1 . 主要农艺性状

genetic and correlation analysis for agronomic traits in flue - cured tobacco., 烤烟主要农艺性状的遗传与相关分析.

1 . 农学利用率

under the N level of N1 , W1 had higher grain yield , higher grain absorption , higher N use efficiency , higher agronomic efficiency of N fertilizer and higher N partial factor productivity .N1水平下，W1处理获得了较高的子粒产量、子粒氮素积累量、氮素利用效率、氮肥农学利用率和氮肥偏生产力；

2 . 农学利用效率

the agronomic efficiency , physiological efficiency of N fertilizer in cropping rice was higher without N fertilizer in early season than those with N fertilizer in early season .早季不施氮小区的连作晚稻氮肥的农学利用效率、生理利用率比早季施氮小区高；

1 . 农艺措施

the progress of effects of different agronomic measures including fertilization , water regimes and transplantation , etc. and curing conditions on content of aroma components of tobacco was reviewed .综述了施肥、水分管理、移栽等农艺措施和调制工艺对烟草香气物质含量影响的研究进展。
