一、烟台地区的光、热资源概况太阳辐射强度是大气唯一热源,也是大田作物进行光合作用的唯一光能来源,更是决定一个地区作物产量的最大生产潜力的唯一根据.太阳辐射量的多少,与地理纬度的差异所造成的太阳高度大小有关,纬度越低,辐射强度越大.胶东半岛地处36～38°N First, the light and heat resources in Yantai Overview Solar radiation intensity is the only heat source of the atmosphere, but also the field of photosynthesis of crops the only source of light energy, but also determine the maximum production potential of a region’s crop production potential basis for the number of solar radiation , Which is related to the height of the sun caused by the difference in geographical latitude, and the lower the latitude, the greater the radiation intensity. The Jiaodong Peninsula is located at 36 ~ 38 ° N
