摘要
试验比较了两个烤烟品种K326、云烟85的催芽型烤烟包衣种和常规包衣种对漂浮育苗中出苗时间、出苗率以及根系、叶片干鲜重、根系活力等的影响。结果表明,催芽包衣种能显著提高漂浮育苗的出苗率,特别对提高出苗的速度和整齐度,缩短出苗时间有较好的效果;催芽包衣种可以增加烟苗的株高,促进根系的生长发育;催芽包衣种的烟苗地上部和地下部干物质积累量都明显高于常规包衣种的烟苗;催芽包衣种对漂浮育苗烟苗的根系活力有明显的增加作用。
A test was conducted with two flue-cured tobacco varieties K326 and Yunyan 85 to study the influence of primed and pelleted seeds on germination time germination percentage fresh and dry weight of roots and leaves and the root activity of seedlings produced by float system. Primed and pelleted seeds could significantly increase the germination rate and showed definite influence on speeding up the germination and uniformity it could also promote plant height the extension of stem root development root activity biomass accumulation both in aerial part and underground.
