The cultivated land in my country's intensive agricultural planting areas has been in a state of high-intensity use for a long time, and the soil has not been reasonably fallow. In order to pursue high yield and efficiency, farmers carry out unreasonable agronomic operations and management measures and blindly use agricultural inputs such as chemical fertilizers and pesticides. As a result, the soil function of cultivated land is rapidly degraded, sustainable production capacity is lost, and continuous cropping obstacles are serious, causing huge losses to agricultural production and directly threatening the quality of agricultural products and environmental security. There is an urgent need for green and efficient ecological control technology solutions.

Aiming at the problem of soil quality decline under high-intensity utilization, this project studied the mechanism of nutrition on healthy plant growth and soil-borne diseases through large-area sampling and multi-angle entry. On this basis, using the principles of ecological chemometrics and according to the nutritional needs of organisms in plants and the soil ecosystems in which they grow, a multifunctional soil health conditioner that activates soil nutrients, adjusts soil pH, inactivates the effectiveness of heavy metals, suppresses soil-borne continuous cropping diseases, and restores degraded soil functions. Through the scientific compatibility of health conditioners and other fertilizers, a nutritional ecological control technical system has been established that integrates crops to "increase production, improve quality, prevent disease, and increase efficiency", improve nutrient utilization, and overcome continuous cropping obstacles.
