Seed sowing of Luohan pine

Before sowing, the seeds need to be soaked in warm and cold boiled water for about 4 days to fully absorb water, which is conducive to improving the germination rate. The row spacing of sowing plants is 10x20cm, the depth is better to cover the seeds, and then cover the grass to moisturize. Spray water once a day after sowing, and the grass cover can be removed after about 8 days. In addition, avoid exposure to the sun and do a good job of shading

Seedling raising techniques of Pinus grosvenorii

Generally, seeds can germinate about 40 days after sowing. Pay attention to the spacing between seedlings. If it is too dense, the seedlings can be transplanted with soil in the empty place. In addition, it is necessary to avoid watering the newborn seedlings to ensure the survival rate of seedlings. When the seedlings grow about 6 leaves, you can properly drench some biogas dilution water. It is best not to use chemical fertilizer. The seedlings grow slowly, so they can be transplanted after one year. The plant spacing and row spacing are 20 cm, or they can be moved to the nutrition bag with one plant in each bag. One year later, it will be transplanted again. After three years of seedling raising, the seedling height can reach 1-1.3 meters, the crown width can reach 1 square meter, and the tree crown forms a tower shape, which can be used for gardens or continue to grow large seedlings.
