The invention provides a feed additive for preventing a fatty liver of largemouth bass. The feed additive is prepared from the following raw materials in parts by weight: 15-22 parts of astragalus membranaceus, 13-20 parts of salviae miltiorrhizae, 4-8 parts of pericarpium citri reticulatae, 4-8 parts of fingered citron, 4-8 parts of citron, 7-12 parts of hawthorn, 3-6 parts of radix glycyrrhizae preparata, 5-8 parts of flos carthami, 4-6 parts of christina loosestrife herb, 4-6 parts of rheum officinale, 4-6 parts of herba artemisiae scopariae, 2-4 parts of curcuma aromatic, 4-8 parts of vitamin C, 3-5 parts of vitamin E, 3-6 parts of methionine and 1-3 parts of choline. The feed additive provided by the invention is capable of effectively preventing a fatty liver disease of the largemouth bass, so that frequent fatty liver phenomenon in a fish body when an artificial compound feed is used instead of fresh-frozen products in largemouth bass culture is solved; and an effective solving way is provided for healthy sustainable farming of the largemouth bass.

The invention discloses a ceramic plate for a cooking bench, and a preparation and application method thereof. The ceramic plate is composed of a billet and a glaze, wherein both sides of the billet are provided with slots for splicing; and the billet is prepared from kaolin, phosphogypsum, epoxy resin toughening emulsion containing modified bamboo fiber, quartz, feldspar and lime. The application method comprises the following steps: in the cooking bench table top laying or cooking bench integral body construction process, inserting inserts into the slots of the ceramic plate, or coating a tile adhesive layer in the slots of the ceramic plate and inserting inserts into the slots, thereby implementing splicing of the ceramic plates. The ceramic plate has the advantages of favorable toughness, favorable water resistance, favorable wear resistance and favorable self-cleaning performance. The application method is simple, can effectively reduce and even avoid the use of the tile adhesive, can obviously accelerate the construction schedule, and is suitable for constructing the cooking bench table top and cooking bench integral body.

An electric paddy field weeding machine comprises a handle, a push rod, a rechargeable motor, a rotating disc and a floating plate component. One end of the push rod is connected with a handle, the other end of the push rod is connected with a rotating shaft of the rotating disc, the rechargeable motor is connected with the rotating shaft through a transmission component and drives the rotating shaft to rotate, and the rotating disc is connected with the rotating shaft in the mode that the rotating disc does not move relative to the rotating shaft. The floating plate component is fixedly connected to one end of a rigid bow-shaped connecting piece, the other end of the bow-shaped connecting piece is connected to the rotating shaft through a bearing, and a plurality of hook tooth componentsprotruding out of the surface of the rotating disc are arranged on the rotating disc.

The invention discloses a method for removing bacterial contamination in fungi. The method comprises the following steps: (1) carrying out high temperature sterilization on a prepared fungus culture medium, pouring the sterilized fungus culture medium into a sterile culture dish, and cutting one or more than one small hole on a culture medium flat plate after the culture medium is solidified; (2)selecting samples in proper size and placing the samples in the small hole; (3) covering a sterile cover glass, and slightly pressing the periphery of the cover glass to make the cover glass closely contact with the culture medium so as to ensure that no air bubbles are left between the culture medium and the cover glass; (4) putting the culture medium obtained in the step (3) into a constant temperature and humidity incubator for culture; and (5) picking new fungus hyphae growing around the cover glass, and re-inoculating the fungus hyphae to a new fungus culture medium for culture, thereby obtaining fungus colonies. The invention has the advantages of excellent bacteria removing effect, no rebound, wide applicability, simple operation, small workload and short experimental period.

The present invention provides a transparent conducting layer for a heterojunction solar cell and a heterojunction solar cell. The transparent conducting layer comprises a conducting polymer layer including an opposite first surface and second surface. A one-dimensional conducting material located on at least one surface of the opposing surfaces of the conducting polymer layer or coated inside theconducting polymer layer. The invention reduces or even avoids the use of rare indium element with high valence, and can remarkably reduce the production cost; The process is simple, does not need high-priced vacuum equipment, does not need high-temperature process, more suitable for heterojunction batteries; At the same time, the light transmittance of the transparent conducting layer of the invention is equivalent to that of the existing indium oxide-based thin film, and the transparent conducting layer has high conductivity, so that the consumption of the metal electrode paste can be reduced; Compared with the existing indium oxide-based thin films, the cost is lower and the mechanical properties are better, which can be widely used in flexible devices.
