摘  要:
以娄底市气象局历年(1981~2010年)气象观测资料和农作物生育期观测试验研究资料为基础数据,运用数理统计方法进行光合辐射和光合潜力计算。结果表明,娄底市冬半年的太阳总辐射值为38.546 0 k Cal/cm2,光合生产潜力可达34 162.5 kg/hm2,以经济系数0.4计算,则单位面积产量可达13 665.0 kg/hm2,光能潜力巨大。在此基础上,提出了娄底市冬半年光热资源利用的建议,认为该市非常有利于油菜和萝卜、白菜等喜凉蔬菜及绿肥的生长发育和高产。

摘  要:
The meteorological observation data( 1981 ~2010) of Loudi meteorological administration and growth period observation data of crops were used as basic data to calculate photosynthetic radiation and photosynthetic potential productivity. The results showed that total solar radiation was 38.546 0 k Cal/cm2, and photosynthetic potential productivity reached 34 162.5 kg/hm2. Taking 0.4 as economic coefficient, crop yield could reach 13 665.0 kg/hm2, which indicated that light energy utilization was rich. Based on this, utilization suggestions of solar-thermal resources in winter half year in Loudi were put forward. It was conducive to the growth and high production for green manure and vegetables such as rape, radish and Chinese cabbage.
