Preparation method of seaweed fertilizer degraded by mixed microorganisms

Abstract

The invention discloses a preparation method of a seaweed fertilizer degraded by mixed microorganisms. The preparation method comprises the following steps of performing cutting up, performing homogenating, performing microbial degradation, performing filtration, performing initial inspection, performing sterilization, and performing rechecking so as to prepare finished products, wherein the step of microbial degradation is performed through the following steps in sequence: firstly, adding trichoderma spp, then adding streptomycesgriseus and pseudomonad. According to the preparation method disclosed by the invention, the mixed microorganisms of the trichoderma spp, the streptomycesgriseus and the pseudomonad are added, and homogenated phaeophyceae is subjected to temperature-controlled aerobic fermentation, so that microorganism strains can be sufficiently cultivated, rapid degradation is realized, strain dosage is reduced, the cost is reduced, and the yield is increased. The prepared seaweed fertilizer finished products have the function of replacing a pesticide for controlling mycotic plant diseases, and particularly have good control effects on brown rots of peach trees.

Description

technical field [0001] The invention relates to the technical field of seaweed fertilizer, in particular to a method for preparing seaweed fertilizer degraded by mixed microorganisms. Background technique [0002] Seaweed fertilizer refers to the use of large algae growing in the ocean as raw materials, through chemical, physical or biological methods, to extract the active ingredients in seaweed, make fertilizer, and apply it to plants as nutrients, which can promote plant growth and improve yield and improve the quality of agricultural products. [0003] At present, most manufacturers at home and abroad mainly use chemical hydrolysis to produce seaweed fertilizer. The biggest disadvantage of chemical hydrolysis is that strong alkali and high temperature destroy the activity of endogenous substances in seaweed. There are many such products, such as cheap seaweed fertilizer produced by small domestic manufacturers. . [0004] The principle of biological fermentation method...

AI Technical Summary

Problems solved by technology

The preparation methods disclosed in the above two documents mainly have the following defects: 1. The mixing of various microbial strains causes mutual inhibition between the various strains, so that the various strains cannot be fully cultivated in the aerobic fermentation stage, so the fermentation time is long. The consumption of microbial strains is large and the cost is high. For example, in a kind of microbial organic seaweed fertilizer and its preparation method disclosed by the notification number CN104446812A, the weight ratio of raw materials to bacterial strains is about 10:1, resulting in a fermentation time of 20 days. 2. A variety of raw materials are mixed, and there are also problems such as long fermentation time, large consumption of microbial strains, and high cost
