Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of seedling raising, and particularly relates to a halophyte seedling cultivation box for saline-alkali land. BACKGROUND

[0002] In ecological restoration and improvement of saline-alkali land, planting of halophyte is an important means, and survival rate of seedling cultivation directly determines subsequent planting effect. However, halophyte seedling cultivation process faces many technical problems, and traditional cultivation method cannot meet the demand of efficient and high-quality cultivation.

[0003] In the aspect of culture solution supply, traditional cultivation mostly relies on artificial timed irrigation, which not only consumes a large amount of manpower, but also is difficult to accurately control irrigation amount and frequency. If irrigation is insufficient, seedlings are prone to grow slowly due to water and nutrient deficiency. If irrigation is excessive, root rot may be caused due to lack of oxygen, and artificial operation cannot guarantee that each seedling obtains uniform nutrient supply, which is prone to cause uneven growth, affecting overall cultivation quality. Meanwhile, salt concentration adjustment is a key link of halophyte seedling cultivation. Halophyte seedlings need to gradually adapt to high-salt environment from low-salt environment. If salt concentration suddenly increases, seedlings are prone to die of dehydration. If concentration increases too slowly or insufficiently, seedlings cannot adapt to subsequent growth environment of saline-alkali land, greatly reducing transplanting survival rate. Meanwhile, in traditional cultivation containers, salt in culture solution is prone to deposit, causing uneven concentration in upper and lower layers, and seedlings absorb inconsistent salt, further affecting growth stability. Meanwhile, in the process of transplanting, traditional seedling cultivation containers are difficult to realize complete separation of seedlings and soil due to structural design defects. When seedlings are taken manually, seedling roots are prone to be pulled, causing root breakage, and seriously affecting survival rate of seedlings after transplanting.

[0004] These problems jointly restrict cultivation efficiency and survival rate of halophyte seedlings, and cannot meet the demand of high-quality seedlings for large-scale ecological restoration of saline-alkali land. Therefore, it is an urgent need in the field of ecological restoration of saline-alkali land to develop a halophyte seedling cultivation device capable of accurately controlling culture solution supply, realizing gradual salt adjustment, and facilitating transplanting.

DETAILED DESCRIPTION

[0036] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below in combination with the drawings and examples.

[0037] As Figures 1-13 shown, an embodiment of the present application provides a halophyte seedling cultivation box for saline-alkali soil, which comprises a box 101, an electric telescopic rod 102 is fixedly installed on the side wall of the box 101, and a lifting frame 103 is fixedly installed at the telescopic end of the electric telescopic rod 102, a bracket 104 is formed on the upper surface of the lifting frame 103, a support block 105 is clamped in the bracket 104, a connecting rod 106 is fixedly installed at the bottom of the support block 105, and a seedling tray 107 is fixedly installed at the bottom end of the connecting rod 106, a seedling box 108 in a rectangular array is fixedly installed in the seedling tray 107, and a water permeable hole 111 is formed at the bottom of the seedling box 108, a salinity sensor 109 and a liquid level sensor 110 are fixedly installed on the inner walls of the two sides of the box 101, and a drain pipe 112 is communicatively installed on the outer wall of one side of the box 101, further comprising: a seedling lifting mechanism, which is arranged below the seedling tray 107 and is used for lifting seedlings out of the seedling box 108 after seedling; a locking mechanism, which is arranged in the support block 105 and is used for locking the support block 105 in the bracket 104; and a disturbance mechanism, which is arranged in the box 101 and is used for disturbing the culture solution in the box 101.

