    A plant nutrient ring and a tea plant fertilization process using the plant nutrient ring
    Technical part
    The invention belongs to the technical field of tea plant planting, in particular to a plant nutrient ring and a tea plant fertilization method using the plant nutrient ring.
    Background technology
    In order to reduce artificial consumption and increase the slow release of nutrients, the nutrients from the fertilizer are made into a rod-like structure called the nutrient rod. Nutrient stick can be made for a single type of fertilizer or for different fertilizers. When the nutrient stick is used, it is inserted near the root of the crop to slow fertilization when the nutrient stick is slowly released. With regard to tea plants, however, the applicability of the above-mentioned nutrient bar is often weak, since tea plants have diffuse fiber roots and the focus is on balanced fertilization. When inserting the nutrient stick into the soil, it is not only easy to destroy the original fragile natural root system of the tea plant, but also the nutrient diffusion and absorption are mainly concentrated in the insertion area of the stick, which is not the soil area around the entire tea plant
    BE2019 / 5186 feeds, which leads to low nutrient availability. For the reasons mentioned above, traditional fertilization methods such as basic fertilizers and top dressing fertilizers are currently still used in soil cultivation, which means that the fertilization of tea plants generally has the problem of high labor intensity and time expenditure, which greatly hinders the spread of the automated management of the tea plantation
    Content of the invention
    An object of the present invention is to overcome the disadvantages of the prior art and to provide a simple, stable and convenient plant nutrient ring which has good nutrient diffusion and can achieve a balanced fertilization effect in tea plants. Another object of the present invention is to provide a tea plant fertilization method using the plant nutrient ring in order to achieve the purpose of simple and effective fertilization of tea plants with high efficiency.
    To solve the above objects, the invention offers the following technical solution:
    The plant nutrient ring includes more than two arcuate branch pipes and the lumen of the branch pipes constitutes a cavity containing fertilizer. The two ends of each branch pipe are arranged with an interface ring for engaging with the neighboring branch pipes to form a circular nutrient ring body by the first and the last End of each branch pipe
    BE2019 / 5186 are connected. The interface ring is provided with an opening and closing valve, which can control the connection or the closing of the lumen of the adjacent branch pipe. The nutrient overflow outlet through the tube wall is located on one side of the nutrient ring body and the nutrient overflow outlet is covered with a nutrient release film. The so-called nutrient overflow outlet consists of more than three groups and is distributed sequentially along the ring surface of the nutrient ring body.
    -shaped hinge structure of the movable adjustment buckle is formed. The movable adjustment buckle consists of two groups and is arranged on both sides of the filter screen. The adjustable adjustment buckles are connected by different horizontal mesh sizes. The opening and closing valve also includes an opening and closing switch for pressing the movable hinge buckle to produce a telescopic effect in a certain direction. The direction of pressure of the opening and closing switch is parallel to the mesh area of the filter screen and perpendicular to the longitudinal direction of the horizontal mesh size in order to enable opening and closing. When the opening and closing switches are pressed, the adjustment buckle can be extruded and stretched so that the adjacent parallel horizontal mesh can move close and away from each other.
    Preferably, the hinge pillar is located at both ends of the horizontal mesh and the axis of the hinge pillar is parallel to the axis of the hinge axis and a waist-shaped hole is at that
    BE2019 / 5186
    Sub-rod body arranged and the longitudinal direction of the waist-shaped hole is parallel to the longitudinal direction of the horizontal mesh, and the hinge column is embedded in the waist-shaped hole and can perform linear guide movements along the longitudinal direction of the waist-shaped hole.
    Preferably, the opening and closing switch comprises a rotary handle arranged on the outer wall of the valve tube, and a gear is arranged coaxially on the rotary shaft of the rotary handle, and the axis of a transition shaft is parallel to the mesh surface of the filter screen and perpendicular to the longitudinal direction of the horizontal mesh size . A rack is arranged along the outer wall of the transition shaft and the rack length is parallel to the axis of the transition shaft. The tooth combing process is formed between the rack and the gear. A push rod is located at an end of the transition shaft that is relatively close to the movable adjustment buckle. There are two push rods and the push rods are axially symmetrical relative to the axis of the transition shaft. One end of one of the two pushrods is attached to the transition shaft and the other end of the pushrod is attached or hinged to the upper sub-bar body of the movable hinge buckle.
    There is preferably an angle between the two pressure rods and the angle is obtuse, and the angle opening, which is formed by two pressure rods, lies in the direction of the filter screen.
    Preferably, the filter screen consists of vertical mesh sizes, which are arranged at regular intervals from one another, and
    BE2019 / 5186 vertical mesh size and the horizontal mesh size together form a square lattice structure.
    The diameter of the branch pipe is preferably 5-8 cm, the inside diameter of the nutrient ring body is 80-100 cm and the diameter of the nutrient overflow outlet is 3-5 cm.
    Preferably, the two pipe ends of the branch pipe are each arranged with the sub-connections of the external thread of the interface ring and the nut connections of the internal thread, which rotate along the axis of the branch pipe, so that the two adjacent pipe ends of the branch pipe are screwed together on the interface ring by the thread adaptation between sub-connections and nut connections can be.
