Abstract：In order to ensure quality and production of greenhouse vegetables and improve the efficiency of water saving irrigation at the same time,cucumber "Zhongnong No.26" was used as test material to study the effects of different trace irrigation,fertilization process integration modes on cucumber growth,yield and quality.The results showed that the fertilizer rate and fertilization frequency were able to affect the cucumber growth,yield and quality separately,the effect of the increase of fertilizer on the quantity of cucumber dry matter accumulation was not significant,and low fertilizer rate treatment was beneficial to increase the amount of cucumber dry matter accumulation.When the fertilizer rate increased from 60％ of the local fertilizer levels to 80％,the processing production increased by 20.65％ on average,and the low frequency treatments had the highest yield.In addition,low fertilizer treatment was advantageous to the reduced form VC and soluble sugar accumulation in fruit.The low frequency fertilization can handle both yield and water use efficiency and quality,and is more suitable to fertilization mode.Besides,the fertilization way,which is more simple and easier to operate,can be applied widely.
