商丘地区位于豫东平原东部,是黄淮海重点综合治理区之一。面积仅1万km~2。区域内除永城县东北部有小面积的剥蚀残丘外,其余均为平原。属南温带气候,夏季炎热,冬季寒冷。年平均气温在13.9—14.3℃之间,≥0℃的积温为5100—5300℃,多年平均降水量自西北向东南分布为653—874mm。太阳年总辐射量为48.32—51.16亿J/m~2。由于该区日光充足,水热资源丰富,季节分配与作物需求匹配相适宜,气候生产潜力大。如何科学地开发商丘地区农业气候资源,减轻农业气象灾害,是发展该地区农业生产的一项极其重要的战略措施。 Shangqiu area is located in the eastern part of eastern Henan Province, is the Huang-Huai Hai one of the key integrated management area. The area is only 10,000 km ~ 2. In addition to the northeastern Yongcheng County has a small area of ​​erosion hill, the rest are plain. It is a southern temperate climate, hot in summer and cold in winter. The annual average temperature is between 13.9-14.3 ℃, the accumulated temperature ≥0 ℃ is 5100-5300 ℃, and the annual average precipitation is 653-874mm from northwest to southeast. The total annual solar radiation is 48.32-51.16 million J / m ~ 2. Due to the abundant sunshine, rich hydrothermal resources, suitable seasonal distribution and crop demand matching, the climate potential has great potential. How to scientifically develop agroclimatic resources in Shangqiu area and mitigate agrometeorological disasters is an extremely important strategic measure to develop agricultural production in this area.
