Description

Technical Field

[0001] The present application relates to the technical field of plant landscape construction, and in particular to a method for constructing a low-maintenance plant landscape mainly based on perennial herbaceous plants. Background Art

[0002] Plant landscape refers to the colorful and diverse scenery of different plant communities in different forest phases, seasonal phases, and colors composed of a variety of natural or artificially planted trees, shrubs, grasses, ancient and famous trees.

[0003] The plant landscape dominated by herbaceous plants is called flower border in a broad sense. It refers to a flower landscape that simulates the interlaced growth of various wild flowers on the edge of natural woodlands. After artistic design, perennial flowers are planted in strips of garden areas in a mixed patchy manner on the plane and in a staggered manner on the facade.

[0004] Plant landscape construction technology has been developed for a period of time, but many problems still exist due to the inconsistent understanding and requirements of many practitioners on the concept of plant landscape. The most prominent one is the contradiction between the pursuit of immediate effect and long-term appreciation. If the immediate effect is to be achieved, more one- or two-year-old plants are selected, which only bloom in the current season, with a short flowering period and a short viewing period. By increasing the number of plantings, it is generally required to be densely packed without exposing the soil to achieve a better viewing effect.

[0005] In the prior art, in the early design stage of plant landscape construction dominated by herbaceous plants, only visual effects are considered, and the interspecific relationships of different plants, as well as the succession dynamics and ecological management after the community is built are not considered. In addition, in order to meet the design requirements and pursue immediate effects, the plant planting density is very high, with the standard of not exposing the soil. No reasonable plant growth space is reserved, resulting in plants competing for nutrition and living space, causing some plants to grow too vigorously while others grow poorly. The community structure is unreasonable and unstable, and it is impossible to form a natural succession plant community, making it difficult to maintain a long-term ornamental effect. Summary of the invention

[0072] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0073] Embodiment 1

[0074] A low-maintenance landscaping approach that is dominated by perennial herbaceous plants, including:

[0075] S11: Analyze the construction site;

[0076] Analyze the site conditions, habitat factors and surrounding environment of the construction site, including the original vegetation type, site area, topography, soil conditions, drainage conditions, lighting conditions, atmospheric environment, surface water, site flow, traffic environment, surrounding buildings and facilities, etc., to obtain basic site conditions.

[0077] S12: Generate plant landscape design plan according to plant landscape project requirements;

[0078] S13: Select the required plants according to the plant landscape design plan;

[0079] S14: Perform site treatment based on the construction site analysis results;

[0080] S15: planting the selected plants in the treated site;

[0081] Among them, the plant landscape design plan includes: theme design, community structure design, graphic design, facade design, color and texture design and seasonal design;

[0082] Community structure design includes:

[0083] Divide plant communities into ground cover, mosaic, theme, and structural layers;

[0084] According to the function of each layer in the community and combined with the plant CSR ecological strategy, plants with different strategy types are allocated to different layers, and perennial herbaceous plants are the main type of plants.

[0085] It should be noted that the current common plant landscape construction process generally includes: site analysis → scheme design → plant selection → site treatment → plant planting → post-maintenance.

[0086] This technical solution optimizes the design process based on the existing plant landscape construction process. Specifically, the plant landscape design scheme in this technical solution includes: theme design, community structure design, plane design, facade design, color and texture design, and seasonal design.

[0087] Among them, community structure design is of high importance, and community structure design includes:

[0088] Divide plant communities into ground cover, mosaic, theme, and structural layers;

[0089] According to the function of each layer in the community and combined with the plant CSR ecological strategy, plants with different strategy types are assigned to different layers.

[0090] Assign different strategies to different layers, including:

[0091] Allocate stress-tolerant plants to the ground cover layer;

[0092] Mosaic layer distribution of weedy plants;

[0093] Thematic layers were assigned competitive plants, stress-tolerant plants, or weedy plants;

[0094] Competitive plants or stress-tolerant plants are allocated in the structural layer.

