【Abstract】 The concept of diffusing index of direct solar radiation onthe greenhouse plastic surface is proposed in this study. Based on thedata of solar radiation observed inside and outsite the greenhouse,the diurnal variations and daily averages of the parameters includingthe albedo, transmissivity, diffusing index of direct solar radiationand the ratio of short-wave radiation inside the greenhouse to thatoutside are calculated and analysed.更多还原
