保护地黄瓜水、肥一体化高效栽培技术

High-effective Culture Technique of Unopen Cucumber with Trickle Irrigation of Moisture and Fertilizer Integrated

保护地黄瓜水、肥一体化技术与大水冲施进行对比试验,结果表明:节水220m3/667m2,节水率达31.4%。节水电费110元/667m2(每m3按0.5元计算),节省化肥58%,节省投入51.4元/667m2;水、肥一体化技术一次性投资约2810元/667m2,毛管使用寿命一般可达3年以上,支管和其他设备寿命以10年计算,每年投入652元。增收节支合计可达1729.4元/667m2,它是利用滴灌设施将作物需要的养分、水分最低限度地供给作物,满足作物生长需要。

Compared with fertilizer by mass water,unopen cucumber with trickle irrigation of moisture and fertilizer integrated was an economical method. It saved water 220m^3/667m^2,rate saved was 31.4%, saved electricity 110yuan/667 m^2（0.5yuan/m^3）, fertilizer saved 58%, investment saved 51.4yuan/m^2. Capital invested in the technique was 2810yuan/667m^2, 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 1729.4yual/667m^2, it was a scientific method supplying optimal nutrient and moisture to plants by trickle irrigation.
