黔西北旱地作物玉米生产成本结构调查与分析

The structure analysis of corn production cost of major crops in northwest Guizhou

采用目标层次分析法,对近3年黔西北地区主要旱地作物玉米生产成本构成分析表明,其主要生产成本为人工费用,达193.00元.667m-2,占生产投入总成本的49.8%;其次为肥料投入费用,为82.00元.667m-2,占21.2%。化肥费用投入、人工及畜力费用投入、管理及运输费用投入、农药及农膜费用投入、种子费用投入的权重分别为0.263、0.475、0.055、0.099、0.110。玉米生产投入综合评价指数为0.752 6,说明玉米生产成本投入总体不错,但各项投入比例不均,生产中应对此改进及调整。

Through the analysis of the cost of corn production of northwest Guizhou in the past three years, the main production costs for labor reached 193.00 yuan·667m^-2 ,accounting for 49. 8% of the total cost of production inputs,the following was fertilizer for 82. 00 yuan·667m^-2 accounting for 21.2%. By making use of analytical hierarchy process, the results showed that the weights of chemical fertilizer input costs, labor and animal input costs, management and transportation input costs, pesticides and plastic sheet input costs, investment costs of seed were 0. 263,0. 475,0. 055,0. 099 and 0. 110 respectively. The conclusion was drawn that the comprehensive evaluation index for corn production inputs was 0. 752 6,which meant the overall costs of corn production were quite suitable, but the ratio of inputs were out of line, some adjustments and improvements should be taken during the corn production.
