摘　　要：为满足基础条件受限的伴矿景天(Sedum plumbizincicola)育苗棚温湿度调节和水肥药一体化灌溉需求,以湖南省湘潭市某38 m´8 m伴矿景天育苗棚为例,基于220 V电源和溪沟地表水源,选用JET1800A型喷射自吸泵、4排2组倒挂微喷喷头、1.2 m^(3)肥水罐、45 L药剂罐,并优化管路阀门实现了多功能集成,设计了一套水肥药一体化微喷灌系统。结果表明,有效长度1 m的ϕ120中空耐压型塑料盲沟满足3.3 m^(3)/h的一体化取水净水要求;2 L气压罐可满足控制需求,水泵启动不超过4.5次/h。该系统运行良好,流量、压力和精度基本符合预期。In order to meet the requirements of temperature and humidity regulation in the seedlings greenhouse with restricted conditions and the irrigation of water,fertilizer and integration,a 38 m×8 m Sedum plumbizincicola seedlings greenhouse in Hunan Province was taken as an example,220 V power supply and rivulet surface water supply,JET1800A self-priming pump,4 rows and 2 groups of inverted micro-sprinkler,1.2 m^(3) fertile-water tank,and 45 L medicament tank,the design of Piping and valves was optimized to realize multi-functional integration,and a water,fertilizer and integration microspray irrigation system was designed and put into implementation. The results showed that the ϕ120 plastic blind drain with an effective length of 1m can meet the integrated water intaking and purification requirement of m^(3)/h,eliminating the need for complex water treatment equipment;2 L pressure tank could meet the control requirements,and the pump start did not exceed 4.5 times/h. The system was running well,the rate,pressure and accuracy of water flow were basically in line with expectations.
