Description

Landscape plant growth device Technical Field

[0001] This utility model relates to the field of landscape plant technology, and in particular to a landscape plant growth device. Background Technology

[0002] With the acceleration of urbanization and the increasing density of urban spaces, green areas are shrinking, leading to a series of ecological and environmental problems such as the intensification of the heat island effect, worsening air pollution, and declining biodiversity. Against this backdrop, building exterior greening (vertical greening) has become an important means of improving the urban ecological environment as an efficient way of utilizing space. Building exterior greening involves placing multiple landscape plant growth devices on the exterior facade, balconies, roofs, and other areas of buildings, planting plants on these devices, and constructing a three-dimensional greening system. This not only increases the urban green coverage rate but also improves the urban ecological environment.

[0003] One related technology is a landscape plant growth device, which includes an open container without a top cover. The side wall of the open container is fixedly connected to the bottom plate, and several drainage holes are evenly arranged on the bottom plate. Soil is placed in the open container, and landscape plants are planted in the soil.

[0004] In the process of realizing this utility model, the inventors discovered that the related technology has at least the following problems: the outdoor environment is complex and there will be heavy rain, drought and other situations. The root system of plants has different requirements for soil moisture at different growth stages. The drainage hole at the bottom of the plant growth device cannot adjust the drainage volume, which will result in insufficient drainage during heavy rain or insufficient water retention during drought. This causes the soil moisture and oxygen content in the plant growth device to fluctuate drastically, and the stability of the microbial community in the soil is destroyed, resulting in poor plant growth in the landscape plant growth device.

Detailed Implementation

[0037] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0038] Figure 1 is a structural schematic diagram of a landscape plant growth device according to an embodiment of the present invention. Figure 2 is an exploded view of the landscape plant growth device shown in Figure 1. Figure 3 is a bottom view of the landscape plant growth device shown in Figure 1. As shown in Figures 1, 2 and 3, the landscape plant growth device is used to plant landscape plants with root systems. The landscape plant growth device includes a box body 1 and a baffle 2. The box body 1 includes a side wall 11, a bottom plate 12 and a protrusion 13. The top of the box body 1 has a first opening 14. The bottom plate 12 is connected to the end of the side wall 11 away from the first opening 14. The bottom plate 12 has a plurality of drainage holes 121 arranged in rows and columns. The protrusion 13 is a vertical plate with opposite ends. The end of the opposite ends closer to the side wall 11 is connected to the edge of the bottom plate 12. The protrusion 13 is located on the side of the bottom plate 12 away from the first opening 14. The protrusion 13 has a second opening 131.

[0039] The baffle 2 includes a plurality of strip-shaped sub-baffles 21 spaced apart and arranged in parallel. The width of each strip-shaped sub-baffle 21 in the parallel arrangement direction is greater than the diameter of the drain hole 121. The number of strip-shaped sub-baffles 21 is the same as the number of rows of drain holes 121. The baffle 2 passes through the second opening 131 and is slidably connected to the protrusion 13. The extending direction of the baffle 2 is parallel to the extending direction of the base plate 12, and the baffle 2 is located on the side of the base plate 12 away from the first opening 14.

[0040] In this design, the width of each strip-shaped sub-baffle 21 in the parallel arrangement direction is greater than the diameter of the drainage hole 121. This means each sub-baffle 21 can block a row of drainage holes 121, preventing drainage. By sliding the baffle 2, its position can be adjusted to block different sizes of drainage holes 121, allowing for quick switching of drainage modes (e.g., fully open, partially closed, or fully closed). Figure 3 shows a bottom view of the fully open drainage mode. During heavy rain, the baffle 2 can be slid to the fully open mode, where the strip-shaped sub-baffles 21 completely expose the drainage holes 121, allowing for significant drainage and preventing rainwater from being stored in the landscape plant growth device. Figure 4 shows a bottom view of another landscape plant growth device as shown in Figure 1, illustrating the fully closed drainage mode. During dry weather, the baffle 2 can be slid to the fully closed mode, where multiple strip-shaped sub-baffles 21 completely block multiple rows of drainage holes to retain water. Figure 5 is a bottom view of another landscape plant growth device shown in Figure 1. Figure 5 shows a bottom view of a semi-closed drainage mode with baffles. Under normal weather conditions, the baffles 2 can be slid to the semi-closed drainage mode. In the semi-closed drainage mode, as shown in Figure 5, each strip-shaped sub-baffle 21 can block half of a row of drainage holes 121 for daily slow-release drainage, balancing water retention and aeration. By flexibly adjusting the baffles 2, the soil moisture and oxygen content in the landscape plant growth device can be kept in a stable state, thereby ensuring the stability of the microbial community in the soil and providing good conditions for plant growth in the landscape plant growth device.

