柑橘健康管理生產體系之研究

柑橘類自 3 月開花後需經6−9 個月的果實生長期方可採收，期間長且易受重要病原微生物與害蟲危害，天候正常狀況1−1.5 個月即需噴藥防治，故柑橘健康管理首重減少化學藥劑施用，並配合養分調節技術改善樹體營養狀況，在可接受的柑橘品質範圍內，提升柑橘果實品質與安全性。柑橘健康管理示範園經導入減藥管理後，平均減少 5 種藥劑施用、藥檢量亦低於安全容許量之1/10；再配合合理施肥技術，可提早轉色、成熟期較早，可溶性固形物與糖酸比亦較對照區高。此外，茂谷柑果實於高溫及高日射量之氣候條件，易發生果實日燒，本研究亦導入本所開發可保護果實日燒之長效型作物果實保護劑，其保護日燒與抗極端氣候的程度，優於農友慣行施用之碳酸鈣(混合南寶樹脂與水)，顯示具有田間應用潛力。統整柳橙、椪柑與茂谷柑之生長發育、生育及物候期、結果管理、整枝修剪、肥培及水分等栽培管理以及重要病蟲害田間為害生態資料，納入農民講習與宣導手冊內，以提供農民每月栽培管理與病蟲害管理之參考。 It blooms on March and harvests after 6 to 9 months in citrus (Citrus spp.), which suffers pathogens and pests easily during this long time. Averagely, chemicals are applied every 1 to 1.5 months. To reduce the chemical applies is the most important thing in the health management in citrus. In addition, improvingthe plant growth with plant nutrition adjustment technique is also important in the health management. After reducing 5 pesticides in application in our experiment, the fruits were all passed in pesticide detecting and the residual concentrations of pesticide were only 10% of safety tolerance. In addition, the total soluble solids and suger-acid ratio of fruits in experimental region were higher than that in control region after applying plant nutrition adjustment technique. It occurs sunburn easily on Murcott tangerine in summer time. Sunburn protective agent on fruits was developed. The effect on sunburn protect was better than traditional agents. Manual of citrus health management was published, which was including plant growth management, plant nutrition and pest management. This manual could be as the reference for farmers to produce fruits with high quality and high safty.
