Anenvironmental automatic regulation deviceof wax apple cultivation is disclosed. Theenvironmental automatic regulation deviceof wax apple cultivation is disposed in atransparent structure, and comprises a temperature and humidity control module, a light regulating module for control the light availability, a soil temperature and humidity control module for regulating the temperature and humidity of the soil in the structure, a temperature increasing module, and a central control unit which electricity couples with those modules to regulate and to keep the microclimate inside the structure steady so as to get longer harvest and better quality of wax apples cultivated in the structure.本案為一種蓮霧栽培環境自動調控系統,設置於可透光設施中,至少包括:溫濕度控制模組、日照調控模組以調控日照時間之長短、土壤溫濕度控制模組以控制設施內土壤之溫濕度、燃油增溫模組,以及中央控制單元,其係與溫濕度控制模組、日照調控模組以及土壤溫濕度控制模組電連接,透過溫濕度控制模組及燃油增溫模組以維持設施中之溫濕度,藉由溫濕度控制模組、日照調控模組以及土壤溫濕度控制模組之間的環境調控使設施內部環境條件維持穩定,以利栽植於設施內之蓮霧果樹全年度生長、繁殖,俾延長蓮霧之產期及提升產量。1‧‧‧蓮霧栽培環境自動調控系統10‧‧‧設施11‧‧‧中央控制單元12‧‧‧內循環模組13‧‧‧溫濕度控制模組14‧‧‧日照調控模組15‧‧‧土壤溫濕度控制模組16‧‧‧燃油增溫模組17‧‧‧控制室
