Description

Technical Field

[0001] This invention relates to the field of household lawn planting technology, specifically to a chemical-free, environmentally friendly, and mildew-resistant indoor lawn planting method. Background Technology

[0002] With the acceleration of urbanization and the improvement of residents' quality of life, indoor lawn cultivation is gradually becoming a new demand for beautifying the living environment and creating a natural atmosphere. However, the special nature of the enclosed indoor environment and the high frequency of contact between young children and pets in the home setting have brought multiple technical bottlenecks to traditional lawn cultivation techniques.

[0003] In current technologies, lawn planting generally relies on chemical pesticides (such as carbendazim) to inhibit mold growth and chemical fertilizers (such as urea) to promote growth. These substances easily remain in the indoor environment, posing potential harm to the respiratory system and skin of young children and pets, and do not meet the requirements for healthy and environmentally friendly indoor planting. Some anti-mold technologies use garlic, onion extracts, or herb waste that is toxic to pets as substrates or antibacterial ingredients. While these can reduce chemical pollution to some extent, they may cause adverse reactions such as vomiting and allergies in pets, making them unsuitable for home settings. Insufficient indoor lighting and limited ventilation can easily lead to weakened photosynthesis in lawns and high substrate moisture, which in turn breeds mold and pathogens, affecting lawn survival and indoor air quality. At the same time, urine and feces left on the lawn by pets not only easily breed pathogens such as E. coli and Salmonella, but also release irritating odors such as ammonia. Traditional planting substrates lack the ability to efficiently decompose such excrement, requiring frequent manual cleaning, resulting in high maintenance costs and limited effectiveness. In addition, existing technologies cannot simultaneously achieve rapid lawn establishment, trampling resistance, and environmental adaptability. Ordinary lawns are prone to problems such as leaf yellowing and poor root development under indoor low light and low ventilation conditions.

[0004] Therefore, a non-agricultural and environmentally friendly anti-mold indoor lawn planting method is proposed, which simultaneously solves the problems of mold prevention, pathogen inhibition, pet excrement decomposition, odor elimination and healthy growth of indoor lawns, thus filling the gap in the application of existing technologies in home scenarios. Summary of the Invention

[0005] Technical problems to be solved

[0019] Beneficial effects

[0020] Compared with existing technologies, this invention provides a chemical-free and environmentally friendly method for indoor planting of mold-resistant household lawns, which has the following beneficial effects:

[0021] 1. This solution completely eliminates chemical pesticides, fertilizers, and ingredients harmful to pets (such as garlic and onion extracts or toxic herb waste). It uses harmless compound microbial strains (Bacillus licheniformis, Trichoderma harzianum, etc.), natural plant substrates (peat, coconut coir, etc.), and fermentation raw materials (chrysanthemum, dandelion) throughout the process, thereby eliminating the health risks (such as pet allergies and harm to children) and the toxicity of harmful plant ingredients caused by chemical residues in traditional technologies from the root.

[0022] 2. In this solution, the synergistic effect of Trichoderma harzianum, Bacillus licheniformis and other fungi inhibits the growth of mold hyphae and dissolves the cell walls of pathogens from the source. It is more effective and leaves no residue than traditional chemical antifungal agents. Combined with precise control of temperature and humidity, it solves the technical problem of easy mold growth in indoor closed environments and overcomes the limitations of existing technologies that rely on chemical agents.

[0023] 3. In this solution, Bacillus subtilis and Bacillus mucilaginosus work together to decompose organic matter in pet urine and feces, while Bacillus coagulans adsorbs harmful gases such as ammonia, thus completely solving the problem of pathogenic bacteria growth and odor caused by pet excrement residue; the multi-functional environmental purification spray further enhances the odor decomposition and antibacterial effects, solving the core problems caused by pet activities.

[0024] 4. In this solution, the compound microbial strains promote nitrogen fixation, phosphorus solubilization, and potassium solubilization in the lawn, accelerating lawn establishment, while Bacillus laterosporus and other bacteria promote root development and improve the lawn's resistance to trampling; the three-in-one maintenance spray integrates insect repellent, bactericidal, and fertilizing functions, simplifying the maintenance process; the environmental purification spray can decompose chemical residues in newly renovated houses, expanding the environmental purification added value of lawn planting.

