移栽方式对梅州产区烤烟生长发育及产质量的影响

目的]确定梅州烟区适宜的移栽方式,解决移栽方式不合理引起的生物量积累少、化学成分协调性及产质量较差等问题。方法]以云烟87为试验材料,选取梅州平远产区,设置4个不同移栽方式处理,分别在烤烟团棵期、旺长期和成熟期测定农艺性状、干物质积累量和烤后烟叶常规化学成分。结果]不同移栽方式对烤烟的生长发育、物质积累、烤后烟叶常规化学成分及产质量的影响显著。井窖式膜下小苗移栽烟株在大田生长发育良好,物质积累较高,烤后各部位烟叶化学成分协调,产质量有明显的提高。结论]可以考虑在梅州烟区实际烟叶生产中推广应用井窖式小苗膜下移栽。

Effects of Transplanting Method on Growth Development,Yield and Quality of Flue-cured Tobacco in Meizhou Region

Objective] To determine the suitable transplanting methods in Meizhou tobacco-growing areas,the problems such as the accumulation of biomass,the coordination of chemical composition and the poor quality of production were solved.Method] With Yunyan 87 as the experimental material,the treatment of four transplanting modes in Pingyuan area of Meizhou was selected,the agronomic traits,dry matter accumulation and common chemical composition were measured in the flue-cured tobacco leaves.Result] The effects of different transplanting methods on the growth and development of flue-cured tobacco,the accumulation of matter,the conventional chemical composition and quality of flue-cured tobacco leaves were significant.The seedlings under the wellbore membrane seedling grew well in the field,the material accumulation was higher,the chemical composition of the tobacco leaves was coordinated,and the quality of the tobacco leaves was obviously improved.Conclusion] The transplanting under the cellar seedling can be considered and promoted in the actual tobacco production in Meizhou tobacco area.
