Method for repairing severe soda-type saline-alkali soil by using Pleurotus eryngii Pleurotus eryngii mushroom bran grass

[0029] The preparation method of embodiment 1. reed-based Pleurotus eryngii mushroom chaff

[0030] Reed-based Pleurotus eryngii fungus chaff is obtained after reed-based Pleurotus eryngii cultivation and harvesting: it is divided into two steps: making reed-based fungus sticks and edible fungus cultivation and management. figure 2 and image 3 It is processed by crushing the chaff of Pleurotus eryngii mushroom. Figure 4 Pre-wet after pulverizing reed straw as a substrate; Figure 5 For the processing and cultivation process of reed-based edible fungus sticks; Figure 6 It is the mycelia development of Pleurotus eryngii.

[0031] 1. Production of reed matrix fungus sticks: reed matrix fungus sticks contain reeds and ingredients as the main material. Among them, the main material reed accounts for 50%-88%, which is the reed straw normally harvested after maturity, and the crushing standard is 0.5-2cm long and 0.1-0.5cm wide strips. Corncobs, bean cakes, gypsum, lime and oth

[0035] 1. Fermentation treatment of bacterial chaff

[0036] After removing the chaff from bag cultivation of edible mushrooms and pulverizing them, add appropriate amount of sand and mix them evenly before fermentation. According to the mass ratio of chaff and sand of 1:2, add water during the fermentation process, and the mass ratio of water to chaff and sand is 1:1. After building the pile, ferment continuously for 15-20 days, and make 1-5 holes in the middle of the fermentation pile for heat dissipation. And use an air thermometer to measure it every day. When the temperature exceeds 60°C, turn the pile to dissipate heat. During the fermentation period, turn the pile about 7-10 times to end the fermentation. During the fermentation process, pay attention to rain protection.
