The invention discloses a seedling cultivation method for a wild fruit kadsurae coccinea (Lem.)A.C.Smith. The method comprises the steps of: settling a nursery garden; selecting a seed source; cultivating seeds; carrying out cutting and seedling and the like. The seed germination rate of kadsurae coccinea (Lem.)A.C.Smith can reach over 90%, and the cutting survival rate can reach over 55%. According to the method disclosed by the invention, the artificial cultivation success rate of the wild fruit kadsurae coccinea (Lem.)A.C.Smith can be improved, scaled planting of the wild fruit kadsurae coccinea (Lem.)A.C.Smith is realized, and the method has good market development prospect and economic benefit.

The invention discloses a graphene micro-nano laminated phase change material energy-saving louver, which comprises a bottom beam, a plurality of phase change material louver blades, a louver lifting rope, a ladder rope and a top beam, wherein the plurality of phase material louver blades are suspended under the top beam through the ladder rope, the bottom beam is suspended at the lowest end of the lowest phase change material louver blade through the ladder rope, certain gap intervals are arranged among the phase change material louver blades to bring convenience to adjusting inclined angles and light transmittance of the phase change material louver blades, the phase change material louver can be collected up or put down by pulling the louver lifting rope, the phase change material louver blades are prepared from graphene and a phase change material through a micro-nano laminating technology, the graphene and the phase change material are evenly arranged in a laminated mode, and the surface is wrapped by a thin high-polymer protection layer. The louver disclosed by the invention has a traditional light shielding function, stores light energy at the same time, can release heat in necessary, can adjust indoor temperature to reduce use of an air conditioner and achieves effects of saving energy and reducing emission.

The present invention discloses a high-yield cultivation device of cichlids. The device comprises a box body, the box body is internally provided with a plurality of oppositely arranged isolation plates, the isolation plates are provided with a plurality of through holes, the box body is internally provided with a vent plate, the vent plate and the box body form a vent layer, the isolation platesare located at the vent plate, the surface of the vent plate is provided with a plurality of uniform air holes, the air holes are internally provided with stop brushes, one end of the vent layer is provided with an air pump, the air pump communicates with the vent layer through a pipeline, the vent layer is internally provided with a stop plate, the stop plate is provided with a sinking pump, thestop plate is employed to divide the vent layer into a water inlet area and a water outlet area, the water inlet end of the sinking pump communicates with the water inlet area, the water outlet end ofthe sinking pump communicates with the water outlet area, the through holes on the isolation plates are different in size, and the isolation plates are arranged in order from big to small according to the sizes of the through holes in a direction from the water outlet area to the water inlet area. The high-yield cultivation device of cichlids can perform spontaneous regulation and control for theactivity range of the cichlid seedlings according to the sizes so as to reduce the internal friction generated in the internal fighting and improve the high-yield cultivation of the cichlids.