[0095] It should be noted that in the present technical solution, when allocating plants of different strategic types to different layers, perennial herbs are the main body. "Perennial plants" refer to plants whose individual lifespan exceeds two years, and these plants include woody plants and certain herbs. Herbaceous plants refer to plants with underdeveloped xylem in the stem, few lignified cells, and weak supporting power. Among the herbaceous plants, the life cycle of perennial herbs is usually more than one year, and they can live for many years or even decades. Their leaves are usually evergreen and can remain green even in the cold winter. The growth rate of perennial herbs is relatively slow, but they can continue to grow and bloom in multiple seasons. Compared with annual and biennial flowers, perennial flowers have a longer growth cycle, stronger adaptability, and easier management, so perennial flowers are commonly used in landscaping.

[0096] In specific practice, according to the specifications, growth characteristics and interspecific relationships of each plant, based on the community ecology stratification theory, the plant community is divided into ground cover layer, mosaic layer, theme layer and structural layer. According to the function of each layer in the community, combined with the plant CSR strategy, plants with different strategy types are selected.

[0097] CSR strategies include: C-type strategy, S-type strategy and R-type strategy, which represent the different adaptation strategies exhibited by plants during their growth process.

[0098] The three dimensions of CSR, C, S, and R, represent the survival strategies of plants in terms of competition, tolerance, and resource acquisition. Competitiveness (C) refers to the ability of plants to compete for limited resources, tolerance (S) refers to the ability of plants to tolerate environmental stress, and resource acquisition (R) refers to the strategy of plants in obtaining and utilizing resources.

[0099] The three strategies of C, S, and R correspond to the characteristics of plants under different environmental conditions. Plants with the C-type strategy usually have a strong sense of competition. They can quickly occupy the growth space and have a high growth rate and reproductive capacity. Plants with the S-type strategy pay more attention to the adaptation and tolerance of the environment. They usually show strong tolerance under harsh environmental conditions. Plants with the R-type strategy pay more attention to the acquisition and utilization of resources and have an advantage in relatively stable and rich environmental conditions.

[0100] Based on this, the structural layer selects C strategy plants or S strategy plants. These plants are usually thick-lined, relatively tough, large in size, and relatively stable in form throughout the year, making them suitable for the structural layer. When constructing the plant landscape, the location of the structural layer plants should be determined first to determine the framework structure of the plant landscape.

[0101] The theme layer selects C strategy plants, S strategy plants or R strategy plants. The theme layer plants are mixed in groups to reflect the volume of the plant landscape.

[0102] The mosaic layer selects R strategy plants. Usually, plants with small size, slender stems or low presence after flowering are selected.

[0103] For the ground cover layer, choose S-strategy plants. Choose plants that are not visually eye-catching, have relatively low-key and soft colors, and are not too strong in form.

[0104] In this technical solution, community structure design is carried out, and the community ecology stratification theory is adopted to divide the low-maintenance plant community into ground cover layer, mosaic layer, theme layer and structural layer. According to the plant community CSR strategy, considering the plant's own specifications and growth characteristics, different types of plants are selected for different levels of the community. The interspecific relationship of plants is made harmonious, the community is stabilized for a long time, and the plant landscape is low-maintenance and long-term ornamental.

[0105] It should be noted that graphic design includes:

[0106] Determine the location of plant groups, and use different forms of plant groups to randomly distribute or repeatedly arrange them to form a dense and sparse community spatial layout;

[0107] Determine the plant positions in the theme layer, structural layer, ground cover layer and mosaic layer in the group in turn;

[0108] Plants that meet the preset crown diameter and stem diameter are scattered in the group interval;

[0109] Among them, the forms of clusters include at least: ribbon shape, semi-enclosed shape, disordered shape and mixed shape.

