Disclosed is a tea plantation breeding method by branch layering instead of shaping and pruning of tea trees. According to the tea plantation breeding method, in new tea plantations, shaping and pruning special for young tea seedlings is omitted, the young tea seedlings needed to be shaped and pruned are covered with handling bags and are subjected to the process of topping; the method is easy andrapid in operation; side branches of young tea seedlings can expand and be shaped, and the tea branches covered with the handling bags can grow into seedlings in next spring and summer. Plant expansion of the tea plantations can be carried out after growing of tea seedlings, so that tea seedling input cost for prior period of building of the tea plantations is saved; with forming of the tea plantations gradually, risks of disconnection of management technology, processing technology, marketing management and the like due to excessive one-time input and skip expanding of tea plantation area inearly stage of development of the tea production enterprises are reduced.
