Description

Technical Field

[0001] This invention relates to the field of landscape engineering technology, specifically to a transplanting process for planting and cultivating green seedlings in landscaping. Background Technology

[0002] Landscape greening is an important component of modern urban construction and ecological restoration. In landscape engineering, large tree transplantation, as a common technique for quickly achieving greening effects and optimizing plant configuration, has been widely applied. Its core objective is to safely and efficiently relocate seedlings of a certain size from their native habitat to a new planting location, ensuring they can quickly adapt to the new environment and resume normal growth.

[0003] Existing garden seedling transplanting techniques typically follow a relatively fixed operating procedure: First, the seedling to be transplanted is manually or mechanically dug around using tools such as shovels and hoes to cut the root system and form a soil ball of a predetermined size; then, the soil ball is wrapped with materials such as straw ropes and burlap to prevent it from breaking apart during hoisting and transportation; finally, the wrapped seedling is hoisted and transported to its destination for planting.

[0004] However, this traditional transplanting technique has inherent and insurmountable flaws in practice. Its core operation involves the forced and destructive severing of the root system, inevitably causing severe damage to most of the seedling's absorbing roots, fundamentally weakening the seedling's physiological functions. More seriously, the connection between the damaged roots and the soil becomes extremely fragile, significantly compromising the structural integrity of the root ball. This makes it highly susceptible to disintegration and cracking during subsequent lifting and transportation, causing secondary damage to the surviving roots. Traditional wrapping methods such as binding with straw ropes provide only limited physical support and are largely ineffective in maintaining the moisture balance within the root ball, buffering drastic temperature changes, or protecting the rhizosphere microbial environment. Therefore, after undergoing this series of crude operations, the seedling's root system is not only physically severely damaged but also biologically forcibly separated from its stable and familiar native microenvironment, directly exposing it to a completely new and stressful environment. This directly leads to long-standing technical problems plaguing the industry, such as low transplant survival rates and excessively long recovery periods. In summary, existing technologies employ a passive "destruct first, remedy later" approach, and their technological bottleneck lies in their inability to provide continuous and proactive physiological and environmental support to the root system throughout the entire transplantation process. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a transplanting process that can overcome the defects of existing garden seedling transplanting technology, such as low transplant survival rate and long recovery period caused by severe root damage and sudden changes in rhizosphere environment.

[0006] To solve the above-mentioned technical problems, the first aspect of the present invention provides a transplanting process for planting and cultivating green seedlings in landscaping, the process comprising the following steps:

[0007] a. Construct a functional gel layer in situ around the root system of the seedling to be transplanted, the functional gel layer wrapping the predetermined soil ball;

[0008] b. On the outside of the functional gel layer, a protective shell is constructed in situ, and the protective shell and the functional gel layer together form an ecological root zone capsule;

[0009] c. The seedlings encased in the ecological root zone capsules are excavated and planted as a whole.

[0010] This invention transforms the traditional "digging-wrapping" model into an "in-situ construction-holistic migration" model through a novel technological approach. Before disturbing the seedling root system, an ecological root zone capsule integrating physical protection, water supply, slow nutrient release, and microbial environmental support is pre-constructed. This capsule provides a stable and continuous microenvironment for the root system, actively supporting and protecting it throughout the transplanting process. This fundamentally alleviates the stress response caused by transplantation and enhances the seedling's adaptability and growth performance after transplantation.

[0011] As a preferred technical solution, a root physiological induction step may be included before step a. Specifically, a minimally invasive impact treatment is performed on the boundary soil of the predetermined root ball using high-pressure airflow or high-pressure water flow. This non-contact or micro-contact physical stimulation method aims to gently sever a small number of peripheral taproots to induce the seedling to grow a denser and more vigorous secondary root system inside the predetermined root ball, thereby forming a more stable and more absorbent root mass before transplanting.

[0012] As a preferred technical solution, the functional gel layer is prepared from a specific slurry, which contains the following core components: a polymeric water-retaining agent matrix, a composite microbial agent, and a biostimulant and slow-release nutrient complex. The polymeric water-retaining agent matrix can absorb and lock in a large amount of water, providing a long-lasting water source for the roots; the composite microbial agent, for example, may contain at least one of mycorrhizal fungi, nitrogen-fixing bacteria, phosphate-solubilizing bacteria, and potassium-solubilizing bacteria, which can migrate beneficial microbial communities along with the roots, ensuring the continuity of the rhizosphere microecology; the biostimulant and slow-release nutrient complex provides a continuous and gentle nutrient supply to the roots.

