Research and Development of Bio-fortification Technology for Precision Hydroponics

Untitled 956 x 1080 px 956 x 1280 px

Project Objectives

  • To address local nutrient deficiencies in calcium, iron, and iodine by building upon PolyU’s patented technology. Through an indoor, controlled-environment hydroponics platform, we aim to further develop efficient bio-fortification techniques, focusing on the effects of different chemical forms and concentrations of calcium, iron, and iodine on commonly consumed salad greens and Chinese vegetables in Hong Kong.
  • To collaborate with local hydroponics businesses to use their farms as pilot testing sites, allowing us to scale and optimize the bio-fortification technology developed in our lab. This includes establishing a mid-scale production line and creating standardized operating procedures.
  • To promote sustainable hydroponics through knowledge transfer, public education, and promotional activities. Our goal is to enhance the market competitiveness of locally grown hydroponic vegetables, foster sustainable development in the hydroponics industry, and nurture a culture of "healthy eating and sustainable living" in Hong Kong, ensuring better public health.

Activities (Launching Mid-2025)

  • Bio-Fortification Knowledge Transfer Workshops: Offering technical support and quality control testing services. 
  • Public Talks and Hydroponic Vegetable Tastings: Allowing consumers to learn about the cultivation environment and processes behind hydroponics while experiencing the quality and taste of hydroponic vegetables firsthand.

創新科技推動農業 邁向高質量可持續發展 [Chinese only]

隨着全球人口持續增長、城市化進程加快,傳統農業正面臨前所未有的挑戰。土地資源有限、氣候變化帶來的影響,以至農業過程中產生的環境污染問題,使人類需要尋找更高效、可持續的農業生產方式。水耕栽培作為新型種植技術,逐漸受到廣泛關注和應用。

水耕栽培是指在沒有土壤的情況下,透過營養液供應植物所需的養分。與傳統土壤栽培相比,水耕技術能精確調控溫度、濕度、養分和光照等種植條件,為農作物度身訂造合適和穩定的生長環境。

一直以來,本港的蔬菜供應以進口為主。現時本港約有50個水耕農場,產量僅佔本地生產蔬果總量的百分之三。雖然水耕栽培能有效及穩定地生產蔬菜,但建立水耕系統的前期投資和日常營運成本費用高昂,導致本地水耕蔬菜成本價格較高,不利於與內地進口蔬菜競爭,市民對購買水耕蔬菜的意欲亦相對薄弱,為水耕業的長遠發展帶來隱憂。


研發精準水耕生物營養強化技術

消費者越來越重視健康、崇尚天然飲食。因此透過創新科技加強水耕蔬菜的優點,提升其市場競爭力,是促進本地水耕業現代化及可持續發展的關鍵。香港理工大學未來食品研究院近年致力推動現代化農業科技,透過其負責營運、全港首個促進城市耕種的研發平台「信佳城市綠色耕種研究實驗室」,研發精準水耕生物營養強化技術,提升本地糧食生產力,並推動健康飲食與可持續生活文化。


政府一直重視本地漁農業發展,更於去年底公布《漁農業可持續發展藍圖》,循產業化的角度促進業界升級轉型、現代化及可持續發展。我們的研究團隊今年更獲漁農自然護理署可持續農業發展基金資助,以現有的專利技術為基礎,進一步研發精準水耕生物營養強化技術,於種植過程中提高蔬菜的礦物質或微量營養素含量。團隊特別針對本港市民普遍攝取不足的鈣、鐵及碘的情況,把這些微量營養素加入常食用的蔬菜,例如鶴藪白菜和沙律菜中,讓大眾透過日常飲食,方便實惠地滿足營養需求,提供針對性的天然營養補充解決方案。

具環境效益及降低成本

雖然水耕蔬菜在本港未算普及,但水耕栽培具有顯著的環境效益,被視為農業可持續發展的重要一步。

首先,水耕栽培的用水量較傳統土壤栽培大幅減少,對於水資源緊張的香港尤其重要。其次,水耕栽培的種植周期較快,亦不受氣候限制,能持續穩定產出,避過天然災害和蟲害,毋須使用農藥,減少對環境的污染。

此外,水耕栽培能充分利用縱向空間,大大節省土壤栽培所需的種植面積,生產基地可由農地轉移到面積較小、建築密度較高的城市大樓或工廈之內,不但能活化空間,亦能把原有的農地投入其他更高經濟價值的產業中,並進一步減低食品運輸過程中產生的碳排放,降低生產成本。

促進本地水耕業現代化

運用高科技推動農業可持續發展是全球的大趨勢。政府一直鼓勵農業界以可持續作業的模式應對不斷轉變的經營環境,包括發展都市農業等,以實現業界整體升級轉型,融入粵港澳大灣區的發展大局。

為全面提升本地水耕菜的市場競爭力,我們的研究團隊將與本地水耕企業合作,進一步優化精準水耕生物營養強化技術,構建生產線並制訂有關標準作業流程。團隊亦會透過舉辦技術工作坊,與本地水耕企業分享項目研究成果,提供相關技術支援及質量控制檢測服務,促進營養強化技術的知識轉移,共同促進本地水耕業現代化和可持續發展,協助產業增值。
