Embodiment 1
[0015] In the specific implementation of the present invention, a method for utilizing bacterium residue and Sorbus dandelion to restore chromium-contaminated soil comprises the following steps:
[0016] (1), bacteria residue treatment
[0017] Use waste mushroom sticks (bacteria residue) after cultivation of shiitake mushrooms. The raw materials of the bacteria sticks are made of: 83% of hard wood of broad-leaved trees, 15% of wheat bran, 1% of gypsum powder and 1% of sugar, and are autoclaved at 121°C for 25 minutes. , air-dried and crushed, passed through a 20-mesh sieve, and set aside;
[0018] (2) Sprinkle the air-dried and pulverized fungus residue evenly on the surface of the chromium-contaminated soil at a rate of 150 kg / mu, plow the soil 20 cm, rake it flat, and plant Sorrel grass after 6 days, with a row spacing of 45 cm and a seeding rate of 3 kg / mu. The depth is 4cm, cover the soil in time, water regularly during the plant growth process, manage according to the n...
Embodiment 2
[0020] A kind of method of the present invention utilizes bacterium slag and Sorbus dandelion to restore chromium-contaminated soil, comprising the following steps:
[0021] (1), bacteria residue treatment
[0022] Use waste mushroom sticks (bacteria residue) after cultivation of shiitake mushrooms. The raw materials of the bacteria sticks are made of: 82% hard wood of broad-leaved trees, 16% wheat bran, 0.9% gypsum powder and 1.1% sugar, and are autoclaved at 121°C for 25 minutes. , air-dried and crushed, passed through a 20-mesh sieve, and set aside;
[0023] (2) Spread the air-dried and pulverized fungus residue evenly on the surface of the chromium-contaminated soil at a rate of 120 kg / mu, plow the soil 17 cm, rake it flat, and plant Sorrel grass after 5 days, with a row spacing of 42 cm and a seeding rate of 2.6 kg / mu. The sowing depth is 4cm, cover the soil in time, water regularly during the plant growth process, manage according to the normal growth requirements of So...
Embodiment 3
[0025] A kind of method of the present invention utilizes bacterium slag and Sorbus dandelion to restore chromium-contaminated soil, comprising the following steps:
[0026] (1), bacteria residue treatment
[0027] Use waste mushroom sticks (bacteria residue) after cultivation of shiitake mushrooms. The raw materials of the bacteria sticks are made of: 84% hard wood of broad-leaved trees, 14% wheat bran, 1.1% gypsum powder and 0.9% sugar. Autoclaved at 121°C for 25 minutes , air-dried and crushed, passed through a 20-mesh sieve, and set aside;
[0028] (2) Spread the air-dried and pulverized fungus residue evenly on the surface layer of the chromium-contaminated soil at 190kg / mu, plow the soil 23cm, rake it flat, and plant Sorbus dandelion after 7 days, with a row spacing of 48cm and a seeding rate of 3.4kg / mu. The sowing depth is 5cm, cover the soil in time, water regularly during the plant growth process, manage according to the normal growth requirements of Sorbus dansana,...
