不同种植模式对烤烟生长及产质量的影响

目的]在泸州烟区开展烤烟(Nicotiana tabacum)不同种植模式探索研究。方法]分析测定烟株农艺性状指标、抗病性、原烟外观质量、烟叶内在化学成分及产量产值等经济效益。结果]不同种植模式和地膜覆盖方式对烤烟生长发育和产质量的影响十分显著,宽垄双行两边地膜覆盖,中间稻草覆盖的种植模式比较适合泸州烟区的烤烟生产。结论]该研究可为生产出工业喜好的中间香型烤烟品种,满足工业对优质原料的需求,推动泸州烟叶持续健康稳定的发展提供科学参考。

Effects of Different Planting Patterns on Growth, Yield and Quality of Flue-cured Tobacco(Nicotiana tabacum)

Objective] To carry out the flue-cured tobacco of different cropping patterns in Luzhou region.Method] The indicators of tobacco plants of agronomic traits,disease resistance,and appearance quality of the raw tobacco,tobacco intrinsic chemical composition and production output value of indicators on economic benefit were determined and analyzed.Result]The results showed that the different cropping patterns and film covering methods had very significant effects on flue-cured tobacco growth and development and production quality,thereinto,the planting mode of two rows planting in wide ridge,the plastic film covering its two sides and straw covering its middle part was suitable for the flue-cured tobacco production in Luzhou region.Conclusion] The study provides a scientific reference for producing the middle flavor types of flue-cured tobacco varieties meeting the industrial production,then satisfying industrial requirement to good raw materials,and promoting tobacco leaves sustainable,health and stable development
