Studies On Reserve Flue-cured Tobacco Varieties Screening And Supporting Technology In Ning’er

How to optimize the layout of flue-cured tobacco varieties in Ning’er.Through the comprehensive testing and demonstration from tobacco varieties screening, style characteristics, transplanting period, harvesting, fertilization methods and other quality flue-cured tobacco production technology,the results obtained:1. The results of Reserve Flue-cured Tobacco Varieties screening:Yunnan Tobacco 110 is better than K326 in Growth period. Yunnan Tobacco 110, Yunnan Tobacco203 and Yunnan Tobacco105 is the best reserve Tobacco Varieties in main agronomic traits Botany properties,NC71 and Yunnan Tobacco317 is better than K326. NC71 is the best reserve Tobacco Varieties in Disease resistance,Yunnan Tobacco203 and Yunnan Tobacco317 is better than K326. NC71 is the best reserve Tobacco Varieties in Economic characters, Yunnan Tobacco 105 Yunnan Tobacco203 Yunnan Tobacco317 is better than K110. Comprehensive above factors,NC71 and Yunnan Tobacco 105 is the best reserve Tobacco Varieties in Ninger.2. The results of Reserve Flue-cured Tobacco Varieties style characteristics:Yunnan Tobacco 105 is the best reserve Tobacco Varieties in agronomic traits Botany properties,NC71 is better than K326. NC71 is the best reserve Tobacco Varieties in Resistance to raises a gender,Yunnan Tobacco 105 is better than K326. NC71 is the best reserve Tobacco Varieties in Disease resistance,Yunnan Tobacco 105 is better than K326. Yunnan Tobacco 105 is the best reserve Tobacco Varieties in Economic characters, K326 is better than other varieties. Comprehensive above factors,Yunnan Tobacco 105 can be used as first reserve characteristics Pu’er Fen tobacco varieties, Because Yunnan Tobacco 105 is high yield and stable yield, wide adaptability, better quality, and Fen style is obvious. NC71 need to strengthen the supporting technology research.3. The results of Different transplanting period andharvest period on Yunnan Tobacco 105."The mining roasted loss is affected by different harvest period,especially after 14 days in flue cured tobacco, most for ripe tobacco leaves, disease spot is more, baked hard.Early transplanting and Normal transplanting will be better than after transplanting in the transplanting period. Normal harvest will be better than early harvest and after harvest in the harvest period. Delayed harvest 14 days will be harm to Yunnan Tobacco 105.4. The results of fertilization methods on Yunnan Tobacco 105:Look from fertilizer rate, with fewer fertilizer rate, the growth period of flue-cured tobacco is relatively short. Look from fertilizing, increasing number of fertilizer, can meet the requirements of each period in the growth and development of tobacco plant.5 days,10 days,15 days after transplanting each applied once 10% of the promotion of tobacco seedlings fertilizer and 30-35 days after transplanting fertilizer topdressing 40% is the best fertilizer and fertilization methods.
