Embodiment 1

[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 ...

Embodiment 2

[0034] Example 2. A method of using reed-based Pleurotus eryngii fungus chaff to plant grass to repair severe soda-type saline-alkali soil

[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.

[0037] 2. Bacteria chaff is mixed into the severe saline-a...

Abstract

The invention discloses a method for repairing severe soda-type saline-alkali soil by using Pleurotus eryngii Pleurotus eryngii mushroom bran grass, and belongs to the technical field of environment. The problems of mushroom bran resource utilization, soda type severe saline-alkali soil treatment and rapid vegetation recovery are solved. The method provided by the invention comprises the following steps: (1) fermentation treatment of reed-based pleurotus eryngii fungus chaff: mixing the fungus chaff with sandy soil, and fermenting; (2) mixing the reed-based pleurotus eryngii fungus chaff to a plough layer of the severe saline-alkali soil: paving the treated fungus chaff obtained in the step (1) on the severe soda saline-alkali soil, then carrying out rotary tillage and uniform mixing, and then irrigating; (3) planting Chinese wildrye or reed rhizomes; and (4) after transplanting, supplementing water. And resource utilization of mushroom bran nutrition is realized.

Description

technical field [0001] The invention belongs to the field of environmental technology, and in particular relates to a method for repairing severe soda-type saline-alkali soil by using reed-based Pleurotus eryngii fungi to grow grass. Background technique [0002] The western part of the Songnen Plain is located in the semi-arid and semi-humid transition zone. It is the largest soda saline land in China and one of the three largest distribution areas of soda saline land in the world (Li et al., 2017). Leymus chinensis is the main grassland type distributed in the west of the Songnen Plain. Leymus chinensis is a high-quality forage grass and the climax vegetation of saline-alkali grassland. In the past 50 years, the area of ​​saline-alkali land in the western Songnen Plain has increased by 1.73 times, and grassland degradation is one of its main sources (Yang et al.2010). Saline-alkali land control and grassland vegetation restoration are important ecological problems to be s...
