Over the years, we planted the mountain camphor (sweet potato), outside the county to buy seedlings; Zhongshan plankton, low mountain to buy seedlings; collective planted, free market to buy seedlings, resulting in late planting and low yield, waste a lot of manpower and financial resources and improve Cost of production. In order to change this passive situation and promote the rapid development of agriculture, the vast majority of poor and middle-level peasants and scientific and technological personnel in our county learn the experience of raising nurseries in the field and use the solar thermal storage bed to cultivate strong seedlings and obtain better results. What is a solar thermal storage bed? The solar thermal storage bed is a seedbed that is covered with a plastic film. It is the use of sunlight through the film, raising the temperature inside the bed, so hot air
