Embodiment 1

[0018] (1) The garbage compost is rinsed with water and compost at a mass ratio of 1:1 or 2:1, left for one day, and set aside;

[0019] (2) Evenly sow ryegrass at 20g / square meter on the repaired garbage composting surface;

[0020] (3) The watering method is to water once in the morning and evening to keep the substrate surface moist;

[0021] (4) On the 30th day, the content changes of superoxide dismutase, superoxide dismutase and catalase were measured. See the method of embodiment 3 for details.

Embodiment 2

[0023] (1) The garbage compost is rinsed with water and compost at a mass ratio of 3:1, placed for one day, and set aside;

[0024] (2) Evenly sow ryegrass at 40g / square meter on the repaired garbage composting surface;

[0025] (3) The watering method is to water once in the morning and evening to keep the substrate surface moist;

Embodiment 3

[0028] (1) Test material

[0029] Perennial ryegrass and tall fescue were selected as test materials in this experiment. Domestic waste compost comes from Tianjin Xiaodian Composting Plant, and its basic physical and chemical properties and background values ​​of heavy metal content are shown in Table 1.

Abstract

The invention discloses application of remedied domestic waste composts in adjusting the activities of antioxidant enzymes of lawn plants; wherein, the remedied waste composts refer to compost matrixes obtained by eluting the composts with water based on the weight ratio of 1:1-3; the activities of the antioxidant enzymes comprise superoxide dismutase, peroxide dismutase and catalase. The technical effects of the invention show that the method of planting lawn plants on the remedied waste composts not only can enhance the activities of the protective enzyme systems of the lawn plants but also can improve the capabilities of the lawn plants in resisting unfavorable growth environment obviously, therefore, the technology not only finds a way for scientifically and effectively planting environment-friendly lawns on the matrixes of the eluted compost, but also can achieve the purpose of reducing the environment pollution caused by the domestic waste composts and provide technical support for applying the remedied waste composts to the lawn planting system.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and relates to a reasonable and safe use method for composting municipal domestic garbage. More specifically, the application of remediation litter compost to regulate the activity of antioxidant enzymes in turfgrass plants. Background technique [0002] With the increase of the number of cities in our country, the acceleration of urbanization process, the expansion of scale, the increase of recognition, the improvement of people's living standards and the change of lifestyle, the output of urban domestic waste has increased rapidly at an average annual growth rate of 8% to 10%. At the same time, the composition and characteristics of ingredients have also undergone obvious changes. Composting domestic waste can not only solve the problem of urban waste, but also achieve the purpose of recycling, which has certain economic and social benefits. At present, all countries in the wo...
