Embodiment 1

[0029] (1) Wash and shred the dried seaweed into the reaction kettle for soaking. The amount of dried seaweed added is 10% of the water. Soak for 2 hours at a temperature of 25°C. The supernatant after soaking is passed through the ion exchange resin Filter to remove salt and heavy metals, and obtain solution A.

[0030] (2) Return solution A to the reaction kettle, add potassium citrate according to the weight ratio of dry seaweed: 0.6:100, soften and digest the seaweed at 25°C for 3 hours, after treatment, it will turn emerald green and dry A viscous liquid with a delicate smell was centrifuged to obtain seaweed slag and solution B.

[0031] (3) Add water to the seaweed residue to make the water content reach 40%, adjust the pH to 5.5, add a mixed strain of lactic acid bacteria and yeast with a weight ratio of 20:80, add molasses, yeast extract, and potassium dihydrogen phosphate , zinc sulfate heptahydrate, and ammonium bicarbonate mixed in a weight ratio of 100:7:2:2:2. ...

Embodiment 2

[0035] (1) Wash and shred the dried seaweed into the reaction kettle for soaking. The amount of dried seaweed added is 10% of the water. Soak for 4 hours at a temperature of 25°C. The supernatant after soaking is passed through the ion exchange resin. Filter to remove salt and heavy metals, and obtain solution A.

[0036] (2) Return solution A to the reaction kettle, add potassium oxalate in a weight ratio of 0.4:100 to dry seaweed, soften and digest the seaweed at 20°C for 4 hours, and get emerald green with a delicate fragrance after treatment Odor viscous liquid, seaweed slag and solution B were obtained by centrifugation.

[0037] (3) Add water to the seaweed residue to make the water content reach 45%, adjust the pH to 6.5, add the mixed strain of lactic acid bacteria and yeast according to the weight ratio of 30:70, and then add molasses, yeast paste, and dihydrogen phosphate A culture medium prepared by mixing potassium, zinc sulfate heptahydrate, and ammonium bicarbon...

Embodiment 3

[0041] (1) Wash and shred the dried seaweed into the reaction kettle for soaking. The amount of dried seaweed added is 40% of the water. Soak for 4 days at a temperature of 5°C. The supernatant after soaking is ion-exchanged Filter the resin to remove salt and heavy metals, and obtain solution A.

[0042] (2) Return solution A to the reaction kettle, add potassium pyrophosphate in a weight ratio of 2:100 to dry seaweed, soften and digest the seaweed at 40°C for 2 hours, and the treated clear liquid is emerald green It is a viscous liquid that is green and emits a delicate smell, and is centrifuged to obtain seaweed residue and solution B.

[0043] (3) Seaweed residue is supplemented with water to make the water content reach 40%, adjust the pH to 8.5, add a mixed strain of lactic acid bacteria and yeast with a weight ratio of 40:60, and then add molasses, yeast extract, potassium dihydrogen phosphate, The culture medium prepared by mixing zinc sulfate heptahydrate and ammoniu...

Abstract

The invention relates to a production method of a microbial fermented seaweed fertilizer. The production method comprises the following steps: soaking dried seaweed, taking the liquid supernatant and filtering by use of an ion exchange resin, thereby obtaining a solution A; returning the solution A to a reaction kettle, adding one or two of potassium citrate, potassium oxalate, potassium pyrophosphate and the like in a certain weight ratio for softening and digesting the seaweed at a certain temperature, and performing centrifugal separation on the clear liquid obtained after processing to obtain the filtrate, namely a solution B; supplementing water to the centrifuged seaweed residue and regulating the Ph, next, adding microorganisms and a culture medium, fermenting at a certain temperature, and performing centrifugal separation after fermentation to obtain a solution C after centrifuging; mixing the solution B and the solution C and then mixing with nitrogen fertilizer, phosphatic fertilizer, potash fertilizer, chelate medium trace elements and the like in a certain weight ratio to obtain the microbial fermented seaweed fertilizer. The microbial fermented seaweed fertilizer produced by the production method is capable of improving the growing environment of crop root systems and solving the problem of soil hardening so that the soil is loose, good in moisture and fertility preservation property and excellent in air permeability; as a result, crops can grow healthily in a good environment.

Description

technical field [0001] The invention relates to a method for producing seaweed fertilizer fermented by microorganisms. Background technique [0002] In the 21st century, the Party Central Committee and the State Council put forward the goal of "gradually building my country into a powerful marine economy". In February 2012, the Ministry of Agriculture issued the "Opinions on Promoting the Development of Water-saving Agriculture", clearly proposing "vigorously develop the integration of water and fertilizer". In March 2013, the Ministry of Agriculture issued the "Technical Guidance Opinions on Water and Fertilizer Integration", which takes water and fertilizer integration as the main technology to build an efficient and sustainable modern agricultural system, so as to alleviate the situation of more people and less land in China. On March 18, 2014, the Ministry of Environmental Protection passed the Action Plan for Soil Pollution Prevention and Control. The "Plan" proposes ...