[0013] As a preferred technical solution, the protective shell is formed by in-situ curing of a biodegradable polymer material. This on-site molding method ensures that the protective shell can perfectly fit the irregular surface of the soil ball, forming a seamless and uniform structure.

[0014] Furthermore, to endow the ecological root zone capsule with intelligent interaction capabilities with the external environment, an environmental response regulation unit is preferably incorporated into the biodegradable polymer material. This unit enables the microporous structure of the protective shell to dynamically adjust according to changes in temperature and humidity in the external environment. For example, when the external soil is dry, the micropores of the protective shell shrink, reducing internal moisture evaporation; when the external soil is moist, the micropores expand, enhancing gas exchange, thereby dynamically maintaining an ideal water-air balance environment for the roots. In one specific embodiment, the environmental response regulation unit can be a temperature and humidity sensitive hydrogel microsphere.

[0015] In the specific implementation process, to make the process more scientific and repeatable, the predetermined soil ball has a radius R. t It can be determined using the following formula:

[0016] R t =k s ·D bh

[0017] Among them, D bh k is the diameter at breast height (DBH) of the seedling. s It is a dimensionless coefficient determined based on the root system characteristics of the seedling species (such as deep root, shallow root, etc.).

[0018] Similarly, the application volume V of the functional gel layer g Alternatively, an estimate can be made using the following formula to ensure effective packaging:

[0019] V g =(2πR) t H t )·T g

[0020] Among them, R t H is the radius of the predetermined soil ball. t T is the design depth of the predetermined soil ball. g The designed thickness of the functional gel layer.

[0021] In the process of this invention, the ecological root zone capsule does not need to be removed during the planting operation in step c. As a whole, it functions as a biodegradable unit and will eventually degrade naturally in the soil. The degradation products can also improve the soil, achieving a seamless transition from transplant protection to long-term ecological support, simplifying the operation, and being environmentally friendly.

[0022] This invention provides a transplanting process for cultivating and planting landscaping seedlings. It has the following beneficial effects:

[0023] 1. This invention, by performing root physiological induction before excavation, actively optimizes root distribution using minimally invasive fluid impact, and combines this with a robust protective shell to achieve complete encapsulation of the root ball. This fundamentally avoids the physical damage to the root system caused by rough excavation and bumpy transportation in traditional transplanting methods. This ensures that the integrity and physiological activity of the core absorbing roots are preserved to the maximum extent during transplantation, laying a solid internal foundation for rapid survival after transplantation.

[0024] 2. This invention creates an integrated and long-lasting microenvironment for the root system of transplanted seedlings by constructing a functional gel layer containing a polymeric water-retaining agent, a compound microbial agent, and slow-release nutrients. This gel layer acts like a "nutrient supply station" closely attached to the roots, actively and continuously providing moisture, nutrients, and beneficial bacteria during the most critical recovery period after transplantation. This effectively alleviates transplant stress, shortens the recovery period, and achieves a shift from passive adaptation to active support.

[0025] 3. The environmentally responsive protective shell constructed in this invention, by introducing temperature and humidity-sensitive hydrogel microspheres, endows the transplanting unit with unprecedented intelligent environmental adaptability. This protective shell can automatically adjust the permeability of its microporous structure according to changes in the moisture content of the external soil, ensuring root respiration when moist and reducing water loss when dry. This dynamic self-regulating mechanism provides the root system with a stable buffer layer free from drastic environmental fluctuations, significantly improving the seedlings' adaptability to new environments.

[0026] 4. This invention integrates multiple discrete and cumbersome operational steps in traditional transplantation into a standardized "in-situ construction-overall migration" process. The construction of the ecological root zone capsule transforms the originally fragile soil ball into a solid and well-organized working unit, greatly simplifying the difficulty and risk of hoisting and transportation. It eliminates the need for traditional auxiliary materials such as straw ropes and burlap, significantly improving the efficiency and safety of transplantation operations.

[0027] 5. All materials constituting the ecological rhizosphere capsule in this invention are biodegradable, achieving environmental friendliness in transplant support measures. After fulfilling its initial protective and supportive mission, the entire capsule will gradually decompose in the soil, eventually becoming fully integrated into the ecosystem. Its degradation products can also serve as organic matter to improve the rhizosphere soil. This not only avoids the waste pollution that may be caused by traditional methods, but also achieves a seamless transition from temporary protection to long-term ecological improvement.

[0028] Figure 1 This is a schematic diagram of the method flow of the present invention. Detailed Implementation

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] See attached document Figure 1 , Figure 1 This is a schematic flowchart of a transplantation process according to an embodiment of the present invention. The present invention provides a transplantation process for planting and cultivating green seedlings in landscaping. Its core lies in constructing a multifunctional ecological root zone capsule in situ for the seedling's root system before transplantation through a series of orderly and coordinated steps, thereby significantly improving the success rate and efficiency of transplantation.

