Description

Technical Field

[0001] This invention relates to the field of greening bare soil, and particularly to a production process and construction method for a composite functional organic mulch for gardens. Background Technology

[0002] In landscaping maintenance, trees and shrubs need to be pruned regularly according to their growth cycle—heavy pruning during dormancy to adjust the tree shape, and light pruning during the growing season to remove overly long branches, resulting in a large number of branches. In the past, these branches were mostly mixed with household waste for disposal, which not only occupied landfill space but also wasted wood fiber resources. Now, after sorting and removing impurities, they are transformed into the core raw material for producing "Mochi" (organic landscaping mulch) through processes such as crushing and fermentation. This "waste-to-use" model not only solves the problem of branch disposal but also provides a natural woody base for Mochi, which aligns with the concept of circular maintenance.

[0003] However, the existing technology of Mochi has a single function, and its main purpose is to cover the bare surface of tree pits to suppress dust and beautify the landscape, which is difficult to meet the current needs of refined garden maintenance. Summary of the Invention

[0004] This invention provides a production process and construction method for a garden composite functional organic mulch, in order to solve the problems mentioned in the background art.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solution: a production process for a garden composite functional organic mulch, comprising the following steps: After collecting the branches, they are sorted and processed. The processed branches are cut and crushed to obtain pre-treated wood chips; The pretreated wood chips are fermented, decomposed, and sieved to obtain decomposed wood chips; An organic covering is prepared by adding a composite functional agent to decomposed wood chips and then spraying them.

[0006] Preferably, during the sorting process, debris such as metal, stones, plastic, and ropes should be removed from the branches.

[0007] Preferably, when the branches are cut, a chainsaw or a cutting machine is used to cut the collected branches to a length of less than or equal to 1.2m so that their length matches the feed inlet of the crusher.

[0008] Preferably, when the branches are crushed, a high-speed rotating blade of a crusher is used to cut and slice the branches. The rotation speed of the high-speed rotating blade is 1200r / min–1500r / min, and the output is pre-treated wood chips with a length of 5cm-10cm.

[0009] Preferably, the fermentation and composting includes the following steps: The moisture content of the pretreated wood chips is adjusted after they are piled up. Add composting microbial agents to the stockpile; After adding composting agents, the wood chips are turned and cured. When the pretreated wood chips turn dark brown and have no odor, a composting test is conducted to obtain the fully decomposed wood chips.

[0010] Preferably, when stacking the pretreated wood chips, the stack height is 1.2m-1.5m and the stack width is 2m-3m. When adjusting the moisture content, water is added to the stack, and the water addition is stopped after the moisture content in the stack reaches 55%-60%.

[0011] Preferably, the added composting agent is one or a combination of bacteria, fungi, or actinomycetes, and the weight of the composting agent is 0.5-1% of the weight of the stockpile.

[0012] Preferably, the turning and curing is carried out 2-3 times during fermentation, the fermentation time is 15-25 days, and the fermentation temperature is 55℃-65℃.

[0013] Preferably, when preparing the composite functional agent, 0.1% to 0.3% of a water-retaining agent, 0.2% to 0.5% of a herbicide adjuvant, and 0.1% to 0.3% of a biological insect repellent and bacteriostatic agent by weight of the decomposed wood chips are added to the agent tank and mixed and stirred to obtain the composite functional agent. When spraying the decomposed wood chips in the mixer using a spraying device, it is ensured that the composite functional agent is evenly adhered to the surface of the decomposed wood chips, without local lumps or omissions.

[0014] Preferably, a construction method for a garden composite functional organic mulch, applicable to the production process of the garden composite functional organic mulch described above, includes the following steps: The root system of trees is delineated on the ground based on the types and ages of plants in the garden; Lay multiple layers of organic mulch on the ground outside the root zone of the trees; Apply pressure to the top layer of organic mulch and compact all of it.

[0015] The beneficial effects of this invention are as follows: In the solution of the present invention: The purpose of preparing a compound functional agent and spraying it onto organic mulch is to regulate the chemical maintenance function of the organic mulch. That is, after adding the compound functional agent, it can improve the ability of the mulch to retain water and moisture for the roots, inhibit the growth of weeds, and control pests and diseases, thereby achieving the ability to maintain the garden with precision. Attached Figure Description

[0016] Figure 1 This is a process flow diagram of the present invention; Figure 2This is a schematic diagram showing the relative positions of the spraying equipment and the mixer of the present invention.

[0017] The components include: 1. Crusher; 2. Conveyor belt; 3. Mixer; 4. Chemical tank; 5. Spraying equipment. Detailed Implementation

[0018] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0019] Example 1: Reference Figures 1-2 A production process for a multifunctional organic mulch for gardens includes the following steps: After collecting the branches, they are sorted and processed. The processed branches are cut and crushed to obtain pre-treated wood chips; The pretreated wood chips are fermented, decomposed, and sieved to obtain decomposed wood chips; An organic covering is prepared by adding a composite functional agent to decomposed wood chips and then spraying them.

