摘　　要：首先对利用太阳能和风能的山地作物灌溉系统的构造和运行情况进行分析,然后研究其在山地茶园的应用效果.结果表明:在平均风速为4 m·s-1时,1级风力提水机结合太阳能节水灌溉控制系统,可管理4.3 hm2铁观音茶园的调亏灌溉,平均每天节省近10 k Wh电能;铁观音茶树叶片的净光合速率、蒸腾速率和气孔导度均显著高于无灌溉系统的茶树,但水分利用率显著低于无灌溉系统的茶树.The structure and operation of the upland crop irrigation system powered by wind and solar energy （UCIS-WS） were first- ly analyzed. Secondly, the UCIS-WS was applied to manage the irrigation for the tea plants in a Tieguanyin tea garden. The results showed that one UCIS-WS could automatieally manage the irrigation of 4.3 hm2 tea garden, and save 10 kWh energy every day with 4.0 m · s-1 wind. The Pn, E and Gs of tea leaves managed by UCIS-WS were significantly higher than those in control group. How- ever, WUE of tea leaves managed by UCIS-WS was significantly lower than that in control group, indicating that the tea plants were in good growing stage by using UCIS-WS.