    A tea plant fertilization method using the plant nutrient ring is preferably characterized in that the method comprises the following steps:
    1) . According to the current nutrient requirement and the proportion of tea plant growth, the designated liquid fertilizer is added to the branch pipe, and the nutrient ring body is formed by the first and the last end of each branch pipe being connected to one another by the interface ring.
    2). By adjusting the opening and closing valve and balancing the amount of liquid fertilizer in each branch pipe until the liquid fertilizer content in each branch pipe is the same, and the opening and closing valve is closed so that each branch pipe is isolated from each other.
    BE2019 / 5186
    3). A ring pit for plant nutrient ring is dug out around the main stem of the tea plant. The depth of the ring pit is 10 to 15 cm, and the axis of the ring pit is coaxial with the main stem of the tea plant. The plant nutrient ring is placed in the ring pit so that the plant nutrient ring is placed around the main stem of the tea plant and is then covered with soil and the nutrient overflow outlet is always held down.
    The phytonutrient ring is preferably removed every 1-2 months to replenish liquid fertilizer. One of the interface rings is arbitrarily disassembled during refilling, and excess water in the branch pipe is released by opening and closing the opening and closing valve, and then new liquid fertilizer is injected again. Burying the plant nutrient ring is completed by steps 1), 2) and 3) described above.
    The advantageous effects of the present invention are:
    1). The traditional design chains of the straight rod-shaped plant nutrient ring are removed and a new design idea of a ring-shaped nutrient rod is adopted. The plant nutrient ring is a ring structure that can provide the same nutrient concentration for all soil areas around the tea plant better and more evenly. It not only avoids damage to the root and stem of the tea plant, but also improves the absorption of minerals by the tea plant. The
    BE2019 / 5186
    Not only can nutrient release film on the nutrient overflow outlet control the nutrient flow history and additional fertilizer loss, but it can also meet the normal needs of tea plant growth so that the roots and stems of tea plants form a certain free nutrient space directly with the nutrient ring itself, and the nutrients according to needs gradually release the physiological growth rhythm of the tea plants. It is even more important that the interface ring also integrates the structure of the opening and closing valve on its basis as a joint component. When liquid fertilizer is manually injected into the plant nutrient ring, there is inevitably an imbalance in the amount of liquid fertilizer in each branch pipe, which obviously has an adverse effect on the normal growth of tea plants that require balanced fertilization. By designing the opening and closing valve, the amount of liquid fertilizer in each branch pipe is roughly distributed after the injection of liquid fertilizer into each branch pipe is completed according to the characteristics of each branch pipe for equal division. Then the respective branch pipe is connected, and the liquid fertilizer in each branch pipe is rebalanced twice by opening and closing the opening and closing valve, so that the goal of balanced fertilization can be achieved in two steps and the unbalanced problem can be effectively eliminated. The efficiency of use of nutrient fertilizers is significantly improved.
    BE2019 / 5186
    2). The structure of the opening and closing valve is also a focus of the present invention. The traditional opening and closing valve is based on opening and closing the valve insert in order to realize the opening and closing of the valve.
    Of course, the structure can also be used directly in the present invention. The invention designs a separate opening and closing valve structure that relies on the gear and rack movement of the twist grip and the transition shaft, thereby controlling the transition shaft when the twist grip rotates to produce the axial movement. The axial displacement of the transition shaft will drive the push rod to produce a lifting motion and then push the movable adjustment buckle to create an expansion and pushing motion. Since the movable adjustment buckle is equipped with a horizontal mesh size, as soon as the movable adjustment buckle executes an expansion movement, an approach movement and exit movements of the horizontal mesh width are also generated. If the
    Approximate movement of the horizontal mesh is near the limit, it can close to close to close the valve tube cavity. In contrast, when the horizontal mesh is separated, the space between them forms the flow space of circulable liquid fertilizer to filter out impurities, which is very practical.
    3). The mode of interaction between the horizontal mesh and the secondary rod body can be varied, or
    BE2019 / 5186 the horizontal mesh size itself can be a retractable structure, e.g. the telescopic rod, etc. If the movable adjusting buckle produces the telescopic effect, it can thus adapt to the change in distance of the corresponding auxiliary rod body, which is caused by the actuation of the two movable adjusting buckles. Or, the horizontal mesh size can connect the side bar body through elastic ribs, etc., so that it can depend on the elasticity of the elastic ribs to achieve the telescopic action of the movable adjustment buckle, and the horizontal mesh size can quickly correspond with each other and generate an approaching and exiting movement. Even the horizontal mesh size can be right in the middle of the
    Auxiliary rod body are articulated. Regardless of how the subbar body moves at this position, it has no effect on horizontal mesh size. The invention preferably opens a waist-shaped hole on the sub-rod body, thereby interacting with the slide guide rail between the hinge pillar at the horizontal mesh and the waist-shaped hole. Even if the distance between the two auxiliary rod bodies at the two ends of the horizontal mesh size changes due to the action of the movable adjusting buckle, the horizontal mesh size can compensate for the change by moving the corresponding waist-shaped hole, thereby ensuring the response of the horizontal mesh size. Due to the above structure of the invention, the arrangement of the horizontal mesh size is not limited to any one
    BE2019 / 5186
    Limited position, installation is more flexible and feasibility is stronger.
