Embodiment 1
[0023] A method for making a cultivation substrate based on crop stalks, comprising the following steps:
[0024] 1) adjusting the moisture content of the crop straw to 45%, adding beneficial mixed bacteria of mold and Bacillus licheniformis to the crop straw, stirring evenly, so that the concentration of the mixed bacteria in the crop straw is greater than 100,000 / gram of the crop straw;
[0025] 2) carry out stockpiling, cover with black plastic film after stockpiling, carry out anaerobic fermentation 10 days;
[0026] 3) Uncover the plastic film, sprinkle a layer of composite bacteria mixed with Bacillus subtilis, Aspergillus oryzae and saccharomyces. The concentration of composite bacteria in the pile is 500,000 / g pile, turn over the pile, and start aerobic fermentation;
[0027] 4) During aerobic fermentation, turn the pile at intervals. When the moisture in the pile is lower than 30% and the temperature is lower than 30°C, add 0.5Kg of superabsorbent resin per cubic sub...
Embodiment 2
[0029] A method for making a cultivation substrate based on crop stalks, comprising the following steps:
[0030] 1) adjusting the moisture content of the crop straw to 48%, adding beneficial mixed bacteria of mold and Bacillus licheniformis to the crop straw, stirring evenly, so that the concentration of the mixed bacteria in the crop straw is greater than 100,000 per gram of crop straw;
[0031] 2) carry out stockpiling, cover with black plastic film after stockpiling, carry out anaerobic fermentation 12 days;
[0032] 3) Uncover the plastic film, sprinkle a layer of composite bacteria mixed with Bacillus subtilis, Aspergillus oryzae and saccharomyces. The concentration of composite bacteria in the pile is 500,000 / g pile, turn over the pile, and start aerobic fermentation;
[0033] 4) During aerobic fermentation, turn the pile at intervals. When the moisture in the pile is lower than 30% and the temperature is lower than 30°C, add 0.8Kg of superabsorbent resin per cubic sub...
Embodiment 3
[0035] A method for making a cultivation substrate based on crop stalks, comprising the following steps:
[0036] 1) adjusting the moisture content of the crop straw to 50%, adding beneficial mixed bacteria of mold and Bacillus licheniformis to the crop straw, stirring evenly, so that the concentration of the mixed bacteria in the crop straw is greater than 100,000 / gram of the crop straw;
[0037] 2) carry out stockpiling, cover with black plastic film after stockpiling, carry out anaerobic fermentation 15 days;
[0038] 3) Uncover the plastic film, sprinkle a layer of composite bacteria mixed with Bacillus subtilis, Aspergillus oryzae and saccharomyces. The concentration of composite bacteria in the pile is 500,000 / g pile, turn over the pile, and start aerobic fermentation;
[0039] 4) During aerobic fermentation, turn the pile at intervals. When the moisture in the pile is lower than 30% and the temperature is lower than 30°C, add 0.6Kg of superabsorbent resin per cubic sub...
