Embodiment 1

[0038] A production method of seaweed biocomposite organic liquid fertilizer, said method comprising the following steps:

[0039] 1) Remove silt or other impurities in fresh kelp;

[0040]2) Crushing and grinding the fresh kelp and forcing it through a small-mesh sieve to break the kelp cells, and use a suction machine to put it into a fermenter that has been sterilized by high temperature;

[0041] 3) Add pure fresh water 0.3 times the mass of fresh kelp;

[0042] 4) Adjust the pH value to 6.8, add protease and cellulase accounting for 1.0% of the mass of fresh kelp, and add Bacillus subtilis and Bacillus licheniformis accounting for 0.6% of the mass of fresh kelp. about hours;

[0043] 5) Heat and keep warm after stirring evenly. The temperature is controlled at 60°C and the pressure is controlled at 0.01Mpa. Add sterile air once every 4 hours. The amount of sterile air ventilation is 0.4 times the tank volume. Stir once every 2 hours. 90h;

[0044] 6) After filtering t...

Abstract

The present invention relates to a production method for a seaweed bio-composite organic liquid fertilizer. The method comprises the following steps: carrying out crushing grinding on fresh kelps; adding the crushed kelp slurry to a fermentation tank, and adding water; adjusting the pH value to 6.8-8.8, adding a composite enzyme and a microbial fermentation bacteria agent, uniformly stirring, and heating to a temperature of 25-60 DEG C, wherein the thermal insulation fermentation time is at least 85 hours; and filtering, and adding an acid production bacterial agent to obtain the seaweed bio-composite organic liquid fertilizer. According to the present invention, the water used in the method adopting the fresh kelps as the raw material to produce the product is saved by 90% compared with the method adopting the dried kelp raw material to produce the product; the energy is saved by 40% by adopting solar heating and thermal insulation fermentation production, the production cost can be reduced by 25%, and characteristics of energy saving, water saving, low carbon and environmental protection are provided; the seaweed bio-composite organic liquid fertilizer of the present invention has effects of combination of organic fertilizer, inorganic fertilizer, microbial fertilizer, and medium and trace element fertilizer, rapid acting, long lasting time, synergy, fertilizer retention, water retention, cold resistance, insect repelling, disease resistance, soil improving, and the like.

Description

technical field [0001] The invention relates to a production method of seaweed bio-composite organic liquid fertilizer, in particular to a method for decomposing and extracting seaweed liquid from fresh kelp to prepare high-efficiency and long-acting seaweed bio-compound organic liquid fertilizer by using complete biological enzymolysis and fermentation technology. Background technique [0002] Seaweed fertilizer is made from large fast-growing brown algae that grow in the ocean. Through chemical, physical or biological methods, the active ingredients in seaweed are extracted to make fertilizer and given to plants as nutrients. It can promote plant growth , increase yield and improve the quality of agricultural products. Seaweed fertilizer is a natural organic fertilizer, and its fertilizer efficiency depends on the main active substances such as cytokinin, auxin, gibberellin, abscisic acid, ethylene, betaine, and polyamine contained in seaweed fertilizer. In addition to a ...
