1, pitaya management is relatively simple, but it is not cold-resistant, so the greenhouse needs two layers of shed and two layers of film. The temperature should not be lower than 5 degrees Celsius, and it will freeze to death below 5 degrees Celsius.

2. Besides controlling temperature, water quantity is also an important factor to determine whether pitaya can grow normally. Water should not be too much, it is a dry land crop, and the ditch on the side should be dug deeper before being discharged.

3. Pitaya is very adaptable, regardless of soil quality. It can be planted in an environment where the temperature is lower than 8℃ for a short time, and can be put indoors for wintering in places with low winter temperature in the north.
