Problems solved by technology

Simply applying a large amount of nitrogen, phosphorus, and potassium will gradually reduce the trace elements in the soil, and the absorption effect of crops on nitrogen, phosphorus, and potassium nutrients will become worse and worse. In some areas, the limiting factor for crop high yield, that is, the minimum nutrient is no longer nitrogen. The three elements of phosphorus and potassium, but the lack of trace elements such as calcium, magnesium, zinc, boron, etc., because crops absorb various nutrients in a ce

Abstract

The invention discloses an alginic acid containing compound fertilizer with a urease inhibiting effect and a production method of the fertilizer. The fertilizer is characterized by being prepared from the following ingredients in parts by weight: 42-48 parts of urea, 20-24 parts of diammonium phosphate, 18-22 parts of potassium sulfate, 10-12 parts of alga synergia liquid, 30-34 parts of sulfuric acid, 14-16 parts of liquid ammonia, 3-5 parts of microelement fertilizer, 1.2-1.6 parts of dolomite dust, 2-4 parts of citric acid dissolved magnesium oxide, 0.8-1.2 parts of abamectin and 0.06-0.08 parts of plant growth regulators. The obtained fertilizer has the urease inhibiting effect and an excellent slow release effect, can be degraded by microorganisms completely, supplements nitrogen phosphorus kalium complex elements required by plant growth, provides rich nutrients scarce in soil, has significant insecticide and insect prevention effects, increases the yield of a crop, is simple in production process, and facilitates industrialized production.

Description

technical field [0001] The invention belongs to the technical field of compound fertilizers, and in particular relates to a compound fertilizer containing alginic acid with urease inhibitory effect and a manufacturing method thereof. Background technique [0002] Fertilizer synergist, in simple terms, is a type of product that improves the utilization rate of chemical fertilizers. It refers to improving fertilizer efficiency, reducing fixation, volatilization, leaching, runoff, increasing fertilizer effect and nutrient contribution rate, facilitating absorption and transformation, prolonging fertilizer effect period, improving or repairing soil, adjusting soil fertilizer supply and retention capacity, and improving crop quality. Fertilizer supplementary products, known as "companions", "synergists", "synergists", etc. [0003] Compound fertilizers have played an important role in agricultural development, increasing production and saving production costs. How to improve the...
