The application discloses a pilose antler mushroom strain fermentation tank, which comprises a fermentation tank body, a cover body fixedly connected to the upper position of the fermentation tank body, and a stirring assembly fixedly arranged at the cover body and used for stirring the strain; and a gas supplement assembly is arranged, so as to solve the problem that the ordinary fermentation tank is prone to reducing the fermentation efficiency due to the deposition at the bottom of the fermentation tank and the lack of oxygen at the deposited bottom during the fermentation of the pilose antler mushroom strain. The stirring assembly and the gas supplement assembly are cooperatively used to automatically introduce oxygen when the liquid strain is stirred, and the oxygen is filtered when the oxygen is introduced, so that the bacteria in the air are avoided from entering, and the pilose antler mushroom fermentation culture is particularly suitable.

This utility model discloses a rice cultivation pot based on capillary self-watering and root oxygenation, belonging to the technical field of agricultural crop cultivation equipment. It includes a pot body with an open top; a partition is installed in the inner cavity of the pot body; the partition is placed horizontally and divides the pot body into an upper cultivation area for placing seedling substrate and cultivating seedlings, and a lower water storage area for storing liquid fertilizer and water; several capillary fiber ropes are installed on the partition; one end of each capillary fiber rope is placed at the bottom of the water storage area, and the other end extends through the partition into the seedling substrate in the cultivation area; the capillary fiber ropes can transport water from the water storage area to the seedling substrate in the cultivation area through capillary action; several ventilation holes are opened on the side wall of the pot body above the highest water storage height of the water storage area; effectively solving the problems of uneven water management, root hypoxia, and low fertilizer utilization rate existing in traditional rice seedling cultivation devices.

The present invention discloses an intelligent fermentation system, which belongs to the technical field of sewage fermentation, including a stirring rod which is a hollow tube, the stirring rod is rotatably arranged in a pool body, and stirring blades are arranged on the stirring rod; a ventilation cavity is arranged in the stirring blade, an air outlet is opened on the stirring blade, an air inlet pipe connects an external air supply device and the stirring rod, and a pressure control valve is fixedly installed on the other end of the stirring rod, and the pressure control valve is used to automatically open when the pressure in the stirring rod reaches a preset value; a heater is arranged on the air inlet pipe, and the heater is used to heat the gas passing through the air inlet pipe. In this application, by arranging a pressure control valve on the stirring rod, after the air outlet is blocked by impurities, since the external air supply device continues to ventilate the stirring rod through the air inlet pipe, the air pressure in the stirring rod will increase at this time, and the pressure control valve will be opened, so that the amount of oxygen entering the pool body can be guaranteed, avoiding affecting the sewage fermentation.

The high-pressure air supply rubber tube and the high-pressure air supply steel tube are connected through a pipe connector. The electric control system includes an in-vehicle electric control device, and the in-vehicle electric control device includes a central processing unit 1, a magnetic suction device control module, and a power module. The central processing unit 1 is respectively connected to the magnetic suction device control module and the power module.

This invention belongs to the field of acidifier technology, specifically relating to an acidifier that can improve the health of breeding ducks and the hatchability of hatching eggs, its preparation method, and its application. The acidifier includes acidifier A and acidifier B. Acidifier A is prepared by mixing and adjusting the volume of calcium formate, acetic acid, lactic acid, monk fruit extract, and an immune enhancer; acidifier B is prepared by mixing and adjusting the volume of calcium propionate, citric acid, malic acid, stevia extract, and an antioxidant. This invention enhances the immunity and antioxidant capacity of breeding ducks and improves eggshell quality by intermittently and alternately adding the two acidifiers to their drinking water during the egg-laying period. Furthermore, by spraying a proportionally diluted mixture of the two acidifiers during the later stages of hatching, it improves embryonic calcium absorption and duckling shell-pecking rate, reduces embryonic mortality, and significantly increases the hatchability of hatching eggs. This invention is suitable for large-scale breeding and hatching of breeding ducks.

The composting water-fertilizer integrated device comprises a box body, a composting layer, a water-fertilizer layer and a discharging port, the box body is divided into an upper layer and a lower layer, and the upper layer and the lower layer are connected through a stretching type hinge plate; a composting layer is arranged in the upper layer of the box body, compost body raw materials and fermentation strains are contained, organic fertilizer is generated after fermentation composting, and the device further comprises a blast ventilation system and a grid stirrer; the pH value and the temperature of the compost body are detected in real time through the pH sensor and the temperature sensor and are displayed through the data display screen; a water-fertilizer layer is arranged in the lower layer of the box body, after the stretching type hinge plate is opened, organic fertilizer falls into the water-fertilizer layer, clear water is injected through the water injection opening, water is injected according to the water-fertilizer proportion, water and fertilizer are stirred through the water-fertilizer stirrer, and water and fertilizer are produced at the discharging opening. According to the device, the composting water-fertilizer devices are connected in series, and the upper-layer fertilizer is quickly fed into the lower-layer fertilizer for water-fertilizer preparation by adopting the stretching type loose-leaf plate, so that the operation of transferring the fertilizer and adding water for stirring in the composting-water-fertilizer preparation process is solved, the fertilizer preparation period is shortened, and the time and the labor cost are saved.
