Abstract
一种无花果腐烂病预防法，在无花果进入半成熟期前夕，用单丝直径为0.3～0.5mm，孔眼尺寸为5mm的塑料网覆盖无花果树树冠，并将塑料网的周边收拢结扎于树干上，由于隔断了瓜实蝇在无花果上产卵的通道，从而避免无花果腐烂病的发生。
Description
技术领域
本发明涉及无花果病虫害防治技术、特别涉及无花果腐烂病的预防方法。
背景技术
近年来，一种奇怪的无花果腐烂病严重威胁着无花果果园。当无花果进入半成熟期后，会陆续发现一些果实不再膨大，表皮颜色黯淡，迟迟进不了完全成熟状态，接着果实表皮开始破溃、落果。针对这种现象，人们一直误以为是夏季高温高湿造成的霉烂病，其实，即使久不下雨，这种腐烂病并无减轻。经撕开病果仔细观察，发现果肉中有一些蠕动的小虫，在放大镜下，其形态极象蛆。再经长时间观察树上的果实，发现偶有昆虫飞到无花果上叮食果皮，将其捕获后仔细观察，原来竟是瓜实蝇。众所周知，瓜实蝇都是专门危害瓜类的，没想到，这个物种经长期进化，突然发现无花果乃是它们最好的产卵场所！对付这种瓜实蝇，喷洒农药肯定不行，因为无花果果皮既嫩又薄、喷洒药物会造成严重的农药残留，但是不使用药物却无更好的办法对付它。
发明内容
本发明的目的是提供一种无花果腐烂病预防法，以避免无花果果园的巨大损失。
本发明的目的是这样实现的：在无花果进入半成熟期前夕，用塑料网覆盖无花果树树冠，构成塑料网的网丝直径为0.3～0.5mm，网的孔眼尺寸为5mm，并将塑料网的周边收扰结扎于树干上。
采用上述方案能收到如下显著效果：
1、由于塑料网的阻隔，加之无花果树叶叶柄的支撑，使处于叶腋处的无花果不再成为瓜实蝇的产卵场所，从而从源头上消除了无花果的腐烂病。
2、本方案使用的塑料网既能阻隔瓜实蝇，又能最大限度地保留必要的透光、透气性能。
3、本方案由于去掉了瓜实蝇一个重要的产卵场所，大幅度减少了瓜实蝇的繁殖量，这将大大减轻其对附近瓜类蔬菜的危害。
