麦烟套种是比较成熟的套种模式,特别是在当前缺乏有效的防治花叶病的化学药剂,而花叶病又时常大面积流行的情况下,实行麦烟套种具有更重要的意义。但是,麦烟套种在烟叶生产中应用的较小,这主要因为套种小麦易与烟叶争光、争水、争肥,如若套种模式不合理或田间管理技术跟不上,则会导致烟叶长势弱、颜色淡、油分少、产量低;若氮肥过多则导致叶片水分多、叶片厚、不易成熟、不易烘烤、品质差。试验研究和生产实践证明,在肥水条件好的地区,发展麦烟套种完全是可行的。关键是要掌握调控技术,即配套措施必须跟 Intercroping with wheat and tobacco is a relatively mature intercropping model. Especially in the current lack of effective anti-Mosaic chemicals, Mosaic tobacco intercropping is more important in the case of Mosaic disease. However, the use of wheat-tobacco intercropping in tobacco production is relatively small, mainly due to the fact that intercropping wheat is likely to compete with tobacco leaves for water and fertilization. If the inter-planting pattern is not reasonable or the field management techniques can not keep up, Light color, less oil, low yield; if nitrogen fertilizer is too much lead to more water leaves, thick leaves, not easy to mature, not easy to bake, poor quality. Experimental research and production practices have proved that it is perfectly feasible to develop a wheat-tobacco intercropping system in areas with good fertilizer and water conditions. The key is to master the control technology, that is, supporting measures must be followed
