Problems solved by technology

[0003] Although potassium sulfate is a strong acid and strong alkali salt, its dissolution rate in water is very slow. The sulfate radical reacts with calcium ions to form precipitates, which seriously affects its fertilizer efficiency and brings inconvenience to fertilizer application, especially water-soluble fertilizer application.
In order to accelerate its dissolution, the method of shaking (24 hours) and heating is often adopted, which not only increases time cost, labor cost, and energy cost in the process of fertilization, but also is difficult to apply on a large scale

Abstract

The invention relates to an organic nutrient type potassium sulfate dissolution accelerator as well as preparation and application thereof. The organic nutrient type potassium sulfate dissolution accelerator is prepared from an organic acid mixture solution, tyrosine, leucine, threonine, alcohol amine and the like. The organic nutrient potassium sulfate dissolution accelerator has the advantages that the dissolution speed of potassium sulfate can be increased by 6-120 times, in addition, the organic nutrient function on crops is achieved, and the nutrient efficiency of the elements of potassium and sulfur is further improved through the synergistic effect of organic nutrients and inorganic nutrients.

Description

【Technical field】 [0001] The invention belongs to the technical field of fertilizer production. More specifically, the present invention relates to a kind of organic nutrition type potassium sulfate dissolution accelerator, also relate to a kind of preparation method of organic nutrition type potassium sulfate dissolution accelerator, also relate to the purposes of described organic nutrition type potassium sulfate dissolution accelerator. 【Background technique】 [0002] Potassium sulfate is a salt composed of sulfate ions and potassium ions, usually in the form of colorless or white crystals, granules or powder. Potassium sulfate is an important type of potash fertilizer in my country, and it is also an important raw material for the production of compound fertilizers and water-soluble fertilizers. It has the following advantages: 1. It is especially suitable for chlorine-sensitive crops such as tobacco, citrus, grapes, and potatoes; 2. The sulfur-deficient soil area in my...
