No irrigation is required or the irrigation frequency is very low. The sowing period is in the dry season with less rainfall at the junction of spring and summer. In order to ensure that the corn seeds can germinate smoothly, irrigation is required after corn sowing. The field planting of corn is equipped with complete irrigation facilities, but for some scattered small plots in rugged areas such as mountainous areas and hills, manual sowing and fertilization are required, and canned water is used to irrigate the small plots many times, which requires a lot of manpower and time. At present, technicians have developed unmanned walking machines, which can be remotely controlled to walk on the ground, but they are only suitable for walking on flat ground and are not suitable for entering mountainous areas, hills and other areas. How to combine unmanned walking machines with agricultural machinery to achieve automatic sowing and ensure the emergence of seeds in the dry season is a technical problem that technicians in this field need to solve.

[0021] A slotting unit 2, a sowing unit 3, a fertilizing unit 4 and a water retaining agent box 5 are arranged on the unmanned walking frame 1. The unmanned walking frame is moved in a small plot with the help of a remote controller. The unmanned walking frame is visually remotely controlled. During the walking process, slotting, sowing, water retaining agent spreading and fertilizing operations are performed, thereby realizing unmanned driving sowing and fertilizing operations and reducing labor intensity. During the walking process of the unmanned walking frame 1, the slotting unit 2 slots the plot, the sowing unit 3 sows the seeds in the groove, and the water retaining agent box 5 spreads the water retaining agent around the seeds in the groove with the help of the water retaining pipe 6. After the covering plate passes, the soil is covered on the water retaining agent and the seeds to prevent the water retaining agent from being exposed to sunlight and to extend the use time of the water retaining agent. The water retaining agent quickly absorbs and preserves moisture in the soil to prevent moisture from seeping or evaporating. The water retaining agent slowly releases moisture for plant absorption to ensure that there is sufficient moisture around the seeds, effectively reducing the amount of water required for irrigation, further reducing the planting labor intensity of small plots without irrigation facilities in mountainous areas and hills, and helping to improve the emergence rate of crops.

Transmission connection; when the receiving plate 72 rotates and the receiving trough 721 is aligned with the discharge end of the water-retaining pipe 6, the water-retaining agent in the water-retaining agent box 5 falls into the receiving trough 721 along the water-retaining pipe 6; when the water-retaining pipe 6 is located between the two receiving troughs 721, it is blocked by the side wall of the receiving plate 72 and stops dropping; the receiving trough 721 on the receiving plate 72 receives the material, and the receiving plate 72 continues to rotate, and the inner wall of the dropping plate 71 blocks the opening of the receiving trough 721. When the receiving trough 721 rotates to the dropping port 711 of the dropping plate 71, the water-retaining agent in the receiving trough 721 slides along the dropping port 711 to the sowing position.

[0025] Preferably, a guide plate 73 is provided at the bottom of the drop port 711. The guide plate 73 is inclined with a high front and a low rear along the walking direction of the unmanned walking frame 1. The upper end of the guide plate 73 is connected to the bottom of the drop port 711. The water-retaining agent slides along the guide plate 73 to increase the application range of the water-retaining agent, ensuring that the water-retaining agent can cover the area around the seeds and provide moisture for the root growth area of ​​the crop.
