太阳辐射能是地球上最主要的能量来源。和所有绿色植物一样,水稻的生物产量,主要决定于对太阳能利用率的高低。水稻是典型的喜温好湿的高产粮食作物,适应性广,世界各洲均有栽培,其中百分九十五分布在亚洲季风气候区域。福建紧靠北回归线,东临太平洋,气候温暖湿润,年平均气温为17—21℃,年雨量在1,200—2,000毫米之间,太阳辐射能量充足,光、温水同季,而且主要是分配在水稻生长季节里,更有利于发挥水稻高产优势。本文试从光、温两方面结合起来,探讨福建水稻生产问题。
Solar radiation is the most important source of energy on Earth. Like all green plants, the biological yield of rice is largely determined by the level of utilization of solar energy. Rice is a typical high-temperature, good-moist and high-yield food crop with wide adaptability and cultivation all over the world, of which 95% are distributed in the Asian monsoon climate region. Fujian is close to the Tropic of Cancer, east of the Pacific Ocean, warm and humid climate, the annual average temperature of 17-21 ℃, annual rainfall between 1,200-2,000 mm, adequate solar radiation, light and warm water in the same season, but mainly distributed in rice Growing season, more conducive to play a high yield advantage of rice. This paper tries to combine light and temperature to explore the issue of rice production in Fujian.
