摘　　要：针对我国沙生灌木平茬收割效率低、劳动强度大的问题,主要介绍灌木平茬机的结构特点、工作原理,并对其经济效益和社会效益进行分析。灌木平茬机静态投资回收期为130 d,投资收益率为88.3%;背负式割灌机静态投资回收期为13 d,投资收益率为36.4%。与背负式割灌机比较,灌木平茬机投资收益率高,不仅可以带来较大的经济效益,而且可产生一定的社会效益,具有很好的市场前景。In view of low desert shrub harvesting efficiency and labor-intensive problems in our country,structural features and operational principle of shrubs stubble machine,and its economic and social benefits were analyzed. Static payback time of shrubs stubble machine is 130 days,investment rate is 88. 3%. Static payback time of knapsack bush cutter is 13 days,investment rate is 36. 4%. Compared with the knapsack bush cutter,shrubs stubble machine has higher return rate on investment.Shrubs stubble machine could not only bring great economic benefits,but also have some social benefits,and has good market prospects.
