Description

Technical Field

[0001] This invention belongs to the field of Uncaria rhynchophylla cultivation technology, specifically a method for cultivating Uncaria rhynchophylla to restore karst mountain areas. Background Technology

[0002] Vegetation restoration and afforestation are important restoration methods in damaged karst mountain areas. Selecting native plants adapted to local soil and climate conditions, such as herbaceous plants, shrubs and trees, can help control soil erosion, maintain soil stability and restore ecosystem functions.

[0003] Karst mountains are mostly distributed in provinces such as Guangxi, Yunnan, and Guizhou, and Uncaria rhynchophylla is suitable for growing in these provinces. Therefore, existing technologies utilize Uncaria rhynchophylla to restore karst mountains. For example, Chinese patent document CN108834774B describes a method for cultivating Uncaria rhynchophylla to restore karst mountains. By cultivating Uncaria rhynchophylla in karst mountains, water retention and moisture preservation are achieved, and the appropriate soil depth covering the Uncaria rhynchophylla seedlings is ensured, thereby improving the survival rate of transplanted Uncaria rhynchophylla seedlings and the yield of medicinal materials, and increasing the vegetation coverage of karst mountains.

[0004] In the process of restoring karst mountains with Uncaria rhynchophylla, the main method is to use the root system of Uncaria rhynchophylla to restore the surface soil of karst mountains. Uncaria rhynchophylla is usually planted on slopes to promote its absorption of sunlight. Its root system mostly extends along the slope direction. However, due to the certain spacing between Uncaria rhynchophylla plants, some slope soil areas are difficult to be covered by the Uncaria rhynchophylla root system. Summary of the Invention

[0005] The purpose of this invention is to provide a method for cultivating Uncaria rhynchophylla to restore karst mountain areas. This method can effectively guide the roots of Uncaria rhynchophylla, making the roots more evenly distributed in the cultivated slope, thereby enhancing the soil restoration effect on karst mountain areas.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: A method for cultivating Uncaria rhynchophylla to restore karst mountain areas, comprising the following steps:

[0007] S1: Land preparation: Select a sunny slope, remove weeds from the slope surface, loosen the soil in areas with compacted soil, and spread fertilizer on the slope surface after removing weeds.

[0008] S2 Assembly: Prepare cultivation tubes that match the slope angle after land preparation. Fill the cultivation tubes with perlite, nutrient soil, humus and local soil in sequence, and bury the Uncaria seeds in the humus.

[0009] S3 cultivation: Insert the assembled cultivation tubes into the prepared slope soil at equal intervals, and then spray fertilizer again. The cultivation tubes will temporarily store the fertilizer and gradually transport it in the opposite direction of the slope.

[0010] S4 mulching: Cover the slope surface after cultivation with non-woven fabric, and fix the non-woven fabric at multiple points;

[0011] S5 Management: Conduct appropriate post-planting management based on the growth status of Uncaria rhynchophylla.

[0012] Furthermore, post-management includes:

[0013] Replenishment: Check the condition of Uncaria seedlings in each cultivation tube and directly replace the cultivation tubes with missing seedlings;

[0014] Topdressing: Apply additional fertilizer according to the climate and the soil conditions of the slope where Uncaria rhynchophylla is cultivated;

[0015] Pest and disease control: Spray pesticides on the Uncaria rhynchophylla that are affected by pests and diseases according to its growth status.

[0016] Furthermore, post-treatment management also includes regular topdressing:

[0017] Spring: Apply compound fertilizer once, at a rate of 1 kg / 100 plants;

[0018] In autumn and winter: Apply farmyard manure once, in an appropriate amount.

[0019] Furthermore, the slope of the hillside ranges from 20° to 45°.

[0020] Furthermore, the nonwoven fabric is secured using biodegradable fasteners.

[0021] Furthermore, the assembled cultivation tube is vertically inserted into the soil of the slope, with the top opening of the cultivation tube flush with the surface of the soil.

