Problems solved by technology

[0003] The introduction of Spartina alterniflora into my country in 1979 has achieved certain economic benefits, but Spartina alterniflora has also caused many problems: blocking waterways, affecting tidal flat farming, causing water quality to decline, inducing red tides, destroying the habitat of offshore organisms, and threatening the local coastal ecosystems, etc.
No matter which control method is adopted, it will consume a lot of manpower, financial resources and material resources.

Embodiment 1

[0022] 1) Harvesting of Spartina alterniflora: Harvest aboveground stems and leaves before heading, at this time Spartina alterniflora has a high crude protein content;

[0023] 2) Post-harvest pretreatment: rinse twice with fresh water, with an interval of 12 hours between each time, rinse the salt precipitated on the plant, and then dry it until the water content is below 23%; then crush the dried Spartina alterniflora into diameters of 5mm -7mm particles;

[0024] 3) Steam fermentation desalination treatment: add 10wt% bran to the pulverized Spartina alterniflora powder; then add water according to the material-to-water ratio of 1:1.3, mix well and stack on the shelf, cover the shelf For the film, pass steam into the film for fermentation, and the temperature is raised to 60°C for 6 hours;

[0025] 4) Culture medium preparation and re-fermentation: add 13% of bran, 6% of corn flour, and 3% of activated carbon to the above-mentioned treated materials based on the dry weight...

Abstract

The invention belongs to the technical field of agricultural microorganisms, and in particular relates to a method for resource utilization of Spartina alterniflora. Firstly, the harvested Spartina alterniflora is processed through a desalination process to partially remove the salinity of Spartina alterniflora; then it is composted and fermented with bran, corn flour, and activated carbon to obtain compost; the compost is used to cultivate resistant Salt edible fungus strains - Pleurotus ostreatus. The method realizes resource utilization of Spartina alterniflora, turns harm into benefit, not only creates economic benefit, but also produces good ecological benefit.

Description

technical field [0001] The invention belongs to the technical field of agricultural microorganisms, and in particular relates to a method for resource utilization of Spartina alterniflora. Background technique [0002] Native to the southeastern coast of the United States, it is a salt marsh plant that grows in the coastal intertidal zone. Belonging to Poaceae and Spartina, it is a perennial herbaceous plant with thick stalks and well-developed root system, which can settle and deposit sediment. In the early 20th century, many countries successively introduced and planted them in large quantities in order to protect beaches and embankments, and promote siltation and land formation. However, because Spartina alterniflora has a strong reproductive capacity in tidal flat wetlands, it seriously threatens the indigenous species of coastal wetlands around the world, and many countries have implemented large-scale control of it as an invasive plant. [0003] The introduction of Sp...
