The invention provides a comprehensive method for soil conditioning and restoration. The method comprises the following steps: before crops are planted or after fruit trees are harvested, oyster shellpowder, silicon-calcium-potassium-magnesium fertilizer, biological organic fertilizer, a biological control agent and ternary compound fertilizer are applied to soil; before the fruit trees are sprouted and bloomed, a macroelement water-soluble fertilizer and humic acid water-soluble fertilizer are applied to the soil; during a swelling period of young fruits of the fruit trees, silicon-calcium-potassium-magnesium fertilizer and a composite microbial bacterial liquid are applied to the soil; and during a fruit strengthening period of the fruit trees, high-potassium fertilizer and seaweed fertilizer are applied to the soil. The method is used for conditioning and restoring the soil, so that the pH of the soil tends to be neutral, and the acidification degree is obviously reduced; the organic matter content of the soil is obviously increased, the soil becomes loose and breathable, and the soil layer is deep and thick; and the heavy metal content in the soil is reduced, so that securityof the planted crops is improved, and the yield is improved. The method provided by the invention does not interrupt growth of the crops in the soil, enables the crops to grow healthily while conditioning and restoring the soil, and improves quality of the crops, so that economic benefits of growers are guaranteed.

The invention discloses a preparation method of a ginsenoside extract for a beverage. The preparation method aims to solve the technical problems that a current ginsenoside extract is prone to being turbid after being dissolved in water and is difficultly applied to addition in the beverage with a certain requirement for clarity. The preparation method comprises the approximate steps: ginsenosidein raw ginseng is subjected to liquid extraction firstly, and grease in ginsenoside extraction filtrate is removed through diatomite; then insoluble tiny impurities in the ginsenoside extraction filtrate are removed by filtering through a three-stage filtration system; and finally, spray drying is conducted, by combing the difference between the molecular weight of proteins and the molecular weight of the ginsenoside and ultrafiltration membrane separation, the unstable macromolecular proteins are separated, and thus the ginsenoside extract with high solution stability is obtained. A clarifiedsystem can be formed by the ginsenoside extract obtained through the preparation method and a solution, thus it is ensured that the obtained ginsenoside extract has the great solution stability, theapplication concentration of the ginsenoside in the beverage is greatly increased, and the stability of the ginsenoside in the beverage is greatly improved.

An ophthalmic composition characterized by comprising (A) vitamin A, (B) a polyoxyethylene polyoxypropylene glycol, and at least one component selected from (C) trometamol, (D) polyhydric alcohols, (E) saccharides, (F) phosphoric acid and salt thereof and (G) monovalent neutral salts.

The invention discloses a sewage treatment device provided with an anti-blocking mechanism and used for environmental protection, and belongs to the technical field of sewage treatment. The sewage treatment device comprises a box body, the upper and lower surfaces of the inner wall of the box body are fixedly connected with the surface of a shell, and the inner wall of the shell is fixedly connected with the surface of a sub-sink bin; the inner wall of the sub-sink bin is clamped with a plurality of partition plates. According to the sewage treatment device provided with the anti-blocking mechanism and used for environmental protection, by arranging a sludge discharge pipe and a flow collecting pipe, when internal sediments and sludge need to be discharged, a water discharge pipe is opened, and then the sludge is discharged through the sludge discharge pipe; then a floating block blocks the bottom end of the flow collecting pipe under the action of the elastic force and buoyancy of a spring, sewage discharging can be completed, meanwhile, automatic closing is conducted after sewage discharging is completed, then the sludge discharge pipe is closed, in this way, stable cleaning of internal sludge can be kept, and meanwhile, internal stable discharging can be kept in cooperation with the counterclockwise circulating sedimentation mode; and meanwhile, the device can automaticallystop to prevent internal sewage from flowing out after sewage discharge is finished.

A water-based long-acting antirust agent, which is composed of C8~C10 carboxylate (sodium, potassium or ammonium salt, 5.0~30.0%), ethanolamine (one, two or triethanolamine, 5.0~15.0%), boric acid (boric acid or ammonium borate, 3.0-8.0%) polyethylene glycol (8-10 ethylene glycol polymerization degree, 0.0-5.0%). The product is light yellow transparent viscous liquid. The antirust agent can dissolve the raw material in water at normal temperature or under heating. The antirust agent has a good protective effect on general carbon steel and cast iron. When used, no white spots will be formed on the metal surface, no flow marks and the original color of the metal surface will be maintained; there will be no change in the damp heat test period of more than 4 weeks. The anti-rust agent has good stability and can remain stable under high and low temperature conditions without stratification or precipitation. The product and raw materials are safe, and it has no harm to the human body and no pollution to the environment when it is prepared and used. It is an environmentally friendly and pollution-free long-term metal rust inhibitor.
