This invention discloses a high-humicity microbial fertilizer and its preparation method, belonging to the field of microbial fertilizer technology. The method involves adding a mixed carrier, a protective agent, and fermentation broth to a stirred tank in a specific ratio, followed by shaking and adsorption, filtration, and drying with forced air until the moisture content of the absorbent resin powder reaches 30-35%. The powder is then continuously granulated using a granulator and sieved to obtain microbial agent granules with a particle size of 2-5 mm. The microbial agent granules and sodium humate are mixed at a mass ratio of 1-2:10 to obtain the high-humicity microbial fertilizer. The aggregated short fibers, under the adhesive and physical entanglement effects of the protective agent, increase the internal space of the microbial agent granules while improving structural stability, providing a stable growth and reproduction environment for microorganisms, and improving the long-term storage of the fertilizer and the survival rate of microorganisms after application. The enlarged microbial agent granules provide support, increasing soil looseness and providing a good respiratory environment for crop roots.

This utility model discloses a water-saving seedling box based on a support medium for wheat germination detection. The box body is composed of a support frame and transparent splicing panels to ensure light penetration. The box contains multiple layers, each with seedling troughs filled with sponge. A liquid level sensor is installed on one side of each trough to monitor water volume in real time. A spray pipe with a sprinkler head is installed above the troughs, and a drain outlet is opened on one side at the bottom, connected to a water collection tank at the bottom of the box via a drain pipe to drain excess water and prevent flooding of the wheat seedlings. The water collection tank has an overflow outlet and a debris preventer to prevent impurities from entering. The water collection tank is connected to a water supply pipe via a water pump to achieve water recycling. In addition, a water collection component is installed on the top of the box to collect rainwater. This utility model, through its drainage, water recycling, and rainwater collection designs, effectively avoids water accumulation problems, achieves water conservation and efficient utilization, and provides a good seedling environment for wheat germination detection.

The utility model discloses a support for intraoperative breathing of infusion port implantation patients, which comprises an upper cover, a coaming, an inflatable neck pillow and a bottom plate, the coaming is slidably mounted on one side of the top of the bottom plate, and the coaming and the bottom plate are positioned through a knob; an upper cover is detachably installed on the top of the surrounding plate through a handle, and an inflation neck pillow is further connected to the top of the bottom plate in a sliding mode. The device can be adjusted according to different head sizes, heights and lying positions of different patients, the comfort level of the patients can be guaranteed, the universality is high, by arranging the upper cover, in an infusion port operation, arms of doctors need to be supported, operation fatigue is relieved, the comfort level of the doctors is improved, and the requirement for operation implementation is met; meanwhile, the upper cover and the coaming are not totally closed, the breathing environment of the infusion port patient can be improved, the oppression and fear of the patient are avoided and relieved, intubation implementation is facilitated, and the safety feeling of the patient is improved.
