| 中文摘要: |
| 针对我国北方作物机械化收获模式下,机收后滞留在田间大量秸秆留茬处理问题,结合秸秆整株翻埋技术与秸秆快速腐熟还田技术,设计了秸秆留茬翻埋快速腐熟联合作业机。该机由腐熟剂喷施系统及秸秆留茬翻埋系统两部分组成。通过田间试验表明,秸秆留茬翻埋快速腐熟技术可使翻埋的秸秆留茬快速腐解,7个月后秸秆留茬腐熟率为79.8%,较单一秸秆留茬翻埋作业方式腐熟率提高了18.5%;增加了田间土壤微生物数量,提高了土壤有机质含量;相应配套机具在田间作业时,速度应大于1.46 m/s,悬挂深耕犁耕深应控制在22~29 cm之间。 |

| Under the mechanization mode of crop harvest in northem China, a combined machine is designed com-
bining straw stubble burying and the straw returning with fast decomposition technology to handle the problem of large amount of straw stubble remaining in field after the machine harvest. The machine consists of degradation agent spraying system and straw stubble burying system. Field experiments show that the technique can make straw stubble fast decom-posing in short time， and the straw stubble decomposition rate of farmland using this machine reached 79.8% after 7 months, which was 18.5% higher than a single mechanical burying treatment. This technique also increases the soil mi-croorganism quantity and organic matter in soil. When the corresponding ancillary equipment works in the field, the speed should be controlled as more than 1.46 m/s, and the mounted deep plough's tilling depth should be limited be-tween 22~29 cm. |
