Description

Technical Field

[0001] This utility model relates to the technical field of deep tillage and fertilization equipment, specifically a protective tillage seedling deep tillage and fertilization device. Background Technology

[0002] Conservation tillage technology can maximize the preservation of the natural structure and ecological functions of the soil during agricultural production, ensuring soil health and sustainable productivity. In the development of modern agriculture, this technology has become a highly regarded agricultural practice. Deep tillage and fertilization during the seedling stage is an important supporting component of integrated conservation tillage technology and is increasingly attracting the attention of agricultural growers. However, traditional deep tillage and fertilization devices often lack efficiency and precision in the fertilization and tillage process, resulting in low fertilizer utilization and impacting crop yield. This presents farmers with challenges in fertilization and tillage, preventing them from fully realizing the soil's productive potential. The main issues are: 1) Traditional fertilization devices often combine fertilization and deep tillage trenching, leading to uneven fertilization depth and poor fertilizer utilization, particularly in the uneven penetration of fertilizer into the soil across rows, resulting in inconsistent corn growth; 2) Traditional deep tillage technology lacks effective compaction methods after deep tillage, resulting in poor soil moisture retention, moisture loss in the topsoil, and fertilizer runoff, thus affecting subsequent crop growth.

[0003] Therefore, there is an urgent need to invent a deep tillage and fertilization device for the seedling stage of conservation tillage, in order to solve the problems of low fertilizer utilization, fertilizer waste, and negative impact on crop growth caused by the lack of effective fertilizer uniformity and compaction and moisture retention effects of traditional deep tillage and fertilization devices.
