[0121] Step 5. Compact the substrate, and pour the rooting water, and no artificial maintenance is needed subsequently.

[0122] Test the growth state of the ecological greenery restoration native plant, and the determined indexes include the average survival rate, average plant height growth amount (only record the stem length for the liana), average crown width growth amount and growth state. After planting, the indexes of each plant are determined at the 10th, 20th, 30th, 40th, 50th, 60th, 75th, 90th, 120th, 150th, 180th, 210th, 240th, 270th, 300th and 330th day, and finally the average value is taken. The average survival rate (%) = (the total number of finally survived plants - the total number of initial plants) / 3 x 100 / 100; the average plant height growth rate (%) = (the plant height value of the last measurement - the initial plant height) / 3 x 100 / 100; and the average crown width growth rate (%) = (the last crown width value of the last measurement - the initial crown width) / 3 x 100 / 100.

[0123] The survival rate, plant height growth rate, crown width growth rate and growth state of the 10 kinds of stone slope native ecological greenery restoration plants are shown in the following table.

[0124]

[0125] Note: The plant height growth rate or the crown width growth rate is more than 90% for excellent, the growth rate is between 50% and 90% for good, the growth rate is less than 50% for medium, and the growth rate is 0 or the plant is dead for poor.

[0126] It can be seen that the embodiment 1 of the present application is suitable for the growth of various plants, and the survival rate of only two species is less than 100%, but is not less than 90%, and no mortality rate occurs; and the growth state does not appear in the medium or below grade.

[0127] The same test method is used for the comparative examples 1 and 2, and the test results are as follows:

[0128] Hibiscus: crown width 40 cm (plant height 100 cm) bag seedlings, 18 plants. The average plant height growth rate is 8.8% (increased by 8.8 cm / year), the average crown width growth rate is 34.3% (increased by 13.7 cm / year), and the growth state is medium.

[0129] Avens: crown width 40 cm (plant height 60 cm) / pot seedlings, 9 plants. The average plant height growth rate is 23.7% (increased by 14.2 cm / year), the average crown width growth rate is 8.4% (increased by 3.4 cm / year), and the growth state is medium.

[0130] It can be seen that, compared with Comparative Examples 1-2, by using yellow mud, the root fixation performance of the substrate is improved; by using fermented peanut shells, the soil aggregate structure can be improved, and the soil water and fertilizer retention capacity can be improved. This good water and fertilizer retention capacity can significantly improve the water retention performance and nutrient storage capacity of the substrate, and is especially suitable for the climate characteristics of alternating rain and seasonal drought in South China. The loose structure can also increase the air permeability of the substrate, provide sufficient oxygen for plant root respiration, and is also conducive to the activity and reproduction of microorganisms; the fermented peanut shells are a long-acting organic fertilizer, which is very suitable for the case where there is no artificial maintenance after planting; by using sand, the aggregate structure of the yellow mud is improved, the permeability is increased, the formation of hardening is inhibited, the plant root system is stretched, and the soil fertility can be adjusted; by using mushroom residue, the mushroom residue contains rich cellulose, hemicellulose and a small amount of protein and other nutrient components, which can improve the physical structure of the substrate after treatment, increase the porosity of the substrate, and improve the air permeability and water retention.

[0131] In summary, the embodiments of the present application have the following beneficial effects:

[0132] Improve plant growth conditions: the good water and fertilizer retention, air permeability and acid adaptability of the substrate can provide stable growth conditions for plants in South China, increase the survival rate of plants by more than 50%, and the plants are healthy and robust, and the stress resistance (resistance to heavy rain, drought and diseases and pests) is enhanced.

[0133] Improve regional ecological environment: the vegetation coverage of high and steep slopes in South China is significantly improved, the vegetation structure of trees, shrubs and grasses increases the regional vegetation diversity, purifies the air, regulates the local microclimate, conserves water, and promotes the recovery and stability of the regional ecological system, providing a suitable habitat for local animals and plants.

[0134] Reduce labor costs: due to the good water and fertilizer retention, air permeability and acid adaptability of the substrate, the plants do not need artificial maintenance after planting, which greatly reduces the labor input and further reduces the overall cost of the slope ecological greening project.

[0135] Promote regional technology progress: the invention provides a core carrier for the growth of ecological greening plants of high and steep slope in the south China region according to the unique matrix of the characteristics of the south China region, and can effectively promote the development of the ecological restoration engineering field in the south China region, and has strong regional popularization value.

[0136] Finally, it should be noted that the above examples are only used to illustrate the technical solutions of the present application, not to limit them. Although the present application has been described in detail with reference to the above examples, those skilled in the art should understand that the specific embodiments of the present application can be modified or replaced by equivalents after reading the present application. However, these modifications or changes are still within the scope of the present application.
