The land should be prepared two months before planting, and a small number of broad-leaved trees can be kept in the land preparation. The size of the planting hole is 50 cm x 50 cm x 40 cm. Planting density is 1350-1650 plants/ha. About 10 days before planting, the hole is backfilled with half of the topsoil and then fertilized with 100 grams of compound fertilizer and phosphorus fertilizer per hole, and mixed well, then backfilled with heart soil to a flat hole ready for planting. Planting should be done in March-April. Drench the seedlings with water before planting and strip all the bags when planting, but prevent the nutrient soil from breaking. The planting depth should be about 5 cm to cover the nutrient soil, and compact the soil around the nutrient soil. When the seedlings are taller, they can be planted deeper. Check and replenish seedlings 1 month after planting.
