Problems solved by technology

The establishment and maintenance of beneficial microbial flora can promote root growth and its function. On the contrary, if the diseased microbial flora dominates, the root system will be poorly developed, the root system function will be damaged, the growth of the aboveground part will be inhibited, and the yield and quality of crops will be reduced. decline

Embodiment 1

[0023] A seaweed-based soil beneficial microbial accelerator is prepared from the following raw materials in parts by weight: 110 parts of alginic acid, 70 parts of chitosan oligosaccharide, 15 parts of inulin, 8 parts of fructooligosaccharide, and 4 parts of polylysine , 3 parts of garlic polysaccharide, 8 parts of seaweed polysaccharide, 0.5 part of cysteine.

[0024] The molecular weight of the alginic acid is 100KDa-150KDa.

[0025] Described garlic polysaccharide is prepared by following steps:

[0026] 1) Wash the fresh garlic, remove the garlic skin, and crush it to obtain garlic slurry;

[0027] 2) Add 6 times the mass of water to the garlic slurry, cook at 90°C for 1 hour, keep warm for 0.5 hour, cool to room temperature naturally, centrifuge, and take the supernatant;

[0028] 3) Filter the supernatant through an ultrafiltration membrane with a molecular weight of 10KDa-20KDa to obtain a crude extract;

[0029] 4) Adjust the pH of the crude extract to neutral, dec...

Abstract

The invention discloses a seaweed soil beneficial microorganism promoter which is prepared from, by weight, 100-120 parts of alginic acid, 60-80 parts of chitosan oligosaccharide, 10-20 parts of inulin, 5-10 parts of fructo-oligosaccharide, 3-5 parts of polylysine, 2-4 parts of garlic polysaccharide, 5-10 parts of algal polysaccharideand 0.5 part of cysteine. The seaweed soil beneficial microorganism promoter is reasonable in formulation, components are synergistic, and the promoter can well promote increase of beneficial microorganism flora in soil to form reasonable soil flora structure.

Description

technical field [0001] The invention belongs to the technical field of soil improvement, and in particular relates to a seaweed soil beneficial microorganism accelerator. Background technique [0002] Soil is one of the main resources for human survival and an important part of the human ecological environment. Soil consists of 45% inorganic matter, 5% organic matter, 25% water and 25% air. Soil is usually layered, with the top layer being the top layer, which contains humus, plant roots, and living animals (such as microbes and earthworms), and the more humus, the more fertile the topsoil. On certain grounds, such as forests, there is so much humus that forms an insulating layer. Below the topsoil is the subsoil, which may contain a greater proportion of clay and less organic matter. Below the subsoil is weathered rock, and below that is a hard bedrock. [0003] Soil structure is the size and spatial arrangement of soil solid particles (including aggregates), which not ...
