How should the row orientation for jujube tree planting be determined to be reasonable?
The row orientation for jujube tree planting not only directly affects the growth and development of the jujube trees themselves, but also affects the growth conditions of intercropped plants. Jujube trees planted in north-south rows have a greater amount of accumulated light under their canopy than those planted in east-west rows. At the same time, jujube trees planted in north-south rows show little difference in light exposure time between the north and south sides, while jujube trees planted in east-west rows show a large difference in light exposure time between the north and south sides. Different row orientations not only affect light exposure time, but also cause differences in the amount of light received. From the perspective of the planting needs of the jujube trees themselves, north-south row orientation is the best. In addition, jujube