[0020] During the sorting process, debris such as metal, stones, plastic, and ropes must be removed from the branches.

[0021] The principles and beneficial effects of the above scheme are as follows: Fallen and pruned branches are collected from the garden. During sorting, debris such as metal, gravel, plastic, and ropes are removed to prevent damage to the cutting tools when crushing the pre-treated branches. The sorted branches are then cut and crushed to obtain pre-treated wood chips. These pre-treated wood chips are further fermented, decomposed, and sieved to obtain decomposed wood chips. At the same time, a compound functional agent is prepared and sprayed onto the organic mulch. The purpose is to regulate the chemical maintenance function of the organic mulch (Mochi). After adding the compound functional agent, the water-retaining agent is distributed in a gradient, which improves its ability to retain water and moisture for the roots, inhibit the growth of weeds, and control pests and diseases, thereby achieving the ability to achieve refined garden maintenance.

[0022] Example 2: Reference Figures 1-2 When cutting the branches, a chainsaw or a cutting machine is used to cut the collected branches to a length of less than or equal to 1.2m, based on the actual situation, so that its length matches the feed inlet of the crusher 1. This prevents the feed inlet of the crusher 1 from getting stuck when feeding branches into the crusher 1, and also avoids the phenomenon of incomplete crushing of the collected branches during crushing. At the same time, it can avoid secondary crushing of branches and improve the working efficiency of the process.

[0023] Example 3: Reference Figures 1-2When the branches are crushed, the branches are cut and sliced ​​using a high-speed rotating blade of a crusher 1. The rotation speed of the high-speed rotating blade is 1200r / min–1500r / min, and the output is pre-treated wood chips with a length of 5cm–10cm. The process utilizes a rotating cutter head with a rotation speed of 1200r / min–1500r / min, and by adjusting the diameter of the rotating cutter head, the length of the pre-treated wood chips can reach 5cm-10cm when shredding branches of different diameters. The pre-treated wood chips within this size have excellent particle size after decomposition, and the addition of composite functional agents can avoid the phenomenon of poor agent adhesion. This ensures that Mochi has excellent and refined garden maintenance capabilities after being laid on the ground.

[0024] Example 4: Reference Figures 1-2 After the branches are crushed to obtain pretreated wood chips, they are fermented and composted. The fermentation and composting process includes the following steps: After the pre-treated wood chips are piled up, the area occupied by the pre-treated wood chips that need to be decomposed is planned within the site to avoid affecting subsequent process steps and personnel passage. Then the moisture content of the pre-treated wood chips is adjusted. Adding composting agents to the compost mix aims to kill grass seeds, insect eggs, and pathogens, preventing uncomposted particles or live insect eggs and pathogens from affecting subsequent functions, and thus avoiding negative impacts and damage to the garden ecology after laying Mochi. In addition, composting agents can also decompose cellulose, hemicellulose and other difficult-to-degrade organic matter in tree branches through microbial metabolism, converting them into humus that is easily absorbed by plants, while adjusting the carbon-nitrogen ratio to provide a more suitable substrate for the subsequent attachment of functional agents. After adding composting agents and turning the piles for curing, statistical analysis after multiple experiments showed that when the pre-treated wood chips are dark brown and odorless, the composting test is performed to obtain the fully composted wood chips. Therefore, process implementers can directly infer from the appearance and properties of the wood chips whether they have reached complete composting, which greatly improves the efficiency of process implementation.

[0025] Example 5: Reference Figures 1-2When stacking the pretreated wood chips, the optimal stacking height is 1.2m-1.5m and the optimal stacking width is 2m-3m. When adjusting the moisture content, if the moisture content of the pretreated wood chips is too low, water should be added to the stack. Water addition should be stopped when the moisture content of the stack reaches 55%-60%. Through multiple experiments, it has been found that when testing whether the moisture content of the pretreated wood chips is appropriate, i.e. whether it has reached 55%-60%, it can be manually tested by the process implementers. The ideal moisture content is when the chips can be formed into a ball when squeezed in the hand and crumbles easily when released. Simultaneously, if the moisture content of the pretreated wood chips is too high, they need to be placed in a cool and ventilated place to dry before composting and stacking. This can reduce the moisture content of the pretreated wood chips and prevent the growth of other microorganisms in the wood chips.

[0026] Example 6: Reference Figures 1-2 The added composting agent is one or a combination of bacteria, fungi, or actinomycetes. The preferred weight of the composting agent is 0.5-1% of the weight of the compost pile. Suitable composting agents include: bacteria such as Bacillus subtilis and Bacillus licheniformis, which can rapidly decompose easily degradable organic matter such as soluble sugars and proteins in tree branches, initiating the fermentation process; fungi such as Trichoderma, Aspergillus niger, and Aspergillus oryzae, which can secrete cellulase and hemicellulase to decompose cellulose and hemicellulose in tree branches; and actinomycetes such as Streptomyces, which can decompose stubborn organic matter such as lignin and convert it into humus, improving the fertility and stability of the mulch. The advantage of this type of compound agent lies in its synergistic effect: bacteria rapidly initiate fermentation, fungi decompose fiber / hemicellulose, and actinomycetes convert lignin, jointly ensuring that the tree branches are thoroughly decomposed within 15-25 days, while simultaneously killing grass seeds, insect eggs, and pathogens. Different types of composting agents can be mixed based on different garden maintenance needs to achieve a compound maintenance effect.

