| 摘 要： | 肥灌(Fertigation)就是通过灌溉系统为植物提供营养物质的过程。Fertigation以微灌系统为基础,典型的微灌系统由水源、首部枢纽、输配水管网、灌水器以及流量、压力控制部件和量测仪表等组成。Fertigation所用的肥料应全是水溶性的化合物或液体肥料。Fertigation能够减少水分和养分损失,降低总需水量,提高养分利用率。

| Abstract: | Fertigation is a process for providing nutrients to plants through irrigation system, which is based on microirrigation systems. In general, a typical microirrigation system consists of water source, leader key position,transporting water pipes,irrigating section and control section. The fertilizers used for fertigation should be completely soluble or be liquid. Fertigation can increase water and nutrient use efficiency by lowering water and nutrient losses. |
