Problems solved by technology

Rice planting requires nutrient-rich fertilizers, mainly nitrogen, phosphorus, and potassium. If there is nitrogen deficiency, symptoms such as leaf volume reduction and yellowing will occur. Phosphorus deficiency will cause the leaves to turn dark green and the plant will have fewer tillers. Potassium deficiency will cause There are symptoms of short plants and red spots on the top, but in the actual planting process, growers often use fertilizers in pursuit of cost, apply a large amount of chemical fertilizers, and the fertilizer formula is chaotic, the application effect is poor, and it pollutes the environment

Abstract

The invention discloses a preparation method of a safe and environment-friendly fertilizer special for rice. The preparation method comprises the following steps: uniformly mixing ammonium bicarbonate, ground phosphate rock, potassium polyphosphates, defluorinated phosphate, zinc humate, borax, calcined clay, vermiculite power, coconut shell charcoal powder and expanded perlite to obtain a first material; uniformly mixing collagens, polylactic acid, activated palygorskite and water, adding polyvinyl alcohol and glyoxal, regulating the pH value of the system to be 10-10.8 with sodium hydroxide,raising the temperature, and stirring to obtain a second material; and uniformly mixing pond sludge, manioc wastes, citric acid residues, distillers' grains, tea seed cake, meat and bone meal and bombyx mori, regulating the moisture content, grinding, adding the first material to be uniformly mixed, irradiating by an ultraviolet lamp, homogenizing, adding cellulase for enzymolysis, adding bifidobacterium for performing anaerobic fermentation, adding the second material for granulating, drying, and cooling, thereby obtaining the safe and environmental-friendly fertilizer special for rice.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a method for preparing a safe and environment-friendly special fertilizer for rice. Background technique [0002] In addition to being edible, rice can also be used for starch production, wine making, vinegar production, rice bran can be used for sugar production, oil extraction, furfural extraction, etc. Rice straw is a good feed, papermaking raw material, and weaving material, and rice buds and rice roots can be used for medicine . Rice planting requires nutrient-rich fertilizers, mainly nitrogen, phosphorus, and potassium. If there is nitrogen deficiency, symptoms such as leaf volume reduction and yellowing will occur. Phosphorus deficiency will cause the leaves to turn dark green and the plant will have fewer tillers. Potassium deficiency will cause There are symptoms of short plants and red spots on the top. In the actual planting process, growers often apply fertilizer...
