摘要
为筛选出品种特性较好,适应重庆地区生态环境的优良品种,采用大田对比示范试验,分团棵期、旺长期、打顶期测定不同品种的大田农艺性状,并在采收烘烤后,分部位测定初烤烟的化学成分,记录各品种的主要经济性状。结果表明,云烟97和中烟103农艺性状较好,但总体上中烟103化学成分更协调,且中烟103经济性状较好,产量和产值最高,并与其它3个品种差异显著。
To screen out the improved flue-cured tobacco varieties which may adapt to the ecological environment of Chongqing area,this paper studied the main agronomic traits of 4 flue-cured tobacco varieties at three stages（resettling growth stage,prosperous growth stage and top pruning stage） through the field comparative experiments.and then tested the chemical compositions of the leaves in the different parts of tobacco plants after baking.The main economical traits of every variety were recorded at the same time.The results showed that Yunyan 97 and Zhongyan 103 had better agronomic traits among four varieties,and Zhongyan 103 had more harmonious chemical compositions,better economical traits,and the highest yield and production value,which were significantly different from those of the other three varieties.
