中文摘要 | 本試驗以「玉荷包」荔枝著果後55 d之果實,以不同套袋材質包括網袋、半白袋、全白袋、黃袋與黑袋在樹上進行套袋處理,以慣行農藥防治法為對照組,欲找出提升「玉荷包」荔枝品質與食用安全之栽培模式。結果顯示,使用各種紙質套袋皆顯著增加荔枝果皮花青素含量,使用黃色套袋與黑色套袋則會顯著降低葉綠素含量。各種套袋防治處理皆可顯著減少落果率,並減緩果實生長速度,使果重較輕。農藥殘留檢測結果顯示,於對照組有3種農藥殘留,網袋與半白袋有2種農藥微量檢出,套白袋、黃袋與黑袋則完全未被檢出。本研究結果顯示,以合適材質套袋處理可減少農藥施用次數及農藥殘留,增加荔枝果皮花青素含量,提升「玉荷包」荔枝食用安全之商品價值。 |
英文摘要 | Fruit of ‘Yu-Her-Pao’ litchi was packed on tree 55 days after fruit setting with different bagging materials to improve the pericarp color and reduce the pesticide residues. The anthocyanin content of pericarp increased in all bagging treatments. The chlorophyll content decreased in fruit packed with yellow and black bags and increased in net bag, half-white bag and white bag. The fruit drop and fruit growth reduced in all bagging treatments. Pesticide applications were stopped after fruit was bagged on tree. The pesticide residues were significantly reduced by bagging treatments. Three kinds of pesticides were detected in control. Two of them were detected with lower levels in fruit packed with net bag and half-white bag. None were detected in other bagging materials including white bag, yellow bag, and black bag. The results of this study indicated that bagging the fruit on tree with suitable bagging materials can increase pericarp anthocyanin content and effectively reduce pesticide application and residues. |
