Description

Technical Field

[0001] The invention belongs to the technical field of agriculture and forestry cultivation, and in particular relates to a forest tree seedling cultivation system and a seedling cultivation method. Background Art

[0002] Seedling cultivation is an effective means of expanding reproduction, which usually includes sowing, cuttings, high-pressure propagation, etc. Cuttings are also a widely used seedling cultivation method, which usually requires the use of containers filled with substrates for cuttings. In a common breeding scenario, the container in which the plant seedlings are cultivated will be placed directly on a layer of substrate or on the soil surface. After the roots of the plant seedlings grow into the substrate or soil, unified watering, fertilization and other management will be carried out. The advantage of this is that it ensures that the root system of the plant is sufficiently developed to support the development of the plant, and unified watering and fertilization through the substrate or soil can also improve the efficiency of management, and can also avoid problems such as water accumulation and root suffocation caused by container cultivation that are not conducive to plant growth. However, when using this method to remove seedlings, it is often faced with the problem that the root system is too developed, and the roots that penetrate into the substrate or soil are too many or too thick, making it difficult to separate the roots and difficult to remove the container from the substrate or soil.

[0036] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0037] Example

[0038] Figure 1 What is shown is a schematic diagram of the structure of the cultivation system. The forest seedling cultivation system described in the present application includes a substrate layer 100 arranged at the bottom layer, a support frame 200 arranged on the substrate layer 100, and a container 300 for cultivating plants placed on the support frame 200.

[0039] The substrate layer 100 is a medium for plant cultivation, which can provide support for plants and retain moisture and nutrients to facilitate the growth of plant roots; typically the components of the substrate layer 100 include a mixture of one or more components of vermiculite, perlite, peat moss, coconut bran, polymer matrix (such as rock wool), crushed bark or sawdust, gravel or sand.

[0040] Figure 2 What is shown is a schematic diagram of the structure of the support frame 200, which includes a plate 1 210 and a plate 220 arranged in an angular shape, a plurality of through holes 211 are arranged on the plate 1 210, and a plate 3 230 attached to the plate 1 210 is also arranged at the connection between the plate 1 210 and the plate 2 220, and the plate 3 230 can move relative to the plate 1 210 to produce a shear effect.

[0041] Figure 3 What is shown is a schematic diagram of the structure of a container 300, the top of which is open to facilitate filling of a cultivation substrate and cultivation of seedlings. The container 300 has a bottom 310 and a side wall 320 connected to the bottom 310. The bottom 310 has a second through hole 311 to facilitate the roots of the seedlings cultivated in the container 300 to grow downward through the second through hole 311 into the substrate layer 100 at the bottom. In addition, the side wall 320 can also be provided with side holes 321 as needed to facilitate ventilation of the roots.

[0042] Combination Figures 1 to 3 As shown, an angular structure is formed between the plate 1 210 and the plate 2 220, and correspondingly, a protrusion with a slope 110 is also formed on the surface of the matrix layer 100. Before cultivation, the support frame 200 is placed on the matrix layer 100, and the angular structure of the support frame 200 is placed corresponding to the slope 110. The container 300 with seedlings is placed on the plate 1 210 of the support frame 200, and the seedlings cultivated in the container 300 are normally maintained so that the roots of the seedlings penetrate into the matrix layer 100 below, so as to facilitate unified management and maintenance of the seedlings.

[0043] In the present application, although the surface of the matrix layer 100 can be trimmed to form a protrusion with a slope 110, the protrusion with the slope 110 is still the matrix layer 100, which is not stable and is easy to collapse or deform in the later maintenance. Therefore, the support frame 200 is placed on the matrix layer 100 to provide a stable slope for placing the container 300, avoiding the slope 110 itself from directly supporting the container 300. At the same time, the adaptive shape of the support frame 200 plays the role of a cage to maintain the protrusion state for a long time. On the other hand, due to the adaptive The angular structure of the plate 1 210 and the plate 2 220 arranged on the slope 110 divides the bearing surface for placing the container 300 from the original whole plane into mutually spaced strips without almost changing the overall placement area, which further facilitates the arrangement of the plate 3 230 and the plate 1 210 so that the plate 3 230 and the plate 1 210 can move relative to each other when needed, forming a shearing effect, thereby cutting off the roots that penetrate into the matrix layer 100 through the through hole 2 311, thereby facilitating the separation of the container 300 and the matrix layer 100.

