根据现代的研究资料,植物在光合作用过程中只同化太阳光谱380～710毫微米区间的能量。通常把绿色植物吸收的光带(380—710毫微米)称为太阳生理辐射。生理辐射是农作物产量形成的基本要素。因此,研究其强度、分布,对制定农业区域规划,搞好农业改制,利用生理辐射资源,具有重要意义。目前我区尚没有直接测定太阳生理辐射的资料。仅依间接气候计算方法,对汉中地区太阳生理辐射进行了计算。根据不同的太阳生理辐射利用率(2％、5％、10％),将全区
According to modern research, plants only assimilate the energy of the solar spectrum in the 380 to 710 nm range during photosynthesis. The band of light (380-710 nm) that green plants absorb is usually called solar physiological radiation. Physiological radiation is an essential element in crop yield formation. Therefore, studying its intensity and distribution is of great significance to formulating agricultural regional planning, improving agricultural restructuring and using the physiological radiation resources. At present, there is no direct measurement of solar physiological radiation in our district. Based on the indirect climate calculation method, the solar physiological radiation in Hanzhong area was calculated. According to different solar physiological radiation utilization (2%, 5%, 10%), the whole area
