| 摘 要： | 综合采用多种传感器、嵌入式系统、LoRa、计算机技术设计实现了果园物联网系统,满足一般的果园环境参数采集监测和智能灌溉,实现了果品品质改善功能,即在6—8月果熟期的夜间特定时间段弥撒16℃低温水雾,降低果园夜间的环境温度,减弱果树的呼吸作用,促进水果有机物积累和糖分转换,并在合作桃园进行了验证试验.试验表明:当日温度为37℃～28℃的情况下,将果园夜间温度降低到17℃,昼夜温差达20℃,降温效果显著.

| Abstract: | A variety of sensors,embedded systems,LoRa wireless technology and computer are comprehensively used to realize an orchard IoT( Internet of Things),which meet the general orchard environment parameter acquisting,monitoring and intelligent irrigation,especially improve the fruit quality by reducing the orchard night temperature when spraying the constant 16 ℃ well water mist in fruit ripening period from June to August,so that the respiration of fruit trees were weakened,the organic matter accumulation was promoted and the fruit sugar was increased. The verified experiment was done in an amygdalus persical orchard. The results showed that the orchard night temperature was reduced down to 17 ℃,and the broadcast wheather temperature was 37 ℃ ～ 28 ℃,the diurnal temperature difference was about,cooling effect was remarkable. |
