Description

Technical Field

[0001] The invention relates to the technical field of gardening, in particular to a method for planting and pruning arc-shaped shrubs. Background Art

[0002] In garden landscape construction and urban greening projects, curved shrub shapes are widely used in scenes such as urban road isolation belts, park landscape belts, and residential green belts because of their smooth visual effects and rich spatial layering. However, the existing curved shrub planting and pruning techniques still have many shortcomings.

[0003] On the one hand, traditional shrub planting often ignores the impact of soil conditions on plant growth and fails to effectively improve the soil characteristics of different regions, resulting in slow shrub growth, low survival rates, and uneven shrubs over time. For example, in some areas with poor soil and poor water and fertilizer retention, shrub root systems are poorly developed, making it difficult to create an ideal landscape effect. At the same time, the existing planting layout lacks scientific planning and is mostly arranged based on experience, failing to fully consider the ecological habits and growth needs of shrubs. This also results in uneven lighting and uneven growth of shrubs, making it difficult to maintain the beauty and stability of the curved surface.

[0004] On the other hand, manual pruning of shrubs is inefficient and inaccurate, making it difficult to achieve a smooth curved surface. Furthermore, improper handling of pruned branches and leaves not only wastes resources but can also lead to the growth of pests and diseases. Furthermore, traditional irrigation and fertilization methods lack precise control, wasting water and fertilizer while failing to meet the needs of shrubs at different growth stages, impacting their healthy growth and the durability of their landscape effects.

[0005] Existing shrub planting and pruning techniques fail to effectively combine ecological functions, have limited effects in terms of rainwater interception and ecological diversity enhancement, and cannot fully realize the ecological value of garden plants. Summary of the Invention

[0006] In view of the problems in the prior art, the present invention provides a method for planting and pruning arc-shaped shrubs.

[0007] The technical solution adopted by the present invention to solve the technical problem is: a method for planting and pruning curved shrubs, comprising the following steps: The shrub planting area is determined through soil sampling and testing and topographic mapping. The planting area includes the lawn surface and the shrub surface, and a U-shaped drainage ditch is set between the two. Bioindicators are used to qualitatively evaluate the soil ecological environment of the planting area. Based on the evaluation results, a specific soil improvement plan is customized, which includes the adjustment of the amendment formula and the optimization of the application method.

[0008] As a further technical solution, the soil conditioner is composed of 30-40% humus, 15-22% super absorbent resin, 10-15% composite microbial agent, 8-14% volcanic rock particles, 8-13% peat soil, 5-8% seaweed extract, and 2-2.4% plant growth regulator in percentage by weight; The humus is humic acid from weathered lignite screened through an 80-100 mesh screen, with an organic matter content of ≥65% and a pH of 6.5-7.5; the super absorbent resin is a starch-grafted acrylate copolymer, with a water absorption rate of ≥300 times and a gel strength of ≥2000 Pa; the composite microbial agent is a mixture of phosphate-solubilizing Bacillus megaterium, nitrogen-fixing rhizobium, and potassium-solubilizing Bacillus mucilaginosus in a mass ratio of 2:1:3, with an effective viable count of ≥200 million / g; the plant growth regulator is a rooting agent formed by compounding indolebutyric acid and naphthaleneacetic acid in a ratio of 2:1; The soil conditioner is applied to the shrub planting holes using a layered interval injection method, with each layer applying at a thickness of 10-15 cm.

[0009] As a further technical solution, a permeable layer consisting of gravel with a particle size of 5-10 mm and permeable geotextile is laid at the bottom of the U-shaped ditch. The ditch is connected to the rainwater collection pool through an underground pipe with a one-way valve to realize the collection, filtration and recycling of surface water for irrigation.

[0010] As a further technical solution, the terrain analysis module of the geographic information system (GIS) is used, combined with the light and water requirement data of the shrub varieties, to plan the shrub planting locations and arrange them in order from low to high to form an arc-shaped planting belt with a slope of 3-5°.

[0011] As a further technical solution, based on the growth rate of shrubs and combined with the precipitation and sunshine duration in real-time meteorological data, the pruning cycle and pruning amount of shrubs are dynamically adjusted to achieve a highly smooth transition of the curved surface from one side of the lawn surface to the other.

[0012] As a further technical solution, during the growth process of the shrubs, the edge shaping shrubs are regularly pruned and the shrubs are pruned into a continuous and smooth curved arc according to a preset curvature radius parameter of 0.5-1m.

