In order to save land and construction materials,raise land-use ratio, reduce cost of solar greenhouse and increasing economic benefit, a type of combining light with shade solar greenhouse was designed. For example, a garden plot with 20 solar greenhouse in the region of 40°north latitude, the type of combining light with shade can raise 35.4% of land-use ratio, increase 93% using area in greenhouse, save 50.2% building materials and reduce 32% cost than that of common solar greenhouse. This type solar greenhouse can save energy and improve environment and increase economic benefit also. It is a optimum type greenhouse for spreading in suitable area.
