This invention discloses a method for improving soil in potato cultivation, belonging to the field of agricultural soil remediation technology. Addressing the problems of soil acidification, compaction, reduced beneficial microorganisms, and severe soil-borne diseases caused by continuous potato cropping, this invention provides a synergistic improvement method integrating soil pretreatment, coupled application of microbial agents and organic fertilizers as basal fertilizers, dynamic and precise regulation throughout the growth cycle, coordinated water and fertilizer management, and post-harvest remediation. This method involves basal application of a specific ratio of compound microbial agents coupled with organic fertilizers. Based on the physiological needs and disease occurrence patterns of potatoes at different growth stages, and combined with the dynamic and precise regulation of the timing and dosage of microbial agent application through a drip irrigation system, water and fertilizer supply are simultaneously optimized, achieving synergistic effects of biological antagonism, soil ecological restoration, and crop nutrient regulation. This invention effectively improves the soil micro-ecological environment, reduces the incidence of soil-borne diseases, reduces reliance on chemical fertilizers and pesticides, and improves potato yield and quality.

The application discloses a nerve tumor surgery postoperative rehabilitation nursing device, and relates to the technical field of nerve tumor surgery, which comprises a nursing helmet, and an air bag neck ring is arranged at the bottom of the nursing helmet. The nerve tumor surgery postoperative rehabilitation nursing device can continuously cool the top of the head of a patient, so that the wound site is kept in a dry state at all times, a good nursing and healing environment is provided for the rapid recovery of the wound site, the head of the patient is helped to dissipate heat in a large area, the feeling of stuffiness and discomfort of the head caused by long-time wearing of the nursing helmet is eliminated, the wound site is prevented from being excessively pressed, a child lock mode is provided, direct scratching of the wound site by the hands of children is effectively prevented, the normal recovery of the wound site is protected, wound healing is accelerated, scarring is prevented, automatic diffusion type medicine application wet nursing effect on the wound site of the head of the patient is realized, and slow medicine application on the wound site is realized.

The utility model relates to the related technical field of fermentation devices, in particular to a fermentation mixer for microbial fertilizer production, which comprises a base, a stand column is fixedly mounted on the upper surface of the base, a discharge hopper is fixedly connected to the upper end of the stand column, and a heat preservation layer is fixedly mounted at the upper end of the discharge hopper. An inner ring of the heat preservation layer is fixedly connected with an inner-layer tank body, a high-frequency electromagnetic coil is arranged on the surface of the inner side of the heat preservation layer, the upper end of the inner-layer tank body is sleeved with a sealing ring, the inner-layer tank body is connected with the sealing cover through the sealing ring, and a paraffin-based phase change material with the melting point being 55 DEG C is arranged in the heat preservation layer. Temperature fluctuation is accurately controlled through melting heat absorption and solidification heat release, compared with a traditional solid structure, thermal resistance is improved, extra heating or cooling equipment is not needed when an extreme temperature difference is coped, a high-frequency electromagnetic coil is matched for direct induction heating of the tank body, and the local overheating problem of resistance heating is avoided; and the problem of inactivation of low-temperature functional bacteria caused by out-of-control temperature in a high-temperature stage is solved.

The utility model relates to the technical field of gypsum board packing devices, and provides a gypsum board packing machine head which comprises a mounting plate, two rod seats fixedly arranged on the outer surface of the mounting plate, a second lead screw rotationally connected to the outer surface of one rod seat, and a limiting rod fixedly arranged on the outer surface of the other rod seat. The device is provided with a structure for adjusting the distance between the machine head and the film covering and packaging mechanism according to the size of the gypsum board, when facing the gypsum boards of different sizes, the adjustable structure can be flexibly adapted, and for the gypsum boards of small sizes, the adjustable structure can be flexibly adjusted. The distance between the machine head and the film covering and packaging mechanism is proper through adjustment, the film covering and packaging mechanism can be tightly attached to the gypsum board, slipping in the transportation and storage process is prevented, the product integrity is guaranteed, the distance is reasonably adjusted for the large-size gypsum board, excessive pressing of the machine head on the gypsum board is avoided, and the gypsum board is prevented from being damaged and cracked; it is ensured that the film covering and packaging mechanism normally plays a role, and packaging operation is smoothly completed.
