摘　　要：参照农业生物生长发育与太阳光照条件的关系,并根据试验资料,把太阳光照条件划分为暗光区、弱光区、中光区和强光区4级,其光照度分别为≤7×10^2,7×10^2-2×10^4,2×10^4-5×10^4,〉5×10^4lx.晴天条件下,太阳高度角≤0°的太阳光照条件为暗光区,0-20°为弱光区,20-37°为中光区,〉37°为强光区.According to the demands of crop and livestock for sunlight illumination condition, 4 zones, namely, dark light zone, weak light zone, moderate light zone and strong light zone were divided. The illumination intensity of these zones was divided as ≤7×10^2,7×10^2-2×10^4,2×10^4-5×10^4,〉5×10^4lx. The sunlight illumination conditions were further definited as follows： solar angle≤0° for dark light; solar angle from 0 to 20° for weak light zone; Solar angle from 20 to 37° for moderate light zone; solar angle 〉37° for strong light zone.
