A combined seeder is a highly efficient agricultural machine that integrates multiple operations—furrow opening, fertilizing, seeding, soil covering, and pressing—into a single process. Based on the seeding method, it can be classified into pneumatic or mechanical types. It is widely applicable for crops such as wheat, corn, soybeans, millet, sorghum, cotton, rapeseed, alfalfa, and rice.

Core Functions:

1. Furrow opening： Uses coulters or disc openers to create uniform furrows, ensuring consistent seeding depth.

2. Fertilizing： Simultaneously applies base or seed fertilizer deep into the soil, improving nutrient utilization.

3. Precision seeding： Equipped with pneumatic, mechanical, or electric seed meters to control seeding rate and plant spacing accurately.

4. Soil covering & pressing： Soil covering plates or press wheels compact the soil, ensuring good seed-to-soil contact and improving germination rates.

The ANON combined seeder completes furrowing, seeding, fertilizing, covering, and soil compaction all in one pass, dramatically shortening the sowing cycle while ensuring high planting quality. By adjusting the furrow opener height, it guarantees uniform seeding depth, preventing issues like deep seeding that hinders germination or shallow seeding prone to drought damage. The precision metering system accurately controls seed spacing, reducing the need for later thinning. Meanwhile, the fertilizer placement is set 3–5 cm away from the seeds, effectively preventing fertilizer burn and improving germination rates.
