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.

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.
