(2) Selection and treatment of cuttings. It is necessary to select semi-lignified branches without pests and diseases as cuttings, with 2~3 buds on each branch, 1~2 leaves on the upper part, and cut off half of the leaves. The lower incision of the cuttings should be cut flat or obliquely close to the internodes, and the incision must be smooth, and then dipped in ABT rooting powder I treatment solution.
(3) bed insertion preparation and post-insertion management. The bed should be planted in a place with good water source, with screened sand as bed soil, disinfected with zineb or potassium permanganate, and shaded with a 2-meter-high shade shed after the land is leveled. Check at any time after transplanting to keep the humidity in the shed at 90%. After 25 days, 0.2% urea or potassium dihydrogen phosphate is sprayed outside the roots to fertilize and strengthen the seedlings, and the cuttings can be transplanted for about 40 days.
