Economical benefit of wolfberry field in secondary salinization land of Jingtai Electricalirrigation Area

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 CNY667 m-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 8 500 CNY667 m-2, 3 538.36 CNY667 m-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 2 000～3 000 CNY667 m-2. Furthermore, problems existed in wolfberry production, and some methods and suggestions of reducing cost and increasing efficiency were also putted forward.