[0013] As a further technical solution, the branches and leaves produced during the pruning process are crushed to a particle size of less than 1 cm and then evenly spread on the surface of the shrubs to form a covering layer with a thickness of 3-5 cm.

[0014] As a further technical solution, monitoring nodes including soil moisture sensors, light intensity sensors, and air temperature and humidity sensors are deployed at intervals of 5-8m in the planting area to build a wireless sensor network. The monitoring nodes transmit data to the control system in real time, and the control system accurately gives the processing volume of drip irrigation and fertilization based on the feedback data.

[0015] As a further technical solution, the above-mentioned planting and pruning methods can increase the rainwater interception rate in the planting area by 25-35%. At the same time, the arc-shaped layout of shrubs with different heights can be used to form a three-dimensional landscape effect with seasonal changes.

[0016] As a further technical solution, the above-mentioned planting and pruning methods are applied to scenes such as urban road isolation belts, park landscape belts, and residential green belts.

[0017] Beneficial effects of the present invention: The arc-shaped shrub planting and pruning method provided by the present invention achieves a comprehensive improvement in ecological benefits, landscape effects and resource utilization efficiency through multi-dimensional technical design and synergy.

[0018] This soil conditioner, through its scientifically designed components, significantly improves the physical and chemical properties of soil. Humus, derived from 80-100 mesh weathered lignite humic acid, boasts a high organic matter content (≥65%) that improves soil aggregate structure, increases porosity, and enhances water and fertilizer retention. The slightly acidic pH of 6.5-7.5 is ideal for the growth of most shrubs, while ion exchange absorbs heavy metals, reducing the risk of soil contamination. The highly absorbent resin, a starch-grafted acrylate copolymer, features a three-dimensional network structure capable of absorbing over 300 times its own weight in water. It slowly releases moisture during droughts, alleviating water loss caused by curved terrain. A gel strength of ≥2000 Pa ensures the resin's stability in the soil, preventing migration due to gravity. Composite microbial agent: Bacillus megaterium phosphate-solubilizing, Rhizobium nitrogen-fixing, and Bacillus potassium-solubilizing are combined in a 2:1:3 ratio. Through metabolic activities such as nitrogen fixation, phosphorus solubilization, and potassium release, they convert unavailable nutrients in the soil into absorbable forms, improving fertilizer utilization. An effective viable bacterial count of ≥ 200 million / g allows for rapid colonization and formation of a dominant bacterial population, inhibiting the growth of pathogens and enhancing soil biological activity. Volcanic rock particles and peat soil: The porous structure of volcanic rock particles enhances soil aeration while releasing trace elements. Peat soil is rich in organic matter and humic acid, further regulating soil pH and synergizing with humus to create a balanced microbial ecosystem. Seaweed extract and plant growth regulator: Seaweed extract contains active substances such as seaweed polysaccharides and amino acids, which can stimulate root development. A combination of indolebutyric acid and naphthaleneacetic acid induces adventitious root formation, improving the survival rate of transplanted shrubs and shortening the seedling acclimatization period.

[0019] Through layered and interval injection, the amendment forms a gradient distribution in the planting hole: the slow-release nutrients in the bottom layer promote the expansion of deep roots, the middle layer retains water to cope with seasonal drought, and the upper layer of microbial agents accelerates the decomposition of surface organic matter, achieving a three-dimensional improvement effect of "water retention-fertilizer supply-root promotion".

[0020] The structural design of the U-shaped drainage ditch has strong ecological value; the permeable layer (gravel + permeable geotextile): the gaps between the gravel with a particle size of 5-10mm can intercept the sediment in the surface runoff, and the permeable geotextile further filters the tiny particles to achieve preliminary purification of rainwater; the porosity of the permeable layer reaches 40-50%, which can quickly absorb rainwater, reduce the surface runoff velocity of the curved surface, and reduce soil erosion.

[0021] The wireless sensor network (soil moisture, light intensity, air temperature and humidity sensors) collects data in real time at 500ms intervals. After analysis by the control system, it accurately adjusts the drip irrigation amount and fertilizer concentration to avoid soil compaction caused by excessive irrigation, while reducing fertilizer leaching losses by more than 20%.

[0022] Through full-chain technological innovations in soil improvement, rainwater interception, three-dimensional layout, dynamic pruning, and data-driven, this invention has achieved the following core breakthroughs: it can build a sustainable slope ecosystem, with strong landscape effects and low costs. It is suitable for scenarios such as urban road isolation belts and park landscape belts, and has significant promotion and application value. BRIEF DESCRIPTION OF THE DRAWINGS