[0038] In the process of cultivating halophyte seedlings, the soil and the seeds of the halophyte to be cultivated are placed in the seedling box 108 of the seedling tray 107 in sequence, and then the culture solution with a low salt concentration is poured into the box 101. Then, the lifting frame 103 is driven to move downward by the electric telescopic rod 102. Since the supporting block 105 is fixed in the supporting groove 104 on the surface of the lifting frame 103 by the locking mechanism, the connecting rod 106 below the supporting block 105 moves downward together, and then drives the seedling tray 107 to move downward synchronously, so that the lower half of the seedling box 108 is immersed in the culture solution in the box 101. After maintaining this state for three to five minutes, the culture solution seeps into the seedling box 108 through the water-permeable hole 111 at the bottom of the seedling box 108. Then, the lifting frame 103 is driven to move upward by the electric telescopic rod 102, so that the seedling box 108 is separated from the culture solution. This operation needs to be repeated every 24 hours to ensure that the plant seedlings can timely obtain the culture solution. When the seedlings grow to a certain stage, the remaining amount of the culture solution can be detected by the liquid level sensor 110, and the salt concentration of the remaining culture solution can be monitored by the salinity sensor 109. According to the two data, the culture solution with a higher salt concentration is prepared and poured into the box 101, so that the overall salt concentration is higher than before. With the continuous growth of the seedlings, the salt concentration of the culture solution needs to be gradually increased until it is close to the salt concentration of the saline-alkali land to be transplanted. This gradual salt concentration adjustment method can significantly improve the survival rate of halophyte seedlings. In addition, before the seedling box 108 is immersed in the culture solution, the disturbance mechanism can be started to stir the culture solution in the box to avoid the deposition of salt substances, which causes the concentration difference between the upper and lower layers. When the seedling cultivation is completed and the seedlings need to be transplanted, since the plant roots and the soil are combined in the seedling box 108 for a long time, the roots are easily broken when directly taken out. At this time, the seedlings and the soil can be completely taken out from the seedling box 108 by the seedling top mechanism, so as to effectively reduce the damage to the roots in the transplanting process. After all the seedlings are transplanted, the supporting block 105 can be fixed by the locking mechanism, and the seedling tray 107 can be taken out from the box 101 for cleaning, which is convenient to operate and has better use effect.

[0039] As an embodiment of the present application, please refer to Figure 5 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10The seedling-supporting mechanism includes a movable plate 201 located below the seedling tray 107. The outer wall of the movable plate 201 has mounting openings 204 arranged in a rectangular array and corresponding to the seedling box 108. A movable rod 202 is fixedly mounted on the upper surface of the movable plate 201, penetrating the seedling tray 107. A gripping rod 203 is fixedly mounted at the top of the movable rod 202. A seedling-supporting plate 205 is movably disposed within the seedling box 108, and a supporting rod 206 is fixedly mounted at the bottom of the seedling-supporting plate 205. The supporting rod 206 penetrates the seedling box 108, and a supporting rod is fixedly mounted at its bottom end. Mounting block 207 has a rotating plate 208 rotatably mounted on its outer side, and the rotating plate 208 is located in the mounting opening 204. A horizontal plate 209 is fixedly mounted on the inner wall of one side of the mounting opening 204, and the outer wall of the rotating plate 208 is in contact with the outer wall of the horizontal plate 209. A lower retaining ring 210 is fixedly mounted on the outer wall of the movable rod 202, and the lower retaining ring 210 is located below the seedling tray 107. An upper retaining ring 211 is fixedly mounted on the outer wall of the movable rod 202, and the upper retaining ring 211 is located above the seedling tray 107. A connecting component is also provided below the seedling tray 107 for connecting the rotating plate 208. The plate 208 and the horizontal plate 209, and the outer side of the handle 203 are also provided with a limiting component to limit the position of the handle 203. When it is necessary to push out the seedlings and soil in the seedling box 108, the handle 203 can be pulled upward. The handle 203 drives the movable rod 202 to move upward. Since the movable rod 202 is fixedly connected to the movable plate 201, the movable plate 201 moves upward synchronously with the movable rod 202. The mounting openings 204 on the upper surface of the movable plate 201 correspond one-to-one with the seedling box 108. The rotating plate 208 in the mounting opening 204 is initially in contact with the outer wall of the horizontal plate 209. Furthermore, it is connected to the horizontal plate 209 through the connecting component. During the upward movement of the movable plate 201, the rotating plate 208 will be supported by the horizontal plate 209, causing the rotating plate 208 to move upward along with the movable plate 201. The top rod 206 also moves upward accordingly. The seedling plate 205 at the top of the top rod 206 moves upward synchronously inside the seedling box 108, eventually pushing out the plant seedlings and soil inside the seedling box 108 as a whole. At this time, the height of the holding rod 203 can be limited by the limiting component, so that the plant seedlings and soil inside the seedling box 108 are always kept in the state of being pushed out, making it convenient to pick them up.

