设备:水肥一体化技术需要灌溉设备和施肥设备做基础。灌溉系统的设备包括水泵、过滤器、施肥设备、管道、滴头、喷头、控制器、阀门等。灌溉系统可以手工操作,也可以自动化控制,自动化控制的程度有高有低。简单的自控系统就是一个定时器,复杂的控制系统可以编制很多程序,监控作物生长的很多参数。选择设备时,要根据实际的需要,避免材料和功能的浪费。实际上任何一个灌溉系统都是根据用户的需求用市场上现有的设备组装而成。

水源工程:灌溉系统的水源有河水、井水、水库水和池塘水等。有些水源工程需要修渠引水或管道引水,有些需要挖井,有些需要建蓄水池。所有这些都需要投资。水源解决后需要加压,功率稍大的水泵都需要接380伏三相电源,电源连接的距离通常也会占去较大的成本。没有电源可以用柴油机或汽油机水泵,购买多大功率与规划的面积有关。水肥一体化设备.水质好坏又决定了过滤系统的复杂程度。含泥沙的河水、井水通常需要多级过滤,过滤器大小、种类和自动冲洗功能决定着过滤系统的成本。

种植方式:不同作物种植方式不同,会决定设备的数量。比如苹果种植的行间距比香蕉大,在用滴灌的情况下,香蕉单位面积所用滴灌管的数量是苹果的两倍多。叶菜类蔬菜种在田间用喷灌系统,种在温室用微喷系统,后者的单位面积投资显著大于前者。水肥一体化设备工程
