Urea ammonium nitrogen fertilizer and preparation method thereof

Abstract

The invention relates to the field of fertilizers and in particular relates to a urea ammonium nitrogen fertilizer and a preparation method thereof. The method comprises the following steps: mixing and stirring 30-50wt% of urea, 5-25wt% of ammonium sulfate, 40-50wt% of ammonium chloride and 5-15wt% of adhesive, stirring for 20-40 minutes, obtaining a mixture, and granulating to obtain the urea ammonium nitrogen fertilizer. The preparation method is simple and low in cost, and the product has the advantages of high utilization rate, rapid and long-term effect, enzyme supplement, disease prevention and comprehensive nutrition.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a urea ammonium nitrogen fertilizer and a preparation method thereof. Background technique [0002] The growth of crops needs to absorb a lot of nutrients from the soil, and the soil in the farmland has been planted for years, and the nutrients are absorbed by the crops. In order to ensure that the crops have sufficient nutrients, the farmland must be fertilized to supplement the nutrients that the farmland lacks. , the general method is to supplement the soil with mineral nutrients, nitrogen and organic matter in the form of fertilizers. However, due to the extensive use of general chemical fertilizers, the soil structure is destroyed, the physical and chemical properties are deteriorated, and the production potential is reduced. Ecological The environment is fragile, and what is more serious is that the utilization rate of chemical fertilizers is too low, and the soil, environment, a...
