Abstract: The present invention belongs to the technical field of biological fermented feeds, in particular to a two-step production method of a mycoprotein biological feed by fermenting corn husks. The present invention provides a preparation method for a mycoprotein biological feed, which comprises: inoculating Aspergillus niger microbial agent on a first fermentation substrate for first fermentation, to obtain a yeast seed; and inoculating a compound microbial agent in a second fermentation substrate to perform second fermentation. The compositions of the first fermentation substrate, the second fermentation substrate and the compound microbial agent are defined. The degradation of cellulose and hemicellulose in the corn husk raw material can be maximized and the protein content is increased through two fermentations, while taking into account the cost.

Abstract: The invention discloses an energy self-control base station for battery replacement based on solar power supply with independent UAV take-off and landing, which comprises a UAV take-off and landing device, an automatic battery replacement device and an energy supply device. The foldable solar panel structure is driven by a motor. The invention has simple structure and is convenient for automatic battery replacement. The UAV damage caused by UAV position deviation is effectively avoided when the platform descends. The invention adopts an electric mechanical claw to cooperate with a liftable battery compartment, so as to automatically replace UAV batteries. After the electric mechanical claw is aligned with the predetermined position, the batteries can be grasped and placed by lifting the battery compartment or the annular lifting platform, which simplifies the mechanical structure of the automatic battery replacement device.