[0041] In summary, the landscape plant growth device provided in this embodiment of the present invention includes a box body comprising a side wall, a bottom plate, and a protrusion. A first opening is located at the top of the box body. The bottom plate is connected to the side wall at the end furthest from the first opening. The bottom plate has multiple drainage holes arranged in rows and columns. The end of the protrusion near the side wall is connected to the edge of the bottom plate. The protrusion is located on the side of the bottom plate furthest from the first opening. The baffle includes multiple strip-shaped sub-baffles arranged in parallel and at intervals. The width of each strip-shaped sub-baffle in the parallel arrangement direction is greater than the diameter of the drainage hole. The number of sub-baffles is the same as the number of rows of drainage holes. The extending direction of the baffle is parallel to the extending direction of the bottom plate, and the baffle is located on the side of the bottom plate furthest from the first opening. The protrusion has a second opening, through which the baffle passes and is slidably connected to the protrusion. A strip-shaped baffle can block a row of drainage holes. By sliding and adjusting the position of the baffle, the area of ​​the drainage holes blocked by the baffle can be adjusted, thus flexibly controlling the drainage speed or flow rate according to the outdoor environment. This maintains stable soil moisture and oxygen content in the plant growth device, solving the problem of poor plant growth caused by the disruption of soil microbial community stability in related technologies. It achieves the effect of maintaining a stable and healthy microbial community and promoting good plant growth.

[0042] As shown in Figure 1, the box body 1 also includes scale lines 15, which are located on the side wall 11 facing the interior of the box body. The scale lines 15 are evenly arranged in a direction away from the bottom plate 12. Soil can be filled into the box body 1 through the scale lines 15, eliminating the need for additional weighing tools and allowing for precise measurement of the amount of soil. The scale lines 15 can also be located on the side wall 11 facing the exterior of the box body; this embodiment of the invention does not limit this. Furthermore, in this embodiment of the invention, the scale markings are in centimeters, and the scale markings are related to the dimensions of the box body; the specific numerical values ​​of the markings are not limited in this embodiment of the invention.

[0043] Figure 6 is a partial structural schematic diagram of the landscape plant growth device shown in Figure 1. Figure 6 shows a structural schematic diagram of a partition. Figure 7 is a cross-sectional view of the box body in another landscape plant growth device according to an embodiment of the present invention. As shown in Figures 6 and 7, the landscape plant growth device also includes two partitions 3. The two partitions 3 are respectively connected to the side wall 11 at different positions inside the box. The two partitions 3 are arranged parallel to the bottom plate 12, dividing the box body into an air-permeable layer 16, a fertilizer layer 17, and a drainage layer 18. The drainage layer 18, the fertilizer layer 17, and the air-permeable layer 16 are arranged sequentially in a direction away from the bottom plate 12. The two partitions 3 each have a first through hole 31 arranged opposite to each other. The roots of the landscape plants can pass through the first through hole 31 and reside in the air-permeable layer 16, the fertilizer layer 17, and the drainage layer 18. The soil design incorporates aeration layer 16, fertilizer layer 17, and drainage layer 18, each containing different types of soil. For example, aeration layer 16 can hold well-aerated, lightweight loam suitable for plants with high oxygen requirements; fertilizer layer 17 can hold fertile soil rich in organic matter, providing the main nutrient source for plants; and drainage layer 18 can hold well-drained rock soil to prevent water retention and provide deep root space for plant growth. This multi-layered soil design not only provides a suitable growing environment for plants but also offers diverse habitats for soil microbial communities, promoting their growth and reproduction. The drainage layer 18 can be 3-10 cm high, the fertilizer layer 17 5-15 cm high, and the aeration layer 16 2-5 cm high, with varying soil thicknesses in each layer. This multi-layered soil design not only provides a suitable growing environment for plants but also offers diverse habitats for soil microbial communities, promoting their growth and reproduction.

