近年来，山东省无棣县积极发展林下经济，推行种养结合、农牧叠加的发展模式，形成了"一镇一 品"多元化发展格局，提高了农民林业生产的积极性，为推进乡村振兴和林产业可持续发展注入强劲动 力。 在无棣县水湾镇宗王村东的一片白蜡林里，一群群体型健硕、毛色油亮的小黑猪在林间穿梭、觅 食，这里是宗王东村鲁上生态养殖专业合作社藏香猪养殖基地。据合作社负责人介绍，藏香猪养殖的经 济效益十分可观，一头成年藏香猪单头销售收入可达5000元，猪肉远销江苏、北京等地。此外，一头母 猪每年可繁殖三茬，一头2个月的小猪仔市场价格大约600元。目前，该合作社20余亩林下养殖基地，藏 香猪存栏量500余头，野藏香猪存栏量200余头，年利润在80万元以上。 棣丰街道郭家村的一块由白蜡改良的榆树和柳树林地上，每棵树上都挂有一捆捆的小树条，这是农 民自己捡拾的带金蝉卵枝条。 "每年6月~8月集中除草、挂枝和收集金蝉，省时省力"金蝉养殖户郭晓春高兴地表示，"大家都说， 这是躺着睡觉就能赚钱。" 每年6月，养殖户将自己收集好的金蝉枝条直接挂在树上，让金蝉在自然环境中完成孵化。这种完 全自然的养殖模式，第一年挂枝成活率就达到16%，比撒苗成活率提高三倍， ...
