Abstract

The invention discloses a powder element fertilizer as well as a preparation method and application method thereof. The method is characterized by comprising the following steps: uniformly mixing a soluble trace element fertilizer, a citrate-soluble trace element fertilizer, an acidifier and an anticaking agent to obtain a mixture, grinding and screening the mixture until the particle size is less than 150 meshes, thereby obtaining the powder trace element fertilizer; and coating seeds or other granular fertilizers with the powder trace element fertilizer. Compared with the prior art, the technique enhances the dispersion uniformity of the minor elements in soil and the absorption and utilization efficiency of the seeds for the minor elements, implements unification of the short-term fertilizer efficiency and long-term fertilizer efficiency, and reduces the problem of caking of the powder product in the use process.

Description

technical field [0001] The invention relates to a powdery trace element fertilizer, a preparation method and a use method, and belongs to the technical fields of soil chemistry and fertilizer manufacturing. Background technique [0002] In the existing market, trace element fertilizers are mostly used after granulation. However, unlike macronutrient fertilizers such as nitrogen, phosphorus, and potassium fertilizers, micronutrient fertilizers are used in small amounts and are used after granulation, making it difficult to apply fertilizers evenly: the appropriate amount of micronutrient fertilizers is generally narrow, and soluble micronutrient fertilizers are often used in close contact. Plants with particles will be poisoned; long-distance plants cannot touch soluble micro-fertilizer particles, and trace elements are less mobile in the soil, so it is almost impossible to absorb the trace elements applied to the soil in the current season; only a few distance Appropriate p...
