Organic/inorganic liquid compound fertilizer and preparation method thereof

Abstract

The invention relates to an organic / inorganic liquid compound fertilizer and a preparation method thereof. The organic / inorganic liquid compound fertilizer consists of the following raw materials in parts by weight: 10-60 parts of potassium fulvate / or humate, 60-90 parts of citric acid waste liquid with mass concentration of 80-90%, 20-30 parts of inorganic phosphorus fertilizer, 10-15 parts of inorganic potash fertilizer, 30-45 parts of inorganic nitrogenous fertilizer, 5.5-8.25 parts of trace element fertilizer, 6-8 parts of guar gum, 3-5 parts of non-ionic polyacrylamide and 5-8 parts of potassium polyacrylate. According to the organic / inorganic liquid compound fertilizer and the preparation method thereof, the organic content of the final product is increased by use of the characteristic that the citric acid waste liquid contains a large quantity of organic residues to form an organic / inorganic liquid compound fertilizer, the supply of nutrients for the rice with drip irrigation under a plastic film is guaranteed while the organic content of the cultivated soil is gradually increased; the soil is further improved while high quality and high yield of the rice with drip irrigation under the plastic film are obtained; moreover, by adopting certain amount of guar gum, non-ionic polyacrylamide and potassium polyacrylate, the utilization rate of the phosphorus fertilizer is effectively increased.

Description

technical field [0001] The invention relates to an organic-inorganic liquid compound fertilizer and a preparation method thereof, belonging to the technical field of liquid fertilizers. Background technique [0002] The use of nitrogen fertilizer in crop planting has played a great role in agricultural production. After a period of time, it was found that the soil was deficient in phosphorus, so a large amount of superphosphate and diammonium phosphate began to be used, and then potassium deficiency appeared in the soil, and the fertilizer was added. Potassium fertilizer has caused agricultural planting to rely too much on chemical fertilizers, ignoring the supplement of soil organic matter, causing many difficult problems in agricultural production, mainly due to high salinization of soil. [0003] There is a common phenomenon of "three heavy and three light" fertilization by farmers, that is, heavy chemical fertilizers, light organic fertilizers, heavy nitrogen and phospho...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a kind of organic-inorganic liquid compound fertilizer and its preparation method, to overcome the problem that the drip irrigation fertilizer using sulfuric acid as raw material in the prior art is corrosive to the drip irrigation equipment, and the existing under-film drip irrigation cultivation used The proportion setting of each effective component of drip irrigation fertilizer is unreasonable, the transmission speed is slow, and the utilization rate is low.
