| 摘 要： | 通过大田试验,研究了不同形态氮素配比及揭膜时期对烤烟生长发育以及产量、品质的影响。结果表明:(1)烤烟大田所使用的氮肥形态以铵态氮和硝态氮各50%配比,烟株在移栽初期生长优势明显,上等烟的比例较高;(2)烟田揭去地膜后,其揭膜效应在烟株移栽后60d表现出来,这样有利于后期上部叶开秸开片,提高烤后烟叶上等烟比例、均价和产值。 |

| Abstract: | A field trial was conducted to determine effects of different formulate of nitrogen forms and film-uncovering on growing, yield and quality of flue-cured tobacco. The results showed that when RN was 50%:50%, the early growing after transplant was better than RN was 70%:30% ones, and its yield of middle-high grad tobacco was best, The advantage of film uncovering showed after 60d of transplant, and its upper leaf size, the rate of first class leaf, the average price and the production value was best. |
