摘　　要：2014-2015年连续2年对浙南山区东魁杨梅进行采收前25、35、45d罗幔处理试验。结果表明，罗幔各处理对东魁杨梅果蝇的相对防效达86．83％以上。在杨梅采收前的25～45d罗幔范围内，果蝇相对防效随着罗幔时间的增长而增大，商品果率和优质果糖度随着罗幔时间的增长而降低。采收前35d罗幔处理的单株杨梅产量和效益最高，分别为20．1kg和516．7元，综合考虑商品果率、糖度和果蝇防效等因素，建议在山区东魁杨梅栽培中推广应用采收前35d罗幔技术。By hanging curtains in different picking times, Dongkui tree was treated in mountainous area, the south of Zhejiang Province in 2014 - 2015.It was shown that the LuoMan that had good antagonism against fruit flies was above 86.83%. Before the harvest of 25 - 45 days curtain range, the occurrence of flies was increases with the growth of the different LuoMan Curtain Time. Meanwhile, the commodity fruit rate and quality of fructose was decreased. It makes the fruit yield, quality and benefit best, after LuoMan processing 35 days, 20. lkg and 516.7 Yuan respectively. Considering all factors, taking 35days Luoman Curtain Time is suggested in popularization and application of Dongkui Tree planting.
