PRELIMINARY STUDIES ON HEAT BALANCE IN VERTICALLY CULTURED FOREST ON FARMLAND

Liu Kechang, Zhang Jixiang (Dept. of Basic Courses, Shandong Agri. Univ., Taian, China 271018) Li Desheng, Lin Quanye, Xu Munong (Dept. of Forestry. Shandong Agri. Univ., Taian. China 271018)  
The measured data of microclimate were used to calculate and analyse the instantaneous values and total daily values of various components of the heat balance at each observational spot in the vertically cultured forest and at the control spot on the open wheat field. The results showed that the instantaneous values and total values at various spots in the forest were different not only from those on the open wheat field, but also from each other. The measurements at the spots (Ⅱ,Ⅳ,Ⅴ) between the trees were all higher than those at the spots (Ⅰ,Ⅲ) under the trees and at the control spot(Ⅵ). Especially, the net radi-ation measurements between the trees were higher about 14 percent than at the control spot, which was greatly importart for improving the yield and quality of the fruit crops in the forest.
