Abstract

The invention belongs to the field of fertilizers and discloses a synergistic loss-control agent of nitrogenous fertilizers and a production method thereof. The synergistic loss-control agent is composed of a nitrogen stabilizer, a bio-surfactant, biological fermentation compound amino acid, a plant growth regulator, a soil structure modifier and water, wherein the nitrogen stabilizer can control nitration, decomposition and loss of ammonium nitrogen; the biological fermentation compound amino acid can absorb and chemically combine the ammonium nitrogen and reduce volatilization loss; plant growth regulator, the plant growth regulator can regulate plant growth and promote plants to absorb nitrogen, phosphor, potassium and microelements; the soil structure modifier can loosen soil and add granular structures of the soil; and the bio-surfactant can promote the plants to absorb nutrients and improve the utilization rate of the nutrients, therefore loss of phosphate is reduced, and effectiveness of the phosphate fertilizers is improved. Potting and field fertilizer efficiency tests show that the utilization rate of the phosphate can be improved obviously and the yield of crops and income can be increased through the synergistic loss-control agent.

Description

technical field [0001] The invention belongs to the field of fertilizers, and in particular relates to a nitrogen fertilizer synergist and loss control agent and a preparation method thereof. Background technique [0002] Plant growth requires a variety of nutrients. Among them, the macronutrient elements required for crop growth include carbon, hydrogen, oxygen, nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur, and the micronutrient elements include boron, copper, iron, manganese, molybdenum, zinc, and chlorine. Nitrogen is one of the three essential nutrients for plants and plays a very important role in crop growth. It is a component of amino acids in plants, a component of protein, and a component of chlorophyll that plays a decisive role in photosynthesis in plants. . [0003] There are two main forms of nitrogen uptake by crops: inorganic nitrogen and organic nitrogen. Among them, the inorganic nitrogen absorbed by crops from the soil is mainly ammoni...
