(1) Site selection and land preparation The seedling-raising plot should be chosen as a cool, fertile, and moist virgin wasteland or previously cultivated land, with loose, fertile sandy loam being preferable; the cultivation plot should be chosen as fallow land or secondary wasteland with deep soil layers. In mid-July, first cut down shrubs and weeds, spread them on the ground, and burn them, then deep-plow the land more than 25 cm, and let it weather and mature under the sun. Then, before planting, while preparing the land, apply 37,500 kg of decomposed stable manure per hectare and plow it into the soil as base fertilizer. Before sowing, shallow-plow once more and make raised beds 1.3 m wide, with furrow width 30 cm and bed height about 25 cm

(2) Transplanting Generally, the suitable period for transplanting is around Qingming. If too early, the seedlings are prone to damage from late frost after emergence; if too late, the seedlings have already sprouted and are easily damaged at the buds, reducing the survival rate. On the leveled and finely raked planting site, dig holes in a staggered triangular arrangement at a row spacing of 33 cm x 27 cm, with hole depth 20 cm. Then, select seedlings with a root crown diameter of 0.3-0.5 cm, plant 3 seedlings per hole arranged in a triangular pattern, and after planting, cover with soil while pressing firmly. When the soil has covered half the hole, gently lift the seedlings upward so the root system spreads out, then fill the hole with soil, apply an appropriate amount of plant ash or farmyard manure, and cover with fine soil so that it just covers the root crown of the seedlings by 2-3 cm.
