设施蔬菜水肥一体化技术应用效果研究

为科学评价水肥一体化技术在生产上的实际应用效果，重庆市万州区多种经营技术推广站开展了设施辣椒、黄瓜在常规灌溉及水肥一体化两种管理方式下产量、肥料投入、人工投入、工时投入、经济效益等的对比分析试验。试验结果表明，设施蔬菜生产采用水肥一体化技术，能大幅提高劳动效率、明显降低人工投入成本，增收效果明显，劳动效率提高了7倍；辣椒每667 m2节支801.9元，增收835.3元；黄瓜每667 m2节支515.8元，增收625.7元。

Application Effects of Water and Fertilizer Integration Technology on Greenhouse Vegetables

In order to evaluate the practical application effects of water and fertilizer integration technology, we studied the two different management modes, conventional irrigation and integration of water and fertilizer, on yield, fertilizer input, labor input and economic benefit of pepper and cucumber in greenhouse. The results showed that, integral control of water and fertilizer could sharply improve labor efficiency and it was increased by seven times, at the same time, significantly reduce labor cost and obviously increase benefit income. For greenhouse pepper, the reduced cost and increased income were 801.9 and 835.3 Yuan/667 m2, while for greenhouse cucumber, the reduced cost and increased income were 515.8 and 625.7 Yuan/667 m2, respectively.
