摘要
本文分析了青海粮食得以高产的光温资源基础 ,采用光照、热量条件订正函数 ,建立青海省粮食作物生长季光合生产潜力和光温生产潜力模式 ,分析了光合潜力和光温潜力的地理分布 ,在对粮食产区最大增产潜力探讨的基础上 ,提出了开发利用粮食单产潜力的有关对策。
This article analyses the light-temperature resources factors which promote the maximum grain yield in Qinghai.Using light-temperature resources response functions we established photosynthesis and light-temperature potential models in grain growth period in Qinghai,analysed geographic distribution of them.The author put forward some suggesting about how to exploit and utilize per unit area grain yield potential and maintain its sustainable development.
