龙眼果实发育期常遇病虫为害和灾害，从而引起落果、减产和品质下降。其中尤以荔枝蒂蛀虫为害普遍而严重，生产上又存在盲目防治带来农药污染的不良后果。为此，笔者自１９９６年进行龙眼果穗套袋技术探讨，现将试验结果整理如下。１材料与方法 地点选在莆田市经作良种示范繁育 Longan fruit development often encounter pests and disasters, causing fruit drop, cut and quality decline. Among them, the litchi stem borer damage is widespread and serious, and there are also adverse consequences of pesticide contamination resulting from blind control in production. To this end, the author since 1996, longan fruit bagging technology discussion, the test results are summarized below. 1 Materials and Methods Location Selected in Putian City for breeding seed demonstration
