对河南省濮阳市1954-2014年60多年来气温及日照变化特征进行分析,阐述了光温变化对农作物生产的响应分析措施,结果表明:近60 a来,濮阳市气温呈上升趋势,冬季增温明显,春季次之,夏季则有变凉趋势;日照时间总体呈减少趋势。结论认为:人类活动导致气候持续变暖,空气污染的加重导致日照时间减少;农业生产要根据农作物生长发育期光热资源变化特点,调整种植结构,优化农业布局,选择适宜品种,根据气候特点,确定适当的播种和收获时间,充分利用光温供需条件,趋利避害,达到高产丰收,保障农业可持续发展。
This paper analyzed the characteristics of air temperature and sunshine over the past 60 years from 1954 to 2014 in Puyang City, Henan Province, and analyzed the response of light temperature and temperature to crop production. The results showed that the air temperature in Puyang City was on the rise in the past 60 years, The temperature is clear, followed by the spring, while the summer there is a cooling trend; sunshine time overall showed a decreasing trend. The conclusion is that: human activities lead to continuous warming of the climate and the increase of air pollution, which leads to the reduction of sunshine time. According to the characteristics of light and heat resources in crop growth and development, agricultural production should adjust the planting structure, optimize the agricultural layout, select suitable varieties, Determine the appropriate sowing and harvesting time, make full use of light temperature conditions of supply and demand, profit and avoid disadvantages, to achieve high yield and harvest, to ensure sustainable agricultural development.
