Microbial bacterial manure with ascophyllum nodosum as matrix

Abstract

The invention discloses microbial bacterial manure with ascophyllum nodosum as a matrix. The microbial biological manure is prepared by the steps: activating and culturing microbial flora to obtain aseed solution, performing amplification culture on the seed solution to obtain a microbial bacterial agent, then mixing and feeding raw materials into a stirring tank according to a weight ratio of 30% to 70% of ascophyllum nodosum dreg, 1% to 20% of soya bean cake and 1% to 5% of microbial bacterial agent, keeping a water content as 40 to 60%, bagging after the materials are evenly stirred, sealing an opening, obtaining finished product stacking, continuing fermentation and naturally degrading for 7 to 15d to obtain the microbial bacterial manure. The microbial bacterial manure not only can improve soil and improve soil breathability and agglomeration capacity, but also can stimulate plant to generate growth regulating matter (polyamine) and formation of antibiotic (plant antitoxin) afterbeing absorbed by plants.

Description

technical field [0001] The invention relates to the technical field of green biological fertilizers, in particular to a microbial fertilizer based on Ascophyllum nodosum. Background technique [0002] Ascophyllum nodosum belongs to the Phaeophyta and is mainly grown on the coast near the Arctic Ocean. Seaweed fertilizer is made of large fast-growing brown algae that grows in the ocean as raw material. Through chemical, physical or biological methods, the active ingredients in seaweed are extracted to make fertilizer and given to plants as nutrients. Seaweed fertilizer contains various macroelements, trace elements, seaweed polysaccharides, highly unsaturated fatty acids and various natural plant growth regulators, such as auxins, gibberellins, cytokinins, and polyphenolic compounds. and antibiotics etc. These substances have high biological activity, can stimulate the production of non-specific active factors in plants and regulate the balance of endogenous hormones, can p...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the shortcoming that Ascophyllum nodosum can not exert the maximum effect when used alone, adding microbial inoculum can improve the fertilizer utilization rate of Ascophyllum nodosum residue, but there has not been a unified optimal effect and selection of the best inoculum. The present invention mainly solves the problem of The coordination relationship between microbial agents and Ascophyllum nodosum, the optimal microbial fertilizer for Ascophyllum nodosum
