Description

Technical Field

[0001] The invention relates to the technical field of fertilizer application, in particular to a fertilizer application device for soil remediation. Background Art

[0002] The soil remediation process includes two important links: loosening the soil and fertilizing. Spraying liquid fertilizer can be used as a way of fertilizing. Loosening the soil is an important step in soil remediation. By loosening the soil, the soil structure can be improved, the air permeability and water permeability of the soil can be increased, which is conducive to the growth of plant roots and the activity of microorganisms. At the same time, loosening the soil can also promote the decomposition and transformation of harmful substances in the soil, which helps to reduce soil pollution. Liquid fertilizer, as an efficient fertilization method, is also widely used in soil remediation. Liquid fertilizer has the advantages of high nutrient content, easy absorption by plants, and uniform fertilization. In the process of soil remediation, by spraying liquid fertilizer, nutrients in the soil can be quickly replenished, plant growth and development can be promoted, and thus the ecological function of the soil can be improved. In addition to loosening the soil and fertilizing, soil remediation can also be combined with other measures, such as adding soil conditioners, inoculating beneficial microorganisms, etc., to comprehensively improve the soil environment and improve the fertility and ecological function of the soil. Liquid fertilizer is usually mixed with water. Plant roots mainly absorb nutrient ions, and these ions exist in water. In order to be effectively absorbed and utilized by plant roots, fertilizers (whether solid or certain specific forms of liquid) It usually needs to be dissolved in water, and fertilizer needs to be added to the soil during the soil remediation process. However, the fertilizer application devices for soil remediation currently on the market perform poorly in land turning operations. It is difficult to achieve the expected degree of soil looseness after turning the soil, and many large lumps of soil are easily formed during the turning process. These lumps of soil are not fully broken up, resulting in an insufficiently fine soil structure. Some areas may have an excess of fertilizer, while other areas may have a shortage of fertilizer. This uneven fertilization method will seriously affect the fertilization effect, reduce the utilization rate of fertilizers, and may even cause unnecessary damage to the soil.
