灌溉方式与氮肥耦合对河西地区洋葱产量、品质及水分利用效率的影响
Effects of Irrigation Method and Nitrogen Fertilizer Coupling on Onion Yield,Quality,and Water Use Efficiency in Hexi Region
摘要
Abstract
To investigate the effects of different irrigation methods and nitrogenfertilizer management on onion yield and resource use efficiency in the Hexi region,a field experiment was conducted using onion cultivar'Xinghongxin'.Two irrigation methods,drip irrigation(D,75％-95％of field capacity,θf)and border irrigation(B,75％-95％θf),and two nitrogen fertilizer application rates,the local farmers'conventional rate(F1,200 kg/hm2)and a 30％nitrogen reduction rate(F2,140 kg/hm2),were set up,resulting in four treatments.The responses of onion growth,soil moisture,yield,water use efficiency(WUE),and quality to the coupling of irrigation method and N fertilizer were systematically analyzed.The results showed that plant height,stem diameter,and dry matter accumulation were high-er under drip irrigation than under border irrigation.Dry matter accumulation at maturity in the DF2 treatment increased by 0.77％-5.40％compared with the other treatments.Total water consumption under border irrigation(740.37 mm and 745.57 mm)was significantly higher than under drip irriga-tion(526.04 mm and 521.84 mm).Soil water storage in the 0-60 cm layer under the DF2 treatment was 6.79％higher than that under DF1.Yield under drip irrigation was significantly superior to that under border irrigation.The DF2 treatment achieved the highest yield and water use efficiency[110800.55 kg/hm2 and 212.76 kg/(hm2·mm),respectively],which increased by 4.96％-63.42％and 5.87％-74.38％,respectively,compared with the other treatments.In addition,onion bulb firmness,soluble sugar content,and soluble protein content were highest under the DF2 treatment,indicating that this treatment was a relatively optimal combination for achieving both high yield and good quali-ty.Overall,drip irrigation combined with a 30％reduction in nitrogen fertilizer application(140 kg/hm2)is the optimal irrigation and nitrogen fertilizer management mode for water-saving and effi-cient onion production in the Hexi region.关键词
