The garden water-saving road comprises a roadbed and drainage pipelines arranged on the two sides of the roadbed, sewage intercepting structures are arranged on the drainage pipelines, a collecting channel is arranged on one side in each drainage pipeline, and each sewage intercepting structure comprises a sewage intercepting net between the corresponding drainage pipeline and the corresponding collecting pipeline and a drainage cover plate arranged on the corresponding drainage pipeline. Filtering holes are formed in the sewage intercepting net at intervals, and the aperture of the filtering holes, close to the drainage pipeline, below the sewage intercepting net is smaller than that of the filtering holes above the sewage intercepting net; water taking holes are formed in the collecting channel at intervals. Water entering the collecting channel is filtered in a classified mode through the sewage intercepting net with different hole diameters, silt and the like deposited at the bottom of the drainage channel are further intercepted through the filtering holes with the small hole diameters, the impurity removal effect on the water flowing into the drainage channel is improved, the water quality is improved so that the water can be recycled for garden irrigation and the like, and water saving is facilitated; when the abutting plate rotates to be staggered with the drainage cover plate, the drainage cover plate can be conveniently opened to clean silt and the like deposited in the drainage channel, and operation is more convenient.

The utility model belongs to the technical field of food processing, and discloses a processing system for pickling bamboo shoots, which comprises a sulfur removal tank, a pre-cooking pot and a cooling tank which are sequentially arranged along a production line, a warm water outlet is formed in the tail end of the sulfur removal tank, so that water entering the sulfur removal tank flows; the cooling tank is provided with a cold water inlet, and a circulating mechanism is arranged between the desulphurizing tank and the cooling tank. According to the utility model, the sulfur removal efficiency can be effectively improved on the basis of saving water and time.

The preparation method comprises the following steps: uniformly mixing a formaldehyde aqueous solution with urea, carrying out a heating reaction, adding an oxidized sodium carboxymethyl cellulose aqueous solution into the obtained reaction solution, uniformly mixing, and adding potassium dihydrogen phosphate to obtain a solution A; uniformly mixing a gelatin aqueous solution and a sulfydryl polyvinyl alcohol aqueous solution to obtain a solution B; and mixing the solution A with the solution B to obtain the biodegradable polymer sustained and controlled release liquid fertilizer.

The invention relates to a drying device and a carbon molecular sieve preparation device. The carbon molecular sieve preparation device comprises a carbonization furnace, an incinerator, a waste heat furnace and the drying device. The drying device is used for drying materials, the carbonization furnace is used for carbonizing the materials and conveying combustible gas generated in the carbonization process to the incinerator, and the incinerator is used for incinerating the combustible gas and conveying the incinerated gas into the drying furnace of the drying device to dry the materials. The drying device comprises a drying furnace, an air inlet assembly and an exhaust assembly. The drying furnace comprises a furnace pipe and a hearth, a containing cavity is defined in the hearth, and the furnace pipe is arranged in the containing cavity and used for drying materials; one end of the gas inlet assembly communicates with the containing cavity, and the other end of the gas inlet assembly communicates with the incinerator so as to introduce gas in the incinerator into the containing cavity; one end of the exhaust assembly communicates with the containing cavity, and the other end of the exhaust assembly is used for communicating with the waste heat furnace so that gas in the containing cavity can be conveyed to the waste heat furnace.

This invention discloses a synergistic method for cold-season grazing and warm-season fertilization in alpine meadows, belonging to the field of alpine grassland ecological restoration and sustainable agricultural management technology. The method includes the following steps: using UAV remote sensing to acquire spatial distribution information of litter in the cold-season grassland, and dividing the grassland into patches with different litter loads based on this information, implementing differentiated grazing by region; using a soil sensor network buried in the grassland to monitor soil temperature and moisture content, dynamically defining the start and end times of cold-season grazing and the operational window for warm-season fertilization; during the warm season, spraying the grassland with liquid nitrogen and phosphorus fertilizer containing synergists according to the warm-season fertilization operational window. This invention deeply couples the physical disturbance of cold-season grazing with the chemical regulation of liquid nutrients in the warm season, solving problems such as slow litter decomposition, low fertilizer utilization, delayed greening, and decreased soil fertility in alpine meadows, achieving a synergistic improvement in grassland production and ecological functions.

The application discloses a kind of flush valve group and closestool, flush valve group includes first switching component, water pump, pump spray pipe line, water inlet pipe, first valve group and washing pipe, closestool includes flush valve group.In the application, the water outlet opening of flush valve group in second working mode and the flow of water flow in pump spray pipe line are larger, and first working mode and second working mode are carried out in turn, first in first working mode Water seal water supply and washing flush can be carried out to closestool skirt dirt, and soak closestool bottom spray port place dirt, make subsequent cleaning more thorough, and the water flow in pump spray pipe line is smaller in this process, it is beneficial to water saving;When being jetted in second working mode to closestool, since the opening of water outlet is larger, it can produce transient large flow beneficial to siphon, the jetting flush of closestool is more thorough, and the flushing effect of closestool can be improved.
