摘要

本研究具有節能減碳的功能，運送適量的肥料與灌溉水到作物根部區域，提供作物生長所需，減少肥料與水資源浪費。採用養液即時注入式之養液自動化輸送管理系統，4種養液藉由幫浦即時注入送水管路，經過過濾器直達田區，經試驗，主管路幫浦流量約195 l/min，養液幫浦流量約0.5~5 l/min，不同養液輸出百分比於各養液管路流量之標準差均在0.35以內，本系統之年灌水量僅為傳統淹灌方式的43.4%，節省灌溉水達56%。本系統每日少量多次自動肥灌6至8次之電力消耗每天約8 kWh，調查胡瓜產量、果實性狀、葉片性狀等均在水準之上，顯示自動施肥灌溉系統能夠充分發揮省工、省水、省肥之效益。

The traditional nutrient feeding system was both time and energy inefficient in liquefying and diluting fertilizers with water at each fertigation process. The newly developed PLC type of fertigation system can manipulate the output volume of 4 nutrient injection pumps that inject nutrients into the main pipe directly. The nutrients can be mixed in the path by the following filter and pipe lines before being dripped /micro-sprayed into the plant root area. The main pipe flow rate is 195 l/min. The nutrient flow rate can be adjusted between 0.5 ~ 5 l/min, its standard deviation is under 0.35. The amount of annual irrigation water is only 43.4% compared to the traditional pond-irrigation method. The new system, operating 6 to 8 times daily, only consumes 8 kwh of power. Survey the cucumber yield, fruit and leaf characteristics are all above level. This automatic fertigation system can facilitate cucumber growth while saving labors, fertilizers and water, thus effectively saving energy and reducing carbon emissions.
