海南槟榔叶片致黄因子调查及防控

Survey and Control of Leaf Yellowing of Arecanutin Hainan

由于近年来槟榔黄化现象不断扩散蔓延,有大量农户的槟榔树因黄化发生而减产,甚至枯死、绝收,农民增收受到严重影响。经调查,引起槟榔黄化的主要原因有:病理性因子、虫害因子及生理因子致黄等。文章对引起槟榔叶片黄化的病害、虫害及生理因子进行了综述,并提出了防控措施。

As leaf yellowing of arecanut(Areca catetus) has been spread continuously in recent years, a large number of arecanut palms have reduced their production or even died because of leaf yellowing,resulting to serious economic loss suffered by arecanut growers. A survey was made of the leaf yellowing in the areanut plantations in Baoting, Hainan in November 2018. The survey showed that the leaf yellowing of the arecanut palms was mainly caused by pathological factors, physiological factors and insects.
