以G80、K326、云烟97和9506四个烤烟品种为试材,通过小面积的示范试验,考察了4个品种的大田生育期、植物学性状、主要农艺性状及经济性状等指标,并在此基础上分析总结了其各自的生长特性。结果表明:9506产量最高,云烟97产值最高,均可在浏阳烟区推广种植;而K326经济性状虽然比9506和云烟97差一些,但其产量和质量也在适宜范围内,有一定推广价值;G80虽然品质较好,但因其经济性状较差,需要合理的品种补贴才易推广。最后提出9506要严格控制种植密度,G80要严格控制种植密度和施肥比例,云烟97要严格控制播种期,云烟97和K326可以考虑适当密植等栽培建议。
Four flue-cured tobacco varieties G80, K326, Yunyan97 and 9506 were used as experimental materials. Through small-area demonstration experiments, the indexes of growth period, botanical traits, major agronomic traits and economic traits of four cultivars were investigated. Based on the analysis of their respective growth characteristics. The results showed that the yield of 9506 was the highest and that of Yunyan 97 was the highest, both of which could be planted in Liuyang tobacco growing area. However, the economic traits of K326 were worse than those of 9506 and Yunyan97, but the yield and quality of K326 were also within the appropriate range, Although the quality of the G80 is better, it is not easy to promote reasonable subsidies due to its poor economic performance. Finally put forward 9506 to strictly control the planting density, G80 to strictly control the planting density and fertilization ratio, Yunyan 97 to strictly control the sowing time, Yunyan 97 and K326 can be considered appropriate planting and planting recommendations.
