Abstract
Description
Technical Field
[0001] This invention relates to a method and apparatus for promoting the growth of indoor potted plants. Background Technology
[0002] Indoor potted plants, due to lack of light, poor ventilation, and the influence of the light spectrum, are more prone to having weak stems, low photosynthetic efficiency, and less nutrient accumulation compared to outdoor plants. Summary of the Invention:
[0003] To address the aforementioned problems, this invention designs a method for heterotrophic cultivation of plants using organic carbon sources, promoting nutrient accumulation and other life activities under conditions of insufficient accumulated temperature and light, thereby maintaining their growth and ornamental value.
[0004] Specific technical solution:
[0005] By burying an organic carbon source steam supply device in the roots of potted plants and increasing the permeability of the potting soil, and by combining potassium indolebutyrate and sodium naphthaleneacetate to enhance root growth and development, the efficiency of organic matter absorption and metabolism is increased. At the same time, potassium acetate is used to inhibit miscellaneous bacteria in the soil, which promotes the growth of the underground biomass of the plant and forms a development mode that is mainly heterotrophic and supplemented by autotrophic. Paclobutrazol is used to inhibit its excessive growth.
[0006] (1) Selection of potting soil: To ensure the normal life activities of the roots under high-speed absorption of organic carbon sources, the potting soil must be made of materials that are not prone to waterlogging and are loose and breathable. Such as a mixture of peat moss and perlite, volcanic rock fragments, artificially sintered akadama soil, ceramsite, activated carbon granules, charcoal powder, etc. The preferred mixture is a 1:1 mixture of 0.5-1mm diameter activated carbon and charcoal granules with peat moss, which has a strong adsorption effect on both organic matter and water, and can minimize the loss of organic carbon sources into the air and increase the utilization rate of organic matter.
[0007] (2) Structural design and function of the device: To ensure the stability of the absorption rate and supply rate of organic vapor, this device (see attached instructions) Figure 1The device comprises a root diffuser (6), a conduit (4), a valve (5), a carbon source bottle (1), and a porous ceramic ring (2) inside the carbon source bottle. Specifically, the carbon source bottle is a sealed structure of any shape and size, connected to the outside air only by the conduit, and is used to hold volatile organic carbon sources. It contains a porous ceramic ring filling the internal space of the carbon source bottle, which increases the contact area between the liquid and the air inside the bottle, accelerates the evaporation of moisture and organic carbon sources, increases the humidity and concentration of organic carbon sources in the air, and facilitates diffusion along the conduit at a fixed rate. The conduit is preferably made of aging-resistant and highly sealing PVC material, and has a valve in the middle to regulate the release rate of the carbon source. Its function is to transport moisture and organic vapors. The conduit connects to the root diffuser, a small container with a downward-facing open end, which prevents the cultivation substrate from clogging the conduit and increases the absorption efficiency of the plant roots.
[0008] (3) The composition ratio of organic carbon source: each liter of solution contains 3-15 ml of acetic acid, 200-300 ml of ethanol, 20-50 ml of ethyl acetate, 5-15 ml of ethyl octanoate, and the remaining components are purified water, preferably 3 ml of acetic acid per liter, 200 ml of ethanol per liter, 50 ml of ethyl acetate per liter, and 15 ml of ethyl octanoate per liter.
[0009] (4) Practical Application: Place the organic carbon source into the carbon source bottle, ensuring the liquid level is below half the vertical height of the bottle's interior to facilitate vapor diffusion. Connect the carbon source bottle to the root diffuser using a conduit. Remove the plant roots from the soil and allow them to wrap around the root diffuser. Then, bury the plant in the pot using a 1:1 mixture of 0.5-1mm diameter activated carbon and peat moss as a substrate. Close the valve on the conduit 1-3 days before the plant roots adapt to the environment to prevent infection during this pre-adaptation period. Once the plant shows signs of root adaptation, open the valve one-quarter of the way. When the plant exhibits significant accelerated growth, fully open the valve.
[0010] (5) Prevent excessive vegetative growth and promote root development: Drench the roots with a mixed solution of paclobutrazol (0.05-1 / 1000), sodium naphthaleneacetate (0.1-0.2 / 1000), and potassium indolebutyrate (0.05-0.15 / 1000). Use any brand of all-element compound fertilizer according to the instructions, or use sugar-free, agar-free MS medium at a concentration of 0.1-0.3 / 1000. The preferred concentration is sugar-free, agar-free MS medium at 0.3 / 1000.
[0011] Attached image description: Figure 1 This is a schematic diagram of the present invention, in which the numbers correspond to 1: carbon source bottle, 2: ceramic ring, 3: organic carbon source liquid surface, 4: conduit, 5: valve, and 6: root diffuser.
[0012] Example: Portulaca grandiflora (sunflower) was used as the indoor cultivation experimental subject. Twenty healthy branches, each 10 cm long, were taken for cutting propagation. After the roots were clearly visible, they were dug up, and 10 plants were selected as experimental plants and 10 plants as control plants. The same 1:1 mixture of 0.5-1 mm diameter activated carbon and peat moss was used as the substrate for cultivation. The experimental group used the same equipment and carbon source. The roots were drenched with a mixed solution of paclobutrazol at a concentration of 0.1% and sodium naphthaleneacetate at a concentration of 0.2% and potassium indolebutyrate at a concentration of 0.15% and a sugar-free, agar-free MS medium at a concentration of 0.3% every 3 days. The growth was observed over 30 days.
[0013] Experimental results: Under summer temperatures of 26-38 degrees Celsius, after 30 days, the experimental group had an average crown width of 25cm and an average of 5 flowers, while the control group had an average crown width of 18cm and an average of 3 flowers.
[0014] Conclusion: The experimental group showed a significant growth advantage and nutrient accumulation compared to the control group.
