Abstract

The invention discloses a method for controlling the growth of compost substrate festuca arundinacea by using modified nano carbon. The method comprises the steps of: sealing the lower end of each PVC pipe of which the diameter is 3cm and the height is 25cm with a layer of cotton cloth and a nylon net, mixing garbage compost and all modified nano carbons uniformly in proportion, and charging 150g of mixed material into each pipe; passivating for 7 days, sowing 0.2g of festuca arundinacea seeds in each pipe, controlling the temperature to be 19-27 DEG C and the relative humidity to be 60-72% during experiment, supplementing water to the compost every day so that the moisture of the compost reaches 70% of field capacity, balancing for 30 days in a laboratory, and measuring; wherein the adding amount of each modified nano carbon is 1-5%(w/w) of the weight of the garbage compost. Experimental results show that the growth of the compost substrate festuca arundinacea is promoted by adding the modified nano carbon.

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 regulating the growth of tall fescue on compost matrix lawns by modified 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 dis...
