| 摘 要： | 以烤烟栽培品种龙江911为试材,研究其在无肥条件下,1、3、5 a茬栽培烤烟干物质积累规律和产量构成,产值状况。结果表明,不同的重茬年份烤烟干物质在整个生育期呈现出随着重茬年份增加而降低的趋势,不同重茬年份烤烟干物质快速积累期以及积累时间,积累量存在差异,1 a茬积累时期早于3 a和5 a茬,5a茬最终积累量最低;产量主要构成部分1 a茬为上部叶,3 a和5 a茬为下部叶;单位面积产值随重茬年份增加而降低。 |
| 关 键 词： | 重茬 烤烟 干物质积累 产值 |

| Abstract: | To study the accumulation of dry matter and changes of production value in different continuous cropping year of flue-cured tobacco,flue-cured tobacco cultivars Longjiang 911 served as material,the experiment was conducted in the field of 1-,3-,and 5-year continuous cropping of flue-cured tobacco without fertilization,and dry matter accumulation patterns and yield components were determined.The results showed that accumulation of dry flue-cured tobacco in the whole growth period reduced with the increase of... |
