Key points of planting and management of wood fragrance

1. Thinning

When the seedling height is 3-5cm, thin out the seedlings at a spacing of 4-6cm. When the seedling height is 6-9cm, thin out the seedlings at a spacing of 15cm. If seeding is done in holes, leave 2 healthy seedlings in each hole, and replant the missing seedlings with soil in time. Generally, about 12,000 seedlings are left per 667㎡.

2. Intertillage and weeding

Generally, weeding is done 3-4 times in the first year. The seedlings grow slowly, so weeding should be done in time and the soil should be loosened shallowly. When the seedlings grow 6-7 true leaves, weeding is done for the second time; the third and fourth times are done in July and August respectively.

3. Topdressing and soil cultivation

Apply nitrogen fertilizer in the early growth stage to promote vigorous growth of the plant. Apply more phosphorus and potassium fertilizers in the later growth stage to promote thick root growth. In the first year, nitrogen fertilizer is mainly used, with some phosphorus fertilizer applied.