[0025] 5. In this solution, the synergistic effect of photosynthetic bacteria and Streptomyces rubrum and Streptomyces rubrum promotes chlorophyll synthesis and organic matter conversion, and can maintain the healthy growth of lawns even under low light conditions. This solves the technical bottleneck of yellowing and stunted growth of traditional lawns under low light conditions and expands the applicability of indoor planting scenarios. Attached Figure Description

[0026] Figure 1 This is a schematic diagram of the method flow of the present invention. Detailed Implementation

[0027] The technical solutions of 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.

[0028] Please see Figure 1This invention proposes a chemical-free, environmentally friendly, and mildew-resistant method for indoor planting of household lawns, comprising the following steps:

[0029] 1. Preparation of planting substrate

[0030] The planting substrate is composed of harmless substrate materials and compound functional microbial strains. The harmless substrate materials include peat moss, coconut coir, perlite, well-rotted straw, and well-rotted sawdust, avoiding the use of ingredients harmful to pets. The compound functional microbial strains work synergistically to prevent mold, inhibit bacteria, decompose excrement, eliminate odors, and promote growth. The specific formula (by weight) is: 30-40 parts peat moss, 20-30 parts coconut coir, 15-20 parts perlite, 10-15 parts well-rotted straw, and 5-10 parts well-rotted sawdust. After mixing, add 0.2-0.5 wt% Bacillus licheniformis, 0.1-0.3 wt% Trichoderma harzianum, 0.3-0.6 wt% Bacillus subtilis, 0.2-0.4 wt% photosynthetic bacteria, and 0.1-0.2 wt% Bacillus coagulans, and stir thoroughly.

[0031] Bacillus licheniformis and Trichoderma harzianum can inhibit the growth of pathogenic fungi such as molds and kill pathogens in the substrate (affecting plants, people and pets);

[0032] Bacillus subtilis can decompose pet urine and feces, enhancing the stress resistance of lawns;

[0033] Photosynthetic bacteria can promote photosynthesis in lawns when there is insufficient light.

[0034] Bacillus coagulans adsorbs odors from the matrix.

[0035] 2. Grass Seed Selection and Sowing

[0036] Choose shade-tolerant grass species that are harmless to pets (such as perennial ryegrass and tall fescue), which are adaptable, fast-growing, and non-toxic. The sowing rate should be controlled at 15–20 g / m². 2 After sowing, cover with a 0.3-0.5cm thick planting substrate to avoid exposing the grass seeds.

[0037] 3. Planting environment control

[0038] The indoor temperature should be controlled between 15-25℃, which is suitable for lawn growth and can reduce mold growth; the relative humidity should be 50%-70%, as too high a humidity can easily lead to mold growth, while too low a humidity will affect growth; provide 4-6 hours of diffused light or weak artificial light (such as LED lights with an illuminance of 2000-3000 lux) daily, along with regular ventilation (2-3 times a day, 30 minutes each time) to improve air quality.

[0039] 4. Daily maintenance

[0040] Root-promoting solution: Spray after sowing until the lawn is established (about 2-3 weeks). It contains Bacillus laterosporus and Bacillus amyloliquefaciens to promote root development and accelerate lawn establishment.

[0041] Three-in-one maintenance spray: Used after the lawn is established. It is made by inoculating Bacillus thuringiensis (insect repellent), Bacillus licheniformis (pathogenic bacteria killer), and Bacillus mucilaginosa (fertilizer) with chrysanthemum and dandelion fermentation liquid, achieving integrated insect repellency, antibacterial and fertilization.

[0042] Agricultural-free fertilizer: Contains nitrogen, phosphorus, and potassium (3:1:2) and trace elements such as calcium, magnesium, iron, and zinc, combined with Bacillus megaterium (phosphorus solubilizer) and azotobacter brevis (nitrogen fixer) to promote deep green turf leaves and robust plant growth.

[0043] Multifunctional environmental purification spray: It is made by fermentation of photosynthetic bacteria, yeast and actinomycetes, which decomposes indoor chemical residues (such as harmful gases from new decoration) and odors from feces and soil, thus purifying the planting environment.

[0044] Example 1

[0045] Preparation of planting substrate: Take 35 parts by weight of peat moss, 25 parts of coconut coir, 20 parts of perlite, 15 parts of decomposed straw, and 5 parts of decomposed sawdust.

