Problems solved by technology

[0003] At present, the best way to produce seaweed organic fertilizer is biological enzymatic hydrolysis, followed by physical method, while chemical hydrolysis method is poor
At present, most manufacturers in the world mainly use chemical hydrolysis to produce seaweed fertilizer. The disadvantage of chemical hydrolysis is that strong alkali and high temperature destroy the activity of seaweed endogenous substances. For example, the Chinese invention with publication number CN102515938A discloses a kind of seaweed fertilizer. The preparation method comprises the following steps: 1) removing impurities and foreign matter from seaweed; 2) soaking completely in ethanol for 24 hours; 3) concentrating the leachate under reduced pressure to an extract; 4) freeze-drying the residue part; Mix evenly; 6) spray drying, dry granulation to obtain seaweed fertilizer

Embodiment 1

[0055] like figure 1 Shown, a kind of preparation method of enzymolysis highly active seaweed organic fertilizer comprises:

[0056] (1) Raw material screening

[0057] Sea millet picked in season from September to December is selected, dried and crushed into a powder with a fineness of about 0.1mm; Semen psyllium is also dried and pulverized, and the two substances are combined into sea millet: Semen psyllium = 99:1 The mass ratio is mixed evenly.

[0058] (2) Enzymatic fermentation

[0059] The first stage of fermentation: Weigh 400kg of the mixed sea millet and psyllium raw materials according to the fermentation process regulations, put them in the fermentation tank, add 1600kg of water, stir them evenly, and steam sterilize at 121°C for 30 minutes . After sterilization, when the temperature of the material drops to 38°C, keep the temperature constant, insert the cultured actinomycete liquid seeds according to the aseptic method, the inoculum amount is 40kg, and fermen...

Abstract

The invention belongs to the fields of modern agriculture, new agricultural inputs, new fertilizer and soil conditioner, and relates to a preparation method of enzymatic hydrolysis high activity algae organic fertilizer. The method mainly uses a two-segment hydrolysis approach for complete extraction method of algae endogenous active substances and nutrients; and first actinomycete is used for fermentation, and then Bacillus is used for fermentation, so as to prepare the organic fertilizer containing high content of algae active ingredient. Main technical indexes of the algae organic fertilizer provided by the invention meet the followings: organic matter no less than 95 g / L, alginate no less than 20g / L, and total amount of Cu, Zn, Mo and B no less than 4 g / L. The organic fertilizer can increase crop yield, improve the quality of agricultural products, especially has grater yield increasing effect and economic benefit on economic crops such as cotton, tobacco, mulberry and tea, and horticulture.

Description

technical field [0001] The invention belongs to the field of modern agriculture / new agricultural inputs / new fertilizers and soil conditioners, and relates to a method for preparing an enzymatically hydrolyzed high-activity seaweed organic fertilizer and a product thereof. Background technique [0002] At present, the fertilizer industry in the world is developing from energy-based chemical fertilizers to environment-friendly natural organic fertilizers. Seaweed fertilizer produced from marine algae is a new type of green organic fertilizer emerging in the world today. It is very suitable for modern people's trend of favoring green food and organic food. The market demand has shown a rapid growth trend. [0003] At present, the best way to produce seaweed organic fertilizer is the biological enzymatic method, followed by the physical method, and the chemical hydrolysis method is poor. At present, most manufacturers in the world mainly use chemical hydrolysis to produce seawe...