[0031] The transplantation process system may include the following core functional modules: a transplantation parameter determination module A, a root physiological induction module B, a functional gel layer construction module C, and an environmentally responsive protective shell construction module D.

[0032] In this embodiment, the initial step of the process is executed by the transplantation parameter determination module A. First, a suitable seedling to be transplanted needs to be selected. The seedling should be in good growth condition, have an attractive shape, and show no obvious signs of disease or pests.

[0033] After selecting the seedlings, the crucial step of quantifying and calibrating transplantation parameters begins. The purpose of this step is to define the precise physical boundaries for the subsequent construction of the ecological root zone capsule. The primary parameter to be determined is the radius of the intended root ball, i.e., the radius R of the transplanted root ball. t The calculation of this radius is not an arbitrary estimate, but rather based on scientific quantitative relationships, and its determination follows the formula below:

[0034] R t =k s ·D bh

[0035] In this formula, the symbol D bh The diameter at breast height (DBH) of the seedling to be transplanted is the trunk diameter measured at a specific height (e.g., 1.3 meters) above the ground. It is one of the most intuitive indicators for measuring the size of the seedling.

[0036] symbol k s This represents a key, dimensionless coefficient representing the root system characteristics of a tree species. This coefficient, derived by those skilled in the art based on long-term practical experience and botanical knowledge, quantifies the intrinsic biological characteristics of different tree species. For example, for shallow-rooted tree species with strong lateral root expansion capabilities (such as willows and poplars), k... sThe value of k will be relatively large; while for deep-rooted tree species with well-developed taproots and concentrated longitudinal root distribution (such as pine and oak), k s The value of will be relatively small. By introducing this coefficient, the determination of the transplantation range is no longer purely based on experience, but is more scientific and targeted.

[0037] The accurate R is calculated using the above formula. t After setting the value, take the center of the sapling trunk as the center and R as the radius. t Using lime powder or other conspicuous markings, draw a complete circle on the ground with radius R. This circle will serve as the physical boundary for all subsequent in-situ construction operations. Simultaneously, based on the type of seedling and R... t The size of the root ball determines the design depth H of a matching transplanted soil ball. t These precise geometric parameters constitute the final output of transplantation parameter determination module A, and serve as input information to guide the precise operations of subsequent root physiological induction module B and other modules.

[0038] After the transplanting parameter determination module A completes its work, the process flow enters the critical step executed by the root physiological induction module B. The core purpose of this step is not direct excavation, but rather to proactively and proactively optimize the root system while maintaining the seedling's in-situ growth, creating optimal internal physiological conditions for subsequent transplantation.

[0039] In this embodiment, the execution of the root physiological induction module B relies on a specially designed annular array high-pressure air or water flow cutting device. The main structure of this device is an adjustable diameter annular frame, on which multiple probes capable of penetrating deep into the soil are evenly distributed. Each probe is connected to a high-pressure fluid generation system, which can eject high-pressure air or water flow from the nozzle at the end of the probe with precisely controlled pressure and flow rate.

[0040] The operation is rigorous and orderly. First, the device is precisely aligned with the circular boundary line marked by the transplanting parameter determination module A, and the probe is driven to vertically insert into the soil to the preset depth. Then, the treatment is not performed all at once around the entire circumference, but follows a strategy of dividing the process into regions and time periods. For example, the entire circumference can be divided into four quadrants. High-pressure fluid jetting is first initiated on the probe in the first quadrant, continuing for a predetermined period. After treating one region, the next region is not immediately moved on; instead, several days or even more than a week are allowed to give the seedlings sufficient time for physiological response before the same treatment is applied to the second, third, and fourth quadrants in sequence.

[0041] Unlike the sharp physical cutting of traditional tools like shovels or hoes, the force generated by high-pressure fluid in the soil is a unique micro-invasive impact. It loosens the soil structure by creating instantaneous high pressure and cavitation effects within the soil, selectively severing some of the larger, more brittle taproots or lateral roots. Simultaneously, numerous more flexible fibrous roots, crucial for water and nutrient absorption, are deflected and bypassed by the fluid's impact, thus being preserved to the greatest extent possible.

[0042] More importantly, this mild and localized root stress essentially sends a strong physiological induction signal to the seedlings. It simulates the growth response of roots when encountering obstacles in the natural environment, stimulating the seedlings' internal hormonal regulatory mechanisms, such as promoting auxin accumulation near the stimulated area. This greatly promotes the sprouting of numerous new secondary roots with extremely high absorption activity within the predetermined root ball area.

