Embodiment 1
[0015] Ecological Restoration Area: Located in the suburb of Fushun City, Liaoning Province, because it is located at the junction of urban and rural areas, there are many small factories around, and the soil is polluted by polycyclic aromatic hydrocarbons. The average content of polycyclic aromatic hydrocarbons is 4622 μg / kg.
[0016] 1. Selection of restoration plants. The ecological restoration plants use corn, which is widely planted by local farmers and is the main source of agricultural economy. The planting area accounts for more than 70% of the local farmland. The corn growing season is from May 10 to September 30, a total of 140 days.
[0017] 2. Apply high-efficiency microbial agents. The so-called high-efficiency microbial agent is a field-applied agent obtained by multiplying a variety of highly efficient polycyclic aromatic hydrocarbon-degrading bacteria in a matrix with corncobs and soybean bran as raw materials for 5 days. The high-efficiency microbial agent w...
Embodiment 2
[0023] Ecological Restoration Area: Located in Dongling District, Shenyang City, Liaoning Province, this area belongs to the Shenfu sewage irrigation canal area, and the average content of polycyclic aromatic hydrocarbons is 3522 μg / kg.
[0024] 1. Selection of restoration plants. Soybean is selected as the ecological restoration plant, and the plant growth period is from May 15 to October 5, a total of 140 days.
[0025] 2. Apply high-efficiency microbial agents. The so-called high-efficiency microbial agent is a field-applied agent obtained by multiplying a variety of highly efficient polycyclic aromatic hydrocarbon-degrading bacteria in a matrix with corncobs and soybean bran as raw materials for 3 days. The high-efficiency microbial agent was applied to the farmland 10 days before soybean sowing, that is, on May 5, with an application rate of 50 kg / mu. On May 6, the farmland was plowed with a tiller.
[0026] 3. Apply sludge fermentation fertilizer. The so-called sludge...
Embodiment 3
[0030] Ecological Restoration Area: Located in Wanghua District, Fushun City, Liaoning Province, which is a typical urban-rural integration zone, the content of polycyclic aromatic hydrocarbons is 4897 μg / kg.
[0031] 1. Selection of restoration plants. Castor is used as the ecological restoration plant, and the plant growth period is from May 10 to September 30, a total of 140 days.
[0032] 2. Apply high-efficiency microbial agents. The so-called high-efficiency microbial agent is a field-applied agent obtained by multiplying a variety of polycyclic aromatic hydrocarbon-degrading bacteria in a matrix with corncobs and soybean bran as raw materials for 7 days. The high-efficiency microbial bacterial agent was applied to the farmland 5 days before castor sowing, that is, on May 5th, and the application rate was 50 kg / mu, and the farmland was plowed with a tiller immediately after application.
[0033] 3. Apply sludge fermentation fertilizer. The so-called sludge fermentatio...
