Description

Technical Field

[0001] This utility model relates to the field of agronomic equipment technology, specifically to a soilless cultivation root-controlling tidal pot that promotes early flower bud differentiation. Background Technology

[0002] In the field of potted fruit and vegetable cultivation, traditional potted containers have a relatively simple structural design, and the pot walls usually lack special construction, resulting in poor soil aeration. When overwatering occurs, excess water cannot drain in time, easily causing waterlogging, which in turn leads to problems such as root hypoxia and rot, affecting the healthy growth of the plant.

[0003] Addressing the shortcomings of traditional potted plants, existing root-control pots are a type of cultivation pot with good air and water permeability, primarily used to control the growth of the taproot and promote the development of lateral roots. Root-control pots typically have ventilation holes or grooves on the sides to increase aeration, prevent waterlogging at the bottom, and guide the directional growth of the taproot. Furthermore, the principle of air pruning promotes the growth of new roots in the center of the root system, increasing the number of roots. When roots grow out of the pot, the air acts as a "root pruning" mechanism, stimulating the sprouting of more lateral roots, thus making the root system more developed.

[0004] As mentioned above, existing root-control pots typically incorporate numerous ventilation holes, grooves, or slits to achieve root control. When the ambient temperature is high and the air humidity is low, moisture in the soil within the pot evaporates rapidly into the external environment through these pores. Furthermore, some root-control pots have large and numerous drainage holes at the bottom. After watering, excess water drains quickly, along with a significant amount of water that could be absorbed and utilized by the plant roots, making it difficult to maintain soil moisture at a level suitable for plant growth. Especially during hot and dry seasons, even with frequent watering, water still evaporates rapidly, failing to meet the plant's continuous water requirements. Summary of the Invention

[0005] Based on the above problems, the purpose of this utility model is to provide a pot structure that can effectively control plant root growth, ensure plant water supply, and improve cultivation quality.

[0006] To achieve the above objectives, this utility model provides a soilless cultivation root-controlling tide pot for promoting early flower bud differentiation, comprising an outer pot and an inner pot.

[0007] The outer basin is provided with a placement cavity for accommodating the inner basin. The bottom of the placement cavity is provided with a drain outlet, and the edge of the drain outlet is provided with an annular barrier. The outer basin is configured to support the inner basin using the annular barrier, and to separate a water storage cavity at the bottom of the placement cavity using the annular barrier.

[0008] The inner basin is installed in the placement cavity, and the inner basin is provided with a planting cavity. The bottom of the inner basin is provided with a limiting frame. The limiting frame is sleeved on the outside of the annular enclosure to form a radial limit on the inner basin and to give the inner basin a rotational degree of freedom to rotate around its own axis. Openings are provided on the bottom wall and side wall of the inner basin.

[0009] The inner pot is configured to connect the planting cavity and the placement cavity through an opening, allowing the crop roots in the planting cavity to grow into the placement cavity through the opening, and the rotational movement of the inner pot relative to the outer pot to cut the crop roots.

[0010] This invention proposes a hydroponic root-controlling tide pot for promoting early flower bud differentiation. When used, the inner pot is rotated periodically according to the crop's agronomical requirements. The rotation stretches the crop's roots, causing lateral and downward roots to break. This restricts nitrogen absorption, lowering the nitrogen level in the plant and increasing the C / N ratio. Through this physical method, increased crop yield is achieved in hydroponic root-controlling tide pots that promote early flower bud differentiation. Taking strawberries as an example, after the root pruning operation, the strawberry seedlings shift from vegetative growth to reproductive growth within 2-3 days, promoting earlier flower bud differentiation and thus increasing yield.

[0011] Preferably, the limiting frame is a ring frame adapted to the ring-shaped enclosure, and the inner diameter of the ring frame and the outer diameter of the ring-shaped enclosure are in clearance fit.

[0012] Preferably, the inner basin and the outer basin are arranged coaxially.

[0013] Preferably, an annular channel for filling planting substrate is provided between the inner and outer pots.

