【摘要】 以当地主栽品种秦烟96和云烟87为对照,考察了烤烟新品系延安1号在豫西烟区的生育期、植物学性状、农艺性状、抗病性、外观质量和经济性状等指标,以评价延安1号在豫西烟区的生态适应性。结果表明:与对照相比,延安1号的长势较强、生育期较长,综合抗病性较好;烤后原烟多橘黄色,叶片结构疏松,身份中等,油分较足,色度较强;延安1号产量较高,产值分别较秦烟96、云烟87高7.03%、10.11%。初步认为,延安1号在豫西烟区的生态适宜性较强。更多还原

【Abstract】 Using the local varieties Qinyan 96 and Yunyan 87 as controls,the growth period,botanical characters,agronomic traits,disease resistance,appearance quality and economic traits of Yan’an No.1 were studied for its ecological adaptability evaluation in the tobacco area of western Henan.The results show that Yan ’an No.1 has stronger growth,longer growth period and better comprehensive disease resistance in comparison with the controls.Its primary flue-cured tobacco leaves are mainly orange yellow with loose leaf structure,medium identity,sufficient soft semi-liquid or liquid substance contents and stronger chroma.The leaf yield of Yan’an No.1 was 7.03% and 10.11% higher than that of Qinyan 96 and Yunyan 87,respectively.It is considered that Yan’an No.1 has a good ecological adaptability in the tobacco-growing area of western Henan Province.更多还原
