Water-soluble fertilizer containing humic acid and production method thereof

Abstract

The invention belongs to the technical field of agricultural fertilizers, and particularly relates to a water-soluble fertilizer containing humic acid and a production method of the water-soluble fertilizer. The water-soluble fertilizer is prepared from the following components in parts by weight: 10 parts of biogas slurry, 8 parts of potato residue homogeneous liquid, 5 parts of vegetable residue fermentation liquid, 6 parts of mushroom polypeptide liquid, 2 parts of microbial polysaccharide, 3 parts of potassium fulvic acid and 12 parts of urea. 22 parts of potassium dihydrogen phosphate and 1 part of vitamin B complex. The water-soluble fertilizer is rich in biogas slurry, humic acid and macroelements such as nitrogen, phosphorus and potassium, balanced in nutrition, capable of improving soil properties, providing comprehensive nutrient elements for crop growth, promoting crop growth and effectively improving the crop yield and quality, capable of being widely used for cultivation of crops such as sweet sorghum, ryegrass and highland barley, capable of improving the yield by 10-25% and good in application and popularization prospect.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizers, and in particular relates to a water-soluble fertilizer containing humic acid and a production method thereof. Background technique [0002] Soil is the loose soil surface for crop growth, and fertility is the basic characteristic of soil. There are many basic soil properties that affect fertility, including: the thickness of the plow layer, the texture and structure of the plow layer, the content of organic matter in the soil, the content of nutrients such as nitrogen, phosphorus, and potassium in the soil, and the pH of the soil. At present, in the domestic cultivated soil, the fertility level is low, the soil physical and chemical properties are poor, and the saline-alkali compaction is serious. The low-yielding soil with low crop yield accounts for about 30%. In particular, the fertilization of crops is dominated by chemical fertilizers. Due to long-term excessive or unreaso...

Problems solved by technology

Comparing patent 1, a production method of humic acid water-soluble fertilizer (application number CN201811512273.9) in its formula, calcium, ferrous sulfate, manganese sulfate, etc. are easily precipitated during the mixing process, resulting in agglomeration and reduced fertilizer efficiency

Comparing patent 2, a water-soluble fertilizer containing high concentration of humic acid and its preparation method (patent number: 201310357167.9), its formula contains potassium acetate and borax, heated and stirred to obtain a mixed solution that is easy to react after cooling, resulting in the loss of active ingredients
