Embodiment 1

[0024] (1) evenly sow lawn plants with 40g / square meter in natural soil;

[0025] (2) Cultivate with clean water at the initial stage of sowing, and then irrigate with eutrophic water that dilutes the original concentration of 75% after the seeds germinate;

Embodiment 2

[0028] (1) Experimental materials

[0029] Perennial ryegrass (Lolium perenne L.) and tall fescue (Festuca arundinacea L.), common terrestrial lawn plants in northern my country, were used in this experiment. The experimental water used for irrigation in this experiment is: the waters along the outer ring road, the waters around Yao Village, and the domestic sewage of the main campus of Normal University. The TN of the three waters are: 9.7mg / L, 12.3mg / L, 13.1mg / L; the TP are: 0.6mg / L, 0.9mg / L, 0.8mg / L; the pH values ​​are: 8.12, 8.99, 8.67. Referring to the "National Environmental Quality Standards for Surface Water" (GB3838-2002), the water used in this experiment exceeds the surface water category V standard and reaches the level of eutrophication. Tap water was selected as the control, its TN: 0.16mg / L; TP: 0.01mg / L; pH: 6.89.

[0030] (2) Development method

[0031] The three eutrophication waters were diluted with tap water to 25%, 50%, and 75% of the original concen...

Abstract

The invention discloses an application of eutrophic water in the regulation of antioxidase activity of lawn plants, wherein the eutrophic water is the eutrophic water with 25 percent-75 percent of the original concentration; and the eutrophic water has TN of 9.7 mg/L-13.1mg/L, TP of 0.6mg/L -0.9mg/L and pH value of 8.12-8.99, wherein the activity of antioxidase comprises of superoxide dismutase, peroxide dismutase and catalase. Results show that the diluted eutrophic water is applied to irrigation to reinforce the activity of a protective enzyme system of lawn plants, thereby being capable of obviously improving the resistance ability of the lawn plants to adverse growing environment and providing technical support for the application of the eutrophic water in a lawn plant establishment system.

Description

technical field [0001] The invention belongs to the technical field of environmental protection and relates to a treatment method for urban eutrophic water. More specifically, a method for modulating antioxidant enzymes in turfgrass plants using nutrient-rich water. Background technique [0002] Eutrophic water body is the discharge of excessive nutrients (mainly nitrogen, phosphorus, etc.) in natural water bodies, which causes abnormal reproduction of various aquatic organisms and plants and changes in the ecological balance of the entire water body, resulting in deterioration of water quality and odor. It is a pollution phenomenon that the function of water body is destroyed, which leads to the accelerated development of eutrophication process of water body. Once the water body enters the eutrophic stage, it will have a great negative impact on people's living environment, and ultimately affect economic construction and social development. Tianjin is not only a city with...
