Analysis and optimization of technological path of rapeseed production mechanization from the perspective of cost-benefit
The mechanization of rapeseed production is of great significance to realize the economical and efficient production of rapeseed,promote the increase of farmers'income,and ensure the stable supply of edible oil in China.Taking the rapeseed testing and demonstration area in Xiaonan District of Xiaogan City as a research example,this paper comprehensively sorts out the current status of the technological path of the existing three modes of sowing by drone and rototiller,sowing by combined seed and fertilizer drill and manual direct sowing.Using the grey relation analysis method,this paper excavates and reveals the influencing factors and correlations of rapeseed production mechanization technology on cost-benefit from the aspects of mechanical operation,labor input,material input,technical process,etc.In this paper,the optimization scheme of the technological path dominated by the drone sowing mode with rototiller and the combined seed and fertilizer drill mode is explored and proposed.Finally,in order to meet the inherent needs of light,simple,efficient,cost-saving,labor-saving,and increased production and efficiency in rapeseed production,this paper provides quantitative analysis and theoretical support for promoting the innovative development of regional mechanization technology for rapeseed production.The research indicates that the application of different modes varies considerably in cost-benefit.The choice of different modes is significantly correlated with profitability.There is also a significant correlation between the operation steps,sequence,and frequency within the same mode in terms of profitability.Compared to before optimization,the mode of sowing by drone and rototiller can achieve an average unit cost saving of 9.06％,and increase the average cost-benefit ratio from 26.93％to 39.58％.Although the average unit cost of the mode of sowing by combined seed and fertilizer drill increases by 3.57％,the average cost-benefit ratio can be increased from 2.53％to 16.96％.
