Ecological nitrogenous fertilizer and preparation method thereof

Abstract

The invention discloses an ecological nitrogenous fertilizer and a preparation method thereof. The ecological nitrogenous fertilizer comprises raw materials of, by weight, 60-80 parts of urea, 13-15 parts of ammonium chloride, animal hair, 5-7 parts of feathers, 20-30 parts of peat, 14-16 parts of modified pot clay, 0.6-0.8 part of zinc sulphate monohydrate, 0.2-0.4 part of micronutrients fertilizers, 3-8 parts of ferrous sulfate, 23-28 parts of chitin, 2-4 parts of modified nanocarbon, 2-4 parts of white poplar barberry root barks, 2-4 parts of lavender, 4-6 parts of paulownia barks, 3-5 parts of herbs of wilson passionflowers and 2-4 parts of Chinese wisteria. The feathers and the like are subjected to acid hydrolysis to generate amino acid, secondary and trace elements are subjected to chelation, a chelation structure of carboxymethylcellulose is added, effective utilization of the secondary and trace elements is facilitated, and invalid release of the secondary and trace elements is reduced; the white poplar barberry root barks, the lavender, the paulownia barks, the herbs of wilson passionflowers and the Chinese wisteria are added, so that pest and disease damage to soil is effectively reduced; and the ecological nitrogenous fertilizer is capable of obviously improving the fertilizer efficiency use ratio, the ecological nitrogenous fertilizer is only required to be applied for one time and then slowly and effectively released, frequency of fertilizer application can be reduced, fertilizer costs are reduced, and economic benefits are improved.

Description

technical field [0001] The invention relates to an ecological nitrogen fertilizer and a preparation method thereof. Background technique [0002] At present, the nitrogen fertilizers commonly used by farmers are mainly urea and ammonium bicarbonate. Due to their unstable chemical properties and unreasonable use, the utilization rate of urea and ammonium bicarbonate is very low, resulting in waste of resources and energy and pollution to the environment. Urea is the most important type of nitrogen fertilizer, accounting for more than 60% of the total nitrogen fertilizer. Urea is an amide nitrogen fertilizer with a nitrogen content as high as 46%. It does not compact, salinize, or acidify the soil, and is suitable for a variety of crops and soils. However, after being applied to the soil, some of them are converted into nitrate nitrogen or gaseous nitrogen and are easily lost. The utilization rate of urea in the current season is generally only about 30%. Improving the utili...
