Composite microbial seaweed organic liquid fertilizer and preparation method thereof

Abstract

The invention relates to a preparation method for a composite microbial seaweed organic liquid fertilizer, which comprises the following steps: (1) ingredient treatment: adding 0.1-0.6 part by weight of complex enzyme and 0.1-0.4 part by weight of microbial leaven to 100 parts by weight of seaweed-crushed liquor of which the water content is 70-90 percent, and evenly mixing; (2) aerobic fermentation: filling an ingredient obtained in the step (1) into a fermentation tank, and carrying out the aerobic fermentation for 5-8 days at the temperature of 40-60 DEG C under the condition that pH is 5-7 to obtain fermentation liquor; (3) filtering: filtering the fermentation liquor obtained in the step (2) to obtain filter liquor; and (4) compounding: adding functional fungicides to the filter liquor obtained in the step (3), wherein the functional fungicides comprise nitrogen-fixing bacteria, phosphate-solubilizing bacteria and potassium bacteria; or / and adding bacillus subtilis and Bacillus licheniformis to the filter liquor obtained in the step (3); and carrying out blending on nitrogen phosphorus potassium (NPK) so as to enable the content of the NPK to reach the goal that N+P2O5+K2O isnot less than 4 percent.

Description

technical field [0001] The invention belongs to the field of organic fertilizer and organic fertilizer manufacture, and in particular relates to a compound microbial seaweed organic liquid fertilizer and a preparation method thereof. Background technique [0002] Seaweeds such as kelp, giant algae, Ascophyllum nodosum, sea sac, and kelp are rich in various inorganic, organic, and biologically active substances that are useful for crop growth, and are very good agricultural fertilizers. The application of seaweed in agriculture has a long history. Many coastal countries in the world have collected seaweed to make compost long ago, that is, the brown algae washed to the coast by wind and waves will be piled up or buried in soil pits to make them compost. Naturally fermented to make seaweed fertilizer, the effect of increasing agricultural production is obvious. [0003] Under the conditions of modern industrialization, the production methods of seaweed fertilizer can generall...

Problems solved by technology

However, the production of seaweed fertilizer by biological fermentation also has many disadvantages: for example, it is difficult to ferment macromolecular substances such as seaweed fiber, calcium alginate, fucoidan, protein, pectin, etc. , leading to too long production cycle; the degree of fermentation is not high, and the utilization rate of seaweed is not high, causing problems such as environmental pollution and waste of resources

Moreover, the process of producing seaweed fertilizer by biological fermentation lacks in-depth systematic research on its process and application mechanism. At present, it is limited to the laboratory research and exploration stage at home and abroad, and there is no mature and feasible preparation process for large-scale production.

[0005] Due to the limitations of their respective production processes, the current various seaweed fertilizers have low effective nutrient content and lack of active substances, resulting in low fertility and poor effect
