中文摘要:
      本文在前人研究成果的基础上,提出作物光合生产过程可分三个阶段分析其效率和限制因素,以确定各项参数建立计算方案,进行温度订正。并以河北省栾城县为例,计算了小麦、玉米、水稻和不同熟制的光热生产潜力。最后,对提高光热利用效率的途径进行了探讨。
英文摘要:
      The process of photosynthetic production of crop is divided into three steps for analysing their limiting factor and photosynthetic efficiency. On this basis, the parameters are determined and a calculation Scheme is established, meanwhile the temperature correction being made. Taking Luancheng as an example, the potentiaI productivities of wheat, maize, rice and for different cropping system have been investigated. Finally, some measures for increasing the potential productivity and the efficiency of utilization of light and heat are discussed.
