First, regarding the planting density of red jujube, it is recommended to plant them with a spacing of 3.3 meters between trees, resulting in approximately 74 plants per acre. The best time for planting is in December when the soil is still warm and the tree can establish roots before the next growing season. Second, the planting method involves digging a planting hole that is 80 centimeters in length and 60 to 80 centimeters deep. It's important to separate the topsoil from the subsoil during excavation. At the bottom of the hole, you should place some grass or straw to improve drainage. Then, add 50 kilograms of well-decomposed farmyard manure as a middle layer. After that, mix the topsoil with compost and backfill it into the hole. The subsoil should be placed on top if possible, or fully fill with topsoil. Once the hole is filled about 30 cm above ground level, or 20 cm below the surface, water the area thoroughly so that the soil settles. Refill the hole to make it slightly higher than the surrounding ground. When planting the jujube sapling, dig a small hole of 20-30 cm in depth, place the seedling in the center, and fill the hole while gently lifting the seedling to ensure even root spread. The planting depth should match the original depth in the nursery; avoid planting too deep (which could bury the graft union) or too shallow. After planting, create a circular watering basin around the tree with a diameter of one meter, water the roots, and cover the area with a plastic sheet measuring one square meter. This helps retain moisture, maintain warmth, and suppress weed growth. While digging and planting, make sure the trees are aligned in straight lines, achieving the "three look" standard for uniformity. Third, after the saplings are established, apply fertilizer in early spring, about 10-15 days before bud break. Use 1-2 kg of urea mixed with 10 liters of water per tree. Repeat this process every other month (fertilizer irrigation), applying it 30-40 cm away from the trunk. This ensures even nutrient distribution and promotes healthy growth. Fourth, pruning is essential for shaping the tree. Remove any root sprouts and excessive branches. The main trunk should be about 1.2-1.5 cm in diameter. When the secondary branches reach 0.8 cm in thickness, cut the stem 60-80 cm above the ground, making a clean cut. Trim off any unnecessary secondary branches and select three positions to leave short cuts just above a bud, encouraging the development of lateral branches for the first primary branch. Repeat this process for the second and third primary branches. The second layer should have 2-3 main branches, and the third layer should have 1-2, with each layer spaced 70-80 cm apart. Ensure that adjacent branches are staggered to prevent overlapping. Fifth, intercropping is recommended but avoid tall or high-water-demand crops like corn or potatoes. Instead, plant legumes or green manure crops, which help enrich the soil and reduce the need for chemical fertilizers. These crops also help suppress weeds and keep the soil covered, improving overall soil health.
