Abstract
The invention provides a compound fertilizer and a preparation method thereof. The preparation method comprises the following steps: soaking sepiolite powder and stalactite in an acetic acid solution;mixing the sepiolite powder and the stalactite with the sodium carboxymethyl cellulose, and after high-temperature calcination, decomposing and volatilizing the sodium carboxymethyl cellulose at hightemperature so that the sepiolite powder and the stalactite contain a large number of pores, and absorbing effective components in the compound fertilizer in the pores and slowly releaing so that theeffective period of the compound fertilizer is prolonged. According to the preparation method, part of the raw materials are placed in a first barrel body to react under the high-pressure condition,the remaining raw materials are placed in a second barrel body to react, then the raw materials in the first barrel body and the raw materials in the second barrel body are continuously mixed to react, and high pressure is maintained, so that the reaction is sufficient, and the content of nitrogen, phosphorus and potassium in the compound fertilizer is further increased; according to the preparation method disclosed by the invention, the nanogold catalyst layer is loaded on the inner wall of the second barrel body, and the reaction can be more sufficient by arranging the nanogold catalyst layer, so that the content of nitrogen, phosphorus and potassium in the compound fertilizer is increased.
Description
technical field [0001] The invention relates to the technical field of fertilizers, in particular to a compound fertilizer and a preparation method thereof. Background technique [0002] In recent decades, there are still some disadvantages in the production and utilization of chemical fertilizers in my country, which restrict the sustainable development of agriculture to a certain extent. Due to the lack of scientific and rational use of chemical fertilizers, some people apply a single variety of chemical fertilizers or one-sidedly believe that more fertilizers are needed to increase production, resulting in an increase in the amount of fertilization every year. my country's cultivated land area accounts for only 7% of the world's total, but its chemical fertilizer consumption accounts for 100% of the world's total. More than 1 / 3 of the world's consumption, but the output has not achieved the expected effect, and even has side effects, which not only causes a serious waste o...
