An overview of intercropping tree/tea plantations in China Feng, Yutong
The construction of composite tea plantations allows for symbiosis and reciprocity of organisms within the tea plantation, increasing the overall benefits and enriching biodiversity. Cultivation methods that intercrop tea with other species are widespread within China. They are found throughout the provinces, and the intercropping methods vary greatly. However, no article has provided a general overview of them. This thesis is a literature review designed to summarize and analyze all the composite ecological tea gardens. Through a keyword search of all the materials in the current literature database, 223 eligible documents were selected from 10,069 relevant documents in Web of Science Core Collection, UBC Library, and Elsevier Science Direct abstracts. The possible effects of 151 different tea/other species intercropping plantations were summarized and analyzed from six aspects: contained chemical substances in tea leaves substances, microbial environment, ecological environment, multiple ecological niches, prevention of pests and diseases, and soil conditions. Moreover, it was concluded that the advantages of intercropping tea gardens outweighed the disadvantages of monoculture tea gardens. Intercropping tea gardens are more sustainable than regular tea gardens because of the changes and benefits in the above six aspects to varying degrees.
