The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0045] Example 1

[0046] like Figure 1-4 As shown, the present invention provides a technical solution: a highly efficient cultivation device for ophiopogon japonicus in landscaping, comprising a seedling placement structure 1 for placing ophiopogon japonicus seedlings to be cultivated at intervals and a cultivation frame 2 for taking and supporting the seedling placement structure 1;

[0047] The seedling placement structure 1 includes a plurality of placement buckets 12 slidably connected to the sliding frame 11. The placement buckets 12 are used to place the Ophiopogon japonicus seedlings and are made of stainless steel. The placement buckets 12 are inclined to have openings at the upper end and both ends. The opening size at the lower point of the inclination is smaller than the opening size at the higher point. The design of being wide at the top and narrow at the bottom can better guide the Ophiopogon japonicus seedlings to slide.

[0048] The cultivation frame 2 is composed of a bottom plate 21, a two-stage bracket 22, and a handle bracket 23, and is fixed in the middle from bottom to top in sequence, and the composition method includes welding or bolting. A planting groove 24 with a length greater than the sliding frame 11 is opened along the length direction on the upper end surface of the bottom plate 21, and is connected to the lower opening of the placing bucket 12 for the Ophiopogon japonicus seedlings to slide through;

[0049] The low point opening of the placing bucket 12 is fitted with the limiting plate 3, and the limiting plate 3 is "L"-shaped to reduce the size and weight, and at the same time provides a barrier and mounting surface for fitting the opening end and the end of the spring telescopic component 4, and the limiting plate 3 is opposite to the planting groove 24, and the spring telescopic component 4 and the traction handle 5 are installed between the two-stage bracket 22 and the handle bracket 23 on both sides and the center of the top end respectively. The gripping end of the handle bracket 23 is held and the traction handle 5 is pinched and pulled to shrink the spring telescopic component 4, and then the limiting plate 3 is translated upward to open the low point opening of the placing bucket 12, and the traction handle 5 is released to reset the spring telescopic component 4;

[0050] The number of spring expansion and contraction components 4 on each side increases according to the length of the limiting plate 3 of the planting groove 24, but is generally not more than two.

[0051] A slotting knife 6 is provided at the bottom of the bottom plate 21, close to the planting groove 24 and away from the seedling placement structure 1. The slotting knife 6 can be fixed with bolts or welded to the bottom of the bottom plate 21. The two end surfaces form a knife head at the end to slot the soil.

[0052] like Figure 2 and 3 As shown, in order to move and fix the placement bucket 12, a movable support plate 121 is provided at the bottom of the placement bucket 12. The placement bucket 12 is tilted and supported by the movable support plate 121 and slides in the sliding frame 11. A plurality of fixing holes 111 are opened in the sliding frame 11 at equal intervals along the length, and mounting holes 122 are opened through the movable support plate 121 and corresponding to the fixing holes 111. The mounting holes 122 are fixed relative to the fixing holes 111 by bolts.

[0053] Generally, after adjustment, cultivation is carried out on large areas of the ground (small areas will not use this device), so there is no need for subsequent adjustments after one adjustment.

[0054] like Figure 1 As shown, a pedal 211 is provided on the side of the bottom plate 21 close to the seedling placement structure 1, and the pedal 211 is welded to the bottom plate 21. The second-section bracket 22 and the planting trough 24 are in a rectangular structure to ensure structural stability. The length of the arms on both sides of the handle bracket 23 is 20-80cm, and 20-80cm is selected according to the needs and the height of the planting personnel to meet the use. The gripping rod is connected away from the end of the second-section bracket 22, and the entire device is picked up by the gripping rod. If necessary, a gripping rod can be added on the outside of the second-section bracket 22 to assist in picking up.

[0055] Specifically, the two-section bracket 22 is provided with a through slot 221 between the two side arms for the traction handle 5 to pass through.

