Embodiment 1

[0025] Example 1: A small-scale enterprise on the seashore where the Spartina alterniflora community is growing builds a storage device in the factory area. Specific steps are as follows:

[0026] (1) Establish 36 above-ground biological acidification wet storage pools of 100 cubic meters;

[0027] (2) Pretreatment of raw materials of Spartina alterniflora: cutting the harvested aboveground part of Spartina alterniflora into 2-3 cm sections by mechanical means;

[0028] (3) Add 25 tons of fresh raw materials with a moisture content of 70% after pretreatment to each above-ground biological acidification wet storage tank, and add 150 kg of urea to make the carbon-nitrogen ratio 25:1.

[0029] (4) Inoculate 100 kg of biological anaerobic sludge with a water content of 80% in each aboveground biological acidification wet storage tank.

[0030] (5) Add water to each bio-acidification wet storage tank, the addition is 80 tons of water, use a pump to extract the fermented liquid fr...

Embodiment 2

[0033] Embodiment 2: A certain large-scale enterprise establishes a Spartina alterniflora storage base near the roadside on a beach at the edge of a Spartina alterniflora community. Specific steps are as follows:

[0034] (1) Use degraded tidal ditches to build 100 underground biological acidification wet storage pools of 200 cubic meters after reconstruction;

[0035] (2) Putting in the raw material of Spartina alterniflora for pretreatment: cutting the aboveground part of Spartina alterniflora into 2-3 cm sections by mechanical means;

[0036] (3) Add 52 tons of fresh raw materials with a moisture content of 71.15% after pretreatment to each underground biological acidification wet storage pool, and add 300 kg of urea to make the carbon-nitrogen ratio 25:1.

[0037] (4) Add 200 kg of biological anaerobic sludge with a water content of 80% to each biological acidification wet storage tank for inoculation.

[0038] (5) Add water to each bio-acidification wet storage tank, th...

Embodiment 3

[0041] Embodiment 3: A certain large-scale enterprise builds a Spartina alterniflora storage base near the roadside on a beach at the edge of the Spartina alterniflora community in a certain place, and the specific steps for further storage after 1 year of storage are as follows:

[0042] (1) Putting in the raw material of Spartina alterniflora for pretreatment: cutting the aboveground part of Spartina alterniflora into 2-3 cm sections by mechanical means;

[0043] (2) Add pretreated water content of 71.15% and 52 tons of fresh raw materials to each underground biological acidification wet storage pool;

[0044] (3) In each bio-acidification wet storage tank, add the storage tank extraction liquid retained during the previous batch of storage. The addition amount is 170 tons of extraction liquid, and pump it from the bottom of each storage tank with a flow rate of 10 cubic / h. The fermentation broth is circulated to the upper part of the corresponding storage tank for circula...

Abstract

The invention discloses a biological acidifying wet-type storage method of inter-flower rice grass in the resource and light industrial technological domain, which comprises the following steps: grinding the harvested inter-flower rice grass mechanically or artificially, putting in the impermeable pool or ground groove container to compact, seeding, adding water until the water covers the upper surface of inter-flower rice grass by over 10cm, reducing pH value in the circulating ferment container at 5-6 within short time, stopping circulating to keep pH value at 5-6, semi-sealing, reserving.

Description

technical field [0001] The invention belongs to the field of resources and environment, and in particular relates to a biological acidification wet storage method of Spartina alterniflora. Background technique [0002] Spartina aterniflora, native to the United States, is a perennial salt marsh plant that grows in the intertidal zone. In the early 1980s, Spartina alterniflora was introduced into China to protect beaches, promote siltation and build land. The introduction of Spartina alterniflora once played a role in protecting seawall safety, promoting economic development in coastal areas, improving ecological environment, and reducing disasters. made a major contribution. However, after more than 20 years of development, Spartina alterniflora has formed a community of 800,000 to 1,000,000 mu in coastal areas of my country. With the dominant community formed by this alien invasive species, it has brought a series of negative impacts to coastal areas. As an alien species ...
