Embodiment Construction

[0021] Below in conjunction with embodiment, the present invention is described in further detail.

[0022] The cutting propagation method of Huangzi berberis comprises the following steps:

[0023] (1) Select a transplanting site with loose, fertile, slightly acidic to slightly alkaline soil. If the soil is clay and the fertility is insufficient, soil improvement must be carried out in advance. Apply 3000 kg of decomposed organic fertilizer and 50 kg of phosphorus fertilizer per mu as base fertilizer, and apply 2 kg of insecticide carbofuran to control underground pests. As above, no dead corners are left in the field, and then rake it once to level the bed surface, open side ditch around the field with a depth of 50-80cm and a width of 60cm, and open a middle ditch in the center of the field to communicate with the side ditch with a depth of 40- 60cm, width 50-60cm; make a bed, the width of the bed surface is 110cm, the soil block on the bed surface is thin, the center is s...
