[0038] Nutrient component 3 includes an annular water collection seat 31, a pH adjustment box 32, and a nutrient box 33, which are respectively disposed on the surface of the upper cylinder 11 and connected to the interior of the upper cylinder 11.

[0039] It should be noted that a rubber pad (not shown in the figure) is provided between the bottom of the feeding tray 22 and the top of the drainage tray 24 described in this embodiment. The rubber pad is bonded and fixed to the bottom of the feeding tray 22, and the drainage tray 24 is slidably connected to the surface of the rubber pad. Drainage holes 221 are provided at corresponding positions on the surfaces of the feeding tray 22, the rubber pad and the drainage tray 24.

[0040] It should be noted that the top of the threaded screw 23 described in this embodiment has a blunt end structure to avoid damage to the root system. To further prevent damage to the root system, the holes on the orifice plate 13 need to be evenly spaced in a ring and far away from the center area of ​​the orifice plate 13.

[0041] It should be noted that, in this embodiment, one end of the threaded screw 23 extends through the bottom of the fixing plate 14 and is fixedly connected to the drive handle 231.

[0042] It should be understood that this utility model achieves precise control of the growth environment of Paeonia lactiflora through the synergistic effect of the container body 1, the adjustment component 2, the nutrient component 3, and the adjustment support 4. The specific principle is as follows:

[0043] Container body 1 and space adjustment principle: Container body 1 consists of an upper cylinder 11 and a lower cylinder 12, which are connected by a threaded cylinder 21 in the middle. Rotating the upper cylinder 11 can change its relative height with the lower cylinder 12, thus initially adjusting the internal cultivation space.

[0044] The feeding disc 22 inside the lower cylinder 12 is threadedly connected to the threaded screw 23. Rotating the threaded screw 23 can drive the feeding disc 22 to slide vertically along the threaded cylinder 21 and the inner wall of the lower cylinder 12, further expanding the cultivation space above. In conjunction with the material troughs 26 on the surface of the upper cylinder 11 and the lower cylinder 12, soil can be filled into the newly added space to meet the root expansion needs of peony root at different growth stages.

[0045] Drainage adjustment principle: The bottom of the feeding tray 22 is provided with a drainage hole 221. The drainage tray 24 below it is fixedly connected to the adjustment handle 25. Rotating the adjustment handle 25 can drive the drainage tray 24 to rotate, so that the drainage hole 221 of the drainage tray 24 is misaligned with the drainage hole 221 of the feeding tray 22. The drainage efficiency is controlled by adjusting the overlapping area of ​​the holes, thereby precisely regulating the soil moisture.

[0046] Nutrition and environmental regulation principle: The annular water collection seat 31 in the nutrient component 3 can collect rainwater or irrigation water, and send the water into the soil in the upper cylinder 11 through the conduit with the regulating valve to realize the recycling of water resources; the pH adjustment box 32 and the nutrient box 33 respectively inject pH regulator and nutrient solution into the soil through the conduit. The detachable drip head (different orifice diameter) and the telescopic structure at the end of the conduit can adjust the injection volume and depth according to the growth needs.

[0047] Terrain Adaptation Principle: The adjustment bracket 4 achieves adjustment through a multi-stage threaded connection of bolts 42, connecting screws 44, and ground-inserting screws 45. Rotating the ground-inserting screws 45 can change the depth of insertion into the soil. Adjusting the position of the connecting screws 44 in the connecting holes 43 of the plate 41 can finely adjust the height. Adjusting the height between the plate 41 and the connecting screws 15 through bolts 42 can further calibrate the level, ultimately adapting to complex slope terrain under the forest.

[0048] The principle of ventilation and insect prevention: The L-shaped air channel in the threaded plug seat 27 connects the inner and outer air holes 271, allowing ventilation inside and outside the container without disassembly, ensuring root respiration; the annular concave part 100 on the surface of the upper cylinder 11 is equipped with an insect-proof ring 200 (which repels insects with chemical insect repellents), forming an insect-proof barrier.

