Technical Field
[0001] This utility model relates to the field of wild pea root tiller technology, and in particular to a simple device for growing wild pea root tillers. Background Technology
[0002] Wild pea (Vicia sativa) is a perennial herb belonging to the genus Vicia in the legume family. It grows to a height of 30-100 cm, with sparse, soft hairs, rarely nearly hairless. It has a stout taproot and well-developed fibrous roots. The stems are angular, much-branched, slender, and ascending or climbing. The leaves are even-pinnate compound, 5-12 cm long, nearly sessile, with 2-3 branched tendrils at the apex; stipules are semi-sagittate, 0.8-2 cm long, with 3-4 lobes along the margin; leaflets are in 4-7 pairs, alternate or nearly opposite, elliptic to ovate-lanceolate, 1.3-4 cm long and 0.5-1.8 cm wide; apex rounded, slightly concave, base nearly rounded, upper surface covered with appressed long soft hairs, lower surface powdery white; hairs are denser along the midrib, lateral veins fan-shaped extending to the leaf margin. The racemes are usually longer than the leaves; 10-20(-30) flowers are densely clustered on the upper part of the inflorescence axis; the corolla is reddish-purple, bluish-purple, or blue, with varying colors during flowering; the calyx is obliquely campanulate, with nearly triangular teeth, the upper teeth 0.3-0.4 cm long, significantly shorter than the lower teeth; the standard is obovate, 1-1.6 cm long and 0.5-0.6 cm wide, slightly emarginate at the apex, with a relatively wide claw; the wings are nearly equal in length to the standard, with obliquely obovate blades and claws 0.4-0.5 cm long; the keel is shorter than the wings, 1.1-1.2 cm long; the ovary is glabrous, with 6 ovules, the upper part of the style pubescent around the periphery, and the ovary stalk about 0.4 cm long. The pod is oblong, 1.8-2.8 cm long and 0.4-0.6 cm wide, acuminate at both ends, and glabrous. Seeds 1-6, round, 0.35-0.4 cm in diameter; seed coat leathery, dark brown, mottled; hilum concave, yellowish-brown, about 1 / 3 the length of the seed circumference. Flowering from April to June, fruiting from July to October.
[0003] Meanwhile, root suckers, as important reproductive organs of underground parts of plants, usually occur in the deep soil or in the basal area close to the main root. Their development process is completely in a closed soil environment, which is highly concealed and invisible. Due to the physical shielding effect of soil particles, researchers cannot directly observe the occurrence time, growth process and spatial distribution pattern of root suckers with the naked eye. In order to obtain complete root samples, traditional research methods mostly rely on manual digging and mechanical cutting to collect roots. However, such operations are not only time-consuming and laborious, but also very easy to damage the root structure, especially for small and fragile root suckers, which are often broken or lost during the sampling process, resulting in data distortion. Utility Model Content
[0004] To overcome the problem that root suckers typically occur deep in the soil or near the main root, making them difficult to observe and sample directly, which poses a significant challenge to related research, this invention provides a simple device for the growth of wild pea root suckers.
[0005] The technical solution is as follows: A simple device for the growth of wild pea root suckers includes a culture frame, a growth component, and an auxiliary component; an auxiliary component is installed on the outside of the culture frame for convenient observation of the growth status of wild pea root suckers, and a growth component is installed inside the culture frame for simple and efficient induction of root sucker growth; the growth component includes an installation groove, and multiple sets of installation grooves are sequentially opened from left to right on the upper surface of the culture frame. Two sets of first sliding grooves for fixing baffles are symmetrically opened on the lower end of the installation grooves inside the culture frame, and baffles for inducing root sucker growth are slidably connected inside the first sliding grooves.
[0006] Furthermore, a pull plate corresponding to the first sliding groove is fixedly connected to the center of the upper surface of the baffle plate, and extension holes are opened on the upper surface of the culture frame at the front end of the mounting groove.
[0007] Furthermore, multiple sets of ventilation grooves are sequentially formed from left to right on the lower surface of the cultivation frame to provide good oxygen for the root suckers to grow in the nutrient soil.
[0008] Furthermore, the auxiliary components include observation slots, with multiple sets of observation slots sequentially opened from left to right on the side surface of the culture frame.
[0009] Furthermore, a support plate is fixedly connected to the lower side of the observation slot, and second sliding grooves are symmetrically opened on both sides of the support plate.
[0010] Furthermore, a sunshade plate is slidably connected inside the second sliding groove, and fastening plates are fastened to both ends of the culture frame.
[0011] Furthermore, an insect-proof board is fixedly connected to the front end of the snap-fit plate, and multiple sets of ventilation grooves are symmetrically opened on the upper and lower sides of the front end of the insect-proof board.
[0012] Furthermore, a connecting rod is fixedly connected to the center of the insect-proof board surface, and a handle is fixedly connected to the front end of the connecting rod.
