Description

TECHNICAL FIELD

[0002] With the growth of global population and the limited nature of arable land, improving crop yield and quality has become an important issue in the field of agriculture. As one of the key agricultural technologies to improve crop yield, the efficiency and effectiveness of fertilization directly affect the growth of crops and the sustainable development of agriculture. Traditional fertilization methods often rely on experience, lack of precision, leading to waste of fertilizer and environmental pollution problems increasingly serious. Therefore, shallow fertilization technology emerges as the times require, aims to improve the utilization rate of fertilizer through scientific methods, reduce the impact on the environment, while improving crop yield and quality.

[0003] Shallow fertilization technology, as the name implies, refers to applying fertilizer to the shallow soil near the crop root system so that the crop root system can directly absorb and utilize nutrients. The core of this technology is "precision", that is, applying fertilizer at the right time, in the right place, and in the right amount. Compared with traditional surface application or deep application, shallow fertilization can more effectively deliver fertilizer directly to the crop root system, reduce nutrient loss in the soil, and improve fertilizer utilization efficiency.

[0004] Most existing shallow fertilization devices use a process of first trenching, then fertilizing, and finally covering soil, resulting in complex structural design of the entire device, and also damaging the land surface, which will affect crop growth to some extent. Another type of direct insertion type fertilization device can punch fertilizer into the vicinity of crop root system without damaging the land surface, but it is easy to be damaged by collision when encountering hard objects in the soil. Therefore, improvement is urgently needed. SUMMARY
