It is best to choose acidic sandy loam or loam with good drainage and aeration, deep and loose soil, and convenient drainage and irrigation.

2. Land preparation and bed making

Before sowing, the seedling site should be deeply plowed and leveled, and base fertilizer, compost and other organic fertilizers should be applied. While fertilizing, ferrous sulfate (15 kg per mu) can be mixed in for soil disinfection.

3. Seed treatment

Before sowing, the seeds should be disinfected by soaking them in a 0.15% formaldehyde solution for 15-30 minutes, or in a 0.59% potassium permanganate solution for 2 hours. Then soak the seeds in 40-60 degree warm water for 1 day and night, take them out, put them in a container and place them in a warm place for germination. When one third of the seeds have split open, they can be sown.

4. Sowing and seedling raising

The sowing period is from April to May, with a sowing rate of 15-20 kg per mu, row spacing for drilling of 20-20 cm, sowing width of 7-10 cm, and a soil covering thickness of about 1 cm, then press down lightly.

5. Seedling stage management

After pine seeds are sown and germinate and emerge, according to the growth habits of the seedlings, promptly carry out drought resistance and drainage, pest and disease prevention and control, and timely topdressing, loosening soil and weeding management. Before the seed shells fall off, pay attention to preventing bird damage. Seedlings should be appropriately dense, and during the growth period damping-off disease should be reasonably controlled; at the same time, fertilize reasonably, mainly with nitrogen fertilizer in the early stage, and with phosphorus and potassium fertilizer in the later stage.
