How can white orchids have the highest survival rate when they are propagated by high-altitude striping and cuttings?

① high-altitude pressing strip: from May to July, select mature and robust 2-year-old branches, peel 4mm around the pressed place, place the thin film reel at the ring peeling place, and place the ring cut in the center. Bind the lower part firmly, fill in the wet fine sand, garden soil or humus soil after exposure for 5 days, then seal the upper mouth tightly, open the upper mouth to check the rooting after 50-70 days of new leaf germination, cut off the parts when they have grown roots, and transplant them in time. When there is no root, it is still bandaged with water and cut away from the mother after taking root.

② cuttings: growth period select 1-2-year-old branches, 6-10 cm long, with a sharp knife to flatten the base, cut off the lower leaves, upper leaves cut 1-inch 1-prune 2, cuttings in sand or vermiculite after disinfection or exposure for 5-7 days, depth to stable watering does not lodge as the principle, place semi-shaded place to maintain air and soil moisture, about 50 days can take root, using heel cuttings to survive through the highest.
