Its wood is characterized by its lasting fragrance, pale yellow color, aroma, dense and tough texture, resistance to warping and cracking, ease of processing, smooth surface, and beautiful grain. Nanmu is also a national second-class protected rare and endangered species, making the cultivation of Nanmu seedlings an urgent matter. However, existing cultivation methods result in weak seedling growth and low survival rates. Therefore, designing a cultivation method to improve the growth capacity of Nanmu seedlings is essential.

Then, soak the collected fruits in clean water for 2-4 hours, then rub off the skin, then rinse them in clean water and pick out any empty buds, pest-infested fruits, and unripe fruits. Then, place the selected fruits in a ventilated room to air dry. Once the water on the seed coat has disappeared, they can be sown or stored.

[0006] In step two above, a plot of land with good drainage and aeration is selected as the sowing site, and then the seedbed is prepared on the sowing site.

[0007] In step three above, when the suitable sowing time is reached, the seeds obtained in step one are soaked in a 0.3% carbendazim solution for 2-4 hours. Then, the sterilized seeds are evenly spread on the seedbed prepared in step two. Two weeks before planting the seeds in the seedbed, the seedbed is sterilized with quicklime. Then, one day before planting the seeds in the seedbed, the seedbed is sprayed with a 2g / L potassium permanganate solution for sterilization. After sowing, fine sand is evenly spread on the seedbed to a thickness of 1-1.5 times the thickness of the seeds.

[0008] In the above step four, a shading net is arranged on the seedbed, and the distance between the shading net and the seeds planted on the seedbed is 50-60 cm, and the seedbed needs to be regularly sprayed with water to keep it moist for 7-8 days after the seeds are planted;

[0009] In the above step five, after a certain period of time, when the seedlings grow 2-3 true leaves, they are removed in batches, and the seedlings after removal contain a certain amount of soil on the seedbed, and then the seedlings are tied with a woven net woven with rice straw or wheat straw;

[0010] In the above step six, the bottom of the woven net containing the seedlings is sprayed with rooting agent, and the rooting agent is prepared by mixing indole-3-butyric acid and water in a mass ratio of 1:100, then the hole is dug, then 40-50g of rice hull ash is placed in the planting hole, then the rooting agent is sprayed in the planting hole, and the content of the rooting agent sprayed in each planting hole is 50-60ml, then the seedlings are placed in the planting hole, and the woven net is buried with soil, while the woven net is left exposed to the surface with a height of 1-2cm, then the seedlings are cultivated according to the conventional method.

[0011] Preferably, in the step two, the width of the seedbed is 1.1-1.3m, the height of the seedbed in mountain soil is 15-20cm, the height of the seedbed in field soil is 18-25cm, and the width of the path between adjacent seedbeds is 22-28cm.

[0012] Preferably, in the step three, the amount of seeds planted on the seedbed is 0.25-0.35kg / m 2 .

[0013] Preferably, in the step four, the water content of the seedbed is 50-70%.

[0014] Preferably, in the step five, the woven net is woven from rice straw or wheat straw, and the thickness of the woven net is 0.3-0.6cm, and the light transmittance of the woven net is 35-45%.

[0015] Preferably, in the step six, the seedlings are planted every 6-7 days with water-soluble nitrogen fertilizer, and the amount of water-soluble nitrogen fertilizer sprayed is 200-400ml / m 2 .

[0016] Compared with the prior art, the method for improving the growth ability of Phoebe bournei seedlings has the advantages that the seedling residual soil is wrapped with rice straw or wheat straw, the existing wrapping method using nutrient bags is changed, the nutrients required by the seedlings are provided by the netting corrosion, the growth of the seedling roots is facilitated, the survival rate of the seedlings after transplanting is improved, the growth ability of the seedlings is improved, and the planting hole is sterilized with lime and potassium permanganate solution before the seedlings are planted, so that the seedlings grow healthily.
