[0005] Step 1: Add 1-2 tons of water and 20-50 kg of potassium carbonate into a reactor, then add 80-500 kg of seaweed, heat to 50-65°C, stir and react for 2-4 hours to obtain seaweed liquid;

[0006] Step 2: Filter the seaweed liquid reacted in step 1, collect and cool the filtrate, neutralize the filtrate with 13-17 kg of potassium dihydrogen phosphate, adjust the pH value to 7, and obtain a neutralized seaweed liquid;

[0007] Step 3: Mix the neutralized seaweed liquid, polysaccharide and amino acid in the ratio of 8:1:1 in step 2, prepare the fermentation liquid at a concentration of 30%, add round brown nitrogen-fixing bacteria, Bacillus thuringiensis, Bacillus subtilis and Aspergillus niger, 0.5VV, control the temperature at 30 degrees Celsius, adjust the pH to 6.5 for fermentation, and ferment for a period of 32-48 hours to obtain the fermentation liquid;

[0008] Step 4: Compound the fertility elements in the fermented liquid fermented in step 3.

[0009] Preferably, the seaweed is one or a combination of Sargassum or Ascophyllum nodosum.

[0010] Preferably, the 13-17 kg of potassium dihydrogen phosphate in step 2 can also be replaced by 10-15 kg of 85% phosphoric acid.

[0011] Preferably, the contents of nitrogen, phosphorus and potassium in step 4 reach nitrogen + phosphorus pentoxide + potassium oxide>10 g / L.

[0012] Beneficial effects: The present invention provides a bacterial fertilizer rich in seaweed polypeptides. The main benefits of the bacterial fertilizer rich in seaweed polypeptides include improving soil quality, promoting plant growth, enhancing stress resistance and environmental health. Seaweed polypeptide fertilizers are rich in various nutrients, can promote plant growth and development, enhance plant health, and at the same time improve soil structure, increase soil fertility, and increase yield;

[0013] Seaweed polypeptide fertilizer improves soil quality, increases soil aeration and water retention, promotes the growth of soil microorganisms, and improves soil fertility and disease resistance by providing rich organic matter and trace elements. It also contains a variety of beneficial microorganisms that can repair soil, improve soil structure, neutralize soil pH, passivate soil heavy metals, and degrade pesticide residues, thereby regulating the growth balance of crops, promoting the development of root systems, and increasing the number of crop capillary roots;

[0014] Seaweed polypeptide fertilizer can improve seed germination rate, promote root development, increase crop nutrient absorption, activate enzymes related to growth and development, promote chloroplast absorption and conversion of light energy, and accelerate carbon and nitrogen metabolism. It can also maintain the stability of crop chlorophyll, improve the formation and accumulation of photosynthetic products, improve yellowing, and promote growth. In addition, seaweed polypeptide fertilizer can also advance the time to market, improve crop resistance, and prevent or reduce the occurrence of crop diseases;

[0015] Seaweed polypeptide fertilizer is a natural organic fertilizer that does not contain chemical ingredients and heavy metals and is harmless to the environment and human health. It can reduce the use of chemical fertilizers and pesticides, reduce soil and water pollution, and protect the ecological environment and human health. DETAILED DESCRIPTION
