Method for producing anti-freeze swelling coloring biological fertilizer by using fulvic acid potassium

Abstract

The invention discloses a method for producing an anti-freeze swelling coloring biological fertilizer by using fulvic acid potassium. The method comprises the following steps of: preparing a biological fermentation bacteria agent, selecting materials and mixing. The method has the advantages that the anti-freeze swelling coloring biological fertilizer is good in anti-frost property, significant in swelling coloring effect, strong in fertilizer efficiency and lasting in effect; soil hardening is not caused by long-time application; the preparation method is simple; the reaction speed and activity of a soil probiotic group can be fully improved; the activity cycle of a crop is changed; the absorption rate of nitrogen, phosphorus and potassium in soil and the utilization rate of a later additional fertilizer are improved; the cold resistance, the drought resistance, the pest resistance, remission of phytotoxicity and the like are achieved, so that internal energy of a crop body is improved; the effects of improving the quality, and increasing production and income are achieved.

Description

technical field [0001] The invention relates to a production method of a biological fertilizer, in particular to a method for producing an antifreeze expanded fruit colored biological fertilizer by using potassium fulvic acid, belonging to the field of biological fertilizer production. Background technique [0002] Potassium fulvic acid (BSFA) is the application of modern biotechnology, using plant slag as raw material, through biological fermentation, successfully produced a coal-like fulvic acid substance---high activity BSFA type biochemical potassium fulvic acid, and became a coal-forming fulvic acid The best substitute for acid. Studies have confirmed that the physiological functions of potassium fulvic acid mainly include: scientific combination of new nutrient chains, comprehensively balancing plant needs; unknown growth-promoting factors with high biological activity functions; strong complexing ability, improving the absorption and operation of plant trace elements;...

Problems solved by technology

[0003] At present, most of the commonly used potassium fertilizers are chemical fertilizers. Although they have a certain growth-promoting effect on crops, their fertilizer properties are single and unsuitable for saline-alkali land and some crops. Long-term application will easily cause soil compaction, deterioration of the planting environment, and ultimately affect crops. income

Moreover, its antifreeze performance is poor, and the coloring effect on pistachios is not obvious
