| 摘 要： | 为解决虾稻共作模式下稻田土壤淤泥层较深、易陷机等问题,开展了履带自走式旋耕机与轮式拖拉机配套旋耕机对比试验。结果表明,履带自走式旋耕机作业效率略低于轮式拖拉机,但碎土率提高4.9个百分点、耕深增加2.3 cm、机体下陷深度减少11.1 cm,作业后平整度优于轮式拖拉机,且履带自走式拖拉机未出现田间陷机现象,减少了耕整机具对田间土壤的碾压,保护了耕作层的土壤结构。

| Abstract: | In order to solve the problems of deep soil silt layer and easy trapping machine in the paddy field under the shrimp-rice co-cultivation mode, a comparative test was carried out between the self-propelled rotary tiller and the wheeled tractor. The results showed that the operating efficiency of the crawler self-propelled rotary tiller is slightly lower than that of the wheeled tractor, but the soil crushing rate is increased by 4.9 percentage points, the ploughing depth is increased by 2.3 cm, and the body sinking depth is reduced by 11.1 cm. The flatness after operation is better than that of the wheeled tractor. In addition, there is no field trapping phenomenon in the crawler self-propelled tractor, which reduces the crushing of the field soil by the tillage machine and protects the soil structure of the tillage layer. |