[0044] On the other hand, since the roots are directly cut off from plate 1 210, the excised roots will remain in the protrusions and the substrate layer 100 below. When cleaning before subsequent cultivation, the protrusions can be directly cleaned by pushing and leveling to expose the remaining roots, thereby facilitating the cleaning of the remaining roots. In the traditional planar cultivation method, the remaining roots are below the plane and need to be cleaned by digging.

[0045] In the present application, the bottom 310 of the container 300 is optionally set to be a slope. The slope state of the bottom 310 described in the present application is relative to the opening surface of the container 300, that is, the state in which the bottom and the opening of the traditional container 300 are parallel to each other is changed, and the inclination angle of the slope of the bottom 310 is the same as the inclination angle of the slope 110, so that when the container 300 is placed on the board 210, it can be adjusted to the level of the opening of the container 300, and the main branches of the plants and seedlings cultivated in the container 300 maintain upright growth, avoiding deformation of the plants and seedlings due to inclined growth.

[0046] Figure 4 What is shown is a schematic diagram of the structure of plate three 230, on which plate three 230 is provided with through hole three 231, which can correspond to through hole one 211 in a certain state, thereby exposing the bottom matrix layer 100 to facilitate the roots to enter the matrix layer 100 through through holes one 211 and through holes three 231.

[0047] Plate three 230 is also provided with a spring piece 232 protruding from the plane where the plate body is located. The thickness of the spring piece 232 is smaller than the thickness of plate three 230 so that the spring piece 232 can deform and shrink toward the inside of plate three 230. The spring piece 232 is used to cooperate with plate one 210 to limit the position of plate three 230 so that through hole three 231 corresponds to through hole one 211.

[0048] Figure 5 What is shown is a schematic diagram of the cooperation state of plate three 230 and plate one 210. In the use state, plate one 210 is installed in contact with the lower surface of plate three 230, so that the upper surface of plate three 230 can place the container 300 without obstacle, and plate three 230 can also move relative to plate one 210 without obstacle; in addition, at least a part of the edge of through hole three 231 is a beveled surface one 233, so that when plate three 230 moves relative to plate one 210 along direction A, the cutting direction of the beveled surface one 233 is the same as the moving direction of plate three 230, and the beveled surface one 233 cooperates with plate one 210 to form a shearing effect on the root system, thereby quickly cutting off all roots growing into the matrix layer 100.

[0049] Further integration Figure 2 The third plate 230 is inserted through the connection between the first plate 210 and the second plate 220, and a portion of the third plate 230 is still exposed to the outside of the first plate 210. The exposed portion can be pushed into the support frame 200 by external application, thereby forming Figure 5 The moving status of middle plate three 230.

[0050] Figure 6 What is shown is a schematic diagram of the assembly structure of plate three 230, which is arranged on the bottom surface of plate one 210 (i.e., the side in contact with the matrix layer 100). Two symmetrically arranged L-shaped ribs 212 are arranged at the bottom of plate one 210. The L-shaped ribs 212 and plate one 210 form a groove for accommodating the sliding of plate three 230. The L-shaped ribs 212 have a notch 213, and the notch 213 corresponds to accommodating the spring piece 232. When plate three 230 is not subjected to external force, the protruding structure of the spring piece 232 will abut against the edge of the notch 213, limiting the movement of plate three 230 along direction A to maintain the corresponding state of through hole three 231 and through hole one 211. Once external force is applied to plate three 230, the spring piece 232 is compressed and deformed and slides into the L-shaped rib 212.

[0051] See also Figure 2The support frame 200 also has a fourth plate 240 connected to the second plate 220. The fourth plate 240 is arranged on a side away from the first plate 210, and the fourth plate 240 is arranged horizontally when in use to fit the surface of the substrate layer 100. The contact area between the fourth plate 240 and the substrate layer 100 is increased, so that part of the gravity exerted on the container 300 is shared by the fourth plate 240, avoiding the problem of the support frame 200 sinking due to the large pressure formed by the edge of the second plate 220 directly contacting the substrate layer 100, and further avoiding the problem of the slope 110 collapsing.

[0052] In another embodiment, the container 300 is also provided with a gripping structure for easy lifting, see Figure 7 An outer pull ring 330 is provided on the side wall of the container 300. One way to form the outer pull ring 330 is to directly open a hole on the side wall of the container 300, so that the upper part of the opening forms the outer pull ring 330 as a part of the container 300. Alternatively, an additional outer pull ring 330 can be directly formed on the edge of the container 300, that is, the outer pull ring 330 is higher than the edge of the container 300.