[0013] The beneficial effects are as follows: This invention enables more effective guidance of root growth direction through specially designed growth components, including baffles and other parts, thereby focusing on inducing root sucker formation and improving the success rate and quality of root sucker induction. The device is equipped with auxiliary components on the outside, especially the design of multiple observation slots, which allows researchers to conveniently observe the growth status of wild pea root suckers without destructive sampling. This not only helps to identify and solve problems that occur during the growth process in a timely manner, but also provides accurate data support for scientific research. The ventilation slots set on the lower surface of the cultivation frame can provide a good oxygen environment for the growth of root suckers in the nutrient soil. Compared with the problem of poor ventilation caused by compaction in traditional soil, this design significantly improves the respiration conditions of the roots and is conducive to promoting healthy growth.

Detailed Implementation
[0020] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0021] Among the currently discovered feasible technologies, the following are described:
[0022] Wild pea (Vicia amoena Fisch. ex DC), belonging to the genus Vicia in the family Fabaceae, is a perennial herb widely distributed in northern China. Its natural distribution also extends to the Mongolian Plateau and parts of Russia, commonly found at altitudes of 800–3000 meters in forest edges, shrub margins, hillside grasslands, wastelands, and slightly saline-alkali soils, demonstrating broad ecological adaptability. The plant exhibits diverse morphology, typically growing upright or semi-climbing. The stems are quadrangular, often covered with short, soft hairs or nearly hairless, exhibiting some resistance to wind erosion and reduced water transpiration. The leaves are even-pinnate compound leaves with well-developed tendrils at the apex, aiding in climbing and support. The stipules are semi-sagittate or ovate, and the leaflets are opposite, generally 4–8 pairs, mostly elliptical or lanceolate in shape, with a smooth upper surface and densely covered with fine hairs on the underside, which not only improves photosynthetic efficiency but also helps reduce water evaporation and enhance drought resistance. The flowers are predominantly purple or light purple, with axillary racemes bearing 5-12 flowers per inflorescence. Flowering occurs mainly from May to July. The fruit is an oblong pod, maturing mostly in August and September, containing 4-6 round or kidney-shaped seeds, typically yellowish-brown or dark brown in color. As a typical legume, one of the most significant biological characteristics of *Vicia sativa* is its ability to form a symbiotic relationship with rhizobia, converting atmospheric nitrogen into ammoniacal nitrogen that the plant can absorb and utilize. This effectively increases soil nitrogen content and plays a crucial role in the nutrient cycle of grassland ecosystems. This nitrogen-fixing ability makes it a key species not only for the restoration of degraded grassland vegetation, soil erosion control, and ecological restoration projects in mining areas, but also for use as a green manure crop in agricultural production, in crop rotation and intercropping systems to improve soil fertility, reduce fertilizer use, and promote sustainable agricultural development. Furthermore, *Vicia sativa* possesses strong environmental adaptability and physiological resilience, enabling it to grow normally under various adverse conditions such as drought, low temperatures, and poor soil. Studies have shown that this species can effectively cope with abiotic stress by regulating stomatal opening and closing, accumulating osmotic regulators (such as proline and soluble sugars), and enhancing antioxidant enzyme activity, exhibiting good cold resistance, drought resistance, and salt tolerance.
[0023] Root suckers, as important reproductive organs in the underground parts of plants, play an irreplaceable role in the natural regeneration, spatial expansion, and stress adaptation of plant populations. They not only help plants maintain growth vigor and reproductive capacity under adverse environmental conditions but also are crucial for population stability and niche expansion. However, root suckers typically occur in the deep soil layers or near the base of the taproot, and their entire development occurs within a completely enclosed soil environment, exhibiting high levels of concealment and invisibility. Due to the physical shielding effect of soil particles and the limitations imposed by the complex root structure, researchers find it difficult to directly observe the timing, growth process, and spatial distribution of root suckers with the naked eye. This poses a significant challenge to the dynamic monitoring and phenotypic characterization of root structure. To obtain complete root samples for morphological, physiological, and molecular biological studies, traditional research methods often rely on manual digging and mechanical cutting for root collection. However, such operations are not only labor-intensive and time-consuming but also easily cause irreversible damage to the root structure. Especially for small, delicate root suckers, they are often broken, detached, or even completely lost during sampling due to external forces, severely affecting sample integrity and data accuracy. Furthermore, root suckers often resemble other root systems such as lateral roots and fibrous roots in morphology, and their diverse locations and dense arrangement make manual separation and identification extremely difficult. Even experienced researchers are prone to misjudgment or omission without visual aids, affecting the scientific validity and reproducibility of experimental results. Adding to the complexity, root sucker development is not a random process but is precisely regulated by various internal and external factors. Studies have shown that plant hormones (such as auxins, cytokinins, and gibberellins) play a crucial regulatory role in the initiation and elongation of root suckers; simultaneously, external environmental factors such as water supply, light intensity, nutrient status, and soil aeration also significantly affect the frequency and quality of root sucker development. The formation of root suckers exhibits significant spatiotemporal heterogeneity, with substantial differences between individuals and even between different root segments of the same plant, further increasing the difficulty of research. Traditional soil cultivation systems lack the ability to monitor and control these key variables in real time, severely limiting in-depth analysis and systematic research on their developmental mechanisms. Therefore, constructing a research platform capable of visualizing the root sucker formation process under non-destructive conditions, facilitating precise sampling and quantitative analysis, has become a critical issue that needs to be addressed in plant root biology, reproductive ecology, and breeding applications. Developing novel root research devices with transparent observation windows, controllable culture environments, and adjustable induction structures will help overcome the limitations of traditional research methods, improve the accuracy and efficiency of root sucker-related research, and provide solid technical support for revealing their developmental mechanisms, optimizing propagation strategies, and screening superior germplasm resources.