[0014] Preferably, the width of the annular channel is 3cm-5cm.

[0015] Preferably, the opening includes a first circular hole and a second circular hole, the first circular hole being located on the bottom wall of the inner basin and the second circular hole being located on the side wall of the inner basin.

[0016] Preferably, the first circular holes are arranged in a multi-layered circular array on the bottom wall of the inner basin.

[0017] Preferably, multiple second circular holes are arranged in a linear array on the side wall along the axial direction of the inner basin to form a side outlet unit, and multiple side outlet units are arranged in a circular array on the side wall of the inner basin around the axis of the inner basin.

[0018] Preferably, the diameters of the first and second round holes are 3mm-5mm.

[0019] Compared with existing technologies, the soilless cultivation root-controlling tidal pot provided by this utility model, which promotes early flower bud differentiation, has the following substantial features and advancements: This soilless cultivation root-controlling tidal pot, through the rotational movement of the inner pot relative to the outer pot, cuts the crop root system, breaking the apical dominance of the root system, prompting the root system to produce more lateral roots and fibrous roots, constructing a more developed root network, significantly improving the root system's absorption efficiency of water and fertilizer. Simultaneously, it stimulates new root growth, promotes flower bud differentiation, and thus increases yield. Furthermore, the water storage chamber and planting chamber are connected through openings in the inner pot, which facilitates the formation of a tidal irrigation mode, ensuring water supply, allowing the plant roots to absorb water and nutrients as needed, reducing water evaporation and fertilizer loss, and improving water and fertilizer utilization.

[0026] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0027] To address the shortcomings of existing root control pots, this invention proposes a soilless root control tidal pot that promotes early flower bud differentiation, aiming to effectively control plant root growth, ensure plant water supply, and improve cultivation quality.

[0028] This invention presents a hydroponic root-controlling tidal pot for promoting early flower bud differentiation. Through the cooperation of an outer pot with a ring-shaped enclosure and an inner pot with a limiting frame, the inner pot rotates and cuts the root system to optimize its structure. Simultaneously, the openings in the inner pot create tidal irrigation, precisely controlling the water level and preventing excessive evaporation and loss, effectively maintaining humidity and meeting the crop's water requirements. Furthermore, the rotational movement of the inner pot relative to the outer pot cuts the crop's root system, breaking apical dominance and encouraging the growth of more lateral and fibrous roots, thus constructing a more developed root network. This significantly improves the root system's efficiency in absorbing water and fertilizer, while simultaneously stimulating new root growth and promoting flower bud differentiation, ultimately leading to increased yield.

[0029] like Figure 1 As shown, a hydroponic root-controlling tide pot for promoting early flower bud differentiation includes an outer pot 1 and an inner pot 2. (As shown...) Figure 2 As shown, the outer basin 1 has a placement cavity 3 for accommodating the inner basin 2. A drain outlet is located at the bottom of the placement cavity 3, and an annular barrier 4 is provided along the edge of the drain outlet. Figure 5 As shown, the outer basin 1 is configured to support the inner basin 2 using an annular enclosure 4, and the annular enclosure 4 is used to separate a water storage chamber 5 at the bottom of the placement cavity 3.

[0030] like Figure 2 As shown, the inner basin 2 is installed inside the placement cavity 3. The inner basin 2 contains a planting cavity 6. A limiting frame 7 is provided at the bottom of the inner basin 2. The limiting frame 7 is fitted onto the outside of the annular enclosure 4, providing radial limitation for the inner basin 2 and allowing the inner basin 2 to rotate freely around its own axis. Openings are provided on both the bottom and side walls of the inner basin 2.

[0031] The inner pot 2 is configured to connect the planting cavity 6 and the placement cavity 3 through an opening, so that the crop roots in the planting cavity 6 can grow into the placement cavity 3 through the opening, and the rotational movement of the inner pot 2 relative to the outer pot 1 can cut the crop roots.

