不同增温措施对烤烟苗床温度的影响

Effects of Different Temperature-increasing Measures on Seedbed Temperature of Flue-cured Tobacco

以中烟100的包衣种子为试验材料,研究了不同增温措施(苗床底部增温、苗床池水增温、小拱棚增温)对烤烟苗床温度的影响。试验结果显示:采取苗床底部增温措施可以明显提高育苗盘内基质温度,有效地促进烤烟的种子萌发和出苗,缩短烤烟的生育历期。

Taking the coated seeds of Zhongyan 100 as test materials, we studied the effects of different temperature-increas-ing measures （increasing the temperature of seedbed bottom, increasing the temperature of seedbed pool water, and increasing the temperature of seedbed through arched shed） on seedbed temperature of flue -cured tobacco. The results showed that the measure of increasing the temperature of seedbed bottom could significantly enhance the substrate temperature in seedling tray, effectively promote the seed germination and seedling emergence of flue - cured tobacco, and shorten the growth and developmental duration of flue - cured tobacco.
