河南地处中原,是我国农业生产的重要基地。一些作者在有关论文中,涉及到河南省的光合生产潜力、光温生产潜力和单季稻的生产潜力,由于论述角度不同,所得数值很不一致,而且都是一些概略数据,不能适应河南农业发展的需要。本文根据河南省的实际情况,初次估算了河南的作物光温生产潜力和郑州地区种植制度生产潜力,并对估算的方法和结果进行论述。 Located in the Central Plains, Henan is an important base for agricultural production in China. Some authors in related papers related to the potential of photosynthetic production, photosynthetic production potential of light and temperature and the production potential of single cropping rice in Henan Province. Due to different perspectives, the obtained values ​​are very inconsistent, and they are some rough data that can not meet the needs of agricultural development in Henan . Based on the actual situation in Henan Province, this paper first estimated the potential of crop production in Henan Province and the potential of cropping system in Zhengzhou, and discussed the methods and results of the estimation.
