Abstract: In order to screen new green manure varieties suitable for intercropping in tea gardens of Wuyi Mountain, 19 cruciferous green manure varieties were selected and the growth period, biomass, and nitrogen(N), phosphorus(P), and potassium(K）nutrients accumulation rates of these varieties were analyzed during 2022-2023 in varieties(strains）growth seasons, that intercropping in tea gardens of Wuyi Mountain. The results showed that: among the tested varieties(strains), there were nine green manure varieties(strains）with high fresh biomass and dry grass biomass, and strong NPK nutrients accumulation capabilities. These varieties(strains）including seven rapeseed (Brassica napus L.) cultivars（strains）were 557, Zhongyoufei No.1, Jinhuanghua, 21Q065, Zhonglvyou No.2, Zhongshuang No.11, and Yangguang 2009, respectively. And two rapeseed（Brassica juncea L.）varieties(strains）were Yuanjie 001 and Zijie J082, respectively. Other than that, there were two green manure varieties(strains), rapeseed（Brassia campestris L.）cultivar Zhonglvyou No.1, and radish（Raphanus sativus L.）strain RS007, there had a short plant height, long flowering period, medium yield of fresh biomass and dry biomass, and relatively strong NPK nutrients accumulation capabilities. These eleven varieties(strains）had strong regional adaptability and comprehensive fertilizer performance were suitable for intercropping in tea gardens of different ages, and serving the construction of high-quality and efficient ecological tea gardens in Wuyi Mountain.
