[0007] The cultivation assembly includes a partition, a piston plate and a fixed plate arranged in sequence along the vertical direction, the partition is fixedly connected to the inside of the seedling box, a plurality of groups of growth grooves are opened on the upper surface of the partition, a sleeve is fixedly connected to the inner wall of the growth groove, the partition and the fixed plate are fixedly connected to the inner cavity of the seedling box at intervals, and a hydraulic cylinder 1 is installed on the lower end surface of the fixed plate, and the hydraulic cylinder 1 is used to drive the piston plate to move;

[0008] A loading assembly is arranged inside the alignment frame, and the loading assembly includes a mounting frame and a lifting plate. A hydraulic cylinder 2 is installed on the upper end surface of the mounting frame, and the hydraulic cylinder 2 is used to drive the lifting plate to move. A plurality of guide tubes are arranged on the lower end surface of the lifting plate.

[0009] The plurality of groups of through holes, the plurality of groups of growth grooves and the plurality of groups of guide tubes are aligned one by one along the vertical direction.

[0010] As a further preference, the partition and the fixed plate are both fixedly connected to the inner cavity of the seedling box, and a water pipe is arranged outside the seedling box, and the water pipe connects the gap between the partition in the inner cavity of the seedling box and the piston plate.

[0011] As a further preference, three groups of adjustment claws are arranged at intervals at one end of the guide tube, and a plurality of tissue culture sheets are arranged inside the guide tube.

[0012] As a further preference, the adjusting claw comprises a fixing plate and a fixing strip, a section of the fixing strip is fixedly connected with an elastic claw, the other end of the elastic claw is fixedly connected with one end of the fixing plate, and the end of the elastic claw facing away from the elastic claw is fixedly connected with a limiting strip.

[0013] As a further preference, one end of the fixing strip is fixedly connected to one end of the guide tube, the elastic claw is arc-shaped, and one end of the fixing sheet is bent and fits with the outside of the elastic claw.

[0014] As a further preference, a retaining ring is provided on the upper end surface of the cultivation sheet, and both the cultivation sheet and the retaining ring are made of degradable materials.

[0015] As a further preference, the outer diameter of the guide tube is smaller than the inner diameter of the growth groove.

[0017] As a further preference, the seedling tray can move horizontally in the inner cavity of the seedling box, and the arrangement mode and inner diameter of several groups of the through holes are the same as the arrangement mode of several groups of the growth grooves.

[0018] As a further preferred embodiment, a lily seed seedling raising method adopts the above-mentioned lily seed seedling raising device, including placing an alignment frame above a seedling raising box, placing lily seeds on cultivation sheets, and placing a plurality of groups of stacked cultivation sheets into a guide tube, adjusting the position of a lifting plate by means of a second hydraulic cylinder so that the guide tube extends into the interior of the sleeve, the limit strip moves upward under the action of resistance, so that the fixed sheet pulls the elastic claw to bend outward, and the cultivation sheets inside the guide tube fall into the interior of the sleeve, and the amount of water between the partition and the piston plate is controlled by a water pipe. After the lily cultivation is completed, the height of the piston plate is adjusted by means of a first hydraulic cylinder so that the water between the partition and the piston plate rises to above the seedling tray through the sleeve and the growth groove. At this time, the cultivated lilies and the cultivation sheet collection will float to above the seedling tray with the water, and by moving the position of the seedling tray, all the cultivated lilies are put into the seedling tray, completing the one-time collection of all lily plants.

[0019] (II) Beneficial effects

[0020] The present invention provides a lily seed seedling raising device and a lily seed seedling raising method, which have the following beneficial effects:

[0021] The present invention places lily seeds into the sleeve through a cultivation sheet. After the seedlings are grown, the water level in the gap between the partition plate and the piston plate rises and enters the growth groove and the sleeve by adjusting the height of the piston plate. The cultivated lilies are lifted to the top of the through hole by the buoyancy of the water, the position of the seedling tray is moved to make the lilies fall above the seedling tray, and the piston plate is adjusted to the initial position to complete the unified collection of lily plants.

