摘要: 根据沙地水稻栽培试验资料,计算了科尔沁沙地奈曼旗的水稻光温生产潜力。沙地水稻的现实生产力与最大光能利用率为4%时的光温生产潜力较接近,进而分析了沙地水稻增产的主要原因,提出了沙地水稻增产的栽培措施。

关键词: 光温生产潜力, 水稻, 沙地

Abstract: The climatic potential productivity of rice is calculated according to the experimental data on sandy land in Naiman Banner.Inner Mongolia.The result shows that present productivity of rice on sandy land is approach to the light-temperature potential productivity with 4% maximum efficierry for solar energy utilization.In addition,the reason of high yield of rice in sandy land was analysed and the cultivation measures of raising rice yield were present.

Key words: Light-temperature potential productivity, Rice, Sandy land