[0110] In specific practice, the design of plant groups should be carried out first in graphic design. Different forms of groups should be randomly distributed or repeatedly arranged to form a dense and sparse community space layout. Finally, plants with small flowers and slender stems should be planted in the intervals of the groups to increase rhythm and change. It is best to have an odd number of plants such as 3, 5, and 7. If there are more than 9 plants in the group, this principle can be ignored. Plant group design usually has several forms such as ribbon shape, semi-enclosed shape, disordered shape and mixed planting shape. Different forms can be selected according to the structure of the plant landscape community. First, determine the position of the theme plants and structural plants, then determine the ground cover plants, and finally select mosaic plants to set off the main landscape plants.

[0111] It should be noted that the facade design includes:

[0112] The facade design is carried out according to the plant shape and vertical fluctuations, including:

[0113] Identify prospect plants based on their height and resistance;

[0114] Determine mid-ground plants based on seasonal changes and viewing periods;

[0115] Determine the background plants based on color and plant type.

[0116] In actual practice, the plant shape and vertical fluctuations should be considered when designing the facade. For low-maintenance plant landscapes, it is necessary to utilize the forms and contours of different plants under a reasonable community structure to create a more natural, rich and varied facade landscape.

[0117] Plants can be divided into foreground plants, middleground plants, and background plants according to their height. It is advisable to select low-growing and highly resistant perennial plants as the foreground; the middleground is the visual focus, and it is advisable to select perennial flowers and ornamental grasses with rich seasonal changes and long viewing periods; background plants are usually relatively low-key in color to set off the main scenery, and often use evergreen shrubs, cool-colored ornamental grasses, or tall, upright, and beautiful perennial flowers.

[0118] It should be noted that color and texture design includes:

[0119] Color design and texture design;

[0120] Color design requirements include:

[0121] Use cool-colored plants to create a tranquil and cool visual effect and deepen the sense of distance;

[0122] Use warm-colored plants to create a warm and comfortable visual effect and reduce the sense of space;

[0123] Use contrasting colored plants to highlight focal points;

[0124] Use mixed-color plants to create a soft and unified visual effect;

[0125] The requirements for texture design include:

[0126] Use coarse-textured plants as a focal point or structural layer;

[0127] Use delicate plants as a mosaic;

[0128] Use medium-sized plants as a transition between coarse-textured and fine-textured plants;

[0129] Mix several ground cover plants of the same texture as base plants.

[0130] In specific practice, the requirements for color design are: to express a tranquil and cool visual effect and deepen the sense of distance, choose cool-colored plants; to express a warm and comfortable effect and reduce the sense of space, choose warm-colored plants; if you need to highlight the focus, choose contrasting colors with strong visual impact; if you need to achieve a soft and unified effect, choose similar colors; if you need to achieve a rich and varied landscape effect, use mixed colors.

[0131] The requirements for texture design are as follows: Coarse plants usually have thick and loose branches, large and hard leaves, and most of them have uneven leaf edges, thorny and hairy leaves with darker colors. They are used as main scenery or structural plants. Since coarse plants have the psychological feeling of making the scenery tend to the viewer, making the space scale smaller, small spaces need to reduce their use. Delicate plants usually have small leaves, smooth surfaces and bright colors, relatively soft and compact branches, and neat and dense outlines. Visually, because their branches are soft, tight and have clear outlines, they are used as inlays. Medium-sized plants can produce neutral psychological colors and spatial perceptions. As a transformation and transition between coarse and delicate plants, they make the low-maintenance plant landscape unified as a whole and the space changes naturally. When choosing the base plants for low-maintenance plant landscapes, two or three ground cover plants with similar textures are often selected to mix and plant to achieve an overall coordinated, comfortable and harmonious atmosphere.

[0132] It should be noted that seasonal design includes:

[0133] Locate early spring flowering plants, late spring flowering plants, summer flowering plants, and fall flowering plants in that order;

[0134] Determine the location of plants needed for the ornamental gap period in the fall and winter phases.

