摘要
通过不同播种时间对烟苗素质、烟株大田生育期、大田农艺性状及烟叶产质量影响的研究,结果表明:播种期对烟叶出苗率的影响不大;T3和T4(12月15日、20日播种)处理的烟苗,壮苗率最大,能够保证漂浮育苗中烟苗的素质,烟苗整齐度为整齐;烟株大田生育期适宜、农艺性状最佳;其培育出来的烟苗根系发达,易成活和早生快发,烟株经济性状最优。
The effects of different seeding time on quality of tobacco seedlings, growth period of tobacco plant in field, agricultural traits of tobacco plant in field, and yield and quality of tobacco leaves were studied. The results showed that the seeding time had little influence on emergence rate of tobacco seedling; T3 and T4（seeding in 15th, December and 20th, December, respectively） had the highest strong seedling rate, thus ensuring the quality of tobacco seedlings with floating cultivation and the uniformity of tobacco seedlings; the tobacco plants had the optimum growth period and the optimal agricultural traits in field; the roots of the tobacco seedlings were strong, so the tobacco plants can survive easily and grow quicker, and its economic traits was the best.
