摘要
通过设计滴灌施肥与传统水肥两种不同模式,对水肥利用效果进行比较研究。试验结果表明,设施菜田采用灌溉施肥技术具有良好的节水节肥效果,能够提高蔬菜产量和收益。与对照相比,灌溉施肥技术节省水肥药分别为52%,46.4%,42%,提高产量20%,纯收益提高35.5%。该研究为今后水肥一体化技术在设施菜田的推广应用提供一定的科学参考依据。
By designing the two comparative treatments, the effect of different water and fertilization treatments on water and fertilizer use were studied. The results showed that the fertigation technology had good water-saving effect of water and fertilizer, to improve yield and income in greenhouse vegetable. Compared with the control, integrated technology of water and fertilizer saved fertilizer rate of 52%, water-saving rate of 46.4%, pesticides-saving rate of 42%, and increased production and net benefits by 20%, 35.5%, respectively. This research provided some scientific references for spreading fertigation technology in greenhouse.