[0027] Example 7: Reference Figures 1-2 During the fermentation process, specifically the fermentation of pre-treated wood chips under the combined action of water and composting agents, the pre-treated wood chips provide a fermentation platform, the composting agents decompose organic matter, and the water provides fermentation humidity. The fermentation process is repeated 2-3 times, with a total fermentation time of 15-25 days and a fermentation temperature of 55℃-65℃, until the wood chips turn dark brown, are odorless, and have killed weed seeds, insect eggs, and pathogens. The fermentation then achieves the predetermined technical goal. Furthermore, after composting, the wood chips cannot be directly laid out. They must first be naturally cooled. This involves spreading the composted wood chips and allowing them to cool naturally to room temperature (20-25℃) to avoid high temperatures affecting the curing effect of the subsequently added functional agents. A vibrating screen is then used to sieve the chips, removing uncomposted impurities and particles to obtain clean, uniform composted wood chips. After sieving, a further particle size check is performed to ensure the sieved wood chips meet the particle size standards and are free of impurities.

[0028] Example 8: Reference Figures 1-2 When preparing the composite functional agent, 0.1% to 0.3% of water-retaining agent, 0.2% to 0.5% of herbicide, and 0.1% to 0.3% of biological insect repellent and antibacterial agent by weight of the decomposed wood chips are added to the agent tank 4 and mixed and stirred to obtain the composite functional agent. When the decomposed wood chips in the mixer 3 are sprayed with the spraying equipment 5, it is ensured that the composite functional agent is evenly adhered to the surface of the decomposed wood chips without local lumps or omissions. Specifically, the preparation method of the composite functional agent is as follows: first, the agent is stirred in the agent tank 4, and then the agent is sprayed with the spraying equipment 5 connected to the agent tank 4. The agent tank 4 is used to stir the composite functional agent, and the spraying equipment 5 is used to evenly spray the atomized composite functional agent onto the decomposed wood chips. Conveyor belt 2 is used to feed decomposed wood chips into mixer 3. During the feeding process, the decomposed wood chips can be placed directly on conveyor belt 2, or when the decomposed wood chips contain products with unqualified particle size, they can be crushed again by crusher 1 and then transported to mixer 3 by conveyor belt 2. The water-retaining agent enhances the water retention performance of Mochi through atomized spraying by the spraying equipment 5. Potassium polyacrylate water-retaining agent is preferred. On this basis, the water-retaining agent can prevent the rapid evaporation of other components in the compound functional agent and prevent the maintenance effect from quickly losing its effectiveness. The herbicide adjuvant is preferably a plant-derived herbicide or an organic herbicide film adjuvant, which can form a dense covering layer on the surface of Mochi to inhibit weed growth. The biological insect repellent and antibacterial agent is preferably matrine, citronellol, wood vinegar or biological agent, which can effectively repel underground pests and inhibit soil-borne diseases. After spraying the above three materials in the agent pool 4, the agent enters the mixer 3 and is stirred with the decomposed wood chips for no less than 30 minutes to ensure that the composite functional agent sprayed by the spraying equipment 5 is evenly attached to the surface of the Mochi particles, without local lumps or omissions, so that the agent can exert its respective effects to the maximum extent. The addition of water-retaining agents can not only extend the curing time of other chemical components in the compound functional agent on the soil, but also improve the water retention effect of garden grounds when combined with organic mulch.

[0029] Example 9: Reference Figures 1-2 A construction method for a garden composite functional organic mulch, applicable to the production process of any of the above-mentioned garden composite functional organic mulches, includes the following steps: Based on the plant species and tree age in the garden, the root system range of trees is divided on the ground. According to common knowledge, in a given geographical environment, different species of plants and trees of different ages have specific root system characteristics. Furthermore, the approximate range of their root systems can be known. The purpose of dividing the root system range is to lay multiple layers of organic mulch on the ground outside the root system range to avoid the mulch covering the ground where the roots are located, further ensuring the aeration effect of the roots, avoiding direct contact between the mulch and the roots and stems, which would cause root suffocation, rot, and the breeding of pests and diseases, and forming a safe and breathable zone. Apply pressure to the top layer of organic mulch and compact all of it to improve soil water retention. Since the compound functional agent in the organic mulch contains water-retaining agents, it can not only further improve the soil water retention, but also allow the agents in the compacted organic mulch to act on the ground. The effects of the large amount of compound functional agents on the organic mulch can last on the ground in the garden, further increasing the maintenance time of the garden.

[0030] Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for the present invention. Other modifications can be easily made by those skilled in the art. Therefore, without departing from the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
