties of screening test, compared to related traits, research results show that K326 in the field growth stage, agronomic traits, botanical characteristics, resistance to other species with little difference. However, production Muping Muping value, high quality leaf ratio and the appearance quality of cured tobacco on the original, K326 has obvious advantages. To demonstrate Yongzhou Luzhou tobacco characteristics, need to vigorously promote the cultivation of K326 varieties.Characteristics of varieties suitable for transplanting date:transplant time were compared in different studies, the results show that full consideration of Yongzhou early July high temperature and weather conditions forced Maturity, Yongzhou appropriate early transplanting flue-cured tobacco, to promote early growth and quick pre-cured tobacco,7 of the mid to late to avoid the late mature forced mature climate conducive to high temperature. Suitable for transplanting date should be March 5 to 15 days is better.Characteristic species fertilization technique for high efficiency: through the comparative study of different fertilization methods, results show that double fertilization method to reduce the loss of the amount of fertilizer, high fertilizer use efficiency, nutrition supply full and tobacco vigorous growth, significantly increased the leaf area of tobacco, can to promote tobacco production, increase output, production value and high quality leaf tobacco ratio improved significantly.