[0135] In practice, when designing seasonal phases, the location of early spring and late spring flowering plants should be determined first, followed by summer flowering plants, and finally autumn flowering plants. In addition, perennial flowers that bloom in summer and autumn should be planted in front of bulbous flowers to block plants that have poor landscape effects during the seedling removal period.

[0136] We should also pay attention to the landscape construction in autumn and winter. We should appropriately select ornamental grasses, evergreen plants and flowering shrubs as the framework of plant landscape to fill the ornamental gap of the landscape in autumn and winter and stabilize the overall effect of plant landscape.

[0137] It should be noted that before carrying out site treatment based on the construction site analysis results, refer to Figure 2 , the method further comprises:

[0138] S16: Based on the planting density strategy, the planting position of each plant is drawn according to the plant landscape design plan and the selected plants;

[0139] Drawing requirements include:

[0140] The planting density of linear plants is 1 / 4 of their mature height;

[0141] The planting density of spherical clumping plants in the middle range of height is 1 / 2 of its mature height;

[0142] The planting density of flat clumps is equal to their height;

[0143] The planting density of vines is twice their height;

[0144] The planting density of bulbous plants is 8-10cm planting distance.

[0145] In actual practice, AutoCAD software is used to draw construction drawings, and the planting position of each plant is drawn based on the design plan and the results of preliminary plant screening.

[0146] When drawing the construction drawings, the planting density of each type of plant shall be controlled according to the following requirements: the planting density of linear plants is 1 / 4 of their mature height; the planting density of medium-height spherical clumping plants is 1 / 2 of their mature height; the planting density of flat clumping plants is equal to their height; the planting density of vines is twice their height; the planting density of bulbous plants is 8-10cm apart.

[0147] After drawing is completed, the drawings are exported to guide subsequent plant planting.

[0148] It is understandable that reasonable growth space between plants should be reserved when drawing construction drawings, and planting should be carried out strictly according to the drawings during construction to ensure that each plant in the plant landscape has a reasonable growth space, so that the plants can reach a healthy physiological state after growing for a period of time, and the plant community can achieve the best ornamental effect for a period of time after the plant landscape is built and remain stable for a long time.

[0149] It should be noted that, refer to Figure 3 , select the required plants according to the plant landscape design plan, including:

[0150] S131: Obtain the maintenance cost of plants required in the plant landscape design plan;

[0151] S132: Plants with maintenance costs below a preset cost threshold are considered to have passed the screening;

[0152] S133: replacing the plant whose maintenance cost is higher than a preset cost threshold with an alternative plant whose appearance similarity is higher than a preset similarity threshold and whose maintenance cost is lower than the preset cost threshold;

[0153] S134: Generate a list of plants that pass the screening.

[0154] After completing the plant landscape design plan, get a preliminary plant list and then obtain the maintenance cost of the plants required in the plant landscape design plan.

[0155] Preferably, in this technical solution, plants can be classified into low-maintenance levels according to their maintenance costs. Level 1 is highly recommended, level 2 is recommended, and level 3 is not recommended. Plants with level 1 and level 2 evaluation results can be used in the construction of low-maintenance plant landscapes.

[0156] Plants with level one or level two evaluation results can be directly used in subsequent construction. If the evaluation result is level three, the plants are not recommended for use and need to be replaced. Plants with similar appearance conditions should be selected for replacement and low maintenance evaluation should be conducted again until they reach the qualified level. Finally, a list of plants that have passed the screening is generated.

[0157] It is understood that after the design of the scheme is completed, the low maintenance of each plant is evaluated through the low maintenance plant evaluation system, and the appropriate low maintenance plant species are selected. By selecting low maintenance plants suitable for environmental conditions, the long-term survival rate of plant landscape plants is improved, and the low maintenance of plant landscape is achieved from the source.

