南江县人工核桃林鼠害防控技术

Rodents Prevention Technology in Artificial Walnut Forest in Nanjiang County

摘要: 核桃是秦巴山区农民脱贫致富的主要经济林，种植面积很大，但近年来，松鼠危害严重。2018年5月-9月，对地属秦巴山区的南江县进行了核桃鼠类调查及防控技术研究。结果显示：对核桃造成危害的鼠类有4种，即岩松鼠（Sciurotamias davidianus）、珀氏长吻松鼠（Dremomys pernyi）、红白鼯鼠（Petaurista alborufus）和灰头小鼯鼠（Petaurista caniceps）。通过行为监测分析，松鼠类在核桃林中的活动以取食和移动为主。采用化学防控方法通过自制毒饵箱进行防控布点，松鼠取食率高，防控有效。
