Abstract: An ecological restoration method for seawater back-flowing farmlands in a tropical region includes the following steps: performing soil ridging on a seawater back-flowing saline-alkalized land by using a whole-mulching double-ridge model thereof, a ridge body that has been ridged is a trapezoidal structure, and perpendicular to a direction of a coastline; planting a salt-tolerant plant on ridges, and planting Acanthus ilicifolius in furrows. Salts on the ridges are rinsed into the furrows by means of natural precipitation and irrigation; the Acanthus ilicifolius that have been planted in the furrows excretes redundant salts by using salt glands; the salt-tolerant plant and the Acanthus ilicifolius are harvested to effectively remove salts, thereby achieving an effect of reducing salts in soil by a dual-function of the ridges and the furrows.

Abstract: An array substrate and a manufacturing method therefor, and a display panel are provided. The manufacturing method includes: forming a scan line and a gate on a substrate; forming a first insulating layer covering the scan line and the gate on the substrate; forming a metal oxide semiconductor layer above the first insulating layer, the metal oxide semiconductor layer including a source, a drain and an active layer; coating an upper surface of the metal oxide semiconductor layer with a photosensitive material layer; photoetching the photosensitive material layer from the back side of the substrate by using a first metal layer as a mask to form a channel protection layer; performing conductorization treatment on the metal oxide semiconductor layer to enable the source and the drain to be conductive; forming a data line above the first insulating layer; and forming a pixel electrode above the first insulating layer.

Abstract: A use of a polypeptide in a drug for preventing and treating pneumonia is provided. The polypeptide may effectively prevent and treat pneumonia, and may also be added with another therapeutic agent, excipient, carrier, or auxiliary ingredient to prepare a drug with the polypeptide and the therapeutic agent as main active ingredients for preventing and treating pneumonia. The present invention further discloses a use of the polypeptide and a drug thereof in prevention and treatment of pneumonia. The drug has good inhibitory and treatment effects on pneumonia, may effectively act on pneumonia caused by pathogenic bacteria for effective prevention, and may also improve a treatment effect on pneumonia. Compared with the prior art, the polypeptide and the drug thereof have effects of high safety and no drug resistance, can effectively prevent and treat pneumonia, and have high-value application prospects.
