The invention discloses a Chinese scholartree hard
branch cutting breeding method, and relates to the technical field of vegetative breeding in the
forestry science. The method comprises the steps of1) establishing a
cutting orchard, collecting scions in the spring, hiding in sand, in the middle of April,
cutting to 6-8 cm, sealing two ends with waxes, using Chinese scholartree seedlings as rootstocks, and building a happy cutting
orchard; 2) collecting and
processing, bundling after
branch cutting, controlling the length of the cuttings to be 8-9 cm, soaking the cuttings in NAA 300*10 6 mg / L + ABT1 200*10 6 mg / L of a solution, and soaking for 12h; 3) setting up a
germination pool, and spreading
river sand on the bottom of the
germination pool; 4) germinating, putting the cuttings vertically into the
germination pool, filling the surrounding and the upper portion of the river with sand, sprinkling water, covering a ground film, and setting a circumference fence; 5) after germination for 40 days, excavating the cuttings, and rinsing to be clean; 6) conducting field planting, ditching according to the row spacing of 30 cm*20 cm, and planting the cuttings of 5) in the ditches ina slightly inclined manner, wherein the upper end is exposed to the position 2 cm above the ground, the water is poured through, watering is conducted each 3-5d, pouring is conducted three times in arow, and the normal management is entered. The method has simple management and has the advantages of improving the breeding coefficient of the Chinese scholartree and the cutting
survival rate and reducing the cost.
