Abstract

The invention discloses a method for improving the reproducibility of soil matrix lawn grass through modified nanocarbon, wherein a plastic flower pot with the height of 25cm and the diameter of 12cm is adopted, a gauze is cleaned, dried and sheared into a proper-size round shape to fix the bottom of the flower pot, 2kg garden soil matrix is weighed in each container, the modified nanocarbon whose weight is 1-5% that of the garden soil matrix is added into the garden soil, 4.5g festuca arundinacea seeds are sown, water is fed timely and quantitatively every day during the experiment to meet the plant growth needs, the plant is cultured in a lab at the temperature of 25-34 DEG C and the relative humidity of 31%-48%, the light condition is natural incident light, the experiment is conducted for 120 days, the part of the festuca arundinacea on the ground is clipped on the sixtieth day of the experiment, 1cm crop is kept, the biomass of the first crop is measured, and the biomass of the second crop is measured at the end of the experiment. The experiment results show that 5% HNO3 modified nanocarbon can improve the reproducibility of the soil matrix festuca arundinacea.

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 improving the regeneration of soil matrix turfgrass by modifying nano-carbon. Background technique [0002] In the construction of lawn planting system, the method of laying turf is very common in cities at home and abroad. The turf is a lawn plant or lawn planting material that the lawn is flattened into a flat shape or stripped into squares, rectangles, columns and other shapes of different sizes, with a certain amount of soil attached thereto. At present, turf has become a hot-selling product in some countries, and the sales value of turf in the United States alone exceeds 10 billion US dollars per year. The prospect of turf production in my country is also broad, and the price per square meter in many cities is as high as 10 yuan. Although the application of turf establishment is very popular, its disadvantag...
