地下长期蓄热太阳能蔬菜温室

地下长期蓄热太阳能蔬菜温室是不用任何辅助热源，完全依靠太阳能资源，采用太阳能供热的一种新型太阳能蔬菜温室。利用温室深层土壤在夏、秋季将太阳能蓄存，到冬季再向温室浅层土壤补充供热，提高温室浅层地温，改善温室中蔬菜作用的生长环境。

UNDERGROUND LONG-TERM HEAT-ACCUMULATED SOLAR GREENHOUSE

Underground long-term heat-accumulated solar energy greenhouse,which does not need any auxiliary heat source, and depends completely on solar energy,is a new type of greenhouse heated by solar energy.The solar energy is stoped in the deep earth of the greenhouse in summer and autumn.The stored energy can supply heat to the shallow earth in the greenhouse in winter.It will raise higher the temperature of the earth and improve the living environment of greens in the greenhouse.It is an effective way to solve the problem of low temperature of the greenhouse in arctic-alpine zone.Heat-accumulated and temperature-raising greenhouse is suitable to plant greens in early spring.Therefore,greens and seedlings can grow all the year round.