[0040] As one embodiment of the present invention, please refer to Figure 8 , Figure 9 and Figure 10The connecting assembly comprises a mounting cylinder 301 fixedly installed in the seedling tray 107, a plug rod 303 movably installed in the mounting cylinder 301, a handle 302 fixedly installed at the top end of the plug rod 303, and the bottom end of the plug rod 303 penetrating through the rotating plate 208 and the horizontal plate 209. The plug rod 303 is inserted into the rotating plate 208 and the horizontal plate 209, thereby connecting the rotating plate 208 and the horizontal plate 209. When the horizontal plate 209 is lifted, the rotating plate 208 is also lifted. However, when the plant seedlings in some of the seedling boxes 108 grow slowly and still need to be cultivated for a period of time before transplanting, the plug rod 303 corresponding to the side of the seedling box 108 is directly pulled out of the mounting cylinder 301, thereby disconnecting the rotating plate 208 and the horizontal plate 209. When the movable plate 201 is lifted, the rotating plate 208 is rotated under the pushing action of the horizontal plate 209, so that the top rod 206 above the rotating plate 208 is not lifted, and the plant seedlings are not lifted, thereby enabling the slowly growing plant seedlings to remain in the seedling box 108 for further cultivation, and greatly improving the degree of freedom. Further, the lifting amount of the movable plate 201 is limited under the limiting action of the upper retaining ring 211, so that the rotating plate 208 is always located above the horizontal plate 209, thereby avoiding falling. The lowering amount of the movable plate 201 is limited under the limiting action of the upper retaining ring 211, so that the rotating plate 208 is just parallel to the horizontal plate 209, thereby facilitating subsequent insertion of the plug rod 303 into the rotating plate 208 and the horizontal plate 209.

[0041] As an embodiment of the present application, please refer to Figure 5 The limiting assembly comprises a sleeve 401 rotatably sleeved outside the handle 203, a clamping rod 402 fixedly installed on the outer wall of the sleeve 401, a vertical plate 403 fixedly installed on the upper surface of the seedling tray 107, and a clamping groove 404 formed at the top end of the vertical plate 403 and matched with the clamping rod 402. When it is necessary to limit the height of the handle 203, the sleeve 401 outside the handle 203 is directly rotated, so that the clamping rod 402 outside the sleeve 401 is clamped in the clamping groove 404 at the top end of the vertical plate 403, thereby quickly limiting the position of the handle 203.

[0042] As an embodiment of the present application, please refer to Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7The locking mechanism comprises a telescopic groove 501 formed in the outer wall of one side of the supporting block 105, a through hole 502 formed in the upper surface of the supporting block 105 and communicated with the telescopic groove 501, a locking plate 503 movably installed in the telescopic groove 501, a handle 504 fixedly installed on the upper surface of the locking plate 503 and penetrating through the through hole 502, a locking frame 505 fixedly installed on the upper surface of the lifting frame 103, and the locking plate 503 is inserted into the locking frame 505. When the position of the supporting block 105 needs to be locked, the handle 504 is held to drive the locking plate 503 to move in the supporting block 105 until the locking plate 503 is inserted into the locking frame 505, so that the position of the supporting block 105 can be quickly locked. When the locking is to be released, the handle 504 is moved reversely to make the locking plate 503 move out of the locking frame 505, and the handle 504 can also be directly lifted upward, so that the seedling tray 107 can be directly taken out of the box body 101 for cleaning operation.

[0043] As an embodiment of the present application, please refer to Figure 2 、 Figure 12 and Figure 13 The disturbance mechanism comprises a liquid pump 601 fixedly installed at the bottom of the box body 101, a suction pipe 602 communicatedly installed at the suction end of the liquid pump 601, an end of the suction pipe 602 communicated with the bottom of the box body 101, a liquid guide pipe 603 communicatedly installed at the liquid guide end of the liquid pump 601, a spray head 604 communicatedly arranged at an end of the liquid guide pipe 603, and the spray head 604 is located in the box body 101. The culture solution in the box body 101 can be sucked out through the suction pipe 602 on the liquid pump 601, then introduced into the spray head 604 through the liquid guide pipe 603 and sprayed out, so that the culture solution in the box body 101 can be disturbed, avoiding the deposition of salt substances to cause the uneven concentration of upper and lower layers.

[0044] As an embodiment of the present application, please refer to Figure 11 、 Figure 12 and Figure 13 The upper surface of the lifting frame 103 is provided with a cover groove, and the cover groove is provided with a box cover 701. The specific material of the box cover 701 is not limited, and in the embodiment, the box cover 701 is preferably made of transparent plastic material. The lower surface of the lifting frame 103 is fixedly installed with a fence 702, and the top end of the box body 101 is provided with a ring groove, and the fence 702 is movably installed in the ring groove. The box cover 701 and the fence 702 can prevent the culture solution from evaporating rapidly, play a certain moisturizing effect, and further improve the survival rate of plant seedlings.
