[0002] Soil is the foundation of agricultural production, and its quality is directly related to the yield and quality of crops. Red-yellow soil, as a widely distributed soil type in southern my country, occupies an important position in agricultural production. However, for a long time, due to unreasonable agricultural production activities, such as excessive application of chemical fertilizers, high-intensity planting patterns, and the influence of natural factors such as acid rain, the acidification problem of red-yellow soil farmland has become increasingly serious. Soil acidification will not only reduce the effectiveness of nutrients in the soil, such as changes in the solubility of elements such as phosphorus, potassium, calcium, and magnesium, which are difficult to be absorbed and utilized by crops, but also increase the solubility of harmful heavy metal ions in the soil, which will have a toxic effect on crops and affect the normal growth and development of crops, leading to reduced crop yields or even crop failure. At the same time, the physical properties of acidified soil will also deteriorate, the soil aggregate structure will be destroyed, and the air permeability and water permeability will deteriorate, further affecting the activity and community structure of soil microorganisms and destroying the balance of the soil ecosystem. Therefore, restoration measures need to be taken.

[0003] Most of the existing red-yellow soil farmland acidification repair devices only use alkaline substances such as lime to neutralize the acidic soil, which can only perform simple repairs on the surface of the soil and is difficult to penetrate into the deep soil for effective repair. At the same time, after the red-yellow soil farmland is acidified, the loss of medium elements such as calcium and magnesium is serious, resulting in soil nutrient deficiency and affecting crop growth. The traditional method is not ideal for nutrient supplementation. Therefore, a red-yellow soil farmland acidification repair device is proposed. Summary of the invention
