技术的经济效益及技术效果对技术推广具有重要意义。文中基于通辽市农户玉米生产田块尺度的调查数据,从节水灌溉技术的成本收益、技术使用的产量效果两方面对节水灌溉技术进行经济及技术评价,目的是分析不同推广条件的影响,考量技术使用效果。研究结果表明:项目区农户、经营规模30-50亩、高中及以上学历、一兼农户等条件下,推广节水灌溉技术具有更高的比较优势。该区域玉米生长期最佳用水量处于200m~3/亩到300m~3/亩区间。玉米节水灌溉的增产效果在10kg/亩左右,成本收益效果在130元/亩左右。因此,节水灌溉能够显著节约农户生产成本,实现粮食增产,适宜在有条件地区推广使用。
The economic benefits and technical effects of technology are of great significance to technology promotion. Based on the survey data of corn production plots in farmer households in Tongliao City, the economic and technical evaluation of water-saving irrigation technology is carried out from two aspects of the cost-benefit of water-saving irrigation technology and the yield of technology. The purpose is to analyze the influence of different extension conditions, Consider the effect of technology use. The results show that farmers in the project area have a comparative advantage in popularizing water-saving irrigation technology under the conditions of 30-50 mu of operation scale, high school education or above, and one farmer. The optimum water consumption for maize growing in this area is in the range of 200m ~ 3 / mu to 300m ~ 3 / mu. The yield-increasing effect of water-saving irrigation in corn is about 10kg / mu, and the cost-benefit effect is about 130yuan / mu. Therefore, water-saving irrigation can significantly save farmers’ production costs, increase grain output, and be suitable for popularization and use in the conditions of the region.
