The results showed that environmental factors such as temperature, humidity and CO_2 in a closed greenhouse, were far higher than those in a conventional greenhouse. Compared with tomato and cowpea, spinach and alfalfa adapted well to high temperature and high humidity, and their water requirement and water use efficiency in the closed greenhouse were higher than those in the conventional greenhouse.展开更多
