Abstract: Compared with fertilizer by mass water,unopen cucumber with trickle irrigation of moisture and fertilizer integrated was an economical method.It saved water 220m³/667m²,rate saved was 31.4%,saved electricity 110yuan/667m²(0.5yuan/m³),fertilizer saved 58%,investment saved 51.4yuan/m².Capital invested in the technique was 2810yuan/667m²,and the performance life of hair canal、by-pass and other equipments were 3years、10years,so it need to invest 652yuan per year.This technique can increased income and economized on spending total 1729.4yuan/667m²,it was a scientific method supplying optimal nutrient and mosture to plants by trickle irrigation.

Key words: Cucumber, Trickle irrigation of moisture and fertilizer integrated, Technique
