摘要
采用田间试验的方法,探讨2 BQMJ-2型玉米免耕播种机的播种性能。试验和数据分析结果表明,该播种机粒距合格率为100%,播种深度合格率为94%,施肥深度合格率为92%,机组的小时技术生产率为0.54 hm2/h,均优于行业标准。该机具的结构设计合理,作业效率高,完全达到精密播种的质量要求。
In the article, it discussed seeding performance of type 2BQMJ-2 maize no-tillage seeder by taking field test. The test result and data analysis showed that the qualified rate of the machine＇s grain distance is 100%;the qualified rate of seeding depth is 94%;the qualified rate of fertilizing depth is 92%; the technical efficiency per hour is 0.54 hm^2, all of it is higher than industry standard. The machine＇s structure design is logical, its operation efficiency is high, and achieves the quality request for accurate seeding.
