1, cutting cuttings. According to the length of the species, determine the number of cuttings per seed. Generally only the length of the cut 2/3 cut cuttings, cuttings each length of 18-20 cm, 1.5 cm from the top to have a bud.

Cut the cuttings in time for sand storage, in the vicinity of nursery selection elevations, drainage convenience, sunny, leeward, dug deep 1 m, 1.5 m wide, 5 m long pit. At the bottom of the pit first shop a layer of 3-4 cm thick sand, and then put a kind of bar, the bar to be erected, Pai Tight, without leaving gaps, planted over the top 10 cm thick wet sand, The four corners of the pit planted four bunches of aerated grass, and the pit was sealed until it was about 30 cm above the ground. The aeration grass was about to reveal the ground. According to changes in the climate, pay attention to observe the temperature of the soil conditions in the pit, appropriate addition of soil and earth, so as not to breed because of the temperature is too moldy.
