The Influence of the Reserved Root and Transplanting Depth on Flue-cured Tobacco's Growth, Yield and Quality
摘要
Abstract
[Objective] To discuss the influence of retaining the best combination of taproot system and transplanting depth of flue-cured tobacco on tobacco growth,physical and chemical characteristics and economic traits.[Method] Taking Yunyan 87 as test material,split block design was adopted to conduct field test.With retaining taproot system as main treatment Ⅰ1,removing taproot system as main treatment Ⅰ2,transplanting depth 10 cm as assistant treatment Ⅱ1,transplanting depth 15 cm as assistant Ⅱ2,the reproductive period,agronomic characteristics of the field,tobacco leaf physical and chemical indicators,yield in each treatment were observed and recorded,effects of retaining taproot system and transplanting depth on tobacco growth,yield and quality were determined.[Result] The results showed that retaining taproot system and changing transplanting depth had significant differences on tobacco agronomic traits,physical and chemical indicators and economic traits;under the same main treatment,shallow planting (10 cm) was better than deep planting (15 cm),at the same assistant treatment it was better to retain taproot.[Conclusion] The most effective treatment is retaining taproot system,following by transplanting depth,the interaction effect is minimal.关键词
