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 halophytes is an important means, and the survival rate of seedling cultivation directly determines the subsequent planting effect. However, the halophyte seedling cultivation process faces many technical problems, and the traditional cultivation method cannot meet the needs of efficient and high-quality cultivation.

[0003] In terms of culture solution supply, traditional cultivation mostly relies on artificial timed irrigation, which not only consumes a lot of manpower, but also is difficult to accurately control the irrigation amount and frequency. If the irrigation is insufficient, the seedlings are prone to grow slowly due to water and nutrient deficiency. If the irrigation is too much, it may lead to root rot due to lack of oxygen. Artificial operation cannot guarantee that each seedling receives uniform nutrient supply, and uneven growth may occur, affecting the overall cultivation quality. At the same time, salt concentration adjustment is a key link in halophyte seedling cultivation. Halophyte seedlings need to gradually adapt to a high-salt environment from a low-salt environment. If the salt concentration suddenly increases, the seedlings are prone to dehydration and death. If the concentration increases too slowly or insufficiently, the seedlings cannot adapt to the subsequent growth environment of saline-alkali land, greatly reducing the survival rate of transplanting. At the same time, in the traditional cultivation container, the salt in the culture solution is prone to sedimentation, causing uneven concentration in the upper and lower layers, and the seedlings absorb different amounts of salt, further affecting the growth stability. At the same time, in the transplanting process, the traditional seedling cultivation container is difficult to completely separate the seedlings from the soil due to design defects. When the seedlings are taken out manually, the roots and stems are easily pulled, causing root and stem breakage, which seriously affects the survival rate of the seedlings after transplanting.

[0004] These problems jointly restrict the cultivation efficiency and survival rate of halophyte seedlings, and cannot meet the demand for high-quality seedlings in 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 that can accurately control the supply of culture solution, gradually adjust the salt concentration, and facilitate transplanting.

DETAILED DESCRIPTION

[0019] 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.

[0020] As Figures 1-13 shown, a halophyte seedling cultivation box for saline-alkali soil provided by one embodiment of the present application comprises a box 101, an electric telescopic rod 102 is fixedly installed on the side wall of the box 101, 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, a seedling tray 107 is fixedly installed at the bottom end of the connecting rod 106, seedling boxes 108 in a rectangular array are fixedly installed in the seedling tray 107, water permeable holes 111 are formed at the bottom of the seedling boxes 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. The box 101 further comprises a seedling lifting mechanism arranged below the seedling tray 107, which is used to lift seedlings out of the seedling boxes 108 after seedling; a locking mechanism arranged in the support block 105, which is used to lock the support block 105 in the bracket 104; and a disturbance mechanism arranged in the box 101, which is used to disturb the culture solution in the box 101.

[0021] 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.

[0023] As an embodiment of the present application, 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 can be 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 lower retaining ring 210, 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.
