摘要
与传统的单膜纸钵直播式和纸钵两段式育苗方法相比较，集约化（双膜塑料软盘式）烤烟苗的成苗特征及其烟叶的产量质量均有一些优势：根系发达，冠根比协调，烟苗健壮；根系活力强，光能利用率高，Ｎ代谢旺盛，抗病抗逆性强，生长势强，移栽后生长发育速度快；烟叶成熟时干物质积累多，产量、质量效益高。只是育苗一次性投资较多，水肥管理要求严格。因此，推广中应注意降低成本。
he collectivization young plant of fluecured tobacco (The young plant of thin plastics tray covered with double film),in comparison with the one sowing young plant or the two passage young plant in the paper bag with one film covered,are shown as follows on the fully seedling characters and the last development surperiority of yieldquality in the fields.Root system is very developed,and the relation of roots and crown are wellproportioned,so it grows healthy.The vigour of root system and the potention tendency of the seedling growth are higher,that utilization ratio of light energy and metabolism of N are speedly,and also its resistance stability is strong with fast growing speed in the tranplanting field.The plants have accumalated more dry matters during the maturation of tobacco leaves,and produce high yield and good quality.But inferiorities appear that the cost of growing young plant are bigger at first work,and the production management of filling water or applying fertilizer may be strict.As indicated above,we must pay attention to that so that it be popularized.