[0043] Therefore, after the complete treatment cycle of root physiological induction module B, the root system within the predetermined soil ball is no longer in its original loose distribution state, but has been successfully reshaped into a compact, densely rooted, and highly absorbent independent root ball unit. This not only provides a stable physical basis for the subsequent construction of ecological root capsules, but also fundamentally lays a solid internal guarantee for seedlings to safely overcome transplant stress and quickly adapt to the new environment from a biological perspective.

[0044] After the root physiological induction module B completes its treatment cycle, the process seamlessly transitions to the steps performed by the functional gel layer construction module C. This stage marks the formal beginning of the physical construction of the ecological root domain capsule, whose task is to construct, in situ, an inner support and nourishing system with multiple biological activities around the optimized root mass.

[0045] In this embodiment, the module first needs to formulate a special functional gel slurry. This slurry is not a simple mixture, but a carefully designed composite system containing multiple synergistic components. One of its core components is a polymeric water-retaining agent matrix, such as cross-linked potassium polyacrylate or naturally derived modified sodium carboxymethyl cellulose. These materials have excellent water absorption and retention properties, enabling them to form a stable "micro-reservoir" within the gel layer, continuously providing the necessary moisture to the roots after transplanting.

[0046] Another key component of the slurry is a compound microbial inoculant. To ensure the continuity of the rhizosphere micro-ecosystem, microbial species with high symbiotic specificity with the target tree species are selected. These may include arbuscular mycorrhizal fungi, nitrogen-fixing free-living nitrogen-fixing bacteria, and beneficial microorganisms such as Bacillus megaterium, which can decompose phosphorus and potassium fixed in the soil. These microorganisms are added in the form of highly active freeze-dried powder or fermentation broth to ensure rapid colonization and reproduction upon contact with the root system.

[0047] In addition, the slurry contains a complex of biostimulants and slow-release nutrients. The biostimulants can be natural seaweed extracts or humic acid, used to promote root physiological activity. The slow-release nutrients are encapsulated using microencapsulation technology, encapsulating macroelements such as nitrogen, phosphorus, and potassium, along with various microelements, allowing them to be slowly released within the gel layer at a predetermined rate. This satisfies the nutritional needs of seedlings during their recovery period while preventing root burn caused by excessive nutrient concentration.

[0048] After the slurry preparation is completed, the in-situ construction phase begins. To ensure accurate application, the application volume V of the functional gel layer is... g The estimation is performed using the following formula:

[0049] V g =(2πR) t H t )·T g

[0050] In this formula, R t With H t These represent the radius and design depth of the transplanted soil ball, determined by module A, which specifies the transplanting parameters. The symbol T g This represents the design thickness of the functional gel layer, which is an engineering parameter determined comprehensively based on seedling specifications and soil conditions. It aims to ensure that the gel layer can form an effective functional layer without wasting materials.

[0051] In practice, firstly, a trench is manually excavated along the circular boundary line to the designed depth H. t A fairly narrow trench was then constructed. Subsequently, using a portable slurry mixing and spraying system, the prepared functional gel slurry was evenly sprayed onto the sidewalls of the root ball or directly poured into the excavated trench. The viscosity of the slurry was adjusted to allow it to seep evenly under its own weight and adhere tightly to and coat the entire side surface of the intended root ball, ultimately forming a seamless, complete, and moisture-, nutrient-rich, and beneficial microbial-rich functional gel layer. This layer provides an ideal substrate for the outer protective shell to be constructed and constitutes the active core of the ecological root zone capsule.

[0052] After the functional gel layer construction module C completes its work, the environmentally responsive protective shell construction module D initiates the next stage of the process. This step is the core embodiment of the physical protection and intelligent regulation functions of this invention. Its goal is to directly generate a robust and environmentally responsive protective shell on the outside of the bioactive gel layer through in-situ chemical reactions.

[0053] In this embodiment, the protective shell is made of a specially designed multi-component composite material. Its formulation is designed with strict mass fraction control to ensure the performance of the final product. This relationship can be expressed by the following formula:

[0054] w p +w m +w a =1

[0055] Among them, w p w represents the mass fraction of the structural polymer in the dry weight of the composite material. m The mass fraction of the environmental response control unit in dry weight; while w a This represents the total mass fraction of the catalytic or cross-linking system and other necessary additives in the dry weight.

[0056] The structural polymer is fundamental to the mechanical strength of the protective shell. In this embodiment, a biodegradable polymer composed of modified lignin and polylactic acid can be selected. This combination not only ensures the biodegradability of the shell but also provides the rigidity and toughness necessary for transplantation and transportation.