[0022] At the same time, the cultivation sheet and the retaining ring are prepared by dissolving and blending the biodegradable material with the cultivation fertilizer. When cultivating lilies, the cultivation sheet and the retaining ring can dissolve the fertilizer under the action of water, and the holes on the outside of the cultivation sheet and the retaining ring will expand after the cultivation is completed, so that the root system of the lily will be entangled with the holes in the cultivation sheet and the retaining ring caused by the dissolution of the fertilizer during the cultivation, so that the lily cultivation seedlings will be combined with the cultivation sheet and the retaining ring when they grow up, avoiding the contact between the cultivated lily plants and the inner wall of the casing, so that the lily plants can be easily taken out without loss at one time;

[0023] In addition, when the hydraulic cylinder drives the lifting plate downward, the guide tube will enter the interior of the sleeve. As the guide tube continues to descend, the limit bar will pull the fixed plate and cause the elastic claw to bend in the opposite direction, so that the cultivation sheets inside the guide tube will fall into the sleeve. After the guide tube is driven up by the hydraulic cylinder, the elastic claw will resume its deformation and clamp and limit the second-to-last group of cultivation sheets, thereby completing the individual placement of the cultivation sheets and effectively improving the efficiency of lily cultivation.

DETAILED DESCRIPTION

[0035] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0036] like Figure 1-8 As shown, this embodiment provides a lily seed seedling raising device, including a seedling raising box 100 and a loading box alignment frame 200 arranged above the seedling raising box 100, the seedling raising box 100 has an opening at the top, the inner cavity of the seedling raising box 100 is sequentially provided with a seedling tray 101 and a cultivation component for raising seedlings in the vertical direction, and the upper end surface of the seedling tray 101 is provided with a plurality of through holes 103;

[0037] The cultivation assembly includes a partition 102, a piston plate 105 and a fixed plate 106 arranged in sequence along the vertical direction, the partition 102 is fixedly connected to the inside of the seedling box 100, a plurality of groups of growth grooves 104 are opened on the upper end surface of the partition 102, a sleeve 108 is fixedly connected to the inner wall of the growth groove 104, the partition 102 and the fixed plate 106 are fixedly connected to the inner cavity of the seedling box 100 at intervals, and a hydraulic cylinder 107 is installed on the lower end surface of the fixed plate 106, and the hydraulic cylinder 107 is used to drive the piston plate 105 to move;

[0038] A loading assembly is arranged inside the alignment frame 200, and the loading assembly includes a mounting frame 201 and a lifting plate 203. A hydraulic cylinder 202 is installed on the upper end surface of the mounting frame 201, and the hydraulic cylinder 202 is used to drive the lifting plate 203 to move. A plurality of guide tubes 204 are arranged on the lower end surface of the lifting plate 203.

[0039] The plurality of groups of through holes 103, the plurality of groups of growth grooves 104 and the plurality of groups of guide tubes 204 are aligned one by one along the vertical direction.

[0040] like Figure 1 and 2 As shown, several groups of seedling boxes 100 can be combined and spliced, a limit slider is provided at the bottom of the support leg of the alignment frame 200, and two groups of alignment slide grooves are provided above the seedling boxes 100. When several groups of seedling boxes 100 are spliced ​​together, the position of the alignment frame 200 on different seedling boxes 100 can be changed by sliding, thereby facilitating the addition of cultivation sheets to different seedling boxes 100.

[0041] Specifically, after the lily seeds are cultivated, the gap between the piston plate 105 and the partition 102 can make the lily seedlings inside the sleeve 108 float up through buoyancy, so that they are all collected inside the seedling tray 101, effectively improving the convenience of uniformly collecting the seedlings after cultivation.

