摘要
以黄瓜中农16为试材,研究了不同灌溉方式对其生长、产量、水分生产效率和经济效益的影响。结果表明:与对照相比,膜上沟灌、膜下沟灌和灌水带处理能够促进植株生长、提高产量和水分生产效率。其中膜下沟灌处理的产量、水分生产效率和经济效益最高,产量提高10.1%,处理间差异显著;水分生产效率提高6.5kg/m3,经济效益增加6 291元/hm2。因此,膜下沟灌是春茬黄瓜大棚栽培适宜的灌溉方式。
The effects of different irrigation methods on the growth、yield、water use efficiency and economic benefits of plastic house cucumber Zhongnong No.16（Cucumis sativus L） were analyzed.The results showed that the plant growth、yield and water use efficiency of the furrow irrigation under mulching、furrow irrigation above mulching and plastic irrigation tape were higher than traditional furrow irrigation.The yield、water use efficiency and economic benefits of the furrow irrigation under mulching were the highest.Compared with traditional furrow irrigation,the yield increased by 10.1%,the water use efficiency increased by 6.5kg/m 3,and the economic benefits increased by 6291yuan/hm2 in the furrow irrigation under mulching.Integrated the properties of cucumber yield、water use efficiency and economic benefits in this experiment,the furrow irrigation under mulching is the appropriate irrigation methods of cucumber in plastic greenhouse.