[0022] Furthermore, the cultivation tube includes an outer tube body, with several fixing openings on the lower side wall of the outer tube body and several through holes on the remaining side walls of the outer tube body. An inner tube body is slidably fitted to the inner side wall of the outer tube body. The inner tube body is hollow inside and also has several through holes on its side walls. A fixing buckle is provided on the lower side wall of the inner tube body, extending into the fixing opening. After being squeezed and deformed, the fixing buckle extends outward from the fixing opening. The diameter of the opening at the upper end of the outer tube body gradually increases. A closed ring composed of multiple bimetallic sheets is fixedly connected between the outer side wall of the inner tube body and the inner side wall of the outer tube body. The closed ring is arranged at an angle. The closed ring, the inner tube body, and the upper opening of the outer tube body form an accommodating space. A capillary rope is provided in the inner tube body, with both ends of the capillary rope extending into the accommodating space and the fixing buckle, respectively.

[0023] Furthermore, the bottom of the outer tube is a solid conical structure, and the top of the inner tube is integrally formed with a flange.

[0024] Furthermore, both the outer and inner tubes are made of biodegradable materials.

[0025] Furthermore, the angle between the closed loop and the slope is equal to the slope of the slope.

[0026] The above approach has the following beneficial effects:

[0027] 1. In this method, Uncaria rhynchophylla seeds are assembled into cultivation tubes for cultivation. After the cultivation tubes are fixed into the soil of the slope, the inner tube is dragged, causing the fixing buckles on the inner tube to be squeezed outwards within the fixing opening. The fixing buckles can increase the fixing effect of the cultivation tubes, while the capillary rope is introduced into the soil of the slope.

[0028] The cultivation tubes temporarily store applied fertilizer and rainwater, preventing them from rapidly washing away with the slope. Because the angle between the closed ring and the slope is equal to the slope's gradient (i.e., the closed ring remains horizontal), the fertilizer and rainwater within the storage space do not tilt towards the slope's side. Furthermore, capillary ropes siphon the fertilizer and rainwater into the surrounding soil, ensuring that the soil around the cultivation tube retains both fertilizer and water. The roots of the Uncaria rhynchophylla then disperse and grow around the cultivation tube as the fertilizer and rainwater are distributed. Compared to existing technologies, this method solves the problem of Uncaria rhynchophylla's roots tending to extend too far down the slope and not spreading sufficiently when cultivated on slopes, thus improving the restoration effect of Uncaria rhynchophylla on karst mountain areas.

[0029] 2. In this scheme, when Uncaria rhynchophylla is cultivated outdoors, it cannot completely cover the cultivation tube during its immature stage. When the outdoor temperature reaches its deformation temperature, the bimetallic strip on the closed ring will deform, causing the fertilizer and rainwater in the solute space to converge to one side. This promotes the rapid siphoning of fertilizer and rainwater into the soil around the cultivation tube by the capillary rope, preventing the fertilizer and rainwater from evaporating. When the bimetallic strip is not deformed, the capillary rope slowly siphons fertilizer and rainwater into the soil around the cultivation tube, allowing the soil around the cultivation tube to retain fertilizer and moisture for a longer period of time.

[0030] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0038] In the description of this invention, unless otherwise specified and limited, it should be noted that the terms "installation", "connection" and "linking" should be interpreted broadly. For example, they can refer to mechanical or electrical connections, or internal connections between two components. They can be direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0039] The following detailed description illustrates the specific implementation method:

[0040] The reference numerals in the accompanying drawings of the instruction manual include: outer tube 1, inner tube 2, flange 3, closing ring 4, capillary rope 5, through hole 6, sealing film 7, fixing buckle 8, non-woven fabric 9. Example

[0041] As attached Figure 1 The following is a method for cultivating Uncaria rhynchophylla to restore karst mountain areas, comprising the following steps:

[0042] S1: Land preparation: Select a sunny slope, remove weeds from the slope surface, loosen the soil in areas with compacted soil, and spread fertilizer on the slope surface after weed removal.

