水稻生物产量有90～95％是来自绿色组织把太阳能转变为化学能的光合作用。因而其产量取决于太阳能利用率的高低。为探讨水稻生产发展问题,分析全省太阳能分布特点,是十分重要的。一、太阳总辐射分布特点太阳总辐射是通过建立经验公式推算的。目前一般是采用:Q=Q_0(a+b·s)的形式进行计算。式中,Q为欲求的各月总辐射值,Q_0为各高度、纬度、月份的理想大气中的总辐射量,S为各月的日照百分率,a、b为系数。据(?)等研究认为运用这个公式,由于(?)是按
90-95% of rice’s biological production comes from photosynthesis of green tissue that converts solar energy into chemical energy. Therefore, its output depends on the level of solar energy utilization. In order to discuss the development of rice production, it is very important to analyze the characteristics of solar energy distribution in the province. First, the distribution of the total solar radiation The total solar radiation is estimated through the establishment of empirical formula. Currently, it is generally calculated as Q = Q_0 (a + b · s). In the formula, Q is the desired total monthly radiation value, Q_0 is the total atmospheric radiation in each altitude, latitude and month, S is the sunshine percentage in each month, and a and b are coefficients. According to (?) And other studies that use this formula, because (?) Is pressed
