| 针对平原大垄双行覆膜种植模式，研制了一种适合蔬菜钵苗大垄双行栽植的复式联合作业移栽机，对移栽机栽植机构的栽植轨迹和投苗机构的开闭控制参数进行了设计和优化，同时针对传统农机装备地轮深度调控装置难以满足大垄双行膜上栽深精确控制的难题，设计了一种基于可编程控制器的液压栽深仿形装置并整合到移栽机，使得整机可一次性完成旋耕起垄、垄上覆膜、双行独立仿形、膜上Z字形移栽等多道作业工序。分别在45、60株·min-1的栽植频率条件下进行移栽试验，田间试验结果表明：株距合格率、移栽合格率的平均值分别为94.08%、90.45%和91.90%、88.33%，平均栽深合格率为94.15%，较好地满足了蔬菜钵苗大垄双行种植要求。 |

| To solve the problem with lack of matching planting machinery for large ridge double row planting in the plain area, a multiple vegetable block seedling transplanter suitable for large ridge double row was developed. The planting trajectory and switch control mechanism of the vegetable transplanter machine was designed and optimized.At the same time, to resolve the difficulty of depth control device of the ground wheel equipped with traditional agricultural machinery and the problem with precise control of planting depth on the double row film of the large ridge, a hydraulic planting deep imitation device based on the programmable controller was designed and integrated into the transplanting machine. With this new design, the whole machine could complete multiple operation processes such as rotary tillage ridge, ridge coating, double\|line independent profiling, and Z-shaped transplanting on the film at one time. The transplanting test was carried out at the planting frequency of 45 and 60 plants·min-1 respectively, the results of field experiments showed that the average values of the plant spacing and transplanting qualified rate were 94.08%, 90.45% and 91.90%， 88.33%, respectively. The average transplanting depth qualified rate was 94.15%. All parameters and indicators reached the specified values of the industry standard. |
