By constructing a multi-layer and multifunctional oasis protection barrier system, desertification control and oasis protection system construction are achieved, regional economic development and biodiversity recovery are promoted, and the win-win situation of ecological benefits and economic benefits is achieved.

The utility model relates to the technical field of flood control, and discloses a water-saving irrigation flood control device which comprises a dam, a supporting frame is fixed to the top of the dam, a limiting frame is installed on the inner side wall of the dam, and a gate used for flood control or irrigation is seamlessly inserted into the inner wall of the limiting frame. A water level sensor and a mesh box are installed on one side of the dam, a water pump used for water saving and drainage is installed in the mesh box, and the water outlet end of the water pump communicates with a drainage pipe located on the other side of the gate. A motor output shaft drives a second gear to rotate, a gate drives a sliding rod to move upwards, water passes through the gate from one side of a collecting box, the farmland on one side of the gate is irrigated through the water, and when flood comes, the gate shields one side of a dam at the moment, and the flood is prevented from entering an irrigation canal on the other side of the gate; the influence of flood on the growth of crops is avoided, the gate is controlled by the motor to rise, water flows from the collecting box to the farmland for irrigation, and the gate can be quickly closed when the flood comes.

The utility model relates to an ecological ditch for purifying farmland recession. The method is suitable for the technical field of ecological restoration. The technical problem to be solved by the application is to provide an ecological ditch for purifying farmland recession. According to the technical scheme adopted by the invention, the ecological ditch for purifying the farmland recession water is characterized by comprising an ecological ditch body, and a water inlet for introducing the farmland recession water is formed in the upstream of the ecological ditch body; the ecological permeable dam is arranged on the upstream of the ecological ditch body and can intercept suspended solids and particulate matters flowing through the farmland recession and provide adhesion and growth matrixes for microorganisms in the ecological ditch body; the water level adjusting structure is arranged in the ecological ditch body and can adjust the water level in the ecological ditch body, so that the ecological environment in the ecological ditch body is kept stable.

The invention relates to an antibiotic-free feed additive for breeding crucian carps and a preparation method of the antibiotic-free feed additive, and belongs to the technical field of feed additives. According to the feed additive, seaweeds and Chinese herbal medicines are used as raw materials and are subjected to staged fermentation with compound probiotics, a phagostimulant is added, and freeze drying is performed to prepare the antibiotic-free crucian breeding feed additive, so that the prevalence rate of crucian can be reduced, the survival rate can be increased, and the growth of crucian can be accelerated; the problem of drug resistance caused by antibiotic abuse in crucian breeding in the prior art can be solved, and unification of high antibacterial activity, biological safety and environmental friendliness in crucian breeding is achieved.

The water conservancy slope protection reinforcing device comprises a slope body, a fixing assembly is arranged on the slope body, the fixing assembly comprises a supporting block, a winch, a mooring rope, a connecting block, a rotating block, a joining block and a positioning block, the supporting block is fixedly connected to the top of the slope body, the inner wall of the supporting block is rotationally connected with the winch, and the mooring rope is arranged on the winch. A winch is arranged on the supporting block, a cable is fixedly connected to the outer wall of the winch, a connecting block is arranged above the supporting block, a rotating block is rotatably connected to the inner wall of the connecting block, a connecting block is connected to the rotating block, and a positioning block is fixedly connected to the top of the connecting block. And thus, a rotating block on a connecting block is driven to rotate, a connecting block and a positioning block are driven to move, and the technical problem that in the background technology, most slope protection reinforcing devices in the current market are poor in effect when facing water flow impact is solved.

The invention discloses an ecological soil retaining structure and a slope ecological environment construction method.The second gear is provided with a belt rod, the belt rod is connected with a linkage rod, the linkage rod is provided with a connector, the output end of the connector is provided with an arc-shaped head, and a baffle is arranged in the rotating direction of the arc-shaped head; the device comprises a material groove, a baffle is arranged in the material groove, the baffle is slidably connected to an output port of the material groove, one side of the material groove is rotationally connected with a rotary drum, non-woven fabric is arranged on the rotary drum, and the output end of the non-woven fabric is located at the output end of a laying vehicle. After the servo motor is started, the laying vehicle is pushed to move along the construction position, the non-woven fabric can be laid on the ground, and the seeds are discharged in the laying process, fall onto the non-woven fabric and finally move on the ground, so that simultaneous construction of the non-woven fabric and the seeds is realized, and the efficiency is improved.

This utility model discloses a sterilization device for shrimp ditches in rice-shrimp farming, relating to the field of shrimp ditch sterilization technology. It includes a sterilization powder storage box, a feeding hopper on one side of the top surface of the storage box, a control panel on the other side of the top surface, two symmetrically arranged push handles on the upper part of one side of the storage box, a support rod fixedly connected to the lower part of one side of the storage box, a moving component on one side of the bottom surface of the storage box, and a discharge hopper connected to the lower part of the other side of the storage box.
