 PAGE \* MERGEFORMAT 21 植烟土壤对烟草生长及烟叶品质的影响研究 摘要 在世界经济中，烟草生产占有十分重要的位置。近年来，烟叶质量成为烟草行业关注的焦点。烟草原料决定着卷烟产品质量，生产出优质的烟叶是烟草市场发展的必然走向，相关研究表明，烟草质量受栽培技术、生态环境、遗传等因素的影响。而植烟土壤环境是烟草生长主要的生态因子之一，在很大程度上决定烟叶质量，选择适宜的土壤是优质烟生产的重要环节。因此，适宜的土壤环境条件是烟草优质试产的基础，本论文主要从土壤类型与质地、肥力、化学性状、重金属和农药四个方面阐述其对烟草生长及烟叶质量的影响，并对今后植烟土壤环境的研究进行了展望。 关键词：土壤；烟草；品质；影响 Abstract In the world economy, tobacco production occupies a very important position. In recent years, tobacco quality has become the focus of attenti -on of the tobacco industry. Tobacco raw material determines the quality of cigarette products, production of high-quality tobacco is the inevitable trend of the development of the tobacco market, related research shows that the quality of tobacco by the cultivation technology, ecological env -ironment, genetic and other factors. The tobacco growing soil environ- ment is one of the main ecological factors of tobacco growth, to a large extent, determine the quality of the tobacco leaf, select the appropriate soil is an important part of the production of high quality tobacco. Suita -ble soil environment condition is, therefore, a high-quality tobacco trial production based, this paper mainly from the four aspects of soil type and texture, fertilizer, chemical properties, heavy metals and pesticides on its effects on tobacco growth and quality of tobacco leaves, and prospects for future planting tobacco soil environment research. key word：soil;tobacco;quality;influence 目录  TOC \o 1-3 \h \z \u  HYPERLINK \l _Toc451965386 摘 要  PAGEREF _Toc451965386 \h 2  HYPERLINK \l _Toc451965387 引 言  PAGEREF _Toc451965387 \h 4  HYPERLINK \l _Toc451965388 1烟叶品质  PAGEREF _Toc451965388 \h 5  HYPERLINK \l _Toc451965389 2 土壤类型与质地对烟草生长及烟叶品质的影响  PAGEREF _Toc451965389 \h 6  HYPERLINK \l _Toc451965390 2.1土壤类型对烤烟生长发育的影响  PAGEREF _Toc451965390 \h 6  HYPERLINK \l _Toc451965391 2.2土壤质地对烤烟生长发育的影响  PAGEREF _Toc451965391 \h 7  HYPERLINK \l _Toc451965392 3土壤肥力对烟草生长及烟叶品质的影响  PAGEREF _Toc4
