Abstract: 河北省沙河市蝉房乡现有板栗6700hm2,其中有3067hm2已被国家农业部北京中绿华夏有机食品认证中心认证为有机板栗生产基地,该基地于2012年被河北省科技厅授予"国家太行山星火产业带板栗产业沙河科技示范基地".生产有机板栗,防治病虫害是重要环节,现将本区常见的板栗病虫害防治措施总结如下: 1 防治板栗的病害 1.1粗皮病 ①增施有机肥,提高树体抗病能力.秋季板栗采收后施腐熟的鸡粪、猪粪、羊粪和牛粪等有机质含量高的有机肥,采用沟施或穴施法,每666.7m2施入3000~5000kg.②冬季清园减少病源.结合冬剪,剪除病枝、枯枝,清除病株,带出果园集中烧毁,降低病源基数,可有效减轻病害发生.③修剪后树干涂白,用石灰、硫磺、食盐(生石灰10kg、硫磺1kg、食盐0.5kg、水40kg)配制的液体涂树干.④喷药防治.6~8月,每隔7~10天全树喷1次0.3 ~0.5°Be石硫合剂.
