摘要: 为明确高肥力烟田烤烟地膜覆盖栽培中适宜的揭膜时间,通过田间试验研究了高肥力烟田烤烟地膜覆盖不同揭膜时间对土壤养分状况、烤烟生物量和养分积累,以及烤后烟叶质量的影响。结果表明,高肥力烟田在不另外施用氮肥的情况下,烟株能够正常生长,烤后烟叶化学成分和感官评吸质量均较好;覆膜处理可减少土壤养分淋失;适时揭膜处理可有效提高烟株养分吸收利用率,以烟株团棵后10天(移栽后63天)揭膜处理烟株生物量和烟叶平均单叶重明显提高;烟叶经济性状最优。说明烟株团棵后10天揭膜更能促进烟株的生长,全生育期盖膜对后期烟株的生长有一定的抑制作用。

Abstract: In order to confirm the durations of disclosing plastic film in the tobacco field with high soil fertility, the effects of duration of film-covering were studied on soil nutrient, tobacco biomass, and quality through the field experiment. The results showed that, tobacco grew well and gained better quality without additional nitrogenous fertilizer in the tobacco field with high soil fertility. Soil nutrient losing under film-covering was less than that without film-covering. Tabcco with film-covering treatment had higher biomass and weight per leaf than those without film-covering. Film removing in 63 days benefited plant growth, and had the highest biomass comparatively, while film-covering for whole growth period restrained the plant growth in late period.