[0044] Referring again to Figures 6 and 7, each partition 3 also has multiple second through holes 32 arranged around the first through hole 31. The diameter of the second through holes 32 is smaller than the diameter of the first through hole 31, and the multiple second through holes 32 on the two partitions 3 are arranged opposite each other. Typically, multiple plants can be planted in each landscape plant growth device, and the multiple second through holes 32 allow the roots of multiple plants to pass through, so the diameters of the multiple second through holes 32 can be different.

[0045] As shown in Figure 1, the landscape plant growth device also includes a sensor (not shown in Figure 1) and a sensor fixing bracket 4. The sensor fixing bracket 4 is connected to one end of the side wall 11 located at the first opening 14. The sensor fixing bracket 4 has a fixing through hole 41. The sensor passes through the fixing through hole 41 and is engaged with the fixing through hole 41.

[0046] As shown in Figure 1, the sensor mounting bracket 4 is an arc-shaped plate with two fixing holes 41. The sensors, including a humidity sensor and a temperature sensor, extend into the box body 1 through the two fixing holes 41. The humidity sensor and temperature sensor can be needle-type humidity sensors and needle-type temperature sensors, respectively. Silicone sealing rings can also be embedded in the two fixing holes 41 on the arc-shaped plate to ensure a tight fit after insertion and prevent the sensors from falling out. The humidity sensor and temperature sensor can detect the temperature and humidity inside the box. The humidity data inside the box can determine whether the opening and closing of the drain hole needs to be adjusted to prevent excessive humidity from disrupting the stability of the microbial community. The temperature sensor can detect the internal temperature of the box and alert staff to take appropriate measures, such as insulating the box, when the temperature is too high or too low.

[0047] As shown in Figure 2, the protrusion 13 and the side wall 11 are an integral structure. The integrally formed protrusion 13 and side wall 11 avoid stress concentration points that may be generated by welding, bolting and other joint methods. The overall stress is more uniform, the structure has high strength and strong resistance to deformation, and it can extend the service life of the landscape plant growth device in complex outdoor environments.

[0048] As shown in Figures 1 and 2, the base plate 12 is a rectangular base plate. The opening distance of the second opening 131 is the same as the length of one side of the base plate 12. The width of the baffle 2 is the same as the opening distance of the second opening 131. The baffle 2 can be stuck in the protrusion 13 by friction and will not fall off. The baffle 2 can be moved in the protrusion 13 by a certain pulling or pushing force. The above structure is a relatively simple structure among the current sliding structures, which can greatly save the manufacturing cost of landscape plant growth devices.

[0049] Optionally, this application embodiment also provides another slidable structure between the baffle and the protrusion. The side of the protrusion near the baffle has a strip-shaped groove, and the surface of the baffle that contacts the protrusion has a straight tenon. The baffle slides in the second opening via a straight tenon slide rail formed by the combination of the straight tenon and the groove. The straight tenon is an elongated protrusion, and is one type of mortise and tenon joint, consisting of a protruding "tongue" and a corresponding "groove," which engage to achieve sliding or fixing. The sliding connection between the baffle and the protrusion can also be in other ways, which are not limited in this embodiment.

[0050] Optionally, the gap between the baffle and the base plate in the extending direction of the sidewall ranges from 0.5 mm to 1.2 mm. Setting a gap range between the base plate and the baffle, with a lower limit greater than or equal to 0.5 mm, ensures smooth sliding between them, reduces friction surfaces, and prevents mechanical jamming caused by deformation due to thermal expansion and contraction. An upper limit less than or equal to 1.2 mm prevents the baffle from wobbling due to an excessively large gap, thus affecting sliding accuracy and sealing. Furthermore, a gap that is too small is easily clogged by dirt, increasing sliding resistance; a gap that is too large can easily trap particles. The gap setting allows for a small amount of liquid leakage without affecting the overall drainage function.

