Problems solved by technology

The application of organic fertilizer can improve soil organic matter, but the inventors found that the use of organic fertilizer per unit area is large and the degree of mechanization is quite low, so it can only rely on manual operation; and artificial fertilization is labor-intensive, labor-intensive, and the uniformity of spreading results in poor fertilizer utilization. and use efficiency are very low, and the application cost is high
Organic fertilizers contain carbon nutrition, but water solubility is mostly less than 10%, generally around 2%, and it is difficult to be directly absorbed by roots

Abstract

The invention provides an organic water-soluble fertilizer containing a water-soluble carbon compound as well as a preparation method and application thereof. The organic water-soluble fertilizer comprises a tobacco extracting solution, ammonium polyphosphate, potassium polyphosphate and urea ammonium nitrate; wherein the tobacco leaching solution is an aqueous solution obtained by carrying out high-temperature acidolysis, alkaline hydrolysis and low-pressure concentration on tobacco dry substances. The micromolecular water-soluble carbon compound used in the method is derived from a tobacco leaching solution, phosphorus and potassium are mainly derived from ammonium polyphosphate and potassium polyphosphate, and nitrogen is mainly derived from a urea ammonium nitrate solution. The fertilizer is high in cost performance, simple in production process and remarkable in yield increase and quality improvement effects, and has a good practical application value.

Description

technical field [0001] The invention belongs to the technical field of water-soluble fertilizers, and in particular relates to an organic water-soluble fertilizer containing water-soluble carbon compounds and a preparation method and application thereof. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] Organic carbon nutrition refers to organic carbon compounds with high water solubility and easy absorption by plants. There are both nitrogen-containing organic carbon nutrition and nitrogen-free carbon nutrition. Various carbon frames, including chains and rings, are the basic substances for plants to synthesize sugars, proteins, amino acids, enzymes, hormones, and signal ...
