AI Technical Summary

Technical Problem

Existing methods of applying base fertilizer have drawbacks such as dispersed nutrient distribution, high risk of loss, low fertilizer utilization, risk of seed-fertilizer contact when sowing seeds and fertilizers together, and low operational efficiency due to the separate steps of fertilization, rotary tillage and compaction.

Method used

The method of applying base fertilizer in strips during crop planting involves breaking up the soil with a rotary tillage unit, applying base fertilizer in strips simultaneously after rotary tillage with a fertilizer dispensing unit, and compacting the soil with a compaction unit to block ammonia volatilization channels, thereby achieving spatial separation of fertilizer and seeds and simplifying the operation process.

Benefits of technology

It improves fertilizer utilization, reduces the risk of seedling burn, enhances operational efficiency, strengthens the physical contact between roots and fertilizer, promotes rapid nutrient absorption by roots, reduces nitrogen loss, and meets the requirements of ecological agriculture development.