[0051] This utility model provides three different sizes of landscape plant growth devices for planting plants of different sizes. Figure 8 is a schematic diagram of the structure of the three different sizes of the landscape plant growth device shown in Figure 1. Exemplary devices are as follows: Landscape plant growth device A: 9000 cm3 (length 10cm × width 30cm × height 30cm), with 12 holes at the bottom, each with a diameter of 1cm and a spacing of 5cm, for small plant growth; Landscape plant growth device B: 9000 cm3 (length 30cm × width 30cm × height 10cm), with 36 holes at the bottom, each with a diameter of 1cm and a spacing of 5cm, suitable for medium-sized plants; Landscape plant growth device C: 12000 cm3 (length 20cm × width 30cm × height 20cm), with 24 holes at the bottom, each with a diameter of 1cm and a spacing of 5cm, for large plants.

[0052] The drainage performance of the three different sizes of landscape plant growth devices and traditional containers was verified. The drainage efficiency of the drainage holes at the bottom of the landscape plant growth devices was tested, the amount of water discharged per unit time was measured, and the results were compared with those of traditional plant containers, as shown in Table 1.

[0053] Table 1. Drainage efficiency of different landscape plant growing devices and traditional containers

[0054] Number of drainage holes in landscape plant growth device; Drainage hole spacing (cm); Drainage efficiency (L / min); Landscape plant growth device A: 125; 0.15; Landscape plant growth device B: 365; 0.30; Landscape plant growth device C: 245; 0.25; Traditional container: 87; 0.10 surface

[0055] Results analysis: Landscape plant growth device B has the highest drainage efficiency. The optimized design of the number and diameter of drainage holes improves the drainage speed, effectively reduces water retention, and avoids water accumulation at the roots.

[0056] The microclimate and environmental adaptability of the three landscape plant growth devices of different sizes were verified. Under the design of landscape plant growth devices of different sizes, microclimate parameters such as soil temperature and humidity were measured, and their effects on plant growth and microbial activity were analyzed, as shown in Table 2:

[0057] Table 2 Soil microclimate parameters and microbial activity data for different landscape plant growth devices

[0058]

[0059] Results analysis: The soil temperature and humidity were suitable under the design of landscape plant growth device C, and the microbial activity was the strongest, indicating that landscape plant growth device C provided the best growth environment for plants and microorganisms.

[0060] The plant growth effect of the three landscape plant growth devices of different sizes was verified. The same type of plants were selected and planted in landscape plant growth device A, landscape plant growth device B and landscape plant growth device C respectively. The growth indicators such as root growth length, plant height, leaf area and biomass were measured, as shown in Table 3.

[0061] Table 3. Plant growth effects under different landscape plant growth devices

[0062]

[0063]

[0064] The landscape plant growth device C exhibited the most significant plant growth effect, with higher root length, plant height, leaf area, and biomass than both landscape plant growth devices A and B. The larger size of the device and the layered soil configuration provided more space and nutrients, thus promoting plant growth.

[0065] Soil microbial community diversity was validated using three landscape plant growth devices of different sizes. Soil samples from different layers within the devices were collected using 16S rRNA gene sequencing or metagenomic analysis to analyze the α- and β-diversity of the soil microbial community. The Shannon Index (also known as the Shannon diversity index) is used to measure species diversity within a community; the Chao1 index is a species richness estimation index used to estimate the total number of species in a community, commonly used in ecology to estimate species richness; and the Bray-Curtis similarity is an ecological indicator used to measure the similarity of species composition between two community samples. The results are shown in Table 4.

[0066] Table 4. Effects of different soil sizes and soil stratification on soil microbial communities.

[0067]

[0068]

[0069] Results Analysis: Different sizes of landscape plant growing devices and soil stratification configurations significantly affected the soil microbial community. The soil microbial diversity was higher under landscape plant growing device C, indicating that deeper soil layers and larger plant growing device volumes promoted microbial community diversity. The Shannon and Chao1 indices showed that the microbial communities of landscape plant growing devices C and B were richer than those of landscape plant growing device A.
