日照烟区烤烟最佳栽植密度研究

摘要

[Objective] To study the optimal planting density of flue-cured tobacco in Rizhao area.[Method] Field experiment was studied under the condition of different density on tobacco growth,dry matter accumulation and economic traits.[Result] With the increase of planting density,agronomic traits were worse,leaf area reduced,leaf area increased,dry matter accumulation decreased,while economic traits were better.[Conclusion]2.1 x 104 plants/hm2 is more appropriate planting density for NC55 which can get a better quality of production.%[目的]研究日照烟区烤烟最佳栽植密度.[方法]在大田试验条件下研究了不同栽植密度对烤烟生长发育、干物质积累、经济性状的影响.[结果]随着栽植密度增加,农艺性状趋差,单株叶面积减小,公顷叶面积增加,干物质积累量降低,经济性状综合表现变好.[结论] NC55品种在栽植密度为2.1×104株/hm2时较为适宜,可以获得较好的产质量.