[0049] It is worth mentioning that unscrewing the threaded plug seat 27 not only facilitates ventilation and soil filling, but also makes it easy to insert your hand into the lower cylinder 12 to operate the adjustment handle 25 during subsequent use. It is highly practical and effective.

[0050] According to the adjustable cultivation container for understory planting of Paeonia lactiflora provided in this embodiment of the present invention, the adjustable support 4 includes a plate 41, bolts 42, connecting holes 43, connecting screws 44, and a ground-inserting screw cylinder 45, wherein...

[0051] The plate 41 is located on one side of the bottom of the lower cylinder 12 and is threaded to the inner wall of the lower end of the connecting screw cylinder 15 by bolts 42. The connecting holes 43 are evenly opened on the surface of the plate 41. The upper end of the connecting screw 44 is threaded to the inner wall of the connecting hole 43, and the ground-inserting screw cylinder 45 is threaded to the outer surface of the lower end of the connecting screw 44.

[0052] It should be understood that, further explanation of the structure and connection relationship of the adjusting bracket 4 is needed. In complex terrain, the adjusting bracket 4 and the connecting screw 15 can cooperate to achieve three height adjustments. The first adjustment is to adjust the position of the grounding screw 45 on the outer surface of the lower end of the connecting screw 44, thereby adjusting the insertion depth to adapt to complex terrain. By adjusting the insertion depth, the plate 41 is ensured to be flat. The second adjustment is to adjust the position of the upper end of the connecting screw 44 on the inner wall of the connecting hole 43, further ensuring the flatness of the plate 41. The third adjustment is to adjust the position of the bolt 42 on the inner wall of the lower end of the connecting screw 15, thereby ensuring the flatness of the fixing plate 14. Through these three adjustments, it can adapt to various complex terrains, ensure the flatness of the installation, and achieve good results.

[0053] According to the embodiment of this utility model, an adjustable cultivation container for planting Paeonia lactiflora under forest cover is provided. The threaded plug seat 27 is provided with an L-shaped air passage inside. The two ends of the L-shaped air passage are respectively connected to the air holes 271 opened on the surface and end face of the threaded plug seat 27.

[0054] It should be understood that by setting the L-shaped air passage and air hole 271, the threaded plug seat 27 can also achieve the function of air permeability when it is not completely unscrewed, and the effect is good.

[0055] According to the embodiment of this utility model, an adjustable cultivation container for planting Paeonia lactiflora under forest cover is provided, wherein the surface of the upper cylinder 11 is provided with an annular concave portion 100, and the inner wall of the annular concave portion 100 is provided with an insect-proof ring 200.

[0058] It should be noted that the inner diameter of the threaded cylinder 21 is the same as the inner diameter of the lower cylinder 12.

[0059] It should be understood that the slider and groove design ensures that the feed plate 22 can descend stably and vertically along the inner wall of the threaded cylinder 21 and the lower cylinder 12 under the drive of the threaded screw 23, resulting in good performance.

[0060] According to the embodiment of this utility model, the adjustable cultivation container for planting Paeonia lactiflora under forest cover is provided with a dust filter screen on the top of the annular water collection seat 31, and a feeding port with a sealing cover is provided on the top of the pH adjustment box 32 and the nutrient box 33.

The end of the conduit extending into the soil is a telescopic structure, and the end is provided with a detachable drip head with drip holes of different pore sizes.

[0061] It should be understood that the dust filter can effectively prevent impurities from falling into the annular water collection base 31, avoiding pipe blockage. The feed port with a sealed cap facilitates feeding and effectively prevents evaporation. Water, conditioning solution, and nutrient solution can be quantitatively injected into the soil through the conduit with a regulating valve. The end of the conduit extending into the soil is a telescopic structure, and the end is equipped with a detachable dripper with drip holes of different diameters. The telescopic structure can adjust the installation position of the detachable dripper. The detachable dripper with drip holes of different diameters can control the drainage efficiency according to the actual growth conditions, achieving on-demand adjustment and good performance.
