Abstract

The invention relates to a preparation method of a composite microbial agent nutrition bowl. The method comprises the following steps: S1: performing beach silt pre-treatments; S2: performing orderedmesoporous medium loading: adding a certain amount of a dispersant, a stabilizing agent and an ordered mesoporous medium to the treated beach silt in the step S1, fully string the mixture for 1-2 h toperform uniformly mixing, and then performing degassing in vacuum and/or ultrasonic wave; S3: performing drying: placing the materials in the step S2 into a dryer, and performing drying at 80-105 DEGC to make the moisture content of the materials be 20-30%; and S4: performing compounding: uniformly mixing the beach silt in the step S3 and a microbial agent, and then performing molding to preparethe composite microbial agent nutrition bowl finished product. According to the method, the coastal beach silt is used as the raw material, the silt is simple in component, the organic matter contentis high, and the nitrogen and phosphorus element contents are high. The composite microbial agent nutrition bowl prepared through the reasonable proportion has porous permeability and nutrient slow release performances, and thus the composite microbial agent nutrition bowl is beneficial to seed germination and survival rate.

Description

technical field [0001] The invention relates to a method for preparing a compound microbial agent nutritional bowl, in particular to a method for preparing a compound microbial agent nutritional bowl by treating tidal mud. Background technique [0002] Our country has a vast coastline and rich tidal mud resources containing a lot of nutrients. In addition to muddy beaches that can be used for tidal flat shellfish farming, there are also a large number of sedimentary muddy beaches that are difficult to use. For a long time, it has had a certain negative impact on the natural landscape and ecological environment of the surrounding sea area. The engineering properties of silt are very poor, mainly manifested in high water content, high compressibility, low strength, poor stability, low bearing capacity, slow drainage and consolidation, soft plastic to flow plastic state, etc. The root cause is high water content. If the water content in the sludge can be reduced, its compress...
