Description

TECHNICAL FIELD

[0002] The present application belongs to the technical field of deep space plant cultivation, and particularly relates to a deep space potted ornamental plant cultivation method and a spray sterilization device. BACKGROUND

[0003] With the acceleration of urbanization process, land resources are becoming increasingly scarce, and urban development is gradually shifting from horizontal to vertical space development, and the development depth is gradually deepening. The rational development of urban deep space is related to the sustainable development of future cities. Deep space is far away from the natural ecological environment, and the seasonal changes are not obvious, and the direction recognition is poor, which makes people feel depressed and closed. Long-term stay in deep space makes people difficult to adapt. Plants not only absorb carbon dioxide and release oxygen, but also beautify the environment, and can give people a relaxed and comfortable feeling. Therefore, it is necessary to plant healthy and colorful plants in deep space and create a suitable deep space environment for living. SUMMARY

[0004] In order to make up for the shortcomings of the prior art, the present application provides a deep space potted ornamental plant cultivation method and a spray sterilization device, which can build a healthy and stable plant landscape and good air quality in deep space.

[0005] In order to achieve the above purpose, the technical scheme adopted by the present application is: A deep space potted ornamental plant cultivation method, comprising the following steps: 1) Step one: selecting an underground artificial climate chamber to simulate the actual environment of deep space; 2) Step two: selecting a variety of shade-tolerant ornamental plants for planting, monitoring the growth of the plants, and determining the appropriate light intensity for the growth of the shade-tolerant ornamental plants according to the monitoring results; 3) Step three: substrate disinfection, sterilization and insect killing; 4) Step four: planting shade-tolerant ornamental plants in flowerpots, setting the appropriate light intensity for the growth of the shade-tolerant ornamental plants according to step two, and building a deep space plant landscape; 5) Step five: during the growth of the plants, shellac + salicylic acid, shellac nanoparticles, erythritol + shellac are used to spray and treat common ivy aphids, turtleback bamboo thrips and jasmine red spiders for 7 days and 14 days respectively for 2 times; 6) Step six: when the plants have pests, hang a yellow caterpillar board, and put the diseased plants into the spray sterilization device, and use flonicamid, imidacloprid and bifenthrin to spray and kill common ivy aphids, turtleback bamboo thrips and jasmine red spiders respectively.

[0006] Further, in step one, an underground artificial climate chamber that can completely control light, temperature and humidity is selected, and the existing deep space light environment data is combined with the laboratory environmental conditions to set.

Detailed Implementation

[0017] The present invention will now be described in detail with reference to specific embodiments.

[0018] This invention selects shade-tolerant ornamental plants suitable for deep-ground growth and with strong resistance to pests and diseases, reducing the chances of plant diseases and pests; the plant cultivation substrate is disinfected before entering the deep-ground space; non-toxic and pollution-free chitosan and other substances are used to promote healthy plant growth and effectively inhibit bacteria and kill insects; environmentally friendly sticky insect boards and spray insecticidal and sterilization devices are used to avoid spraying in the air; it is low-cost, safe, efficient, and easy to operate, and is suitable for the cultivation, maintenance, and management of plants in any deep-ground space.

[0019] like Figure 1 As shown, the method for cultivating potted ornamental plants in deep underground space according to the present invention includes the following steps: 1) Step 1: Select an underground artificial climate chamber to simulate the actual environment of deep underground space; In step one, an underground artificial climate chamber with fully controllable light, temperature, and humidity is selected and set up based on existing deep-earth space light environment data and laboratory environmental conditions. The deep-earth space environment is enclosed, with constant temperature and humidity, weak light, and poor ventilation. Conducting similar environmental simulation experiments before actual deep-earth space plant cultivation helps to verify and optimize cultivation techniques and provides reliable data support for the deep-earth space environment.

[0020] 2) Step Two: Select a variety of shade-tolerant ornamental plants for planting, monitor plant growth, and determine the appropriate light intensity for the growth of shade-tolerant ornamental plants based on the monitoring results; set up control groups with different light levels to determine the appropriate light intensity for plant growth; in actual cultivation, light can be increased by using lamps to ensure healthy plant growth.

[0021] Purchased 450 pots of 25 healthy indoor ornamental plants from the market, including: Pilea notata, Tradescantia zebrina, Peperomia polybotrya, Alocasia longiloba, Dieffenbachia seguine, Pachira glabra, Asplenium nidus, Hedera nepalensis var. sinensis, Nageia nagi, Ficus elastica, Epipremnum aureum, Calathea concinna, Dracaena marginata 'Tricolor', Monstera deliciosa, Euphorbia pulcherrima, Jasminum sambac, Hosta plantaginea, Pteris fauriei, Peperomiatetraphylla, and Begonia. The following species were included: *Spathiphyllum kochii*, *Philodendron selloum*, *Philodendrontatei 'Congo'*, *Ficus pandurata*, and *Dracaena deremensis 'Roehrs Gold'*. Two light intensity control groups were set up: 50-150 μmol•m⁻²•s⁻¹ and 100-1200 μmol•m⁻²•s⁻¹. Deep-earth environments are enclosed, with constant temperature and humidity, weak light, and poor ventilation. Plants growing under these unfavorable conditions may be susceptible to pests and diseases. Monitoring revealed that, under otherwise identical conditions, plants growing in a light intensity range of 100-1200 μmol•m⁻²•s⁻¹ showed better growth than those growing in the 50-150 μmol•m⁻²•s⁻¹ range. Therefore, in subsequent planting, the light intensity can be set to 100-1200 μmol•m⁻²•s⁻¹, with appropriate adjustments based on specific growth conditions. Furthermore, conventional planting methods were found to result in aphids, thrips, and spider mites affecting ivy, Monstera deliciosa, and jasmine, respectively, requiring combined pest and disease control measures.

