本文对吉林省中部地区玉米生长发育期间的水、热气候生态条件、气候生产潜力及最佳种植面积比例进行了系统的分析,并与吉林省西部和东部地区及中部其它主要作物进行了比较。结果证明:中部地区玉米的气候生态适应性明显高于其它区和中部其它作物,因而有发展玉米带的农业气候生态基础;中部玉米最优比例为总耕地面积的48.8%,明显高于其它区和其它作物。
This paper systematically analyzed the water and climatic conditions, the potential of climate productivity and the proportion of the best planting area during the growth and development of maize in the central area of Jilin Province. The results were compared with other major crops in the western and eastern parts of Jilin Province and central China. The results showed that: the climate and ecological adaptability of corn in the central region was significantly higher than other crops in other regions and the central region, and therefore had the agro-climatic ecological basis for developing corn belt. The optimal proportion of middle corn was 48.8% of the total cultivated land, significantly higher than other regions And other crops.