[0050] The three-in-one maintenance spray (chrysanthemum-dandelion fermentation liquid + Bacillus thuringiensis 0.8wt% + Bacillus licheniformis 0.4wt% + Bacillus mucilaginosa 0.3wt%, diluted 80 times) should be sprayed once every 8 days;

[0051] The non-agrochemical fertilizer (nitrogen, phosphorus, potassium 3:1:2 + calcium 0.8wt% + magnesium 0.5wt% + Bacillus megaterium 0.3wt% + azotobacter brownii 0.2wt%) is applied every 18 days;

[0052] The environmental purification spray (0.4wt% photosynthetic bacteria + 0.3wt% yeast + 0.2wt% actinomycetes, diluted 150 times) should be applied once every 3 days.

[0053] Results: The lawn was established in 2 weeks, with no mold, dark green leaves, and no abnormalities after pets came into contact with it; indoor odors were significantly reduced, and environmental testing showed that the concentration of harmful gases such as formaldehyde was lower than the national standard.

[0117] Summary of the effects of the examples

[0118]

[0119] This invention, through five embodiments (including one comparative embodiment), systematically verifies the effectiveness and inventiveness of a "chemical-free, environmentally friendly, and pet-friendly anti-mold indoor lawn planting method" across basic and specialized scenarios, and from experimental to control groups. The design of each embodiment revolves around scenario adaptability and technological synergy, with core variables including:

[0120] Substrate and microbial combination: Adjust the proportion of harmless substrate (such as peat moss and coconut coir ratio) and the types and concentrations of functional microbial species (such as photosynthetic bacteria, Bacillus subtilis, etc.) for different scenarios;

[0121] Environmental control parameters: customized according to lighting, temperature, and ventilation requirements (e.g., adding artificial lighting in low-light environments, and increasing ventilation frequency in newly renovated environments);

[0122] Maintenance plan: Adjust the formula and frequency of use of root-promoting solution, three-in-one maintenance spray, non-agricultural fertilizer and environmental purification spray to suit the needs of the scene (such as increasing the frequency of spray use in multi-pet scenes, and strengthening the spraying interval of purification spray in newly renovated environments).

[0123] Through the biological antagonistic effect of "Bacillus licheniformis + Trichoderma harzianum" (inhibiting pathogenic mycelia and secreting antibacterial substances), combined with environmental humidity control (50%–70%), mold-free conditions are achieved throughout the entire process, replacing traditional chemical antifungal agents. The synergistic effect of compound microorganisms (nitrogen-fixing bacteria + phosphorus- and potassium-solubilizing bacteria + root-promoting bacteria) shortens the turf establishment time by 35%–50%, and the lawn has a deep green leaf color and well-developed root system, which is superior to chemical fertilizers. All materials (substrate, microorganisms, plant fermentation liquid) are harmless to pets / children, and "zero chemical residue" is achieved through microbial degradation, solving the safety hazards of traditional planting. By adjusting the microorganism ratio, environmental parameters, and maintenance frequency, the needs of special scenarios such as low light, multiple pets, and new renovations can be met, breaking through the application limitations of traditional methods.

[0124] The core innovation of this invention lies in the deep integration of "agricultural-free cultivation" with "pet-friendly" and "environmental purification," achieving a breakthrough through the following technological combination:

[0125] Synergistic screening of multifunctional microbial strains: This is not a simple superposition of single strains, but rather a screening of strain combinations with synergistic effects based on the functional requirements of "anti-mold (Trichoderma harzianum), decomposition of excrement (Bacillus subtilis), growth promotion (photosynthetic bacteria), and odor removal (Bacillus coagulans)". For example, Bacillus subtilis + Bacillus mucilaginosus enhances pressure resistance, and photosynthetic bacteria + Streptomyces rubrum and Streptomyces rubrum enhances low light adaptability.

[0126] Customized scenario solutions: Optimizing the entire chain from substrate, grass seeds, environmental control to maintenance measures to address different environmental pressures (insufficient light, pet interference, chemical residues), rather than adjusting a single link;

[0127] "Planting-purification" integration: Combining lawn planting with indoor environmental purification (decomposing toxic gases and odors through multi-functional sprays), making the lawn a "living purifier" and expanding the functional boundaries of indoor planting.

[0128] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
