7个引进烤烟品种在环神农架地区的生态适应性

为了探明7个引进烤烟品种在湖北环神农架地区的生态适应性,筛选适宜在当地种植的优质烤烟品种,为当地烤烟生产的合理布局及优良烤烟品种的推广应用提供依据,于2006—2008年以云烟87、CF205、云烟202、中烟100、中烟103、K326(CK)和红花大金元7个烤烟品种为材料在湖北的竹山、房县、保康和兴山县4个试点进行了田间比较试验和生产示范,并对其农艺性状、抗病性、烟叶质量和经济性状进行了分析。结果表明:各品种在试验区域均能正常生长发育,其中,云烟87的农艺性状、原烟外观质量和评吸质量与K326相当,但抗病性较K326好,综合性状较K326优,是较理想的优良品种;红花大金元抗普通花叶病,化学成分协调性较好,但其他各项技术参数较差;CF205前期生长缓慢,生育期偏长;云烟202经济性状、评吸质量偏差;中烟100和中烟103的大田农艺性状表现较好。结论:7个烤烟品种中,云烟87和K326可作为优质烤烟品种在环神农架烟区推广种植。

Ecological Adaptability of Seven Introduced Flue-cured Tobacco Cultivars Around Shennongjia Region

Some field comparative experiments and production demonstration tests were conducted in four counties,including Zhushan County,Fang County,Baokang County and Xingshan County,to explore the ecological adaptability of seven introduced flue-cured cultivars(Yunyan87,Honghuadajinyuan,CF205,Yunyan202,Zhongyan100,Zhongyan103 and K326) around Shennongjia region,look for high-quality flue-cured tobacco cultivars which were suitable to grow there and to provide references for rational distribution of local flue-cured tobacco production,generalization and application of high-quality flue-cured tobacco cultivars.Meanwhile,the agronomic traits,disease resistance,flue-cured tobacco quality and economical characteristics were analyzed.The results showed that all cultivars grew well in test regions,Yunnan 87 was a good cultivar as its agronomic traits,apparent qualities of crude tobaccos and smoking quality of Yunnan 87 were equal to K326,disease resistance and integrated characteristics were better than K326.Some technology parameters of Honghuadajinyuan were worse than K326 except for a resistance to tobacco mosaic virus(TMV) and a good harmony of chemical components.CF205 grew slowly in the early stage with a long growth period.Yunyan202 displayed inferior economic traits and smoking quality.Zhongyan100 and Zhongyan103 revealed good agronomic traits.As a result,Yunyan87 and K326 could be selected as high quality flue-cured cultivars planting in the surrounding Shennongjia region.