[0053] by Figure 7 The outer pull ring 330 shown in FIG. Figure 8 Shows Figure 7 In the enlarged view of point B in the middle, the outer pull ring 330 is set at a position with the maximum vertical distance from the edge of the bottom 310, that is, the outer pull ring 330 is set on the lower side of the slope where the bottom 310 is located. The purpose of such design is to keep the container 300 upright as much as possible during the process of lifting and moving the container 300. Since the bottom 310 of the container 300 is a sloped design structure, the center of gravity is more inclined to the lower side of the bottom 310 during the lifting process, and the outer pull ring 330 is just set on the lower side of the bottom 310, so that the vertical distance between the direction of the force applied to the outer pull ring 330 and the center of gravity of the container 300 is smaller, and then the degree of deflection of the container 300 during the lifting process will also be smaller, which is conducive to keeping the container 300 upright and preventing the matrix inside it from sliding out due to excessive tilting of the container 300.

[0054] Furthermore, a movable side panel 340 is provided on the outer wall of the container 300, and the bottom of the side panel 340 has two protrusions 341, and the distance between the two protrusions 341 is the same as the distance between adjacent through holes 211. The top of the side panel 340 is connected to a swing plate 342, and the other end of the swing plate 342 is connected to an inner pull ring 343. A connecting piece 344 is provided in the middle of the swing plate 342, and the other end of the connecting piece 344 is connected to the container 300.

[0055] Also, see Fig. 9The side plate 340 is connected to the side wall 320 of the container 300 by a second connecting piece 345. The second connecting piece 345 and the first connecting piece 344 maintain the same inclination angle, and the inclination state of the first connecting piece 344 is opposite to the inclination state of the bottom 310 of the container 300. Figure 8 As shown in the example, the bottom 310 of the container 300 is lower on the left and higher on the right, and the second connecting piece 345 and the first connecting piece 344 are higher on the left and lower on the right.

[0056] Based on the holding structure recorded above, during the seedling raising process, the staff needs to lift the container 300 with the tree seedlings through the outer pull ring 330 and place it on the support frame 200, and in the process of lifting the container 300, the hand acts on the inner pull ring 343 at the same time. Under the influence of the weight of the container 300 itself, the inner pull ring 343 will move upward and approach the outer pull ring 330 until the two are fitted together. During this process, the swing plate 342 swings at the connection point of the connecting piece 1 344 to press the side plate 340 downward, and at the same time, under the synergistic effect of the connecting piece 2 345, the side plate 340 moves downward as a whole and the protrusion 341 extends beyond the edge of the bottom 310. When the container 300 is placed on the support frame 200, the protrusion 341 is inserted into the through hole 1 211 accordingly.

[0057] When the through holes 211 on the support frame 200 are arranged as a rectangular array along the length and width directions, it can be ensured that the container 300 maintains a relatively accurate and consistent uprightness after being placed on the support frame 200. This is because among the through holes 211 in the rectangular array along the length and width directions, only the distance between two adjacent through holes 211 in the length direction and the distance between two adjacent through holes 211 in the width direction are equal to the distance between the two protrusions 341, and the distance between two oblique through holes 211 is greater than the distance between the two protrusions 341. Therefore, when placing the container 300, the tilted state of the container 300 is very obvious when the protrusions 341 are correspondingly inserted into the two adjacent through holes 211 in the width direction, and the state of the hand may be adjusted to a larger angle when placing it, so the upright placement of the container 300 can be achieved more conveniently.

[0058] Fig.10 The figure shows the arrangement of the matrix layer 100 and the support frame 200 in another embodiment. The protrusions with slopes 110 on the surface of the matrix layer 100 are arranged in groups, each group has two symmetrical slopes 110, and the high points of the two slopes 110 are close to each other. The support frame 200 is arranged to have a shape corresponding to the slopes 110, that is, the support frame 200 includes symmetrically arranged plates 1 210 and 220, and the plates 1 210 and 220 are connected in an angle shape. The horizontally arranged plate 4 240 connects the plates 220 on both sides, and the lower surface of the plate 1 210 is provided with plates 5 251 and 6 252, and the plates 5 251 and 6 252 are in contact with each other, but the upper and lower positions of the plates 5 251 and 6 252 are not limited.

