Fertilization is an important guarantee to ensure the healthy growth，yield improvement and high quality of tea trees. Single application of inorganic fertilizer or organic fertilizer can promote the yield of tea，tea product quality and soil fertility，but there are obvious defects and hidden dangers，such as soil acidification，serious nitrogen loss and reduced yield of fresh tea leaves. Therefore，inorganic fertilizer and organic fertilizer application，combining with new type of fertilizer and new fertilization technology system，such as selenium fertilizer，carbon-based water-soluble fertilizer and intelligent water and fertilizer integration，is an important way for the sustainable development of tea garden. In this study，the effects of three fertilization modes of inorganic fertilizer，organic fertilizer，inorganic fertilizer combined with organic fertilizer on tea plant growth and development，tea production，tea quality and soil fertility were summarized. Considering with new type fertilizers and fertilization technology in tea garden，this paper put forward relevant development suggestions from multiple aspects，so as to provide reference for realizing rational fertilization in tea plantations，producing high-yield and high-quality tea and improving soil quality in tea production. It provides research ideas for rational fertilization，production of high-yield and high-quality tea and improvement of soil fertility in tea garden in the future.
