Abstract

The invention belongs to the technical field of chemical engineering and particularly discloses a method for utilizing gibberellins raffinate to prepare a high-activity water flush fertilizer. The method for utilizing the gibberellins raffinate to prepare the high-activity water flush fertilizer comprises the steps of 1 preparing a concentrated solution of the gibberellins raffinate, 2 regulating the pH value of the gibberellins raffinate, 3 preparing a microelement chelated fertilizer, 4 preparing a macroelement nutrient solution and 5 compounding the water flush fertilizer. By means of the method, waste liquid produced in the gibberellins producing process is subjected to resource utilization, discharged sewage is prevented from polluting the environment, and more types of fertilizer resources are provided for agricultural development. The target product produced by means of the method can meet the demands of different plants in different growing periods and has the remarkable yield-increasing and quality-improving effects on vegetables, melons and fruits.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a method for preparing high-activity fertilization by using gibberellin raffinate. Background technique [0002] Gibberellin is a plant growth regulator, commonly known as "Nine Twenty". After the gibberellin fermentation liquid is extracted from the gibberellin, a waste liquid will be produced, which is the gibberellin raffinate. Every 5t of gibberellin Fermentation broth produces about 2.2t of raffinate waste liquid, which is an acidic, yellow-brown substance, mainly containing 21.8% of amino acids, 43.58% of sugar, 33.57% of protein and about 1% of trace elements on a dry basis And trace amounts of gibberellin 0.2%-0.3%. At present, in the treatment of raffinate in our country, it is still treated as sewage, and scientific and reasonable resource utilization has not been carried out. This not only caused a great waste of nutrients in the gibberellin raf...
