内蒙古西辽河流域特种玉米品种特性及气候区划

基于玉米本身的特性和用途的不同,将玉米分为高油型玉米、高淀粉型玉米、高赖氨酸型玉米和甜玉米四大类型.根据每种玉米品种对气候条件、土壤类型、地形特征等的不同需求,以通辽地区作为内蒙古东部西辽河流域玉米主产区的示范区,提出了特种玉米的区划指标,并利用GIS技术进行适宜种植区域划分.内蒙古通辽地区大部分农区适宜种植特种玉米,最适宜区、适宜区基本上均位于通辽南部和中部农业区.

Characteristic Analysis and Climatic Regionalization of Special-Variety Corn over West Liaohe Drainage Area of East Inner Mongolia

In order to increase the benefits and reduce the blindness of special-variety corn planting in the major planting area over the West Liaohe drainage area of the eastern Inner Mongolia, four special types of corns were selected as the research objects such as high-oil, high-amylum, high-lysine and sweet corns. Based on the needs of various corns for climatic conditions, soil types and topographic geomorphology, the planting regionalizing in- dexes of special-variety corn were presented with Tongliao as the demonstration area. By using of small-grid de- duction and GIS techniques, as well as the climatic similarity principle, the favorable planting areas for various special-variety corns were given respectively. It was pointed out that the most part of the agricultural area in Tongliao of Inner Mongolia is favorable for planting special-variety corns.
