摘　　要：[Objectives]This study was conducted to reveal the migration and distribution law of soil available nutrients in soil layer under moistube irrigation and screen out suitable fertilization modes for facility cucumber planting.[Methods]The experiment adopted the moistube irrigation mode and randomized block design.Seven treatments were set up as following:inorganic fertilizer(T 1),medium-concentration inorganic fertilizer(T 2),high-concentration inorganic fertilizer(T 3),low-concentration inorganic fertilizer+low-concentration biological organic fertilizer(T 4),low-concentration inorganic fertilizer+medium-concentration biological organic fertilizer(T 5),low-concentration inorganic fertilizer+high-concentration biological organic fertilizer(T 6)and no fertilizer control(CK).Nitrate nitrogen,available phosphorus and available potassium in soil and fruit yield and quality were determined.[Results]Under the moistube irrigation mode,the application of soluble bio-organic fertilizer combined with inorganic fertilizer could significantly increase the contents of available nutrients in the 0-40 cm soil layer available for cucumber utilization,and promote the absorption of available nutrients by cucumber plants.It reduced the contents of nitrate nitrogen and available potassium in the soil layer of 40-60 cm,but had no significant effect on the content of available phosphorus in the soil layer of 40-60 cm.Compared with the CK treatment,the cucumber yield,vitamin C content,soluble sugar content and soluble protein content of treatment T 6 increased by 69.27%,29.68%,55.91%and 32.5%,respectively.Compared with treatment T 3(high-concentration inorganic fertilizer),treatment T 6 showed no significant difference in yield,but its nitrate content decreased by 15.97%.Soluble bio-organic fertilizer combined with inorganic fertilizer could be well combined with moistube irrigation,which could not only achieve high yield,but also reduce the risk of environmental pollution caused by fertilization,thus achieving the purpose of saving wat