[0042] Furthermore, the partition 102 and the fixing plate 106 are both fixedly connected to the inner cavity of the seedling box 100 , and a water pipe is arranged outside the seedling box 100 , and the water pipe connects the gap between the partition 102 in the inner cavity of the seedling box 100 and the piston plate 105 .

[0043] Specifically, water or nutrient solution can be added to the gap between the partition plate 102 and the piston plate 105 through the water pipe, and the total amount of solution in the gap between the partition plate 102 and the piston plate 105 can also be adjusted through the water pipe.

[0044] It is understandable that there may be more than one group of water pipes installed outside the seedling raising box 100, and when several groups of seedling raising boxes 100 are spliced ​​together, the several groups of seedling raising boxes 100 may be connected through the water pipes.

[0045] like Figure 7-10As shown, three groups of adjusting claws are arranged at intervals at one end of the guide tube 204, and a plurality of groups of culture sheets 205 are arranged inside the guide tube 204.

[0046] Furthermore, the adjustment claw includes a fixing plate 206 and a fixing strip 208 , a section of the fixing strip 208 is fixedly connected with an elastic claw 209 , the other end of the elastic claw 209 is fixedly connected with one end of the fixing plate 206 , and the end of the elastic claw 209 facing away from the elastic claw 209 is fixedly connected with a limiting strip 210 .

[0047] Furthermore, one end of the fixing strip 208 is fixedly connected to one end of the guide tube 204 , the elastic claw 209 is arc-shaped, and one end of the fixing sheet 206 is bent and fits with the outside of the elastic claw 209 .

[0048] Furthermore, the limiting bars 210 are perpendicular to the fixing plate 206 , and the external extension lengths of the three groups of limiting bars 210 are greater than the inner diameter of the growth groove 104 .

[0049] Specifically, when the hydraulic cylinder 202 drives the guide tube 204 to move to the inside of the sleeve 108, the limit bar 210 is blocked outside the through hole 103. As the guide tube 204 continues to descend, the limit bar 210 will pull the fixing plate 206 and cause the elastic claw 209 to bend in the opposite direction, so that the cultivation sheet 205 inside the guide tube 204 will fall into the inside of the sleeve 108. After the guide tube 204 is driven to rise by the hydraulic cylinder 202, the elastic claw 209 resumes its deformation and clamps and limits the penultimate group of cultivation sheets 205, thereby completing the individual placement of the cultivation sheets 205.

[0050] Furthermore, a retaining ring 207 is disposed on the upper end surface of the cultivation sheet 205 , and both the cultivation sheet 205 and the retaining ring 207 are made of degradable materials.

[0051] The cultivation sheet 205 and the retaining ring 207 may be prepared by electrostatic spinning after the degradable material and the cultivation fertilizer are dissolved and blended.

[0052] Specifically, when the cultivation sheet 205 is cultivating lilies, during the time of lily cultivation, the fertilizer in the cultivation sheet 205 and the retaining ring 207 will dissolve under the action of water, so that after the cultivation is completed, the cultivation sheet 205 and the retaining ring 207 will be degraded, causing the external holes to expand, so that when the lilies are cultivated, the roots will be entangled with the holes in the cultivation sheet 205 and the retaining ring 207 caused by the dissolution of the fertilizer, so that the lily seedlings will be combined with the cultivation sheet 205 and the retaining ring 207 when they grow up.

[0053] Furthermore, the cultivation sheet 205 and the retaining ring 207 can effectively prevent the cultivated lily plants from contacting and getting entangled with the inner wall and the bottom of the sleeve 108, thereby making it easy to remove the lily plants without damage at one time.

[0054] The fertilizers in the cultivation sheet 205 and the retaining ring 207 are sufficient for lily cultivation, and the material degradation degree of the cultivation sheet 205 and the retaining ring 207 does not exceed 30% of the total material during the lily cultivation cycle.

