First, there are two ways to cultivate seedlings. One is to dip deep in the jujube garden near the jujube tree, cut off the surface roots, and promote rooting. The second is that during March-April, choose a robust jujube garden, 2 to 3 meters from the base of the trunk, dig deep 40 to 50 centimeters, and 25 to 30 centimeters wide long groove, cut fine roots, and ditch the wall flat Straight, to facilitate fracture healing, in May can produce root cause. When the seedlings reach a height of about 30 cm, the seedlings will begin to grow weakly, leave the distance, and seal the soil. The thickness is 1/3 of the seedling height. Combine irrigation and fertilization to promote new root and seedling growth.
Second, the cultivation of wild jujube seedlings
1. Collection and treatment of seeds In late October, collect sufficient and mature fruits, rinse with water, rinse skin and floating nuclei, and timely sow in autumn. Seeds sown in time must be treated to break the dormancy and ensure seedlings.
2. Sowing and seedling management sowing time is generally in late March, sowing the nursery should apply enough base fertilizer, irrigation water, deep turn for the rake, detailed land preparation. Generally wide and narrow row sowing, wide line 40 to 50 centimeters, narrow line 30 centimeters, sowing 4 lines per plant, sowing 10 to 15 kilograms per acre, covering soil 3 cm compaction, and sprinkle a layer of fine sand on it to facilitate Warming up the seedlings, finally covering the film on it.
10 to 15 days after sowing. In late April, when the seedling height was 5 cm, the seedlings were filmed in time. Before the wheat is harvested, the seedlings are planted at a spacing of 15-20 cm. The water source is watered at the beginning of June and the water is sprayed every 20 days. Irrigation topdressing urea 10 to 15 kg per acre. When the seedlings were thicker than 0.4 cm in the year, they could be grafted out of the nursery in the coming year.
