烟草受遮蔽程度与种植密度的关系研究
Study on the Relationship between Shading Degree and Planting Density of Tobacco
摘要: 本文从对投影长度起决定性因素的太阳高度角和方位角出发，通过编程对假定的试验地点计算了既定时间内的太阳高度角和方位角，再根据所得太阳高度角和方位角的实时数据分析计算投影长度，并设计试验模拟了不同种植密度下烟草间的遮蔽情况，运用T检验从统计学的角度确定了较为适宜的密植密度，旨在为烟草等经济作物合理种植间距的选择提供参考。
Abstract:
Firstly, based on the solar altitude and azimuth, which are the decisive factors for the projection length, the solar altitude and azimuth in the given time are calculated for the assumed test site by programming. Then, according to the real-time data of solar altitude and azimuth, the projection length is analyzed and calculated. Finally, the shielding situation between tobaccos under different planting densities is designed and simulated, and the more suitable dense planting density is determined from the perspective of statistics by using t-test, in order to provide reference for the selection of reasonable planting spacing of economic crops such as tobacco.
