Embodiment 1

[0082] (1) Tall fescue with full and uniform grains was selected as the turf plant for the study, from August to September, for a total of 30 days; during the test period, the highest temperature was 33°C, the lowest temperature was 18°C, and the average temperature was 24°C , the average humidity is 45%;

[0083](2) The experimental field was weeded, fully plowed, naturally ventilated, and leveled after 2 days. The thickness of the finishing substrate was about 15cm. The total area of ​​the experimental field was 165cm×75cm+180cm×30cm. The area of ​​the plot is 30cm×30cm, and the plots are separated by 15cm to reduce the mutual influence between the plots, and each plot is sown with 3g;

[0084] (3) 300g, 600g, and 900g of air-dried sludge were applied to the plot, and the substrate was fully watered to ensure the smooth germination of seeds and initial growth of seedlings in the initial stage of cultivation. During the planting period, the experimental field was manually wa...

Abstract

The invention discloses a method for improving lawn forming quality through applying air-dried sludge substrate. The method comprises the steps of selecting full tall fescue seeds as a lawn planting material, applying 300g, 600g and 900g of air-dried sludge to test fields respectively, and watering the substrate fully to guarantee smooth germination of the seeds at an initial cultivation stage and growth of seedlings at an initial stage; and selecting five plants from treated quadrats after cultivation for 30 days and measuring vertical heights of the seedlings. Experimental results prove that due to application of the air-dried sludge under the natural condition, accumulation of above-ground biomass of the tall fescue is promoted, increase of the lawn plant density is promoted, and the chlorophyll content is increased, so that the lawn quality is improved, meanwhile, the plant membrane lipid peroxidation product content is reduced, and environmental adaptability of lawn plants is improved effectively.

Description

technical field [0001] The invention belongs to the technical field of environmental protection and relates to urban afforestation, in particular to a method for directly applying substrates by using air-dried sludge to improve the quality of lawn formation. Background technique [0002] Municipal sludge is the sediment produced by urban sewage treatment plants after various levels of treatment and purification of sewage. Its composition is related to the source of sewage, treatment technology, living standards and dietary structure of urban residents. But most municipal sludge contains a lot of organic matter and contains nutrients needed for plant growth. Studies have shown that the nutrients and organic matter content in the sludge of 29 sewage treatment plants in 16 cities in my country are different. The content of organic matter and macronutrient elements in urban sludge in the region is relatively high. In my country's municipal sludge, the highest organic matter con...
