Abstract

The invention belongs to the fertilizer field and discloses an effect-increasing loss-control agent for fertilizers and a preparation method thereof. The agent is composed of a nitrogen nitrification inhibitor, a biological fermentation compound amino acid, a soil conditioner, an active-layer-shaped phyllosilicate and a compound microelement, wherein the nitrogen nitrification inhibitor can control resolution drain of ammonium nitrogen; the biological fermentation compound amino acid can absorb ammoniacal nitrogen, reduce volatilization loss, and stimulate plant root growth and absorption and utilization of nutrients; the soil conditioner can free soil, increase granular structure of the soil, form a net structure with the active-layer-shaped phyllosilicate through and bridging to reduce fertilizer nutrient loss, absorb and exchange NH4+ and K+, and improve the breathability, water-retaining property and nutrient-retaining property of the soil, therefore the nutrient utilization is improved, the nitrogen loss is reduced, and the effectiveness of the nitrogenous fertilizer is improved. Potted plants and field fertilizer efficiency tests show that the agent can improve the fertilizer nutrient utilization remarkably and increase the volume and income of crops.

Description

technical field [0001] The invention belongs to the field of fertilizers, and in particular relates to a 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 ammonium salt a...
