Novel long-acting alkaline compound fertilizer and preparation method thereof

Abstract: The invention relates to a novel long-acting alkaline compound fertilizer and a preparation method thereof, which are applied to the field of agriculture and forestry production. The novel long-acting alkaline compound fertilizer comprises long-acting stabilizer, soil conditioner and medium or trace elements. When the long-acting alkaline compound fertilizer is prepared, urea or ammonium chloride, monoammonium phosphate or diammonium phosphate, monopotassium phosphate, potassium nitrate, chelate iron, chelate manganese, chelate copper, chelate zinc, disodium octoborate tetrahydrate, calcium magnesium powder and the like are mixed according to a certain scientific proportioning, then are added with a certain quantity of plant nutrient conditioner and the long-acting stabilizer, are sufficiently mixed with the plant nutrient conditioner and the long-acting stabilizer, and then are granulated to form the novel long-acting alkaline compound fertilizer. A production process is simple, raw materials are easy to obtain, nutrient is comprehensive, nitrogen, phosphorus, potassium and the medium or trace elements are provided for soil and plants, the utilization rate of the fertilizer is improved effective, the pH (potential of hydrogen) of the fertilizer is larger than or equal to 7, and accordingly the fertilizer is suitable for acid soil, and has the advantages of improving the soil and preserving an ecological environment.

Regenerating agent for water softening apparatus

Abstract: PURPOSE:To regenerate a cation-exchange body in a water softening apparatus into a potassium-type body when the body is regenerated and to obtain potassium ion-contg. soft water by preparing the regenerating agent for the water softening apparatus from a potassium ion-releasing electrolyte such as potassium chloride. CONSTITUTION:The regenerating agent for the water softening apparatus is prepared from a potassium ion-releasing electrolyte such as potassium chloride, potassium sulfate, potassium nitrate, potassium phosphate, potassium carbonate, potassium acetate, and potassium tartrate. When the water softening apparatus is used for a long period, iron rust and scales are deposited on the cation-exchange body in the apparatus, and the iron rust and scales can be removed with a common regenerating agent. However, when a water-soluble oxidizing agent is incorporated into the regenerating agent, the iron rust and scales can be efficiently removed. An alkyl metallic salt of peracid such as potassium percarbonate and a halogen acid salt such as potassium hypochlorite are used as said water- soluble oxidizing agent.

Leaf vegetable water planting nutrient solution and preparation method thereof

Abstract: The invention belongs to vegetable water planting nutrient solutions, and in particular discloses a leaf vegetable water planting nutrient solution and a preparation method thereof The leaf vegetable water planting nutrient solution is prepared from effective amounts of calcium nitrate, potassium nitrate, monopotassium phosphate, magnesium sulfate, ferrochel, sodium nitrate, boric acid, sodium molybdate, zinc sulfate, manganese sulfate and sodium chloride which are dissolved in water and are compounded together By adopting the leaf vegetable water planting nutrient solution, the problems that conventional water planting vegetable is high in both production cost and nitrate content are solved, and the leaf vegetable water planting nutrient solution has the advantages that the nutrient solution is easy to prepare and low in cost, various biological indexes and qualities of planted water planting vegetables are remarkably prior to those of control groups, the content of nitrate meets the national standard and the standard of green pollution-free vegetables, and the like
