Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, in particular to a no-tillage sowing and fertilizing machine for wheat stubble multiple cropping with sorghum and millet. Background Art

[0002] No-till seeding and fertilization equipment is a core component of conservation tillage technology in modern agriculture. Its design concept is to complete seeding, fertilizing, and covering operations simultaneously without plowing the soil, thereby reducing soil disturbance and improving fertilization and seeding efficiency. With the development of intelligent agricultural power machinery, no-till seeding and fertilization equipment has further improved operational efficiency and ecological benefits by integrating technologies such as the Internet of Things, artificial intelligence, and precise navigation. Furthermore, it achieves efficient resource utilization through data and automation.

[0003] In the prior art, in the process of using no-till sowing and fertilization equipment for wheat stubble replanting operations, in order to ensure sufficient contact between seeds and soil and to ensure the seed emergence rate, it is generally necessary to crush the crop straw residues in the cultivated soil before sowing or fertilizing. For example, in the prior art, a Chinese invention patent with authorization announcement number CN116210385B proposes a no-till side deep fertilization precision direct seeding machine, which uses a stubble destroying device to crush the straw residues of the previous crop in the cultivated land before sowing.

[0004] However, the straw fragments produced after being crushed by the stubble-killing device of the above-mentioned no-tillage side deep fertilization precision direct seeding machine are still mixed in the surface soil of the cultivated land. After sowing, when the seeds come into contact with the larger volume of straw fragments in the soil, it will still cause difficulty in anchoring the seed roots, thereby adversely affecting the seed germination rate.
