Abstract

The invention relates to water-soluble fertilizer and a preparation method thereof. The water-soluble fertilizer comprises the following raw materials in parts by weight: 40 to 55 parts of monoammonium phosphate, 10 to 15 parts of ammonium sulfate, 5 to 10 parts of potassium sulphate, 20 to 25 parts of monopotassium phosphate, 0.35 to 1 part of a copper chelating agent, 0.35 to 1 part of a zinc chelating agent, 0.4 to 1.1 parts of an iron chelating agent, and 0.35 to 0.9 part of borax. The preparation method comprises the following steps: putting a nitrogen source, a phosphorus source and a potassium source into a dissolving tank, adding water to prepare paste, then putting the paste into another dissolving tank, adding microelements to prepare paste again, putting the produced paste intogranulation equipment to prepare semi-finished product fertilizer granules, performing drying, screening and cooling processes on the semi-finished product fertilizer granules, so as to obtain the finished product, namely the water-soluble fertilizer granules. The water-soluble fertilizer is low in production cost, high in water solubility, and complete in nutrient element coverage, realizes comprehensive utilization of waste, and eliminates environmental pollution.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizer production, and in particular relates to a water-soluble fertilizer and a preparation method thereof. Background technique [0002] Water-soluble fertilizer is a multi-component compound fertilizer that can be completely dissolved in water. It can be quickly dissolved in water and is more easily absorbed by crops, and its absorption and utilization rate is relatively high. At the same time, it can be applied to facility agriculture such as sprinkler irrigation to achieve The integration of water and fertilizer achieves the effects of saving water, fertilizer, labor and increasing production. In recent years, it has received extensive attention. [0003] At present, the varieties of ammonium phosphate fertilizers can be divided into three categories. ① Ammonium orthophosphate is the most productive type, and the main varieties are diammonium phosphate, monoammonium phosphate and a...