[0056] like Figure 2 As shown, the spring telescopic assembly 4 includes a telescopic sleeve 41 and a spring member 42. The spring member 42 is sleeved on the periphery of the telescopic sleeve 41. Both ends of the telescopic sleeve 41 and the spring member 42 are fixed between the limit plate 3 and the second-stage bracket 22. The telescopic sleeve 41 is composed of a sleeve and a slide rod. The slide rod slides in the sleeve to guide the extension and contraction of the spring member 42.

[0057] The sleeve serves as a track for the slide bar to slide. The sleeve provides a stable and smooth sliding surface, ensuring that the slide bar can move smoothly within it.

[0058] The slide bar is designed to slide freely inside the sleeve, and its movement plays a key guiding role in the extension and retraction of the spring member 42. When an external force (pulling the handle 5, resetting the spring member 42) acts on the slide bar, the slide bar will slide inside the sleeve.

[0059] like Figure 4 As shown, the slotting knife 6 is welded with an arc support plate 61 downwardly on the side of the planting groove 24. The arc support plate 61 is designed so as not to damage the seedlings when supporting the soil.

[0060] A method for cultivating ophiopogon japonicus using the above-mentioned efficient cultivation device, such as Figure 5 As shown, the following steps are included:

[0061] S1, land preparation, seedling treatment, planting spacing selection, and adjustment of the seedling placement structure 1 according to the planting spacing;

[0062] S2, placing the processed Ophiopogon japonicus seedlings in the placing bucket 12, with the roots of the Ophiopogon japonicus seedlings facing the limiting plate 3, and holding the handle bracket 23 to move to the soil to be planted;

[0063] S3, placing the slotting knife 6 on the planting soil, tilting it along the planting direction, with the tilted end facing the planting personnel, so that the slotting knife 6 is in a tilted state, stepping on the pedal 211 to make the slotting knife 6 penetrate into the soil, and then adjusting the tilting angle of the slotting knife 6 in the reverse direction to expand the soil groove pressed by the slotting knife 6;

[0064] The inclination angle of the slotting knife 6 is adjusted in the reverse direction to be the slotting angle.

[0065] S4, pull back the slotting knife 6, make the cultivation frame 2 vertical state, hold the handle bracket 23 and pinch and pull the traction handle 5 to shrink the spring expansion assembly 4, then the limit plate 3 translates upward, the lower opening of the placing bucket 12 opens, and the Ophiopogon japonicus seedlings placed in the placing bucket 12 slide through and enter the soil groove pressed by the slotting knife 6 through the planting groove 24;

[0066] S5, pull up the slotting knife 6 and place it on the other side of the expanded soil in S3, with the inclined end facing the planting personnel, so that the slotting knife 6 is in an inclined state. At this time, the arc support plate 61 contacts the expanded soil, and at the same time, the slotting knife 6 is gently dragged back, and the soil is restored to the soil groove pressed by the slotting knife 6, and the cultivation is completed.

[0067] It should be emphasized that step S5 is repeated when the soil does not completely cover the roots of the Ophiopogon japonicus seedlings.

[0068] In the above method, S1 land preparation includes deep plowing and fertilizing of the soil to be planted, which is conducive to the slotting of the slotting knife 6 and is also a necessary process for conventional planting;

[0069] The seedlings are processed by the division propagation method, in which the tuberous roots and surrounding fibrous roots of the seedlings are cut off to make them independent plants, and the tuberous root base is cut to the position where the white part appears at the root, and then the placement bucket 12 is adapted to place the seedlings, which is also a necessary process for conventional planting.

[0070] It should also be noted that the adjustment of the seedling placement structure 1 is based on the selection of the cultivation spacing. According to the selection of the cultivation spacing of 4-10 cm (the conventional planting spacing selection or standard, deviations are allowed), the movable pallet 121 slides on the sliding frame 11, and each movable pallet 121 is fixed to the fixing hole 111 by bolts through the mounting hole 122 to complete the spacing adjustment. The number and spacing of the fixing holes 111 are designed according to needs.

[0071] 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.
