Abstract Abstract：Based on the relevant research data collected from 85 strawberry grower households in 6 majorproducing areas of Beijing，the paper analyzed the irrigation water source，irrigation facilities，irrigationmanagement and application of water and fertilizer integrated technology．The results showed that the pHvalue of all irrigation water was greater than 7.0，and EC value was mainly 0.5-0.7 mS · cm-1，accounting for50%．All respondents adopted the water-saving irrigation technology，and usage rate of drip irrigation wasthe highest，accounting for 92.9%．The key impact factors for irrigation decision-making were soil moisturecontent（94.1%），weather conditions（63.5%），personal experience（58.8%），soil texture（42.4%），andsynchronization with other grower households（3.5%）．The average irrigation quantity in substrate cultureduring the whole strawberry growth period was greater than that in soil cultivation． They were 4 479 m3 · hm-2and 2 070.0 m3 · hm-2，respectively．There were various kinds of fertilization equipment，mainly includingVenturi fertilizer applicator（40.0%），electric sprayer（28.2%），pressure differential fertilizer pot（21.2%），fertilizer injection pump（17.7%），and water fertilizer integrated machine（11.8%）．Finally，this paper putforward some suggestions directing at water-saving facilities，irrigation system and technical training．
