摘要: 以烤烟品种龙江911为试材,通过田间试验,研究了黑麦草翻压对烤烟农艺性状、叶绿素含量、光合生理特性以及经济性状的影响。研究结果表明,黑麦草翻压能够促进烟株株高提高,株高比不翻压黑麦草+常规施肥(CK2)提高了21.89%、14.75%、10.85%;改善农艺性状和光合生理特性,增加产量和产值,产值比对照(CK2)提高了5.27%、24.89%和2.13%,进而提升了烤烟的经济性状。黑麦草翻压第二批烤烟的农艺性状和经济性状相对较好。光合生理特性则是翻压第一批配施常规施肥较好。常规施肥和减量施肥多个指标差异不大,说明黑麦草作为绿肥可部分替代化肥。

Abstract: : Tobacco variety of 'Longjiang 911' was used as experimental materials, a field experiment was conducted to study the effect of returning ryegrass on agronomic trait, chlorophyll content, photosynthetic characteristics and economic character of flue-cured tobacco. The results showed that the overturning pressure of ryegrass could promote the growth of plant height. The plant height was increased by 21.89%, 14.75% and 10.85% compared with the control(CK2). The agronomic character and photosynthetic characters were improved, and increased the yield and output value. The output value increased by 5.27%, 24.89% and 2.13% compared with the control (CK2), thereby improved the economic character of flue-cured tobacco. The agronomic character and economic character of the second batch of flue-cured tobacco were relatively good. Photosynthetic characters are the best for the first batch of conventional fertilization(T1). There were no significant differences in conventional fertilizers (T1) and reduced fertilizers (T2), indicating that ryegrass as a green manure may partially replace chemical fertilizers.

Key words: flue-cured tobacco, ryegrass, overturning, fertilization, character comparison
