【 摘 要 】

Recently the area of oil-polluted soil in Northern Shaanxi is increasing rapidly, which seriously affects the health and safety of local people. This experiment studied the effects of different concentrations of oil pollution on the growth status of ryegrass under natural conditions, to provide some evidence for the plant selection of oil-contaminated soil remediation in the study area. The test showed that oil pollution inhibits the normal growth of ryegrass, leading to the decrease of germination rate and plant height and delay of germination time. The higher the oil pollution concentration, the more obvious the growth difference of ryegrass. In the early stage of growth, ryegrass grew rapidly, while slowly in middle and late stage. The result showed that ryegrass can be better adapted to the oil-polluted soil in mild and moderate concentrations, which can be used as a suitable repair plant.
