1. Hydroponic method

The main results are as follows: (1) A general Pei Zhu Dinghong seedling was dug up, carefully peeled off the large tiller buds formed next to the mother plant, and maintained the root system of the tiller buds. After rinsing with clean water, it was planted in a transparent container, and water was injected into 3 places of the root system, and the water was changed once every 2-5 days.

(2) in the second method, the robust soil culture Zhu Dinghong seedlings were selected, the whole plant was dug up, the rotting root system was removed, washed and disinfected with clean water, and the whole plant was planted in a transparent container and injected with clean water. The fresh water was changed once in 2-3 days, and the withered and rotten roots were removed at the same time, and water bacon could grow one after another after 1 week.

2. Maintenance guidelines

The main results are as follows: (1) the temperature and light suitable for the growth of Zhu Dinghong is 18-25 ℃, the suitable temperature for dormant period is 10-12 ℃, and the safe overwintering temperature should not be lower than 5 ℃, otherwise the growth will be inhibited. Plants below 0 ℃ are susceptible to freezing injury, so pay attention to keep warm and red red is good enough to scatter light and avoid strong direct sunlight.

(2) change the water and change the water once in 2-3 days in the initial stage and 5-7 days after half a month. It is maintained in an environment with good ventilation and bright windows.

(3) if it is only used for short-term cultivation, because the bulb contains nutrients needed for growth, it can blossom without adding nutrient solution. For long-term cultivation, nutrient solution should be added every half a month.

(4) the root rot disease is easy to occur in the prevention and control of diseases and insect pests. After it is found, the rotten roots should be removed in time, washed clean and replanted. If insect pests occur, manual capture should be the main method.
