Generally, the soil is prepared and turned deeply in autumn and winter, and the soil is turned over again after thawing in spring to clean up the impurities in the soil and cover it with a layer of organic fertilizer or farm manure as base fertilizer. After sprinkling the base fertilizer, turn the soil again, turn the base fertilizer into the soil and flatten it out to make a border. The width of the border is generally about one meter to 1.5 meters, and the height of the border is about 10 to 15 centimeters.

2. Methods of reproduction

There are three propagation methods of Magnolia officinalis, which are seed propagation, striping propagation and cutting propagation. But at present, the techniques of striping propagation and cutting propagation are not perfect, and the most commonly used method is seed propagation. The time of sowing is usually from the end of February to the middle of March every year. Soak the seeds with water for about one or two days before sowing, then soak them with strong tea for another one or two days. After the seeds are treated, they will be sown by strip sowing, with a row spacing of about 25 to 30 centimeters and a plant spacing of about five to ten centimeters.

The final planting density plant spacing is about four to five meters, and the row spacing is about six to eight meters.

4. Post-management

When Magnolia officinalis was still a seedling, we should often carry out intermediate ploughing and weeding to enhance soil permeability and reduce nutrient consumption, and we also need to build a shade. It is necessary to apply fertilizer at least once or twice a year, each time combined with watering, but also pay attention to drainage, in order to avoid rotting roots when there is more rain. At least twice a year, weeding should be carried out, and soil cultivation and loosening should be carried out more than five times a year. Topdressing is mainly based on farm manure, and the branches and leaves of Magnolia officinalis should be trimmed timely to promote its growth and keep the trunk straight.

Root rot and blight are generally caused by improper management in the field. The seeds can be soaked in Bordeaux solution, antibacterial agent EC or carbendazim or carbendazim, respectively.
