The effects of temperature （day temperature 23～25qC ，night temperature 10～13‰ ）andenvironmental factors such asrelative humidity （60 % ～65 % ） and CO2 concentration （600～800μmol/mol） ）onthe physiological and biochemical characteristics of asparagus were studied. The resultsshowed thatunder thefacilityenvironment，therelative water content of asparagus leaves increased by 18.6% ，the osmotic regulating substance proline content decreased by 25.3% ，and the photosynthetic rate increased by 22.5% .Theroot activity increased by 25.1% ，and theyield increased by 41.3% compared with the open field. The research results can provide theoretical basisand technical reference for alleviating drought stress in protectedcultivation of asparagus in Yinchuan.

银川地区具有典型的中温带大陆性气候特征，年均日照时间 2800～3100h ，年降水量仅 180～200mm ，而年蒸发量高达 1600～1800mm ，春季多风沙，昼夜温差大，这些环境因素严重制约着芦笋的种植发展。（剩余6162字）
