[0002] A greenhouse, also known as a hothouse, refers to a room with facilities such as cold protection, heating and light transmission, which is used to cultivate thermophilic plants in winter. It can provide a growth period and increase yield in seasons that are not suitable for plant growth. It is mostly used for the cultivation or seedling cultivation of thermophilic vegetables, flowers, trees and other plants in low temperature seasons. It is a building that can control or partially control the growth environment of plants. It is mainly used for non-seasonal or non-regional plant cultivation, scientific research, generation breeding and ornamental plant cultivation.