[0057] The core technology of this step lies in the introduction of a component that serves as an environmental response regulation unit. Specifically, this unit is a specially prepared temperature and humidity-sensitive hydrogel microsphere. For example, a copolymer with N-isopropylacrylamide as the main monomer can be used to prepare microspheres with uniform particle size through emulsion polymerization. These microspheres are uniformly dispersed in the structural polymer component.

[0058] The working mechanism of this control unit utilizes the phase transition properties of specific polymer materials under different temperature and humidity conditions. After transplanting, when the external soil environment is moist (such as after watering or rainfall), these hydrogel microspheres absorb a large amount of water and swell, significantly increasing their volume. Macroscopically, this microscopic volume expansion expands the polymer chains, increasing the pore size of the entire protective shell and improving its permeability, ensuring sufficient root respiration. Conversely, when the external soil becomes dry, the microspheres shrink due to water loss, reducing their volume and causing the microporous structure of the protective shell to tend to close, decreasing permeability and effectively reducing the evaporation and loss of water stored in the internal functional gel layer into the dry soil.

[0059] In the specific in-situ construction operation, a two-component spraying device is used. The mixture of structural polymer and hydrogel microspheres is the A component, while the catalytic or crosslinking system is the B component, both stored in different tanks of the device. During operation, the two components are precisely mixed in a preset ratio in the mixing chamber of the spray gun and then atomized under high pressure, uniformly sprayed onto the surface of the functional gel layer.

[0060] Upon contact with the gel layer surface, the mixed materials undergo a rapid in-situ curing reaction. Within a short time, the liquid sprayed material transforms into a seamless, robust, and intelligently microporous hard protective shell. Thus, a complete ecological root zone capsule is constructed, consisting of an inner active nourishing layer and an outer intelligent protective shell, fully preparing for subsequent overall migration.

[0061] Once the environmentally responsive protective shell construction module D has completed in-situ solidification, a structurally complete and functionally integrated ecological root zone capsule has been constructed. The process of this invention then proceeds to the final stage of overall excavation, migration, and integrated colonization.

[0062] In this embodiment, excavation is carried out outside the solidified protective shell. Because the entire predetermined soil ball is encased in a robust, uniform shell, the traditional risks of soil ball breakage and disintegration due to excavation vibration or insufficient soil cohesion are fundamentally eliminated. The protective shell integrates the originally loose soil and root system into a standard unit with predetermined mechanical strength, greatly improving the operational tolerance.

[0063] The advantages of this invention are further demonstrated during the hoisting and transportation stages. Operators can directly secure the hoisting slings to the shell of the ecological root zone capsule for lifting. This robust shell evenly distributes the hoisting stress, preventing stress concentration and damage to the root system. The stability of the entire seedling unit during transportation is also significantly enhanced, eliminating the need for additional and cumbersome external physical reinforcement measures such as straw ropes, burlap, or wooden boxes.

[0064] Once the seedlings with the ecological root zone capsules arrive at the new planting site, the planting process is also greatly simplified. Operators simply place the entire capsule unit directly into the pre-dug planting hole, followed by standard backfilling and watering procedures. Crucially, the ecological root zone capsules must not be removed or damaged in any way.

[0065] This integrated planting method is one of the key features that distinguishes this invention from all traditional transplanting methods. It ensures that the seedling root system remains enclosed in a stable, undisturbed microenvironment full of supportive materials throughout the entire migration process from the nursery to the new site.

[0066] After transplanting, the ecological root zone capsules begin to work synergistically with the new soil environment over a long period. In the initial stage, the functional gel layer acts as a "miniature reservoir" and "nutrient pack," providing the roots with the most direct supply of water and nutrients, while the environmentally responsive protective shell acts as an intelligent regulator, dynamically balancing the water retention and gas exchange in the rhizosphere. Together, they create an extremely smooth transition period for the seedlings, effectively alleviating the occurrence of "transplant shock."

[0067] Over time, the compound microbial agent within the capsule begins to colonize and multiply in the new soil, establishing a symbiotic relationship with the root system and expanding the seedlings' nutrient absorption range. Simultaneously, the entire ecological root zone capsule, including its protective shell and gel matrix, is composed of biodegradable materials. These materials gradually decompose according to a preset degradation rate under the action of soil microorganisms, eventually fully integrating into the soil. Their degradation products, such as organic matter formed from polymer decomposition, further improve the soil structure and fertility of the planting hole, achieving a seamless transition and functional continuity from initial physical protection after transplanting to later ecological improvement.

[0068] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
