Abstract: The daily mean temperature of sowing can be reduced to 4℃from>10℃covered with plastic film in Ningxia. It means that sowing date may be moved up from Apr. 15-25th. to Mar. 21th-Apr. 5th. The average yield can be increased from 500 kg/mu to 600kg/mu. May get 800 kg/mu with advanced farming technigues. The rate of solar energy utilization can be raised from 1.9% to over 2% in 1980s.

Key words: Rice Potential resources of light and heat, Rice Potential resources of light and heat
