为了验证水肥一体化技术在甘肃省河西灌区啤酒花种植中的节水增产效果,开展了连续两年的田间小区试验。试验共设3个处理,分别为常规施用水肥(对照组)、滴灌施用水肥(试验组)、在试验组的基础上减施化肥20%(减肥组),考察了不同处理对啤酒花产量、品质、经济效益的影响。结果表明:试验组和减肥组连续两年的啤酒花产量较对照组分别增产8.32%和3.60%、13.62%和6.61%;试验组的啤酒花中甲酸含量比对照组有所提升;试验组和减肥组连续两年的经济效益比对照组增加1.98~5.38万元/hm2;在滴灌模式下,土壤深度15、25 cm处的地温基本高于对照组的,有利于啤酒花的生长。水肥一体化技术在啤酒花种植中的应用,既提高了作物产量,又大幅节省了灌溉用水。
In order to verify the effects of water and fertilizer integration technology on water saving and yield increasing in planting hops in Hexi irrigation area of Gansu province, a field plot experiment is carried out for two consecutive years. Three treatments are set up in the experiment, including conventional application of water and fertilizer (control group), drip irrigation application of water and fertilizer (experimental group), and 20% reduction of chemical fertilizer on the basis of the experimental group (fertilizer reduction group). The effects of different treatments on the yield, quality and economic benefits of hops are investigated. The results show that the hops yield of the experimental group and the fertilizer reduction group increases by 8.32% and 3.60%, 13.62% and 6.61% for two consecutive years, respectively, compared with the control group. The formic acid content of hops in the experimental group is higher than that in the control group. The economic benefits of the experimental group and the fertilizer reduction group for two consecutive years increase by 19 800~53 800 yuan/hm2 compared with the control group. Under drip irrigation mode, the soil temperature at the depth of 15 and 25 cm in the main is higher than that of the control group, which is conducive to the growth of hops. The application of water and fertilizer integration technology in planting hops has not only increased the crop yield, but also has greatly saved irrigation water.
