Abstract
Description
Technical Field
[0001] This invention belongs to the field of foliar fertilizer technology, and in particular relates to a fourteen-element compound foliar fertilizer. Background Technology
[0002] In current agricultural production, foliar fertilizers are widely used due to their convenient application and quick results. However, existing products generally have shortcomings: most foliar fertilizers have single or unbalanced nutrient elements, either lacking micronutrients or beneficial elements, or easily causing antagonistic reactions between elements, resulting in low crop absorption and utilization rates and failing to cover the comprehensive nutritional needs of different growth stages; at the same time, some products have improper pH control, which can easily burn crop leaves after spraying, and the synergistic ingredients are insufficient, resulting in a short nutrient retention period and difficulty in achieving stable fertilization effects.
[0003] With the increasing demand for improved quality and increased yield in agriculture, traditional foliar fertilizers are no longer suitable for modern planting models: long-term use not only fails to solve the problems of unbalanced crop nutrition and poor quality, but may also exacerbate ecological problems such as soil compaction and nutrient imbalance; while the few compound foliar fertilizers on the market either have complex preparation processes and high production costs, or have defects such as weak formulation targeting and poor compatibility, making it difficult to achieve large-scale promotion. Therefore, the development of a compound foliar fertilizer that is nutritionally comprehensive, scientifically formulated, highly absorbable, safe, and easy to mass-produce has become an urgent need for the industry. Summary of the Invention
[0004] The purpose of this invention is to address the aforementioned technical problems by providing a fourteen-element compound foliar fertilizer.
