Abstract： To screen out suitable green manure varieties for tea gardens in southern Shaanxi，an experiment was conducted to compare six green manure varieties -Lolium perenne （LP），Vicia vilosa（VR），Astragalus sinicus L.（AS），Vicia sativa L. （VS），Vulpia myuros （VM），and Lathyrus cicera（LC）—in terms of fresh biomass yield，nutrient composition，plant height，and their effects on temperature，humidity，and weed control. The results showed that during peak flowering，fresh biomass yield ranked as follows ： LP > AS > VS > LC > VR > VM.LP exhibited the highest fresh biomass yield at ，significantly exceeding other varieties by 8 5 . 4 6 % to 2 3 6 . 2 5 % . Analysis of total nitrogen，phosphorus，and potassium accumulation showed that LP，AS， and VS had significantly higher content than other varieties，withLPcontributing 2O8.67kg/hm2，72.98kg/hm2， and per hectare when incorporated during vigorous growth. Compared with the clean - tilld control，green manure intercropping significantly reduced weed density in tea rows by 77.18% ～ 9 5 . 0 4 % ，with weed control effect ranked as LP > VM > VS > AS > LC > VR. Additionally，green manure intercropping improved the microclimate of tea gardens，with LP having the most pronounced effect on surface temperature and humidity regulation，follwed by VS and VM. Based on these results，LP，VM，VS，and AS are recommended forap plication in tea gardens in southern Shaanxi.
