Problems solved by technology

However, the greening effects at the bottom of these viaducts and around high-rise buildings are generally unsatisfactory and even become green blind spots. The main reason is that there are different degrees of shading in these areas, especially under the viaducts. The quality of lawns and green spaces is generally poor
Although some areas are covered with shade-growing or shade-tolerant vegetation, they are generally ornamental ground cover plants that are not resistant to trampling. Therefore, citizens can only look at the "green" and sigh, and cannot step into it, which greatly limits the opportunities for public activities and rest. space

Embodiment 1

[0012] Embodiment 1: In a park in Guangzhou City, under a plurality of sparse forests, the shading rate is 30% to 70%, and the test is carried out with a total area of ​​about 2 hectares:

[0013] 1. Loosening and leveling the land, clearing understory weeds;

[0014] 2. Select obtuse leaf grass seedlings for stem node cutting propagation. First remove part of the leaves on the cuttings, and then fold them into small sections about 10cm long. Each small section contains 1 to 2 stem nodes, and then press about 10cm×10cm. Plant the cuttings into the soil with the distance between the plants and the rows, one end of the stem node is buried in the soil, the implantation depth is 4-5cm, and the root water is poured;

[0015] 3. If it does not rain, water once every 1 to 2 days until the blunt-leaved grass turns green and starts to grow (generally it turns green and grows in about 4 to 6 days). After 4 to 6 months of growth, a dense and emerald green lawn will be formed. During th...

Embodiment 2

[0016] Embodiment 2: In the compound of a certain unit in Guangzhou City, the experiment was done with the soil of many plots in front of and behind the house, with a total area of ​​about 0.5 hectares. Prepare the land first, remove weeds, and use blunt-leaved grass seeds for some plots, at a rate of 20g / m 2 Density sowing, part of the plots are planted with blunt-leaved grass seedlings, other management measures are the same as in Example 1, the first cutting is carried out after 2 months, and the cutting is carried out every 1 to 1.5 months thereafter, and finally obtained Achieved the same lawn effect as in Example one.

Embodiment 3

[0017] Example 3: A blank strip at the bottom of a viaduct in Guangzhou, with an area of ​​about 300m 2 , almost no sunlight all year round, with a shading rate of 90%. First, the soil in the blank zone is loosened and leveled. Because the soil is very poor, a certain amount of organic fertilizer is applied as a base fertilizer. The obtuse leaf grass seedlings will be implanted in the soil with a plant row spacing of about 10cm×10cm, and the same management will be carried out according to Embodiment 1. After planting for 5 months, a dense and emerald green lawn will be formed.

Abstract

A planting method of shade-tolerant turf chracterized in that a warm season turfgrass--- Augustinegrass (Stenotaphrum helferi Munroex Hook.f.) with great shade-tolerance and trampling resistance is chosed, and which seeds or seedling is suitable,but seedling is preferabe. The invention has the advantages that: first, Augustinegrass has great shade tolerance and keeps normal growth in the condition that 90% is shaded off; second, in the condition that less than 80% is shaded off, the more are shaded off, the bright greener Augustinegrass grows; third, Augustinegrass is originally planted in hainan and other places in our country and is easy to be planted, to survive, and to be managed, which forms densed turf in a short time; fourth, it is no need to fertilize Augustinegrass which has acid-tolerance and slim-tolerance, besides it is scarcely to have pest and disease damage; fifth, Augustinegrass will not spread around with a little management, so it will not become a poisonous weed.

Description

technical field [0001] The invention relates to the establishment and planting of urban lawns and green spaces, that is, a method for establishing and planting shade-tolerant lawns. Background technique [0002] Lawns and green spaces are an important symbol of modern urban civilization and a major demand for the spiritual life of urban residents. At present, the construction of lawns and green spaces in many cities in my country is developing rapidly, and the coverage rate of urban green spaces has generally been improved. But at present, the lawns built and planted in my country's cities are generally not shade-tolerant, and these lawns are difficult to form lawns around high-rise buildings, under viaducts and in urban sparse forests, or even cannot survive. As we all know, my country's urban construction has developed rapidly in the past ten years. Viaducts cross the streets and alleys of the city, and high-rise buildings have sprung up like mushrooms after rain. Howeve...
