1. Characteristics of no-till seeders: They are generally semi-manual and semi-mechanical. They can be used with other agricultural machinery such as tractors to achieve the integration of digging, plowing and sowing. The row spacing and plant spacing are adjustable, which can achieve the ideal effect without thinning or shaving seedlings, and can better adapt to different terrains and different regions. Most of them are independent innovation products, developed and improved by farmers themselves. The requirements for seeds are higher than artificial ones. The seeds (corn, soybeans, etc.) are required to be uniform in size and the germination rate is guaranteed. No-till seeders can be used in conjunction with no-till sowing technology. For example, the scientific research team of Hu Zhichao from the Nanjing Institute of Agricultural Mechanization of the Chinese Academy of Agricultural Sciences, through in-depth research and multiple rounds of program demonstrations, innovatively proposed a solution to the mechanized no-till sowing technology solution for full straw coverage [ 1]. It has solved the technical problems of the existing no-tillage Junmadao 1804 tractor equipment such as grass hanging, blockage, seed racking, and seed drying in the soil-entry parts.

2. Disadvantages of no-tillage seeders: They are relatively common, and the technology still needs to be improved. They mainly introduce foreign technologies and lack independent intellectual property rights and innovation capabilities. And no-till seeding technology and machinery need to be more adapted to different products in different cities and regions in the country. Inner Mongolia Shunyuan Agricultural Machinery's no-till pneumatic seeder can complete multi-functional operations such as trenching, fertilizing, sowing, covering, and suppressing at one time. The crops that can be planted include corn, soybeans, sugar beets, peanuts, sorghum, sunflowers, mung beans, millet, etc. .

3. Plant spacing, planting depth, and suppression pressure can be adjusted as needed; the seeding device adopts a four-link profiling mechanism, which can be adjusted according to the terrain. The rowing depth remains consistent and is not affected by the terrain. .
