【摘要】 为明确昭通优质雪茄烟叶生产技术，采用大田试验，以茄衣品种云雪36号为试验材料，在昭通金沙江流域研究遮阴与不遮阴对茄衣品种云雪36号生育期、植物学性状、农艺性状、抗病性、烟叶外观质量、化学成分及产质量的影响。结果表明：遮阴处理除顶叶终采收期缩短外，田间各生育时期较不遮阴处理有不同程度的延长，整个大田生育期缩短10 d;遮阴处理田间农艺性状显著优于未遮阴处理，表现为田间自然发病率低、烟叶质量表现较优、叶片薄；与国内外优质茄衣烟叶化学成分相比，遮阴处理后烟叶烟碱含量偏高，氧化钾含量偏低，其余化学成分相接近；遮阴处理产值为187 093.80元·hm^-2,显著高于不遮阴处理，比不遮阴处理提高54 493.80元·hm^-2。因而，在昭通金沙江流域的气候条件下，生产高质量的茄衣原料，大田期需进行遮阴栽培。更多还原

【Abstract】 In order to clarify the production technology of cigar tobacco leaves with high quality in Zhaotong, by taking the variety of cigar-wrapper tobacco leaves（Yunxue No.36） as the experimental materials, the field experiment was carried out to study the effects of shading treatment and non-shading treatment on the growth period, botanical traits, agronomic traits, disease resistance, tobacco appearance quality, chemical composition, yield and quality of Yunxue No.36 in Jinsha River Basin of Zhaotong. The results showed that: In addition to the shortening of the final harvest period of parietal leaves after the shading treatment, the growth stages in the field were prolonged to different degrees compared with that of the leaves without the shading treatment, and the whole growing period in the field was shortened by 10 days. The agronomic characters of tobacco leaves after the shading treatment were significantly better than those of the tobacco leaves without the shading treatment, which showed the low natural infection rate in the field, better quality of tobacco leaves and thin leaves. Compared with the chemical components in the cigar-wrapper tobacco leaves with high quality at home and abroad, the nicotine content of tobacco leaves after the shading treatment was higher, the potassium oxide content was lower, while the other chemical components were similar. The output value of tobacco leaves after the shading treatment was 187 093.80 yuan·hm^-2, which was significantly higher than that of tobacco leaves without the shading treatment(being 54 493.80 yuan·hm^-2 higher than that of tobacco leaves without the shading treatment). Therefore, under the climatic conditions of Jinsha River Basin in Zhaotong, it was necessary to carry out the shading cultivation during the field period to produce the raw materials of cigar-wrapper tobacco leaves with high quality.更多还原