    4). In practice, the vertical filter screen is used instead of the tightly packed small mesh filter screen. The reasons for this are as follows: On the one hand, the filter screen uses the vertical mesh size and the horizontal mesh size to form a square lattice structure, which can also achieve the filtering of impurities in liquid fertilizer and the flow of liquid fertilizer. On the other hand, the filter screen uses the vertical mesh size, which makes subsequent cleaning very convenient. N After pulling out the filter sieve and wiping it directly along the vertical mesh, all impurities adhering to the mesh surface of the filter sieve can be completely removed, thereby avoiding the difficult mesh cleaning of the tightly packed small mesh filter sieve.
    5). When the plant nutrient ring combination is sealed, it must be buried in the ground around the tea plant in a circle with a depth of 10-15 cm. After the plant nutrient ring is buried in the ground for 7 to 15 days, the nutrient segregation begins to overflow through the nutrient release film at the nutrient overflow outlet of the plant nutrient ring, then the nutrients are released to the rhizosphere floor of the tea plant according to the needs of the physiological growth rhythm of the tea plant. The tea root system can effectively absorb the minerals released and use them efficiently. Plant nutrient rings must be removed every 1 to 2 months and then new liquid fertilizer will be added
    BE2019 / 5186 injected to ensure continuity of fertilization. The fertilization steps are extremely convenient and simple, and the application threshold is very low.

    Specific embodiments
    For ease of understanding, the specific structure and operation of the present invention are described herein in connection with Figure 1-4.
    The specific structure of the plant nutrient ring according to the present invention is shown in Figure 1-2. The main components of the plant nutrient ring comprise a branch pipe 10 and an interface ring 20. The two pipe ends of the branch pipe 10 are each arranged with the sub-connections of the external thread of the interface ring 20 and the nut connections of the internal thread. In use, the adjacent pipe ends of the branch pipe 10 are screwed to one another by thread adaptation, whereby the rapid connection of the adjacent branch pipe 10 is realized.
    Based on the above structure, the embodiment shown in Figure 1-2 provides two sets of branch pipes 10 to connect the head and tail to form a circular vegetative ring. The first and last ends of the branch pipes are connected to form a circular plant nutrient ring. As shown in Figure 3, the filter screen 40 of vertical mesh size 41 is arranged at a fixed distance and the cross-regulation network of horizontal mesh size 213 is arranged in the interface ring 20 with the adjustable distance. In use, the gear and rack movements of the rotary handle 214 and the transition shaft 215 are instructed so that the
    BE2019 / 5186
    Transition shaft 215 can be controlled as the handle 214 rotates to produce the axial movement. The axial displacement of the transition shaft 215 will drive the push rod 216 to produce a lifting motion, and then push the movable adjustment buckle 212 to create an expansion and pushing motion. Since the movable adjustment buckle 212 is equipped with a horizontal mesh size 213, and the movable guide rail at both ends of the horizontal mesh size 213, as shown in Figure 4, cooperate with the corresponding auxiliary rod body 212a as soon as the movable adjustment buckle 212 executes a stretching movement creates an approach and exit movement of the horizontal mesh 213. When the horizontal mesh 213 approach movement is near the boundary, it may close to close to close the valve tube cavity 211. In contrast, when the horizontal mesh 213 are separated, the space between them forms the flow space of circulable liquid fertilizer to filter out impurities, which is very practical.
    In particular, the actual use of the present invention, as indicated in Figure 1, is as follows:
    First, the circular plant nutrient ring is divided into two groups of semicircular branch pipes 10. Liquid fertilizer is added depending on the nutrient requirements and the proportion of tea plant growth. Then the two are semicircular
    BE2019 / 5186
    Branch pipes 10 are screwed through the interface ring 20. Since the opening and closing valve 21, which consists of a filter screen 40 and a cross-regulating network within the interface ring 20, the interface ring 20 can contaminate the
    Get the plant nutrient ring, filter it out effectively and at the same time ensure the efficient flow of nutrients and water. Therefore, the amount of liquid fertilizer in each of the branch pipes 10 can be rebalanced by opening and closing the opening and closing valve 21 before burying to ensure that liquid fertilizer can be evenly distributed around the plant nutrient ring. When burying the circular plant nutrient ring, it is necessary to bury it in a circle with a depth of 10-15 cm around the tea plant. After the plant nutrient ring is buried in the ground for 7 to 15 days, the nutrient segregation begins to overflow through nutrient release film 31 at the nutrient overflow outlet 30 of the plant nutrient ring, then the nutrients are released onto the rhizosphere floor of the tea plant according to the needs of the physiological growth rhythm of the tea plant.
    The tea root system can effectively absorb the minerals released and use them efficiently.
