The invention relates to a hybrid hazel seedling-breeding method. A sandy loam land is chosen for breeding, and the plant and the row spacings are 0.8m to 1m multiplied by 2.2m to 2.8m. 45-angle oblique layering is carried out, the angles of seedlings are adjusted to 45 to 0 degree relative the ground according to the growth of the seedlings after sprouts emerge on the backs of the seedlings, andif the front young sprouts are higher than the rear young sprouts, then the front young sprouts are lowered, or else are raised. Meanwhile, shallow burying is adopted to treat root systems, and pinching is carried out once every ten days in late June and early July in the year of planting. Pruning and cutting are carried out to induce root shoots. After seedling-breeding seed trees are pruned, the trunks are 1m high, and thirty growing points are left over. The ratio of the lower basal young sprouts to the upper emerging young sprouts is 1:1. When basal branches are grown to 50cm to 60cm high, leaves which are less than 25cm are rooted out, so that related cuts are produced. Rusted iron wires are used for transversely constricting basal roots 1cm away from the ground, and rooting agent issprayed on the transversely constricted parts. Soil is used as seedling-raising substrate, and soil conditioner is sprayed. The seedlings are packaged in plastic films filled up with wet material andloaded into cartons. The hybrid hazel seedling-breeding method has the advantages that: a number of seedlings can be raised in a unit area, the quality is high, the oblique layering technique is advanced, the hybrid hazel seedling-breeding method is suitable for breeding in a large area, and the cost is low.
