The invention belongs to the technical field of heavy metal polluted farmland soil environment treatment, and discloses a method for reducing the arsenic content in rice in an acid arsenic polluted rice field and application. According to the method, a proper amount of sodium persulfate is applied before rice transplanting or planting, calcium magnesium phosphate fertilizer, ammonium bicarbonate and urea base fertilizer are applied in a matched mode, meanwhile, reasonable moisture management or moisture adjustment is conducted in the whole growth period, absorption and accumulation of arsenic by rice can be effectively reduced, the arsenic content in rice is lower than the national pollutant limit standard in food, and the yield of rice is increased. And the target of safe production is achieved. In addition, compared with a traditional soil treatment method, the method is small in work amount, the applied raw materials are low in cost, the application method and technical management are ...

The invention discloses a special tool for disassembling and assembling a static contact spring of a disconnecting switch. The special tool comprises a motion arm, a front hook and a pressing block, wherein the rear end of the front hook is hinged on the front end of the motion arm, and a hook point on the front end of the front hook is inwards formed; the upper end of the pressing block is hinged on the front part of the motion arm, and the middle part of the lower end plane is outwards protruded to form a rectangular boss. The width of the boss is equal to a distance between two adjacent contact fingers on the static contact of the isolating switch. According to the special tool for disassembling and assembling the static contact spring of the disconnecting switch provided by the invention through a lever principle, a worker can save more energy while performing the work and finishing the work independently, and the working time is short, most importantly, the tensile strength on the ...

The invention belongs to the field of agricultural surface pollution treatment, and discloses a leaf surface regulating agent and application thereof to reduction of arsenic content in rice. The nanoscale sol leaf surface regulating agent formed by cementing sodium tripolyphosphate and hydrogen peroxide degraded chitosan is used for treating arsenic-polluted rice leaves, and can regulate and reduce the absorption and transportation of arsenic in the rice in the filling stage, increase the content of arsenic in rice husks and leaves and reduce the transportation of arsenic to grains in soil, so that the content of arsenic in rice is reduced.
