摘要
为了适应朝阳市保护性耕作的发展需要,针对朝阳地区的玉米机械化耕种模式进行了效益分析。结果表明,保护性耕作模式平均增产64.5 kg/667 m^(2),单位面积节约成本34.71元/667 m^(2),推广应用保护性耕作机械化技术对扭转半干旱地区旱灾频繁、水土流失严重、生态环境恶化等不利局面具有重要意义。
In order to meet the development needs of conservation tillage in Chaoyang city,the benefits of mechanized maize tillage in Chaoyang area were analyzed.The results showed that the average yield of conservation tillage was 64.50 kg/667 m^(2),and the cost per unit area was 34.71 yuan/667 m^(2).The popularization and application of conservation tillage mechanization technology is of great significance to reverse the adverse situation of frequent drought,serious soil erosion and ecological environment deterioration in semi-arid areas.