[0043] When selecting a slope, choosing a slope with longer periods of sunlight can effectively promote the growth and development of Uncaria rhynchophylla, allowing it to mature as quickly as possible. The slope should ideally be between 20° and 45° to effectively improve the survival rate of Uncaria rhynchophylla cultivation.

[0044] S2 Assembly: Prepare cultivation tubes that match the slope angle after land preparation. Fill the cultivation tubes with perlite, nutrient soil, humus and local soil in sequence, and bury the Uncaria seeds in the humus.

[0045] Combined with appendix Figure 3-4 As shown, the cultivation tube includes an outer tube 1. The lower side wall of the outer tube 1 has two sets of fixing ports, which are divided into two layers. Each layer has four fixing ports, which are evenly distributed around the circumference of the outer tube 1. The other side walls of the outer tube 1 have several through holes 6. The inner tube 2 is slidably fitted to the inner side wall of the outer tube 1. The inner tube 2 is hollow inside and its side walls also have several through holes 6. The lower side wall of the inner tube 2 has an integrally formed fixing buckle. The fixing buckle is made of a deformable biodegradable material. The fixing buckle extends into the fixing port and extends outward from the fixing port after being squeezed and deformed.

[0046] The diameter of the opening at the upper end of the outer tube 1 gradually increases. A closed ring 4 composed of multiple bimetallic sheets is fixedly connected between the outer wall of the inner tube 2 and the inner wall of the outer tube 1. The closed ring 4 is arranged at an angle, and the angle of inclination is set according to the selected slope angle. Preferably, the angle between the closed ring 4 and the slope is equal to the slope of the slope. The closed ring 4, the inner tube 2 and the upper opening of the outer tube 1 form an accommodating space. A capillary rope 5 is provided in the inner tube, and the two ends of the capillary rope 5 extend into the accommodating space and the fixing buckle 8, respectively.

[0047] The bottom of the outer tube 1 is a solid conical structure, and the top of the inner tube 2 is integrally formed with a flange 3. Both the outer tube 1 and the inner tube 2 are made of biodegradable materials.

[0048] When using the cultivation tube, first insert the outer tube into the soil. Then, stretch the inner tube 2 outwards using the flange 3, allowing the fixing buckle to extend into the soil through the fixing opening, thus fixing the entire cultivation tube to the soil. This makes the inner tube 2 higher than the outer tube 1. Waste and rainwater are temporarily stored in the containment space. Fertilizer and rainwater in the containment space are siphoned into the soil around the cultivation tube via capillary rope 5, ensuring that the soil around the cultivation tube can hold both fertilizer and rainwater. Combined with the attached... Figure 3 and attached Figure 4 These are schematic diagrams of the inner tube body under tension and under tension, respectively.

[0049] S3 cultivation: The assembled cultivation tubes are inserted into the prepared slope soil at equal intervals, and fertilizer is applied again. The cultivation tubes temporarily store the fertilizer and gradually transport it in the opposite direction of the slope.

[0050] The assembled cultivation tube is vertically inserted into the soil of the slope, and the opening at the top of the cultivation tube is flush with the surface of the soil on the slope.

[0051] S4 Covering: Cover the slope surface after cultivation with non-woven fabric 9, and fix the non-woven fabric 9 at multiple points selected on the non-woven fabric 9;

[0052] Among them, the non-woven fabric 9 is fixed by biodegradable fixing nails.

[0053] S5 Management: Conduct appropriate post-planting management based on the growth status of Uncaria rhynchophylla.

[0054] Post-management includes:

[0055] Replenishment: Check the condition of Uncaria seedlings in each cultivation tube and directly replace the cultivation tubes with missing seedlings;

[0056] Topdressing: Apply additional fertilizer according to the climate and the soil conditions of the slope where Uncaria rhynchophylla is cultivated;

[0057] Pest and disease control: Spray pesticides on the Uncaria rhynchophylla that are affected by pests and diseases according to its growth status.

[0058] In addition, post-treatment management also includes regular topdressing:

[0059] Spring: Apply compound fertilizer once, at a rate of 1 kg / 100 plants;

[0060] In autumn and winter: Apply farmyard manure once, in an appropriate amount.
