以甘肃省景泰电灌区（二次盐化地）典型枸杞种植村红月村为研究对象，通过对农户的基础调查，调查了枸杞生产中劳动力和生产要素的投入情况，并分析了稳产成熟枸杞田的经济效益和投入产出比，以及不同生长年限枸杞田经济效益的动态变化。年平均生产成本为4 962.44 CNY·667m-2，其中果实采摘及后加工成本占总成本比例最高（54%），其次是田间管理成本（22%），包括施肥、灌溉、修剪等劳动力投入。枸杞生产年收入、纯收入和投入产出比为8 500 CNY·667m-2,3分别为538.36CNY·667m-2和1∶1.72。不同生长年限的枸杞地经济效益不同。枸杞地开始创造经济效益和经济效益最大的阶段分别为3年生和4年～6年生。当枸杞地到8年～9年生时，经济效益为稳定，一般在2 000~3 000CNY·667m-2左右。此外，针对枸杞生产中存在的问题，提出了降本增效的方法和建议。
Taking a typical wolfberry(Lycium barbarum)planting village,Hongyue village,which is located in Jingtai Electric-irrigated Area(secondary salinization land)in Gansu Province as study object,the inputs of labour and production factors in wolfberry production were investigated through a basic survey on farmers.Besides,the economical benefit and input-output ratio of mature wolfberry fields with stable yield,and the dynamic change of economical benefit of wolfberry fields with different growth years were also analyzed.The results indicated that,the average annual production cost was 4 962.44 CNY·667m-2.The cost of fruit picking and post-processing took up the highest ratio on total cost(54%),followed by the cost of field management(22%),including labour input of fertilization,irrigation,trim and so on.The annual revenue,net income and input-output ratio of wolfberry production were 8 500CNY·667m-2,3 538.36CNY·667m-2 and 1∶1.72,respectively.The economical benefits were different among wolfberry fields with different growth years.The stages of beginning to create economical benefits and getting the maximum economical benefit for wolfberry fields were 3-year-age and 4-year-age~ 6-year-age,respectively.When wolfberry fields came to 8-year-age~9-year-age,their economical benefits became to steady,usually around 2 000~3 000CNY·667m-2.Furthermore,problems existed in wolfberry production,and some methods and suggestions of reducing cost and increasing efficiency were also putted forward.