[0032] Roots, as vital organs of plants, play a crucial role in absorbing, transporting, synthesizing, and retaining water. Based on literature and planting experiments, root pruning can promote flower bud differentiation. The principle is that after root pruning, some lateral roots and root hairs are severed, restricting the absorption of nitrogen fertilizer by the root system. This reduces the nitrogen level in the plant, increases the C / N ratio, and shifts the crop from vegetative growth to reproductive growth, thus accelerating flower bud differentiation.

[0033] In actual production, taking strawberry cultivation as an example, the timing of root pruning must be considered in conjunction with local temperature and sunshine conditions. Generally, the optimal time for root pruning is 14 days before the strawberry transitions from vegetative to reproductive growth and flower bud differentiation begins, when the average daily temperature is below 20℃ and the sunshine duration is below 12 hours. Application studies on strawberries have shown that the stem diameter of seedlings treated with different root pruning times is significantly higher than that of the control, and the earlier the root pruning, the larger the stem diameter. Root pruning can increase the root and stem-leaf biomass and root-to-shoot ratio of strawberry plants. Root pruning can promote uniform and robust plants and earlier flower bud differentiation, significantly increasing yield. Because root pruning alters the growth and development pattern of a certain plant organ, it improves the absorption function of the root system, promotes the absorption of water and nutrients by the roots, thereby increasing the crop's photosynthesis and promoting the improvement of indicators such as biomass and root-to-shoot ratio.

[0034] like Figure 2 As shown, the limiting frame 7 is a ring frame adapted to the ring-shaped enclosure 4, and the inner diameter of the ring frame and the outer diameter of the ring-shaped enclosure 4 are in clearance fit. This clearance fit allows the inner pot 2 to have flexible rotational freedom within the placement cavity 3. When the crop roots grow and touch the wall of the inner pot 2, the rotational movement of the inner pot 2 relative to the outer pot 1 can proceed smoothly, allowing for timely cutting of excessively long roots, effectively controlling taproot growth, promoting the sprouting of numerous lateral roots, forming a more developed root network, and providing a good root environment for plant growth.

[0035] like Figure 3 As shown, the inner pot 2 and the outer pot 1 are arranged coaxially. This ensures that the distance between the inner pot 2 and the annular surrounding wall 4 of the outer pot 1 remains consistent throughout the rotation process, guaranteeing a uniform distribution of cutting forces on the crop roots during growth. This avoids situations where some roots are over-cut while others are under-cut due to positional deviations, promoting uniform root growth within the planting cavity 6, forming a well-developed and symmetrical root structure, enhancing the overall stability and resistance of the plant, and maximizing the root control advantages of the soilless cultivation root-controlling tide pot in promoting early flower bud differentiation.

[0036] like Figure 3 As shown, an annular channel 10 for filling planting substrate is provided between the inner pot 2 and the outer pot 1. The annular channel 10 provides additional growth space for crop roots, allowing them to continue extending and expanding within the substrate after penetrating the opening in the inner pot 2. Simultaneously, the planting substrate filling the annular channel 10 effectively absorbs and stores water and nutrients during tidal irrigation. When the water level in the outer pot 1 drops, the water and fertilizer stored in the substrate of the annular channel 10 are slowly released, continuously providing nutrients to the roots and preventing the problem of insufficient nutrient absorption due to rapid water loss after a single irrigation.

[0037] According to some preferred embodiments of this utility model, the width of the annular channel 10 is 3cm-5cm. This width range of the annular channel 10, while satisfying the basic functions, allows for a more compact and reasonable layout of the surrounding space of the hydroponic root-controlling tide pot that promotes early flower bud differentiation.

