太阳能温床的建造:太阳能温床由贮热池、输热道、调热孔、排气囱、贮热层、营养土及覆盖塑料薄膜组成.通过塑料薄膜的太阳辐射热,除供给床间及营养土升温外,贮热池,贮热层,输热道也贮有一定热量,由于炕两端排气囱的作用,热空气不断通过输热道而循环,供贮热层吸收热量,使营养土温度升高,促进作物生长.温床具有光照好、受热均衡、气温高、土温高、温差小、可调温湿度的特点;具有建造简单、成本低廉、管理方便、易于推广的优点.
Solar hotbed construction: solar hotbed by the pool, heat pipe, heat transfer holes, exhaust stack, heat storage layer, nutrition soil and plastic film covered by the plastic film through the solar radiation heat, in addition to the provision of bed and nutrition Soil temperature, storage pool, heat storage layer, heat transfer Road also stored a certain amount of heat, due to the role of the exhaust stack at both ends of the kang, the hot air continuously through the heat transfer cycle, for the heat storage layer to absorb heat, nutrition Soil temperature is increased to promote crop growth. Hotbed has the characteristics of good lighting, balanced heating, high temperature, high soil temperature, small temperature difference and adjustable temperature and humidity. It has the advantages of simple construction, low cost, convenient management and easy popularization.
