[0002] Low-maintenance plant landscape aims to solve the problems of excessive post-maintenance and high maintenance costs that are currently common in plant landscapes through reasonable plant selection, scientific design methods, and construction and management technologies. The near-natural design method enables plants to achieve ecologically sustainable development. Low-maintenance plant landscapes greatly save energy resources and labor, and are a powerful measure to achieve an economical garden. At present, there are also many problems in the creation of plant landscapes, such as the lack of scientific combination, maintenance and management, which do not conform to ecological laws. Plant landscapes not only cannot give full play to their landscape and ecological benefits, but also require a lot of maintenance in the later stage, which increases the cost of landscape construction and is prone to the problem of lack of later maintenance due to insufficient financial resources.

[0019] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0020] Example: Figure 1 As shown, a low-maintenance plant ecosystem includes a plant landscape 1, an ecological grass-planting ditch 2 located on the side of the plant landscape 1, and an overflow well 3 located between the ecological grass-planting ditch 2 and the plant landscape 1. The top of the ecological grass-planting ditch 2 is connected to the overflow well 3 through an overflow pipe 4. After the ecological grass-planting ditch 2 reaches a certain overflow water level, it flows to the overflow well 3 through the overflow pipe 4. A filter device is installed at the input end of the overflow pipe 4. The filter device is a filter net, which is used to filter debris, silt, etc. to prevent rainwater from washing silt or debris into the overflow pipe 4, thereby blocking the overflow pipe 4. A submersible pump 5 is provided at the bottom of the overflow well 3. The water outlet of the submersible pump 5 is connected to the spray main pipe through a water pipe 6. The spray main pipe is connected to multiple spray branch pipes 7. Multiple spray heads 8 are installed on the spray branch pipe 7. The spray branch pipe 7 is installed at the ground end of the plant landscape 1. A liquid level meter 24 is installed in the overflow well 3, which can set the minimum value and normal value of the liquid level in the overflow well 3. When the liquid level in the overflow well 3 is lower than the minimum value, external water supply is required; when the liquid level in the overflow well 3 reaches the normal value, under the action of the submersible pump 5, it passes through the water pipe 6 and the sprinkler main pipe in turn, and then is diverted and transported to the sprinkler branch pipe 7, and sprayed through the sprinkler head 8, so that the plant community on the ground end of the plant landscape 1 can be irrigated, reducing the need for plant maintenance.

[0021] The ecological grass-planting ditch 2 is provided with a first soil compaction layer 12, a first gravel layer 13, a first gravel filter layer 14, a first planting layer 15 and a pebble layer 16 from bottom to top. The pebble layer 16 is spread with 20mm-40mm pebbles on the first planting layer 15, so that when water penetrates from the pebble layer 16, it will not take away the soil beside it, and prevent pipe bursts and soil flow. A permeable geotextile is provided between the first gravel layer 13 and the first gravel filter layer 14. The permeable geotextile has excellent filtering and protective effects, high tensile strength and good permeability. When rainwater flows from the first gravel filter layer 14 through the permeable geotextile into the gravel layer, the first gravel filter layer 14 has water filtration and water seepage characteristics and the good air permeability and water permeability of the permeable geotextile is used to effectively intercept soil particles, fine sand, small stones, etc. while allowing rainwater to pass through effectively. A plurality of first perforated pipes 17 are laid inside the first gravel layer 13. The first perforated pipes 17 have the characteristics of good water collection, drainage, pressure resistance and flexibility. Furthermore, the first perforated pipes 17 are filled with stones or other porous materials to form a larger water storage space. The entire ecological grass planting ditch 2 can reduce the scouring of green land by rainwater, avoid the loss of water and soil, reduce the occurrence of water accumulation, avoid damage to plants, thereby reducing the need for later maintenance of plants, and can also make the terrain vivid and create a diverse ecological environment.

[0022] The upper plant community 9, the middle plant community 10 and the lower plant community 11 are arranged on the ground end of the plant landscape 1. The upper plant community 9 selects 1-3 low-maintenance tree species, and 3 or 5 trees are planted in clusters; the middle plant community 10 is planted with flowering shrubs or small trees with colorful leaves; the lower plant community 11 is planted with low, shade-tolerant, stable landscape effect, and extensively managed ground cover plants, dotted with perennial herbaceous flowering plants, or flower-studded lawns, to enrich the changes in the landscape. By utilizing the different growth spaces of the upper plant community 9, the middle plant community 10 and the lower plant community 11, making full use of sunlight, enhancing the symbiosis between different plant populations, and increasing the ecological diversity of the plant community, the moisture and other nutrients of the soil can be well maintained, thereby reducing the artificial maintenance of plants in the later stage, thereby reducing the consumption of energy resources and reducing the cost of plant landscape construction and maintenance. The plant landscape 1 is provided with a second soil compaction layer 18, a second gravel layer 19, a second gravel filter layer 20 and a second planting layer 21 from bottom to top, and a plurality of second perforated pipes 22 are laid inside the second gravel layer 19. A biological medium filter layer 23 is provided inside the second planting layer 21. The biological filter medium layer is a mixed layer of sandy soil and humus, which meets the growth requirements of plants in the second planting layer 21. The combination of the second planting layer 21 and the biological filter medium layer can reduce the evaporation of soil moisture, maintain soil moisture, increase soil fertility, and reduce the need for artificial water replenishment and fertilization.

[0023] The working principle of this embodiment is as follows: when it rains, on the ecological grass planting ditch 2, rainwater penetrates downward from the pebble layer 16 to the first planting layer 15, the first gravel filter layer 14, the first gravel layer 13 and the first soil compaction layer 12 in sequence. After being in a saturated state, the rainwater that has not yet infiltrated flows into the ecological grass planting ditch 2. After the ecological grass planting ditch 2 reaches a certain overflow water level, it flows into the overflow well 3 through the overflow pipe 4; at the same time, on the plant landscape 1, rainwater irrigates the plant community, and then penetrates downward from the second planting layer 21 to the second gravel filter layer 20, After the second gravel layer 19 and the second rammed earth layer 18 are in a saturated state, rainwater that has not yet infiltrated flows into the ecological grass-planting ditch 2. After the ecological grass-planting ditch 2 reaches a certain overflow water level, it flows into the overflow well 3 through the overflow pipe 4; the water in the overflow well 3 can be transported to the sprinkler branch pipe 7 through the water pipe 6 and the sprinkler main pipe in turn under the action of the submersible pump 5, and then is diverted and transported to the sprinkler branch pipe 7, and is sprayed through the sprinkler head 8, so that the upper plant community 9, the middle plant community 10 and the lower plant community 11 on the ground end of the plant landscape 1 can all be irrigated, and the operation is done in this way.
