Abstract: Embodiments of the present disclosure provide a method for reduced-medicine treatment for post-harvest preservation of bayberries. The method includes: (1) packing after picking: placing ripe bayberries into a skeletonized injection-molded package after picking, the bayberries being spaced apart and evenly arranged in the skeletonized injection-molded package; (2) low-concentration peroxyacetic acid solution treatment: spraying a peroxyacetic acid solution with a concentration of 0.1% onto a surface of the bayberries; and (3) atmospheric plasma treatment: performing an atmospheric plasma treatment on the bayberries treated with the peroxyacetic acid solution for 5 minutes, and temporarily storing the bayberries in a refrigerated warehouse at 4° C. after the treatment. By combining peroxyacetic acid with atmospheric plasma, an amount of peroxyacetic acid solution used can be effectively reduced and efficacy of the treatment can be increased.

Abstract: The present invention discloses a fair task offloading and migration method for edge service networks, taking the Pareto optimality of the utility function of all user tasks executed by the edge system as the optimization objective, this approach not only takes into account the constraints of edge network resources, but also ensures the maximization of the utility function of all user tasks in the system, it proposes a new quantitative measurement index for improving the task utility quality under multi-user competition.

Abstract: A continuous quantitative spraying structure for sterilization of harvested fruits is provided. The continuous quantitative spraying structure includes a track provided thereon with equally spaced trays for conveying fruits, where the trays each include a circular tray body; a central part of the tray body is provided with a central hole allowing the fruit to fall off; a bottom part of the central hole is provided with two parallel rollers; an inner bottom surface of the tray body is provided with a flap; an inner end of a central shaft of the roller passes through the flap, and is fixed to a rolling wheel; a bearing is provided between the roller and the flap; the track is provided with a spraying sterilization section; the spraying sterilization section is sequentially provided with 3 to 4 sets of sterilization nozzles above a tray conveying route.
