Abstract
This paper reports on the nature of total solar radiation on wheat throught its growing seasons in Peking district and the utilization of solar energy of different densities of wheat plant population at the brigades of Xujiawu and Tayuan. Basing upon the economical and biological yields of 400–500 kg per mu (1 mu=1/15 hectare), the rate of solar energy utilization are estimated to be 0.4%–0.5% and 1.17%–1.89% respectively. When compared with some otheer advanced brigades in Peking, these rates are lower than the average, and too far below the record rate of 5.09% From the standpoint of solar energy utilization, ‘observed rate of productivity, the intensity of photosynthesis and the relationship between the rate of solar energy utilization and yield there is enough potentiality to increase the yield per unit area. Finally the density of plant population per mu is also an important factor in the utilization of solar energy.
