| 摘 要： | 许昌烤烟适宜种植在化学元素带出的生态地球化学环境。产于分布在各级夷平面上的侵蚀剥蚀低山、丘陵、台地环境以及山前次生分散坡地和河间带机械分散高地等生态地球化学环境的烟叶品质优良。易溶有害化学元素积聚的地球化学环境不适宜种植烟草，平原特别是屏障洼地所产烟叶品质差。研究区土壤中烟草生产有益营养元素处于缺乏状态，并且缺磷，低钾。 |

| Abstract: | On the basis of regional geochemical data, through eco-geochemical environment survey, ecogeochemical characteristics of soil parent rocks, soil, water and tobacco in different-grade-tobacco growing areas are compared. Main geochemical indicators and geochemical compositions are measured. The relationships between the total and available amount of copper and other more than 40 elements, and tobacco quality are studied. The results show that Xuchang tobacco is suitable for growing in eco-geochemical environment where chemical elements tend to be taken out. Tobacco grown in such eco-environments is in good quality as erosion-denudation hill and platform of different-grade planation surface, secondary dispersed slope in front land, mechanical dispersed highland in inter-channel, and red soil, red.yellow soil formed in strong oxidation environment. Geo-chemical environment where soluble and harmful elements such as chlorine etc. are accumulated is unsuitable for tobacco growing.Especially in barrier depression of plain area tobacco is in poor quality. Paleosol layer is lurked geochemical reservoir of beneficial elements for tobacco growing. |
