摘要:小果番茄栽培期間需高灌溉水量,但臺灣降雨分佈不均和缺水,節水灌溉將變得至關重要。根系分區交替灌溉(Partial root-zone drying irrigation, PRD),或稱partial root-zoon irrigation (PRI),為一特別節水灌溉法,透過根系分區、乾濕交替誘發植物次生根生長。本研究以農友種苗股份有限公司之‘玉女’小果番茄作為試驗材料,期望找出最適合‘玉女’小果番茄的根系分區交替灌溉方法與水分含量,達到提高水分利用效率、維持或提升果實品質效果。
Abstract: Effects of partial root-zone drying irrigation on yield and quality of cherry tomato in greenhouse: Cherry tomato needs high irrigation water inputs during cultivation. Because of the uneven rainfall distribution and water shortage in Taiwan, water-saving irrigation will become essential. Partial root-zone drying irrigation (PRD) or partial root-zone irrigation (PRI), is a special water-saving irrigation method, which induces secondary root growth of plants through root-zone dividing and dry-wet alternating. This research uses cherry tomato ‘Rosada’ from Known-You Seed Co., Ltd as material, and hopes to find the method and water content of PRD which is most suitable for the ‘Rosada’ tomato to improve the water use efficiency and maintain or enhance the fruit quality.
