The application discloses a low-carbon solidified soil matrix and application. The matrix is made of dredged soil, biochar, slag and gypsum mixed in a specific ratio, and the preferred ratio (T1) is that the mass ratio of the dredged soil, the biochar, the slag and the gypsum is 60:15:10:15. By comparing the mechanical properties and the plant growth effects of different ratios (CK, T1, T2 and T3), it is found that the unconfined compressive strength of the T3 ratio (with the highest content of slag) is the highest (up to more than 3000kPa) after 60 days; however, the T1 ratio (with the highest content of biochar) exhibits the best ecological effect, including significantly promoting the growth of ryegrass, increasing the biomass, optimizing the carbon-nitrogen ratio of soil and enhancing the soil microbial activity, while maintaining sufficient engineering strength (about 1000kPa after 60 days) and excellent dry-wet cycle performance. The application realizes the balance between the mechanical and ecological restoration functions through the collaborative utilization of multi-source solid wastes, and provides an economic, environment-friendly and efficient solution for erosion areas.

The present application relates to grassland management technical field, particularly to a kind of desert steppe management method.The present application is by fertilization treatment, plant species group, sand barrier setting and four heavy technology coordination of comprehensive management, significantly improve vegetation coverage and species diversity;Sand barrier and management measures synergistic effect, effectively fixed sandy soil, keep soil moisture;The use of microbial fertilizer enhances soil microbial activity, promotes nutrient cycling.The present application provides a management method, which can select the optimal combination mode according to different site conditions.In practical application, the specific conditions of desert steppe can be selected according to the fertilization mode, plant combination, sand barrier type and management measures, and the corresponding management system is constructed.

This invention relates to the field of water pollution control technology and discloses a reservoir cyanobacteria treatment device for water pollution control. The device includes a floating platform, a temperature sensor, a pH sensor, an aeration pipe, a cleaning component, an air storage tank, and a triggering mechanism. The temperature and pH sensors are fixed to the floating platform and inserted downwards into the water. The aeration pipe is located below the floating platform, and its aeration intensity is dynamically adjusted according to the detected temperature and pH values. The air storage tank is connected to the aeration pipe via an inflation pipe, and its air storage rate is positively correlated with the aeration intensity. The triggering mechanism activates the cleaning component to clean the sensor surface when the air pressure inside the air storage tank reaches a set threshold. This invention, when water quality deteriorates and requires increased treatment efforts, simultaneously enhances the cleaning frequency of the sensors, ensuring the accuracy of monitoring data and improving the effectiveness of water pollution control and the reliability of system operation.
