Embodiment 1

[0024] Select Schizochytrium algae dregs and Paenibacillus polymyxa as raw materials for preparation, and culture Paenibacillus polymyxa in a fermenter until the fermentation broth reaches 10 8 -10 10 cfu / mL. The inorganic impurities in the Schizochytrium algae residue are removed, spread out to dry, and then sent to the pulverizer by the conveyor belt for crushing.

[0025] According to the ratio of adding 1 ton of Schizochytrium algae residue to 10kg of Paenibacillus polymyxa, the two raw materials were weighed and stored separately. After confirming that the equipment was operating normally, the materials were fed into the mixer, and the pH of the mixed raw materials was adjusted to about 7 during the process. After mixing, the principle of discharging is to mix evenly and without variegation.

[0026] Put the uniformly mixed raw materials into the fermentation tank at an ambient temperature of about 25°C, adjust the C / N ratio of the mixed raw materials to 30:1, the moist...

Embodiment 2

[0030] Select Schizochytrium algae dregs and Paenibacillus polymyxa as raw materials for preparation, and culture Paenibacillus polymyxa in a fermenter until the fermentation broth reaches 10 8 -10 10 cfu / mL. The inorganic impurities in the Schizochytrium algae residue are removed, spread out to dry, and then sent to the pulverizer by the conveyor belt for crushing.

[0031] According to the ratio of adding 1 ton of Schizochytrium algae residue to 15kg of Paenibacillus polymyxa, the two raw materials were weighed and stored separately. After confirming that the equipment was operating normally, the materials were fed into the mixer, and the pH of the mixed raw materials was adjusted to about 7 during the process. After mixing, the principle of discharging is to mix evenly and without variegation.

[0032] Put the uniformly mixed raw materials into the fermentation tank at an ambient temperature of about 25°C, adjust the C / N ratio of the mixed raw materials to 25:1, the moist...

Embodiment 3

[0036] Select Schizochytrium algae dregs and Paecilomyces lilacinus as raw materials for preparation, and culture Paecilomyces lilacinus in a fermenter until the fermentation broth reaches 10 8 -10 10 cfu / mL. The inorganic impurities in the Schizochytrium algae residue are removed, spread out to dry, and then sent to the pulverizer by the conveyor belt for crushing.

[0037] According to the ratio of adding 1 ton of Schizochytrium algae residue to 15kg of Paecilomyces lilacinus, the two raw materials were weighed and stored separately. After confirming that the equipment was operating normally, the materials were fed into the mixer, and the pH of the mixed raw materials was adjusted to about 7 during the process. After mixing, the principle of discharging is to mix evenly and without variegation.

Abstract

The invention discloses a preparation method of seaweed biological fertilizer. The preparation method comprises the following steps: taking schizochytrium limacinum dregs and a functional bacterium strain as preparation raw materials, and implementing liquid culture of the functional bacterium strain in a fermentation tank until a fermentation broth contains 108-1010cfu / ml of bacteria for later use; inoculating the schizochytrium limacinum dregs to the cultivated functional bacterium strain, and implementing aerobic fermentation to obtain a fermentation product; sequentially pelletizing, drying, cooling, sieving and packaging the fermentation product to obtain the finished seaweed biological fertilizer. Organic matter content, the number of effective live bacteria and the like in the produced bio-organic fertilizer exceed national standard (NY / 884-2012) of the bio-organic fertilizer, and water content, pH value, roundworm ova death rate and the number of fecal coliforms are consistent with the national standard (NY / 884-2012). Moreover, the preparation method disclosed by the invention is low in investment, low in energy consumption, rapid to become effective and light in pollution; the preparation method can be used for creating social and economic values, and realizing resource utilization of waste in enterprises.

Description

technical field [0001] The invention relates to a method for making fertilizer, in particular to a method for making seaweed biological fertilizer. Background technique [0002] In recent years, due to the large and unreasonable application of chemical fertilizers and chemical pesticides, it not only consumes a large amount of non-renewable resources, but also destroys the soil structure, pollutes the quality of agricultural products and the environment, and affects human health and survival. The annual use of chemical fertilizers in my country is more than 40 million tons. Long-term large-scale use of chemical fertilizers and improper use methods will damage the ecological environment of farmland, soil physical and chemical properties, and soil microbial flora to varying degrees. The adverse consequences caused by excessive and single application of chemical fertilizers have aroused widespread concern from all walks of life. As a new type of fertilizer, the development of ...
