The invention discloses a material and method for reducing the content of heavy metals and nitrogen and phosphorus in bottom mud, the material is suitable for reducing the content of heavy metals and nitrogen and phosphorus in bottom mud, and the material comprises the following components in parts by mass: 100 parts of calcareous shale, 20-40 parts of steel slag, 6-10 parts of activated carbon powder and 6-10 parts of medium-coarse sand; the sintering material is formed by sintering a mixed material, and the mixed material comprises the following components in parts by mass: 100 parts of calcareous shale, 20-40 parts of steel slag, 6-10 parts of activated carbon powder and 6-10 parts of medium-coarse sand; and 2-4 parts of an adhesive. The material for reducing the contents of heavy metals and nitrogen and phosphorus in the bottom mud not only blocks the pollution of sludge to water quality, but also effectively reduces the contents of heavy metals and nitrogen and phosphorus nutrients in the bottom mud in situ, and can reduce the thickness of the bottom mud, improve the characteristics of the bottom mud and really realize harmless treatment of the bottom mud.

This invention discloses a land maintenance method and apparatus suitable for the cultivation of Suaeda salsa in wetland areas, relating to the field of ecological restoration and land improvement technology. Ecological restoration is achieved through an ecological restoration fertilizer comprising: 30-60 parts Suaeda salsa powder, 30-60 parts segmented Suaeda salsa grass, and 1-5 parts fermentation agent. The preparation method of the ecological restoration fertilizer includes the following steps: harvesting Suaeda salsa mother grass on land; dividing the obtained Suaeda salsa mother grass into two parts; pulverizing the first part and passing it through an 80-100 mesh sieve to obtain Suaeda salsa powder. This invention uses harvested Suaeda salsa mother grass as raw material to prepare an ecological restoration fertilizer. The resulting fertilizer has sufficient nutrients and a high microbial content, making it suitable for soil improvement in coastal tidal flats. It can enhance soil fertility, improve soil permeability, prevent soil compaction, and promote strong root development when planting Suaeda salsa.

The invention relates to the technical field of fermentation product stirring, and discloses a melon vine fermentation product stirring device which comprises a gas treatment component, the gas treatment component further comprises a shell, the surface of the shell is fixedly connected with a sealed discharge port, and the inner wall of the shell is fixedly connected with a fixing plate. According to the device, gas pressure generated in the fermentation process of fermented materials is utilized, the device is provided with the rubber round block, the fixing block and the spring, when the fermented materials are stirred in the device, the fermented materials fully react to generate unreacted gas such as carbon dioxide and nitrogen, and the gas can not react with the gas. When more and more gases incapable of reacting exist in the device, a fixed circular plate is extruded, the fixed circular plate can move after being extruded to push a fixed supporting plate to move, and under the action of a spring, one end, far away from the spring, of a movable long plate can move upwards.
