A: The orientation of jujube trees not only directly affects the growth and development of jujube trees, but also affects the growth of intercropping plants. The jujube tree planted from north to south had a greater amount of accumulated light under the crown than that from east to west. At the same time, the time difference between the north and south sides of the jujube trees planted on the north and south lines has little time difference, and the time on the north and south sides of the jujube trees planted from the east to the west varies greatly. The difference in the direction of travel not only affects the light receiving time, but also causes a difference in the amount of received light. Judging from the needs of the jujube tree itself, it is best to look from north to south. In addition, the planting of jujube trees has a great influence on the intercropping plants. The jujube tree planted between the north and the south will receive more light from the rows of crops. Even crops under the crown will receive partial light, and the east-west direction will be closer to the east and west. Crops on the northern side of the tree can receive very little light. Therefore, whether it is the use of pure jujube or jujube intercropping, the north and south are the best.
