- Abstract
The estimation of photosynthetic potential of rice can reflect the upper limit of its potential of production, and it is of great significance to improve the yield of grain per unit and ensure the security of grain in the future. From the point of view of solar radiation and sunshine hours, the photosynthetic potential of rice in 24 meteorological stations in Liaoning Province during the growth period from May to September was estimated by using Huang Bingwei theory. The results show that: during the study period, the average photosynthetic potential productivity of rice in Liaoning province was 25168 kg·hm-2, which showed a decreasing trend over time and the decreasing rate was 39.25kg·hm-2·(10a)-1.The spatial variation shows a trend of high in the northwest and low in the southeast.
