| 摘 要： | 通过不同氮素形态及配比对烤烟生长发育和产质影响的研究,发现在基肥中随着硝态氮比例的增加,可促进烟株早期生长;增强烟株对花叶病和赤星病的抗性;提高烟叶产质、上等烟比例及内在品质,但当硝态氮的比例达到50％时这种正效应均达最大,以后变化不大。由此可以认为基肥中硝态氮比例达到50％是生产上烟叶优质适产的理想值。

| Abstract: | Effect of different ratio of nitrogen forms on growth and production quality of flue-cured tobacco leaves was studied. The results showed that increase of NO3-N application in basal manure could improve the early growth and development of tobacco plants,enhance the resistance to mosaic disease and brown spot, raise the quality of leaves,percentage of upper-grade leaves and leaf inner quality. When the rate of NO=N reached 50%,role had been greatest. Hence, 50% of NO=N application in basal manure was the ideal value for producing fine quality leaves and rational yield in practice. |
