篱式果园梯形树冠截面设计研究

Research on the Design of Trapezoid Crown Section in Hedgerow Orchard

利用天文三角公式计算太阳在不同纬度地区某日各时刻的位置,并计算在南北成行的条件下,满足光照条件的树篱的确形角。在满足光照条件下,依不同的冠高与冠间距的比值分析确定梯形树冠截面树篱适合的地理纬度,并利用前人的研究与该文相结合,进而讨论确定在不同纬度地区梯形树冠截面树篱的最佳参数,为在篱式果园中梯形树冠截面的设计提供理论依据。

This paper calculated the solar location in each time of different latitude area certain day using astronomical formula, and calculatd hedge definitive shape angle that can satisfy shining of the fruit tree, on the condition that from Southward to Northward in a row. On the condition that meeting the need of sun light,this paper analyzed and decided suitable geography latitude for the trapezoid crown section, according to different specific value of crown height to crown span, and made use of combination previous research results and this paper, and further discussed and decided the best parameter of hedgerow of trapezoid crown section in different latitude areas. A theory was put forward regarding the design of trapezoid crown section in hedgerow orchard.