[0022] 3) Step 3: Substrate disinfection, sterilization and insect control; Before cultivation, the substrate should be exposed to sunlight for a week, then a soil disinfectant should be applied, diluted and mixed evenly, covered with a film, and sealed for 48 hours to kill insect eggs and reduce the breeding of diseases and pests during the later cultivation process; The substrate is a mixture of coconut coir, perlite and peat soil, and the soil disinfectant is a soil disinfectant with a content of 2% chitosan and 15% hymexazol.

[0023] 4) Step Four: Plant shade-tolerant ornamental plants in flowerpots, set the appropriate light intensity for the growth of shade-tolerant ornamental plants as in Step Two, and construct a deep-ground space plant landscape; adjust the spacing between pots according to different plants and flowerpot sizes, carry out precise cultivation management, and construct a deep-ground space plant landscape.

[0024] Light intensity should be set to 100-1200 μmol·m⁻²·s⁻¹ according to the plant's light requirements. Plant the plants in suitable flowerpots according to their size to ensure healthy root growth. The planting distance or flowerpot placement distance should meet the plant's light requirements and increase ventilation. Adjust the amount and frequency of artificial watering according to the different water requirements of different plants. Diseased leaves, damaged leaves, old leaves, and fallen leaves produced during the plant's growth process should be removed promptly.

[0025] 5) Step Five: During the plant growth process, different concentrations of chitosan + salicylic acid, chitosan nanoparticles, and erythritol + chitosan were sprayed twice for 7 days and 14 days respectively to treat ivy aphids, Monstera thrips, and jasmine red spiders. Chitosan and low-viscosity chitosan have good biocompatibility, biodegradability, non-toxicity, and their metabolic intermediates and final products are harmless to humans. They can promote plant growth, improve the soil environment, promote nutrient absorption, and enhance plant stress resistance. They also have antibacterial, antifungal, antiviral, and insecticidal properties.

[0026] Different control groups were set up, and the ivy aphids were sprayed twice for 7 days and 14 days with chitosan (1500ppm) + salicylic acid (800ppm), chitosan (2000ppm) + salicylic acid (1000ppm), and chitosan (2500ppm) + salicylic acid (1200ppm), respectively. The ivy aphids were sprayed twice for 7 days and 14 days with chitosan nanoparticles (800ppm), chitosan nanoparticles (1000ppm), and chitosan nanoparticles (1200ppm). The jasmine red spider mite was sprayed twice for 7 days and 14 days with erythritol (1.5%) + chitosan (1.5%), erythritol (2%) + chitosan (2%), and erythritol (2.5%) + chitosan (2.5%). Monitoring revealed that chitosan (2000 ppm) + salicylic acid (1000 ppm) was most effective in controlling ivy aphids, with aphid mortality rate reaching 95% after 14 days; chitosan nanoparticles (1000 ppm) were most effective in controlling Monstera deliciosa thrips, with thrips mortality rate reaching 88% after 14 days; and erythritol (2%) + chitosan (2%) was most effective in controlling jasmine spider mites, with spider mite mortality rate reaching 90% after 14 days.

[0027] 6) Step Six: When plants are infested with pests and diseases, hang yellow sticky insect traps and place the affected plants in a spray sterilization device. Use flupyradifurone, imidacloprid, and bifenazate to spray and kill ivy aphids, monstera thrips, and jasmine spider mites, respectively, to avoid polluting the deep-ground living environment. Spray the pesticide for 5 minutes, leave it for a while, and then remove it.

[0028] like Figure 2 As shown, in step six, the spray sterilization device includes a device housing 1, a device door 5, and a device door handle 6 on the device door 5; a turntable 10 is installed inside the device housing 1, and a potted plant 7 is installed on the turntable 10; a liquid tank 11 is installed at the bottom of the device housing 1, and the liquid tank 11 is connected to the spray head 4 through a pressurizing device 9 and a spray pipe 3; a switch 8 is installed on the pressurizing device; an electrical wire 12 is installed outside the device housing 1; a push-pull handle 2 is installed at the top of the device housing 1; and a pulley 13 is installed at the bottom of the device housing 1.

[0029] Different control groups were set up. Potted ivy was sprayed with flonicamid (10% flonicamid at 1500 times dilution), flonicamid (10% flonicamid at 2000 times dilution), and flonicamid (10% flonicamid at 1000 times dilution). Potted Monstera deliciosa was sprayed with imidacloprid (1 gram imidacloprid diluted in 1000 ml of water), imidacloprid (1 gram imidacloprid diluted in 800 ml of water), and imidacloprid (1 gram imidacloprid diluted in 1200 ml of water). Potted jasmine was sprayed with bifenazate (45% bifenazate formulation at 2000 times dilution), bifenazate (45% bifenazate formulation at 2500 times dilution), and bifenazate (45% bifenazate formulation at 3000 times dilution). Monitoring revealed that spraying flonicamid (10% flonicamid diluted 1500 times) for 5 minutes resulted in a 100% kill rate of aphids on potted ivy; spraying imidacloprid (1 gram of imidacloprid diluted in 1000 ml of water) for 5 minutes resulted in a 100% kill rate of thrips on potted Monstera deliciosa; and spraying bifenazate (45% bifenazate SC2500 times liquid) for 5 minutes resulted in a 100% kill rate of spider mites on potted jasmine.
