庭院温室的建造存在许多问题,其中采光角度的设计是一个主要问题。采光角度过小(低于20°),光的反射率大,室内光照不足,不利于蔬菜作物的生长发育,采光角度过大(超过30°),光的透入率虽然提高了,但保温性能差,燃料消耗过多,不利于节能和提高经济效益。本文依据科学原理,来说明温室采光角度设计的原则。 There are many problems with the construction of courtyard greenhouses, of which the design of lighting angles is a major issue. Light angle is too small (less than 20 °), the light reflectivity, inadequate indoor lighting is not conducive to the growth of vegetable crops, lighting angle is too large (more than 30 °), although the penetration rate of light increased, but insulation Poor performance, excessive fuel consumption is not conducive to energy conservation and improve economic efficiency. This article based on scientific principles, to illustrate the principle of greenhouse lighting angle design.
