移栽期对香料烟伊兹密尔生育及产质量的影响

Effect of transplanting time on development,yield and quality of Izimir

2001年10～12月在保山怒江流域进行了移栽期对香料烟品种伊兹密尔生育期、产量和香气品质影响的试验，结果表明，香料烟品种科库鲁伊兹密尔的最佳播种期在9月中下旬，最佳移栽期在10月下旬和11月上旬。此期移栽的香料烟大田生育期较长，干物质积累较多，产量较高；并且叶片小而厚，香气质好，香气量足，吃味丰富，经济效益较好。随着移栽期的推迟，烟叶香气品质以及产量均依次降低。

The effect of different transplanting time on development, output and aroma quality of Izimir was studied at Luoming from October to December of 2001, The results showed that the oriental tobacco transplanted in the last ten days of October or the first ten days of November grew longer relatively after transplanting, accumulated more dry matter, produced relatively higher output. Also the tobacco leaf was little and thick under such climatic conditions, its quality of aroma was better, the quantity of aroma was abundant, and the economic benefits were better. The aroma quality and output were reduced sequentially with postponement of transplanting time.
