The invention discloses a multifunctional solar greenhouse. The basic structure of the multifunctional solar greenhouse is a high-specification concrete steel bar independent basic structure with the size of 0.5*0.5*0.5 cubic meters, according to the construction technology that one independent structure is designed every 1.2 meters, each independent structure is welded to a steel bar embedded part and is connected with a 2-cun steel pipe wall body independent pillar with the wall thickness of 2.7 mm and the length of 3.2 m and a 20-cm light compound wall plate, and a firm integrated structure of the basic structure, the wall body pillars and the wall plates is formed. The multifunctional solar greenhouse is good in stability, is good in integration performance, improves the overall firmness, improves the capacity of resisting wind pressure and snow pressure, guarantees safe planting and production in bad weather, is good in heat preservation performance, is good in environmental protection performance and is low in construction cost. The multifunctional solar greenhouse further has the advantages of being short in construction period, small in occupied space, convenient to move, free of construction garbage, capable of preventing breeding of plant diseases and insect pests, and the like.
