The invention provides a potential drug for anti-white spot syndrome virus in aquaculture, which can efficiently and quickly inhibit the replication of WSSV, and has a wide range of applications, not only for the Penaeus japonicus and blue crabs that are cultured in seawater, but also for Procambarus clarkii cultured in freshwater. The small RNA antisense nucleic acid AMO-miR-9875 of the present invention has a small molecular weight and is easy to degrade, will not destroy the ecological balance of marine farming, and will not cause harm to the human body. It is an environmentally friendly and effective virus defense substance.

The invention discloses a plant bacteriostasis method adopting the bacillus methylotrophicus strain NKG-1. Pesticide is prepared from bacillus methylotrophicus strain NKG-1 bacteria liquid, and the prepared pesticide methylotrophicus agentia is applied in the growing period of plants to inhibit germs on the plants. By the adoption of the plant bacteriostasis method adopting the strain, various pathogenic fungi and bacteria can be inhibited, a good control effect is realized, and therefore application prospects are broad.

The invention provides a method for extracting soluble salt in soil. The method comprises the following steps: a land to be treated is prepared into ridges with a preset specification; a dialysis tube is laid in each ridge, wherein the dialysis tubes are tubes with micropores distributed all over the tube walls, and the vertical distances from the axial centerline of the dialysis tube to all surfaces of the ridge are equal; the dialysis tubes are connected to a water delivery pipe communicating with a water source through pipe parts, such that a dialysis tube network is formed; the water source is turned on, and water is supplied for the dialysis tube network, such that a cylindrical moist body with length equal to that of the dialysis tube and with the dialysis tube as an axis is formed in each ridge; water flow in the moist bodies brings soluble salt in the soil in the ridges to the surface of the ridge soil, and the water source is turned off when the salt content in the soil in the ridges meets a preset salt content threshold; and the soluble salt at the surface of the ridge soil is extracted with a preset method. Therefore, on the bases of low cost and environment-friendliness, the soluble salt is extracted from soil, and soil soluble salt content can reach the standard for a normal arable land.

A rotational disk mechanism for treating water by photocatalytic and biological method is composed of rotary shaft and blade wheel fixed to said rotary shaft.
