Embodiment 1
[0022] The formula of the cotton seedling raising substrate that a kind of vinasse biogas residue is made is as follows:
[0023] After distiller's grains pass through the biogas tank to produce biogas, there are 7 cubic meters of fresh biogas residue and 3 cubic meters of vermiculite.
[0024] Distiller's grains biogas residue is the fresh biogas sludge produced by fermentation of distiller's grains in a biogas tank; vermiculite is a clay mineral.
[0025] The method for preparing cotton seedling raising substrate is as follows:
[0026] (1) Drying and dehydrating distiller's grains and biogas residues to a water content of 50-60%;
[0027] (2) Natural stacking and fermentation for 30 days at a fermentation temperature of 50-55°C; turning over every 15 days to obtain the first fermentation;
[0028] (3) Turn the first fermented product, mix the inside and outside of the pile evenly, stack and ferment naturally for 45 days, the fermentation temperature is 60-70°C, turn the p...
Embodiment 2
[0035] The formula of the cotton seedling raising substrate that a kind of vinasse biogas residue is made is as follows:
[0036] 8 cubic meters of fresh biogas residue and 2 cubic meters of vermiculite after the distiller's grains pass through the biogas tank to produce biogas.
[0037] The method for preparing cotton seedling raising substrate is as follows:
[0038] (1) Drying and dehydrating distiller's grains and biogas residues to a water content of 50-60%;
[0039] (2) Natural stacking and fermentation for 40 days at a fermentation temperature of 50-55°C; turning over every 15 days to obtain the first fermentation;
[0040] (3) Turn the first fermented product, mix the inside and outside of the pile evenly, stack and ferment naturally for 52 days, the fermentation temperature is 60-70°C, turn the pile once every 15 days, cool down to 30°C, and obtain the second fermented product, White hyphae appear in the second fermentation, the color is reddish brown, and it has a ...
Embodiment 3
[0047] The formula of the cotton seedling raising substrate that a kind of vinasse biogas residue is made is as follows:
[0048] After distiller's grains pass through the biogas tank to produce biogas, there are 9 cubic meters of fresh biogas residue and 1 cubic meter of vermiculite.
[0049] (1) Drying and dehydrating distiller's grains and biogas residues to a water content of 50-60%;
[0050] (2) Natural stacking and fermentation for 45 days, the fermentation temperature is 50-55°C; turn the pile once every 15 days to obtain the first fermentation product;
[0051](3) Turn the first fermented product, mix the inside and outside of the pile evenly, stack and ferment naturally for 60 days, the fermentation temperature is 60-70°C, turn the pile once every 15 days, cool down to 35°C, and obtain the second fermented product, White hyphae appear in the second fermentation, the color is reddish brown, and it has a rotten aroma;
[0052] (4) Air-dry the second fermented product ...
