| Abstract: | Energy environment characters of a silvopastoral system (apple-alfalfa) was studied in the drought hilly regions of Taihang Mountain. The results showed that the annual solar radiation to the system summed up to 49868.65GJ.hm~(-2).a~(-1), photosynthetically active radiation was 24244.67GJ.hm~(-2).a~(-1), the mean reflection rate of the system was 22.5%, which was higher than that of mono-culture orchard and the average transmission of the system was 18.0%, a little lower than that of mono-cultureapple. This indicated that more solar energy can be used in the apple-alfalfa system. |
