Abstract:
Taking ‘Jingyan Mini 2’ cucumber as experiment material，simulated the illumination of light at any point in the surface of the solar greenhouse at any time by using nonlinear regression method was studied，and established one model，and designed the indoor simulation calculation method of the direct radiation and scatter radiation.The results showed that the simulated values and measured values of the radiation intensity of illumination decision coefficient of sunny day (R2=0.995 2，RMSE=8.841 2，RE=0.159 5，AE=3.413 2) were higher than decision coefficient of poor sunshine (R2=0.968 4，RMSE=12.015 6，RE=0.075 6，AE=7.573 3).In sunny day，the radiation intensity of illumination measured was 23 W?m-2?s-1 at 7:30 am，but the value was 62 W?m-2?s-1 at 8:00 am in poor sunshine，poor sunshine which was 30 minutes later than the sunny.In poor sunshine situation，the measured value was 226 W?m-2?s-1and the simulation value was 237 W?m-2?s-1 at 12:00，but the measured value was 404 W?m-2?s-1 and the simulation value was 400.257 W?m-2?s-1 at in sunny situation，the sun′s radiation was half less in poor sunshine day than that in a sunny day.Therefore，the light radiation in the solar greenhouse could be predicted by the model of solar irradiance.
