- 摘要:
- 在北方垄作秸秆根茬残留量为0。994 kg?m-2的人工收获后玉米原茬地上,测试分析2BMFJ-BL5型大豆原茬地免耕覆秸精量播种机田间作业性能。在作业速度5 km?h-1条件下,按照中华人民共和国机械行业标准NY/T1768-2009《免耕播种机质量评价技术规范》实施了本次试验。结果表明:播种均匀性达到了国家标准优等品标准,播种深度合格率达到了国家一等品的标准。各行排肥量一致性变异系数达到了国家一等品的标准,总排肥量稳定性变异系数达到了国家优等品的标准。秸秆清秸率达97%以上,植被覆盖率达97%以上,田间出苗率达94%以上。试验结果为2BMFJ-BL5型大豆原茬地免耕覆秸精量播种机的产业化和推广应用提供了理论依据。
- Abstract:
- In the corn stubble ridge of North China, the amount of residue of straw stubble was 0.994 kg?m-2?after manual work, testing and analysis the work performance in the field of 2BMFJ-BL5 no-tillage soybean precision seeder in stubble field.In the condition of operating speed 5 km?h-2, this experiment was carried out according to the People’s Republic of China Machinery Industry Standard NY/T1768-2009 ‘Technical specifications of quality evaluation for no-tillage drilling machinery’. The test results showed that sowing uniformity reached the superior standard of national standard and the passing rate of planting depth up to the national standard which first-class goods. The coefficient of variation about each row fertilizer consistency up to the national standard which first-class goods, the stability coefficient of variation of the amount of fertilizer reached the excellent products of national standard. Straw clearance rate was more than 97%, vegetation coverage rate was more than 97%, the emergence rate was greater than 94%. This test results could provide a theoretical foundation for the industrialization, popularization and application of 2BMFJ-XH5 no-tillage soybean precision seeder in stubble field.
