Problems solved by technology

The transportation of liquid water-soluble fertilizer is inconvenient, and the use of powder water-soluble fertilizer is inconvenient. Moreover, the existing water-soluble fertilizer only contains some simple nitrogen, phosphorus and potassium elements, and lacks other medium and trace elements needed by plants. The absorption of these two types of water-soluble fertilizers by plants rate is also lower
In addition, the use of existing water-soluble fertilizers is also limited, and it is limited for arid and humid areas. The price is relatively expensive, which is not easy for users to accept, and the market application is relatively limited.

Abstract

The invention relates to a granular water-soluble fertilizer and a preparation method thereof, and belongs to the technical field of fertilizer production. The granular water-soluble fertilizer is prepared from 83%-86% of ammonium sulfate, 4.8%-5.2% of potassium sulfate, 2%-5% of magnesium sulfate, 2.4%-3% of potassium fulvic acid, 0.2%-1.2% of ethylenediamine tetraacetic acid and 2%-3.5% of molasses fermentation liquor. The fertilizer is a water-soluble granular fertilizer composed of multiple elements, the elements not only contain nitrogen, phosphorus and potassium which can meet the basic requirements of economic crops, but also contain multiple medium-trace elements needed by the crops, the fertilizer is suitable for the economic crops such as fruits and vegetables, leafy vegetables and rhizomes, and the fruit swelling, coloring, rooting and root strengthening effects are significant. In addition, the granular water-soluble fertilizer is high in solution rate, capable of being easily absorbed by plants, higher in absorptivity, capable of achieving integration of water and the fertilizer, convenient to transport and use, lower in cost, capable of being accepted by users more easily and wider in market application.

Description

technical field [0001] The invention relates to a granular water-soluble fertilizer and a preparation method thereof, belonging to the technical field of fertilizer production. Background technique [0002] At present, the demand for new fertilizers in my country is increasing, and the requirements are constantly improving. Traditional water-soluble fertilizers are basically divided into two categories: liquid and powder. The transportation of liquid water-soluble fertilizer is inconvenient, and the use of powder water-soluble fertilizer is inconvenient. Moreover, the existing water-soluble fertilizer only contains some simple nitrogen, phosphorus and potassium elements, and lacks other medium and trace elements needed by plants. The absorption of these two types of water-soluble fertilizers by plants rate is also lower. In addition, the use of existing water-soluble fertilizers is also limited, and it is limited to arid and humid areas. The price is relatively expensive, ...