[0059] Fig.11 The figure shows the matching relationship between the fifth plate 251 and the sixth plate 252. The fifth plate 251 is provided with a fourth through hole 251b corresponding to the first through hole 211, and the sixth plate 252 is provided with a fifth through hole 252b corresponding to the first through hole 211. The functions of the fourth through hole 251b and the fifth through hole 252b are the same as those of the third through hole 231.

[0060] In addition, the through hole four 251b of the plate five 251 will be provided with a section of beveled surface two 251c, and the through hole five 252b of the plate six 252 will be provided with a section of beveled surface three 252c. When the plates five 251 and six 252 are kept in relative motion for shearing, the beveled surface two 251c is in the same movement direction C1 as the plate five 251, the beveled surface three 252c is in the same movement direction C2 as the plate six 252, and the surface where the cutting edge formed by the beveled surface two 251c is located is in contact with the surface where the cutting edge formed by the beveled surface three 252c is located, thereby achieving a better shearing effect.

[0061] In addition, a pressure rod 260 is provided in the middle of each group of slopes 110, and convex wings 261 are provided on both sides of the pressure rod 260. The convex wings 261 have inclined contact surfaces 262, and the contact surfaces 262 of the convex wings 261 on both sides are inclined in opposite directions. The fifth plate 251 and the sixth plate 252 are respectively in contact with the contact surfaces 262 of the convex wings 261 on both sides. Fig.10 As shown in the figure, the edge of plate five 251 directly abuts against the contact surface 262 at the proximal end, while plate six 252 has an extension arm 252a abutting against the contact surface 262 at the distal end. When the pressure rod 260 moves downward, the contact surfaces 262 on both sides squeeze plate five 251 and plate six 252 respectively, so that plate five 251 is pressed into plate one 210, while plate six 252 is pulled out of plate one 210, and then plate five 251 and plate six 252 directly form shear through relative movement, so as to cut off and separate the roots more quickly; and through one operation of the pressure rod 260, the roots on the slopes 110 on both sides can be cut off and separated at the same time, further improving the efficiency of the separation operation.

[0062] It should be noted that the above combination Fig.10 The description is only to provide a preferred embodiment and is not intended to be limiting. In actual application, it is permitted to set a single-sided slope 110 according to needs, and it is also permitted to set only plate five 251 or plate six 252.

[0063] In order to maintain the stability of the pressure rod 260, a base 263 is set on the plate 240, so that the lower end of the pressure rod 260 is slidably set in the base 263, which can maintain the stability of the pressure rod 260 in the vertical direction. At the same time, a spring (not shown in the figure) can be set in the base 263 to resist the pressure rod 260. On the one hand, when not in operation, the pressure rod 260 is lifted up by the spring to maintain the upper state of the pressure rod 260. On the other hand, after the pressure rod 260 is pressed down to the lower state, the spring can play a role in resetting the pressure rod 260.

[0064] On the other hand, the edge of the fifth plate 251 is provided with a rotating cylinder in contact with the contact surface 262, so as to realize rolling friction instead of sliding friction and reduce the operation resistance; the extension arm 252a of the sixth plate 252 is also provided with a rotating cylinder in contact with the contact surface 262, so as to realize rolling friction instead of sliding friction and reduce the operation resistance. At the same time, in order to avoid the extension arms 252a on both sides from interfering with each other, the extension arms 252a on both sides can be staggered.

[0065] A tension spring may be added between the edge of the fifth plate 251 and the extension arm 252a of the sixth plate 252. The tension spring can not only replace the function of the spring piece 232 originally provided on the third plate 230, but also can stably reset the fifth plate 251 and the sixth plate 252. More specifically, when there is no need to shear and separate the roots, the pressure rod 260 is in an upper state and the tension spring is in a natural unstretched state. In this state, the extension arm 252a of the plate six 252 will naturally fit on the contact surface 262, and the plate five 251 will slide down due to gravity because it does not have the spring sheet 232. The tension spring can limit the downward movement of the plate five 251 by connecting with the edge of the plate five 251, so that the edge of the plate five 251 also naturally fits on the contact surface 262; when shearing and separating the roots, the pressure rod 260 changes from an upper state to a lower state. Combined with the above, the tension spring will be stretched to store elastic potential energy. Once the pressure on the pressure rod 260 is released, the pressure rod 260 itself will be lifted up by the spring in the base 263. At the same time, the tension spring will also contract to pull the plate five 251 and the plate six 252 closer, so that the plate five 251 and the plate six 252 return to their initial state.

[0066] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
