摘要
水肥一体化滴灌技术是提高设施蔬菜水分利用率的有效途径之一。本文设置了三个不同施肥量处理,对滴灌施肥与畦灌冲肥做了比较。试验结果表明:设施黄瓜采用水肥一体化滴灌技术具有较好的节水节肥效果,能够提高黄瓜产量,改善黄瓜品质,同时提高水分利用率。水肥一体化滴灌技术虽然需要投入一定的成本,但依然能够获得一定的经济效益。本试验可为今后水肥一体化滴灌技术在设施黄瓜上的推广应用提供一定的理论基础和技术支持。
Technology of drip irrigation of integral control of water and fertilization is one of the most important measures to improve water use efficiency under protected cultivation. This paper applied three different fertilization treatments and compared the effect of fertilization drip irrigation with that of border irrigation. The results showed that the integral of control of water and fertilization could save water and fertilizer, increase yield, improve quantity, and enhance water use efficiency. Although external cost should be paid in integral control of water and fertilization, but some economic benefit can be obtained. This experiment results may provide the theoretical basis and technical support for cucumber under protected cultivation.
