Embodiment Construction

[0021] The following examples illustrate the present invention in more detail, but are not limited to the following examples as long as it falls within the scope of the present invention.

[0022] A humic acid-containing water-soluble fertilizer produced by using yeast thick slurry waste liquid. The yeast thick slurry contains humic acid, nitrogen, and potassium. After the yeast thick slurry is activated, it is used with inorganic adsorbent raw materials: water-soluble It is made by dissolving and mixing neutral urea, potassium dihydrogen phosphate and potassium sulfate.

[0023] Its specific formula ratio and steps are:

[0024] The prepared yeast concentrate containing humic acid and the raw materials of inorganic adsorbent: water-soluble urea, potassium dihydrogen phosphate, potassium sulfate, and mineral humic acid are prepared in a ratio of 60:10:20:10, and are heated and stirred evenly. become.

Abstract

The invention relates to a humic acid-contained water-soluble fertilizer produced by using a waste dense yeast slurry. The fertilizer is obtained through a preparation method comprising the following steps: 1, activating the dense yeast slurry containing humic acid, N and K; and 2, dissolving and mixing an organic adsorption substance raw material in the activated dense yeast slurry, wherein the organic adsorption substance raw material is obtained by uniformly stirring water-soluble urea, potassium dihydrogen phosphate, potassium sulfate and mineral humic acid according to a ratio of 60:10:20:10 with heating. The fertilizer which belongs to the waste utilization allows environment to be maintained and the production cost to be reduced.

Description

technical field [0001] The invention relates to the field of humic acid-containing water-soluble fertilizers, in particular to a humic-acid-containing water-soluble fertilizer produced by using yeast thick slurry waste liquid. Background technique [0002] In my country, due to the long-term application of large amounts of chemical fertilizers in the farmland, the soil is compacted, the soil fertility is weakened, the quality of agricultural products is reduced, and the taste is not good. At the same time, harmful residues are absorbed by crops and affect human health after eating. must do. Especially with the popularization of facility agriculture and the arrival of the era of low-carbon economy, the demand for water-soluble fertilizers in high-efficiency agriculture will increase significantly. [0003] The humic acid-containing water-soluble fertilizer is the product that meets this requirement. [0004] Humic acid-containing water-soluble fertilizer is a kind of quick-a...
