Embodiment

[0019] Example: Pilot test of petunias repairing oil-contaminated soil plots

[0020] The test was carried out in 2008 (2008.4.27-2008.7.27) for a total of 127 days. The test site was selected in the Tianjin Agricultural Environmental Protection Research Institute of the Ministry of Agriculture. The station is located in Nankai District, Tianjin City, which belongs to the warm temperate semi-humid continental climate. The original oil-contaminated soil used in the test was taken from Shengli Oilfield, Dongying City, Shandong Province, and the clean soil was taken from Xiqing District, Tianjin City. After the two kinds of soils are naturally air-dried, pass through a 4mm sieve and then prepare the required concentration in proportion. There are 5 treatments in the experiment, namely: CK (clean soil), the concentration of petroleum hydrocarbon pollutants is soil A: 0.5% (5,000mg / kg), soil B: 1.0% (10,000mg / kg), soil C: 2.0% (20,000mg / kg), soil D: 4.0% (40,000mg / kg), each treatm...

Abstract

The invention relates to phytoremediation technology for organic poison polluted soil, in particular to a method for restoring petroleum-polluted soil by utilizing an ornamental plant, namely morning glory. The method adopts the technical proposal that adequate sand is doped into the petroleum-polluted soil; morning glory seeds are soaked by distilled water until seed hulls are expanded and cracked, and subjected to spot seeding into petroleum hydrocarbon polluted soil; and the morning glory planted in the petroleum hydrocarbon polluted soil adopts outdoor planting and watering at a fixed period, and the water content of the soil is maintained to be 70 to 80 percent of the field capacity. Compared with the prior method for treating the petroleum-polluted soil, the method has the advantages of small investment, small engineering quantity, low technical requirements and so on, and can not cause secondary pollution, and simultaneously the restoring process not only can not damage the ecological environment of the soil but also helps to improve soil degradation and productivity reduction caused by petroleum hydrocarbon pollution and recover and improve the biodiversity of the soil.

Description

technical field [0001] The invention relates to a phytoremediation technology for soil polluted by organic poisons, in particular to a method for repairing oil-polluted soil by using an ornamental plant morning glory. Background technique [0002] The rapid development of the industrial economy in the last century has resulted in the release of a large number of man-made chemicals into the natural environment. Among them, petroleum, as one of the main energy sources of human beings, inevitably causes a lot of pollution to the surrounding environment during its extraction, storage, transportation, and processing [Document 1: Karen E. Gerhardt, Xiao-Dong Huang, Bernard R. Glick et al, 2008. Phytoremediation and rhizoremediation of organicsoil contaminants: Potential and challenges. Plant Science, 176(2009) 20-30. Literature 2: Paul M.White, JR., Duane C.Wolf, Gregory J.Thoma et al , 2005. Phytomediation of Alkylated Polycyclic Aromatic Hydrocarbons In a Crude Oil-Contaminated...
