云南晋宁宝峰地区切花月季种植规模对生产成本与产量的影响研究OA

To investigate the effects of cut rose planting scale on production cost and yield,and further optimize the allocation of regional planting resources,this study focused on 58 cut rose growers in Baofeng area of Jinning,Yunnan Province.Questionnaire surveys and field research were conducted to collect data on planting area,production cost and yield.A systematic analysis was conducted using descriptive statistics and Locally Estimated Scatterplot Smoothing(LOESS)method.The results showed that the average planting area for cut rose growers in Baofeng area of Jinning,Yunnan Province was 0.58 hm2,with an average annual production input of 295 233 CNY/hm2.Among production cost,facility cost accounted for the largest proportion,and labor cost exhibited a nonlinear increasing trend with the expansion of cut rose planting scale.The unit area production cost remained relatively low when the cut rose planting scale ranged from 0.33 to 0.47 hm2.The yield of the main cultivar'Peach Snow Mountain'was higher,demonstrating superior cost-yield efficiency.When the cut rose planting scale exceeded 0.47 hm2,increased management difficulty led to higher labor and facility costs,accompanied by a decline in unit area yield.In conclusion,it is recommended that cut rose growers maintain their planting scale within the range of 0.33-0.47 hm2 and focus on improving management efficiency.
