Abstract

The invention discloses a preparation for inhibiting soil nitrogen loss as well as a preparation method and an application thereof. The preparation is prepared from the following raw materials in percentage by mass: 1-40% of 2-chloro-6-trichloromethylpyridine, 0-5% of hydroquinone, 5-20% of accessory ingredient and 35-90% of solvent. The preparation disclosed by the invention can be evenly dispersed in an aqueous phase, and the preparation and a nitrogenous fertilizer are evenly applied into soil so as to effectively alleviate speed of urea to be hydrolyzed into ammonia under the urease action and also effectively inhibit the process of oxidizing NH<4+> into NO<3->; NO<2-> and NO<3-> leaching loss is reduced, and NOX and N2 can be further prevented from escaping because of denitrification; and the utilization rate of the nitrogen fertilizer is improved so as to improve the quality and the yield of the crops and lighten pollution to environment by the nitrogen fertilizer.

Description

technical field [0001] The invention relates to a preparation for inhibiting soil nitrogen loss, a preparation method and application thereof. [0002] Background technique [0003] Nitrogen in soil is divided into organic nitrogen and inorganic nitrogen. Organic nitrogen mainly comes from animals, fish products, green manure, crop residues, organic chemical fertilizers, etc. Except for organic nitrogen chemical fertilizers such as urea, these organic nitrogen fertilizers have very low solubility in water and cannot be directly absorbed and utilized by plants. Nitrogen in organic nitrogen-containing compounds is only useful to plants when they are converted by soil microorganisms into inorganic nitrogen-containing compounds. After this organic nitrogen-containing compound is decomposed by microorganisms, ammonia or ammonium salts are first generated. For example: urea first generates ammonia under the action of soil urease, [0004] Due to this rapid change in the ...
