1. Soil: loose soil with good drainage should be used for planting chestnut trees. Too sticky soil will affect its growth to a certain extent and cause root rot.

2. Watering: A lot of water will be lost after harvesting, and it is prone to drought in autumn and winter, so water it in time to ensure the water it needs.

3. illumination: chestnut trees should receive sufficient illumination during their growth, which can promote photosynthesis. If they receive insufficient illumination, the yield will be affected.

4. Temperature: If it is given a growth environment of 1-2℃, it will suffer from freezing damage if the temperature is too low in winter, and it will easily grow poorly if the temperature is not too high in summer.

5. sowing and propagation: sowing is usually carried out in March-April. Before sowing, the seeds should be sterilized with thiophanate methyl solution, suitable soil should be prepared, and the seeds can be sown in it. After planting, you can apply some Bikagan Congcong.

6. Grafting propagation: Generally, grafting is the best in August-October. Splitting is carried out 2 days before germination, and leaves are spread on the new shoots. After infusion, grafting is carried out about 2 days after germination of the new shoots. It is best to tie it tightly with plastic film after grafting, which can reduce water evaporation.
