宽窄行交替种植对烤烟产量和品质的影响

Effects of Wide and Narrow Row Planting Pattern on Yield and Quality of Flue-cured Tobacco

为了探明宽窄行交替种植对烤烟产量和质量的影响,以重庆烟区主栽品种云烟87为供试材料,采用3种不同的宽窄行交替栽培方式进行了研究。结果表明:采用宽行130cm,窄行80cm的方式进行种植能够有效地改善烟田生态环境及株间的通风透光条件,促进株高和叶面积的平衡生长,增加烤烟干物质积累,提高烤烟的产量和产值,并影响烤烟的内在品质,使其化学成分更加适宜和协调。

Yunyan 87,a major tobacco variety in Chongqing,was cultivated under three different wide and narrow row planting patterns to study the effects on yield and quality of Yunyan 87.The results showed that the wide row（130 cm） and narrow row（80 cm） planting pattern could effectively improve field ecological environment and the ventilation and light condition between tobacco plants,promote plant height and balanced growth of leaf area,increase dry matter accumulation,raise tobacco yield and output value,and perfect internal quality of Yunyan 87.
