The cutting bed seedbeds should be prepared for dry land with high topography, loose soil and water retention capacity. After the land is ploughed, the seedbed is laid to a width of about 1m and height 25cm. A bed of river sand is mixed, and 1% to 0.5% potassium permanganate is used to disinfect the soil 1 to 2 times.
Twig Cuttings Around the middle or late June, the semi-lignified shoots of the year were selected and cut into 2 to 3 section cuttings. About 1 to 2 centimeters from the upper end of the bud is cut flat, leaving 1 or 1/2 leaves, and the lower end of the bud cuts obliquely under the joint. The base of the cutting was treated with 2000 ppm to 5000 ppm of butyric acid or naphthalene acetic acid for 3 to 4 hours, inserted into the bed at an interval of 1015 cm, compacted around the cutting, and poured with water.
Hardwood cuttings are generally carried out after defoliation and during dormancy, before the injures of December to March of the following year. Select lignified shoots with robust growth and stem diameter of 0.4-0.8 cm. Cut them into cuttings with 2 or 3 buds. The upper and lower incisions should be smooth. The upper cuts should be cut 1-2 cm away from the buds and cut. After the wax seal. The base was immersed in a 5,000 ppm butyric acid solution for 5 minutes and then inserted into the seedbed.
After the management of cuttings after cuttings, it is necessary to pay attention to cover the shade, in order to facilitate water, sun protection, rain, wind, and control the light in the bed. When the new shoot grows to 5 centimeters in length, leaves 3 to 4 leaves to pick up the heart in time to control the growth of the ground and promote rooting. After the seedlings grow to 10 to 15 centimeters, they gradually strengthen the control of grass and fertilization.
