Organic-inorganic liquid water-soluble fertilizer

Abstract

The invention discloses an organic-inorganic liquid water-soluble fertilizer prepared from biogas slurry, monopotassium phosphate, ammonium polyphosphate, calcium ammonium nitrate, zinc sulfate, ammonium nitrate and 3,4-dimethylpyrazole phosphate.According to the water-soluble fertilizer, the better effect is achieved through the synergistic promotion effect of organic nutrients and inorganic nutrients, and the utilization rate of zinc ions and calcium ions can be increased through the chelation of free amino acid in the biogas slurry and humic acid, so that the zinc ions and the calcium ions are free from being immobilized by soil.After the prepared water-soluble fertilizer is adopted, an existing mode of organic fertilizer bottom application, compound fertilizer bottom application and water-soluble fertilizer top dressing can be completely replaced, and the effects in the aspects of saving labor, improving the disease resistance of crops and improving the product quality and the like are significant.

Description

technical field

[0001] The invention relates to a water-soluble fertilizer, in particular to an organic-inorganic liquid water-soluble fertilizer. Background technique

[0002] Water-soluble fertilizers have been rapidly popularized in my country, especially in areas with high added value of agricultural products such as vegetables, fruits, and traditional Chinese medicinal materials. Water-soluble fertilizers have significant effects in saving labor and improving water and fertilizer utilization. However, problems such as decline of soil organic matter and acidification caused by excessive application of chemical fertilizers are common in water-soluble fertilizer application areas. bring about an increase in labor costs. Biogas slurry is a by-product of biogas, which contains organic matter, humic acid, free amino acids and a small amount of effective components such as nitrogen, phosphorus and potassium, and is an excellent weakly alkaline liquid fertilizer. However, if ...
