Select well-drained, sheltered flat or sloping land with sandy loam, yellow loam, or brick-red loam soil. Clear shrubs and weeds, remove tree roots, then proceed with planting.
2. Propagation Methods:
Harvest mature seeds with dark brown seed coats and distinct wrinkles. Sow them in clean sand beds using the spot-sowing method, spacing seeds approximately 3 cm apart.Cover seeds with sand, then mulch the bed surface with straw. Water thoroughly and maintain bed moisture.
3. Transplanting:
Transplant in spring or autumn, preferably on cloudy or rainy days for higher survival rates.Plant at 4m × 4m spacing (41 plants per mu). Dig planting holes 50cm long, wide, and deep. Apply 15–20kg of well-rotted manure or compost per hole, mix thoroughly with topsoil, then place seedlings (removing nutrient bags) into holes. Cover with 20–30cm of soil, water thoroughly, and shade.Gradually remove shading once seedlings are established. 4. Intercropping: Native to regions where flowering and fruiting occur after 5–6 years, introduced plants require 3 years to flower. To maximize land use and economic returns, intercropping with other cash crops is advisable.During the early growth stage when branching is sparse, intercrop with peanuts or legumes. After 4 years when branching becomes vigorous, intercrop with shade-tolerant crops like cardamom or white cardamom.