[0024] like Figures 1-5As shown, a simple device for growing wild pea root suckers includes a cultivation frame 1, a growth component, and an auxiliary component. An auxiliary component is installed on the outside of the cultivation frame 1 for easy observation of the growth status of wild pea root suckers. A growth component for simply and efficiently inducing root sucker growth is installed inside the cultivation frame 1. The growth component includes an installation groove 201. Multiple sets of installation grooves 201 are sequentially opened from left to right on the upper surface of the cultivation frame 1. Two sets of first sliding grooves 204 are symmetrically opened on the lower end of the installation grooves 201 inside the cultivation frame 1 to fix baffles 205. Baffles 205 for inducing root sucker growth are slidably connected inside the first sliding grooves 204.
[0025] A pull plate 206 corresponding to the first sliding groove 204 is fixedly connected to the center of the upper surface of the baffle 205. Extension holes 202 are opened on the upper surface of the cultivation frame 1 at the front end of the mounting groove 201 to facilitate manual adjustment of the position of the baffle 205 and realize flexible control of the root growth area. Multiple sets of ventilation grooves 203 are opened from left to right on the lower surface of the cultivation frame 1 to provide good oxygen for the root suckers to grow in the nutrient soil, providing a good root ventilation environment and promoting the healthy development of the root suckers.
[0026] During operation, the cultivation frame 1 serves as the overall support structure. The mounting groove 201 on its upper surface is used to place wild pea plants or nutrient soil modules. By inserting the baffle 205 along the first sliding groove 204, the root growth area can be separated and guided, achieving directional induction of root sucker growth. The baffle 205 protrudes from the extension hole 202 through a pull plate 206 fixed at its center, allowing operators to manually adjust its position and flexibly control root distribution and growth space. Simultaneously, the ventilation groove 203 on the lower surface of the cultivation frame 1 continuously provides fresh air to the roots, ensuring sufficient oxygen within the nutrient soil and promoting healthy root sucker development.
[0027] Please see Figures 3-4The auxiliary components include observation slots 301. Multiple sets of observation slots 301 are sequentially formed on the side surface of the cultivation frame 1 from left to right, enabling non-destructive real-time observation of the growth status of wild pea root tillers. A support plate 304 is fixedly connected to the lower side inside the observation slot 301. Second sliding grooves 303 are symmetrically formed on both sides of the support plate 304, providing structural support for the stable installation and sliding adjustment of the sunshade plate 302. The sunshade plate 302 is slidably connected inside the second sliding groove 303. Fastening plates 30 are fastened to both ends of the cultivation frame 1. 8. The shading intensity can be flexibly adjusted according to the light requirements, and the overall sealing and protection of the device can be improved. The front end of the snap-fit plate 308 is fixedly connected to the insect-proof plate 305. The front end of the insect-proof plate 305 has multiple sets of ventilation grooves 309 symmetrically opened on the upper and lower sides, which prevents pests from entering while maintaining air circulation and protecting the healthy growth of plants. The center of the surface of the insect-proof plate 305 is fixedly connected to the connecting rod 307, and the front end of the connecting rod 307 is fixedly connected to the handle 306, which makes it easy to open or close the insect-proof structure, improving the ease of operation and human-computer interaction experience.
[0028] During device operation, the observation slot 301 allows operators to observe the growth status of root suckers non-destructively without moving the plants or nutrient soil. The support plate 304 and the second sliding slots 303 on both sides provide sliding tracks for the sunshade plate 302, which can be flexibly adjusted according to the light intensity requirements to control the amount of light entering the device. The fastening plate 308 is installed at both ends of the cultivation frame 1 to improve the overall sealing and structural stability of the device. The insect-proof plate 305 connected to the front end of the fastening plate 308 achieves the dual functions of ventilation and insect prevention through the symmetrically arranged ventilation slots 309, preventing pests from entering while maintaining air circulation. The connecting rod 307 located in the center of the insect-proof plate 305 is connected to the handle 306, which makes it easy for the operator to quickly open or close the entire protective structure, improving ease of use and operational efficiency.
[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
