【摘要】 光合作用是一个非常复杂的物理、化学和生物的过程,其影响因素也很多。概述了近年来作物光合作用和光能利用的研究进展,分析了作物个体的生理生态结构 ( 叶龄、叶位、叶绿素含量) 和群体状况等等内因对光合速率和光能利用的影响,探讨了作物生长所处外部环境 ( 光强、光质、水分、温度、CO2浓度、各种营养元素等) 对光合作用的制约机制,明确了各种农业技术措施在光能利用中的作用。更多还原

【Abstract】 Photosynthesis is a very complicated physical,chemical and biological process,which is affected by many factors.This article summarized the advances in photosynthesis and solar energy utilization research in crops,analysed the effects of eco-physiological structure(leaf age,leaf position,chlorophyll content) and population on photosynthetic rate and solar radiation utilization.The restricted mechanism by environmental conditions(light intensity,light quality,soil moisture,temperature,CO2 concentration,nutrient element and so on) on photosynthesis was also discussed.The roles of different approaches in solar radiation utilization were identified.更多还原