[0038] like Figure 2 As shown, the opening includes a first circular hole 8 and a second circular hole 9. The first circular hole 8 is located on the bottom wall of the inner pot 2, and the second circular hole 9 is located on the side wall of the inner pot 2. Thus, the first circular hole 8 on the bottom wall guides the roots to grow downwards, encouraging deeper root penetration and stronger grip on the ground; the second circular hole 9 on the side wall guides the roots to expand laterally, forming a wider root network. The combination of these two features breaks the single growth direction of the roots, allowing them to grow three-dimensionally within the planting cavity 6, preventing root tangling and promoting the abundant sprouting of lateral and fibrous roots. This constructs a well-developed and balanced root system, providing a solid foundation for the plant to absorb water and nutrients.

[0039] like Figure 3 As shown, the first circular holes 8 are arranged in a multi-layered circular array on the bottom wall of the inner pot 2. This multi-layered circular array layout guides the roots to grow in a uniform and orderly direction at the bottom of the planting cavity 6. Each first circular hole 8 serves as a "guide point" for the roots to extend downwards, encouraging them to grow dispersedly within the bottom space and preventing excessive concentration of roots in a particular area, thus preventing root entanglement.

[0040] like Figure 4 As shown, multiple second circular holes 9 are arranged in a linear array on the side wall along the axial direction of the inner basin 2 to form a side outlet unit. Multiple side outlet units are arranged in a circular array on the side wall of the inner basin 2 around the axis of the inner basin 2.

[0041] Multiple second circular holes 9 are arranged linearly along the axis of the inner pot 2 to form side-ejection units, and then arranged in a circular array around the axis of the inner pot 2 to construct a three-dimensional network. This arrangement guides the roots to grow in an orderly manner in both the horizontal and vertical dimensions, allowing the roots to be distributed radially in a three-dimensional manner around the sidewalls of the planting cavity 6, breaking the disordered growth pattern of the roots and preventing them from tangling or clumping together. By precisely controlling the growth direction and spatial distribution of the roots, a more developed and rational three-dimensional structure is formed, enhancing the plant's ability to absorb water and fertilizer and its overall stability.

[0042] Preferably, the diameter of the first circular hole 8 and the second circular hole 9 is 3mm-5mm.

[0043] This utility model proposes a hydroponic root-controlling tide pot for promoting early flower bud differentiation. When used in conjunction with a water storage tank and connecting water pipes, it enables a simple siphon-type tide irrigation method for crops. The water storage tank is placed above the hydroponic root-controlling tide pot and connected to the water storage chamber 5 via the connecting water pipe. The valve on the connecting water pipe is opened, allowing water from the storage tank to flow into the water storage chamber 5 until the water level reaches the set height. The valve is then closed, stopping the water inflow and maintaining the soaking time. The valve is then opened again, using the siphon principle to pump the water in the water storage chamber 5 back to the storage tank, completing the receding tide. By adjusting the height of the storage tank or the length of the connecting water pipe, the water flow rate and soaking time can be controlled, simulating an intermittent tide irrigation method to achieve efficient water and fertilizer management.

[0044] Furthermore, according to the agronomic requirements of crop growth, the inner pot 2 is rotated periodically. The rotation stretches the crop roots, causing lateral and downward roots to break. This restricts the absorption of nitrogen fertilizer by the crop roots, lowering the nitrogen level in the plant and increasing the C / N ratio. Through this physical method, increased crop yield is achieved in soilless cultivation with root-controlling tide pots that promote earlier flower bud differentiation. Compared to traditional root-control pots, this soilless cultivation root-controlling tide pot for promoting earlier flower bud differentiation features manually adjustable root control technology, a more pronounced tide effect, and a gentler and longer-lasting water retention effect.

[0045] The outer pot 1 and inner pot 2 of the hydroponic root-controlling tide pot for promoting early flower bud differentiation proposed in this embodiment of the invention can both be made of PE (polyethylene), which has the characteristics of corrosion resistance, good ductility, and long service life. The dimensions of the outer pot 1 and inner pot 2 can be designed according to the planting needs of different potted crops, for example, the depth and drainage design of the pot can be matched.

[0046] This utility model is not limited to the specific technical solutions described in the above embodiments. Besides the above embodiments, this utility model may have other implementation methods. For those skilled in the art, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
