Accelerating germination is the basic requirement of potted maple seeds. Seeds can be harvested after the fruits are ripe, dried in the sun for about 3-5 days after harvesting, washed once with clear water, and treated with low-temperature stratification after removing surface impurities to accelerate germination. The stratification temperature is controlled at about 0-65438 00℃, and it usually takes 40 days to germinate.

2. Soil preparation

When potted maple trees, the flowerpots should be mainly pottery pots, and the slightly acidic sandy soil with good porosity and strong water permeability should be selected. Appropriate amount of organic fertilizer and compound fertilizer should be applied before sowing to prevent the harm of pests and diseases, and appropriate amount of ferrous sulfate and phoxim should be applied, followed by full stirring and deep ploughing.

3. Planting and planting

Water thoroughly before sowing to keep the sand wet. After sowing, the germinated seedlings should be buried in the soil and covered with fine soil of about 0.5 cm. In order to improve the low temperature and make the seedlings grow orderly, a plastic film can be covered on it, and ventilation should be paid attention to after covering. When the temperature is higher than 30℃ at noon, it should be shaded appropriately.

4. Post-planting management

Before the real leaves grow, they should be placed in the shade. After 3-5 pairs of true leaves grow, remove the plastic film and carry out full illumination treatment. The initial growth is slow, so it is necessary to water the soil frequently to keep it moist, and weed and loosen the soil. When the seedling height is 5 cm, it should be transplanted to promote the growth and development of root seedlings.