[0055] At the same time, the lily seedlings are grown by using the fertilizers in the cultivation sheet 205 and the retaining ring 207, which can effectively reduce the number of times that personnel add fertilizers, thereby improving the convenience of cultivation.

[0056] Furthermore, the outer diameter of the guide tube 204 is smaller than the inner diameter of the growth groove 104 .

[0057] Furthermore, the seedling tray 101 can move horizontally in the inner cavity of the seedling box 100, and the arrangement mode and inner diameter of the plurality of groups of through holes 103 are the same as the arrangement mode of the plurality of groups of growth grooves 104.

[0058] The present embodiment also provides a lily seed seedling raising method, which uses the above-mentioned lily seed seedling raising device, including placing an alignment frame 200 above the seedling raising box 100, placing lily seeds on the cultivation sheets 205, and placing a plurality of stacked cultivation sheets 205 into the guide tube 204, adjusting the position of the lifting plate 203 by the hydraulic cylinder 202, so that the guide tube 204 extends into the sleeve 108, and the limit bar 210 moves upward under the action of resistance, so that the fixing sheet 206 pulls the elastic claw 209 to bend outward, and the cultivation sheet 205 in the guide tube 204 will fall. To the inside of the sleeve 108, the water volume between the partition 102 and the piston plate 105 is controlled by the water pipe. After the lily cultivation is completed, the height of the piston plate 105 is adjusted by the hydraulic cylinder 107, so that the water between the partition 102 and the piston plate 105 rises to the top of the seedling tray 101 through the sleeve 108 and the growth groove 104. At this time, the cultivated lilies and the cultivation sheet 205 collection will float to the top of the seedling tray 101 with the water. By moving the position of the seedling tray 101, all the cultivated lilies can be put into the seedling tray 101, completing the one-time collection of all lily plants.

[0059] The lily seed seedling raising device provided by the present invention is as follows: by placing lily seeds into the sleeve 108 through the cultivation sheet 205, after the seedling raising is completed, by adjusting the height of the piston plate 105, the water level in the gap between the partition plate 102 and the piston plate 105 rises and enters the growth groove 104 and the sleeve 108, the cultivated lilies are lifted to the top of the through hole 103 by the buoyancy of the water, the position of the seedling tray 101 is moved, the lilies fall to the top of the seedling tray 101, and then the piston plate 105 is adjusted to the initial position to complete the unified collection of lily plants;

[0060] At the same time, the cultivation sheet 205 and the retaining ring 207 are prepared by dissolving and blending the biodegradable material with the cultivation fertilizer. When cultivating lilies, the cultivation sheet 205 and the retaining ring 207 can dissolve the fertilizer under the action of water, and the holes on the outside of the cultivation sheet 205 and the retaining ring 207 will expand after the cultivation is completed, so that the root system of the lily will be entangled with the holes of the cultivation sheet 205 and the retaining ring 207 caused by the dissolution of the fertilizer during the cultivation, so that the lily cultivation seedlings will be combined with the cultivation sheet 205 and the retaining ring 207 when they grow up, avoiding the contact between the cultivated lily plants and the inner wall of the sleeve 108, so that the lily plants can be easily taken out without loss at one time;

[0061] In addition, while the hydraulic cylinder 202 drives the lifting plate 203 to move downward, the guide tube 204 will enter the interior of the sleeve 108. As the guide tube 204 continues to descend, the limit bar 210 will pull the fixing plate 206 and cause the elastic claw 209 to bend in the opposite direction, so that the cultivation sheet 205 inside the guide tube 204 will fall into the interior of the sleeve 108. After the guide tube 204 is driven to rise by the hydraulic cylinder 202, the elastic claw 209 resumes its deformation and clamps and limits the penultimate group of cultivation sheets 205, thereby completing the individual placement of the cultivation sheets 205 and effectively improving the efficiency of lily cultivation.

[0062] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
