Using abundant natural resources in karst areas to develop chicken rearing in tea gardens can not only make full use of natural resources and alleviate the contradiction between development and governance in rocky desertification areas but also produce good quality chicken. In this paper,the comprehensive management measures related to chicken farming in tea gardens in karst region were elaborated,in order to provided certain guiding significance for practical production.展开更多
