How should the planting density of jujube trees be determined to be reasonable?

The planting density of jujube trees is very closely related to early fruiting and high yield. Generally speaking, the greater the density, the easier it is to achieve early fruiting and high yield. But the greater the density, the more seedlings are needed, the higher the cost of establishing the orchard, the higher the requirements for cultivation techniques, and the more labor-intensive the management. For general cultivation, a plant-to-row spacing of 3 to 4 m × 3 to 4 m is suitable, that is, 41 to 64 trees per mu. For varieties with strong early-fruiting ability, whose current-year shoots can bear fruit, and which have weak growth and bear fruit relatively late, appropriate close planting can be carried out.
