Abstract

The invention provides a macro-element water-soluble fertilizer and a preparation method thereof, and belongs to the field of fertilizers. The macro-element water-soluble fertilizer is prepared from the following raw materials in parts by weight: 300-350 parts of ammonium dihydrogen phosphate, 400-450 parts of potassium nitrate, 200-250 parts of urea, 45-55 parts of anhydrous magnesium sulfate and 1-2 parts of anticaking agents. Compared with the prior art, the method provided by the invention can be used for effectively controlling the moisture, heavy metal content and water-insoluble substance content of a product and preventing caking from appearing in a preparation process.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a large-element water-soluble fertilizer and a preparation method thereof. Background technique [0002] Macroelement water-soluble fertilizer has the following advantages. [0003] 1. The raw material is ultra-pure, free of impurities, and low in electrical conductivity, so it can be safely applied to various economic crops such as vegetables, flowers, fruit trees, tea, cotton, tobacco, and lawn; 2. It can fully meet the requirements of agricultural producers for high quality and high stability. Product requirements; 3. Complete water solubility, excellent purity, suitable for all fertilization systems, can be used for bottom application, flushing, drip irrigation, sprinkler irrigation, foliar spraying, and long-term application will not cause soil acidification and compaction; 4. With good compatibility, it can be mixed with most pesticides (except strong alkaline pesticides) to reduce operatin...
