摘要
以云烟87为试验材料,采用电暖增温设备提高漂浮式水体温度的育苗方式(水体温度设置为18℃),研究了4个不同播种期对烟苗生育期、烟苗素质、大田烟株农艺性状及烟叶产质量的影响。结果表明:在耒阳市烤烟育苗生产中采用漂浮式水体增温育苗方式,播种期以上年12月22日左右播种较为适宜,比常温漂浮式育苗方式可提早7 d左右。
The raising method that using electro-warming device to increase water temperature of floating system was adapted to study influences of four different sowing periods on growth period and quality of tobacco seedling, agricultural characters of tobacco plant and yield and quality of tobacco leaves. The results showed that adapting floating system seedling raising method with temperature increasing during production in Leiyang city, the sowing period should be better at 22nd December last year, which 7 d advanced than floating system seedling raising method with normal temperature.
