摘要

經五年的測試，臺中區農業改良場已完成一種底部以營養液流灌及頂部以清水滴灌的介質水耕式果菜栽培系統；本套介質水耕式果菜栽培系統係結合本場既有的動態浮根式水耕系統、8吋栽培盆、本土有機介質及自製簡易滴灌管，使果菜類蔬菜的上位根系生長於8吋栽培盆之介質中而下位根系則伸展於栽培床中。如此之設計，誘使果菜類蔬菜之下位根系從事養份吸收而上位根系則進行水份之供給。經實際試種結果顯示此設計特別適合夏季果菜類蔬菜之生產，可比養液水耕法及介質槽耕滴灌法較為節能(減少3.9~64.4KW/1000M^2,作)、省肥(減少水肥污染(21.6/1000M^2,作漏排遺)及增產10~20%。

By five years of experiment, a novel design of hydro-substrate culture system special for fruity vegetable cultivation was developed by Taichung district Agricultural Research and Extension Station in 2017. This set of hydro-substrate-culture system were combined Dynamic Root Floating Hydroponic System, 8 inches cultivation pot, local organic media and the homemade simple drip irrigation tube to induce the upper root fruity vegetable to grow in 8 inches cultivation pot and the lower part of root system to stretch in the cultivation tray. Such a design, tempting to force the lower root system of fruity vegetables becoming nutri-root to the nutrient absorption and the upper root system to supply of water only. By a 5-year actual trial, the results show that this system is well-suited for the summer production of fruity vegetables. The effort is better than its grows in both liquid hydroponics and substrate tray drip irrigation farming method via more energy efficient (saving3.9~64.4KW/1000M2,crop), fertilizer (reducing liquid fertilizer pollution (21.6/1000M2,crop) and increase10~20% fruit y yield/crop.
