Therefore, during the sowing operation in the farmland, the complete sowing operations of preparing the land before planting, fertilizing, laying the drip irrigation tape, laying the film, sowing, covering the film with soil and pressing can be completed in a single time. Compared with the traditional sowing operation in which multiple machines are repeatedly put into the land, the sowing machine can protect the soil, improve the operation efficiency and reduce the operation cost.

[0018] Furthermore, the soil-lifting mechanism can drop soil into the sowing pit of the sowing mechanism, thereby ensuring the effect of burying the seeds with the soil.

[0019] Furthermore, the sowing mechanism is composed of a plurality of air-suction seeders, the components of which are common and easy to obtain. It is a widely used seeder for existing single-grain stable sowing and has strong sowing adaptability.

[0020] Furthermore, multiple air-suction seeders are used, and intercropping can be completed by placing the corresponding corn and soybean seeds into the corresponding air-suction seeders. Moreover, the use of air-suction seeders can achieve more uniform and stable sowing.

[0021] Furthermore, the air-suction seeder adopts an air-suction seed meter to realize the sowing operation of a single seed. It has a simple structure and can sow stably.

[0023] Furthermore, the fertilizing mechanism uses a fertilizer guide pipe to connect the fertilizer box with the fertilizer furrow opener to complete the fertilizing action, which can effectively control the amount and position of fertilizer, and ensure that the fertilizer is accurately located in the fertilizer furrow.

[0024] Furthermore, the two air-suction seeders share one electric blower, which can greatly reduce energy consumption compared to each seeder being equipped with an independent blower. Since the two seeders share one electric blower, they can be easily adjusted synchronously, reducing the cost investment of the equipment and simplifying the maintenance of the equipment.

[0025] Furthermore, through the coordination of various components and the combination of springs, the pressing wheel always maintains a pressing effect on the soil, compacting the soil through its own weight and the forward power of the all-in-one machine; when the pressing wheel encounters soil or obstacles of different hardness, the spring can automatically adjust the compression amount according to the force conditions, thereby changing the pressure of the pressing wheel on the soil.