[0158] It should be noted that site treatment is carried out according to the construction site analysis results, including:

[0159] Soil improvement: If the soil conditions of the construction site are not good, soil improvement must be carried out first. Organic fertilizer and sand can be applied to clay soil; humus organic fertilizer can be applied to gravel soil; lime can be spread on acidic soil; if the surface soil is severely damaged and there are a lot of construction waste and stones in the green space, the foreign soil can be directly replaced; saline-alkali soil can be applied with saline-alkali soil improvement fertilizer.

[0160] Terrain construction: Chengdu has a large amount of rainfall in summer, and terrain construction needs to consider drainage needs. Shallow ditch drainage is used for drainage. At the beginning of the design, the terrain and drainage direction of the construction site should be considered. Generally, the length of the drainage ditch should at least be enough to guide the accumulated water to a place away from the plant landscape to avoid the backflow of accumulated water. The width of the drainage ditch should be determined according to the drainage volume, generally 20-30 cm wide and 10-45 cm deep. The slope of the drainage ditch should be determined according to the drainage volume and the flow rate of accumulated water, generally 1%-3%. Stones can be laid at the bottom to reduce the runoff flow rate. The drainage ditch is linearly laid, and can also be in the form of straight lines, broken lines, winding curves, etc. according to the land conditions and design requirements. At the same time, sponge facilities can be combined to make full use of the terrain for rainwater collection, which can be used for plant irrigation during water shortage periods.

[0161] It should be noted that the selected plants are planted in the treated site, specifically including:

[0162] Determine the variety, specification and quantity of seedlings according to the design requirements, and strictly select seedlings that are strong, free of pests and diseases, full in plant shape, well-developed root system, many fibrous roots and free of mechanical damage. Planters should have a comprehensive understanding of the design drawings and requirements, and carefully check the actual situation on site with the design drawings.

[0163] Before planting, prepare the soil thoroughly according to local conditions.

[0164] Plant plants at designated locations strictly in accordance with the construction drawings.

[0165] When planting, plant larger plants first, and then plant perennials from high to low. For island-style and two-sided low-maintenance plant landscapes, plant from the center to the surrounding areas to avoid affecting the planting effect of surrounding plants.

[0166] After planting, the material is used to pave the surface, and then water it. If the soil sinks after watering, it needs to be filled in time. In hot seasons, the plants need to be properly shaded and sprayed with water to cool down.

[0167] It should be noted that the method also includes: post-care of plants in the plant landscape;

[0168] Specifically include:

[0169] Watering: Water once every 5-7 days during the hot and rainy period in summer, and replenish water in time in the other three seasons according to soil moisture and weather conditions.

[0170] Fertilization: For poor soil, base fertilizer should be applied once when improving. No fertilizer is needed after the overall structure of the construction community is stable. Topdressing can be carried out 3 months after the completion of landscape construction. Usually, compound fertilizer with a reasonable ratio of nitrogen, phosphorus and potassium is selected. If conditions permit, formula fertilizer can be applied according to soil conditions.

[0171] Spraying: After construction is completed, carry out a comprehensive spraying and root irrigation, and then carry out preventive spraying at the end of each quarter.

[0172] Pruning: Prune three times a year: in late spring, clean up the remaining flowers after the flowering period to promote secondary flowering; in late summer, prune plants with excessive branch and leaf growth; in late autumn, clean up the above-ground parts of seedling-killing plants.

[0173] Elimination and replacement: Replace poorly growing and dead plants quarterly, and eliminate aggressive and weak plants every six months.

[0174] In summary, in this technical scheme, community structure design was carried out during the preliminary scheme design. Through the community stratification theory, different types of plants were selected in a targeted manner, which improved the stability and ecology of the plant community in the plant landscape and made the viewing of the plant landscape more lasting.

[0175] The low-maintenance evaluation and screening of plants were carried out, and the most suitable plant species were obtained, which is conducive to the long-term low-maintenance of plant landscapes.

[0176] The plant planting density is controlled when the construction drawings are drawn, and the plants are planted according to the drawings in the later stage, which reserves the growth space of the plants, is conducive to the healthy growth of the plants, and achieves low maintenance of the plant landscape.
