1, time. Usually in September-September, when the shoots are ripe, or after the spring shoots are sprouted before the spring shoots. 2, density. Planting was carried out at a planting density of 4m from a row spacing of 3m, and 55-60 plants per mu were planted. 3, planting technology. Soil digging planting points: pull wire distance, dig and planting hole, hole depth, width 80cm, then press green fertilizer 50cm deep, backfill 40cm high planting; Tianqi Lung planting: 8 meters with ditch (ditch width 60-80?, deep 40-60cm) open car, each car from 2 ridges (ridge width 1.5m, ridge center distance 4m, ridge height 20-30cm). When planting, the roots of seedlings will be trimmed moderately and then put into the center of the planting hole to stretch the root system, support the right direction, and gently raise the seedlings while filling the soil. This makes the root system and the soil closely connected. Pour enough root water, make a 1m round tree disk around the seedlings, and cover it with a clam shell.
