Description

Technical Field

[0001] This utility model relates to the field of planting technology in saline-alkali land, specifically to an in-situ self-degradable planting cup suitable for severely saline-alkali land. Background Technology

[0002] Saline-alkali soils, due to their high salt content and imbalanced pH, make it difficult for most plant seeds to germinate, resulting in low emergence and seedling survival rates. Plants with poor salt tolerance are particularly vulnerable to stunted growth in saline-alkali soils. Current methods for improving saline-alkali soils often involve large-scale irrigation to leach salt and the application of soil conditioners, which are costly, time-consuming, and yield uneven results. In arid and semi-arid regions, there is often insufficient water supply. Some planting devices use non-biodegradable materials, which can easily cause soil pollution with long-term use and fail to provide a suitable microenvironment for seed germination. Existing planting containers do not fully consider the characteristics of saline-alkali soils, either lacking specific salt-alkali resistant designs or having poor degradation capabilities, failing to meet the core requirements of both environmental friendliness and improved germination rates.

[0003] Publication number CN220674534U discloses a planting cup, including a stepped portion and a foot portion. The stepped portion forms a planting space and includes at least two steps, each with a decreasing diameter. The foot portion connects to the smallest diameter step of the stepped portion, and the diameter of the foot portion is smaller than the diameter of the connected step. A flange is provided on the largest diameter step. By adjusting the relative position of the steps and the seedling tray during seedling cultivation, the planting cup can adapt to different stages of seedling cultivation, eliminating the need to replace the planting cup at different stages, thus improving seedling efficiency and reducing costs. Due to the design of the steps and flange, a robot can easily grasp the planting cup regardless of its position.

[0004] However, when carrying and transporting, the shaking of the cup can easily cause the internal substrate soil to scatter. When sowing, the seeds need to be covered with soil manually, which is inconvenient for sealing the inside and adjusting the sowing height. In addition, in order to ensure the flow of water and air inside the cup, small particles of substrate soil are easy to leak out, which is inconvenient for providing a barrier and air circulation for the substrate soil. Utility Model Content

[0005] The purpose of this invention is to provide an in-situ self-degradable planting cup suitable for severely saline-alkali land, in order to solve the technical problems in the background technology that "the shaking of the cup body easily causes the internal substrate soil to scatter, and the seeds need to be manually covered with soil during sowing, which is inconvenient to seal the inside and adjust the seed sowing height. In addition, in order to ensure the water and air circulation inside the cup, small particles of substrate soil are easy to leak out, which is inconvenient to provide obstruction and air circulation for the substrate soil".

[0006] To achieve the above objectives, this utility model provides the following technical solution: An in-situ self-degrading planting cup suitable for severely saline-alkali land includes a cup body, a sealing assembly installed on the top of the cup body, and a leak-proof assembly installed on the outside of the cup body. The sealing assembly includes a top cover, a positioning cylinder, and a guide post. The top cover is installed on the top of the cup body, the positioning cylinder extends through the top of the top cover, and the guide post is inserted into the inside of the positioning cylinder. A first screw cap is installed on the top of the positioning cylinder, and a second screw cap is fixedly installed on the top of the guide post.

[0007] Preferably, the diameter of the top of the cup body is larger than the diameter of the bottom, and the top cover is threadedly connected to the top of the cup body.

[0008] Preferably, the positioning cylinder slides through the top of the top cover, and the first cap is threadedly connected to the top of the top cover.

[0009] Preferably, the guide posts are inserted into the interior of the positioning cylinder and matched with each other, and the top of the second cap and the first cap are connected by a thread.

[0011] Preferably, the leak-proof cylinder is configured in a semi-funnel shape, with the opening diameter at the top of the leak-proof cylinder being larger than the diameter at the bottom.

[0012] Preferably, the plurality of through holes and the plurality of leak-proof cylinders are arranged in a circumferential manner, with each leak-proof cylinder corresponding to each through hole.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1) The self-degradable planting cup has a top cover that is threaded to the top of the cup body. The positioning tube is inserted into the top of the top cover, and the guide post is inserted into the positioning tube to prevent the substrate soil from scattering when the cup is carried and transported. The positioning tube facilitates rapid seed sowing and allows the substrate soil to automatically cover the seeds to a specified height inside, reducing manual soil covering operations.

[0014] 2) This self-degradable planting cup has the substrate soil inside the cup. Through the through holes and the leak-proof cylinder, air and water flow are provided inside the cup. At the same time, it can block small particles of substrate soil and reduce the leakage of substrate soil. When the cup is placed in the hole of saline-alkali soil, the leak-proof cylinder opens the hole of saline-alkali soil to prevent the saline-alkali soil from expanding and pushing the cup out, increasing the contact area between the soil and the cup. The cup can completely degrade according to the growth of the seedling root system. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1 Combination Figures 1-4 An in-situ self-degradable planting cup suitable for severely saline-alkali land includes a cup body 1, a sealing component 2 installed on the top of the cup body 1, and a leak-proof component 3 installed on the outside of the cup body 1.

[0019] See Figure 2 Furthermore, the sealing assembly 2 includes a top cover 4, a positioning cylinder 5, and a guide post 6. The top cover 4 is installed on the top of the cup body 1. The positioning cylinder 5 passes through the top of the top cover 4. The guide post 6 is inserted into the inside of the positioning cylinder 5. A first screw cap 7 is installed on the top of the positioning cylinder 5. A second screw cap 8 is fixedly installed on the top of the guide post 6. The cup body 1 and the leak-proof cylinder 10 are both made of self-degradable materials. The raw materials used in the preparation of the cup body 1 mainly include one or more of the following: straw degradable materials, paper, starch-based materials, and biodegradable plastics. The inside of the cup body 1 is used to fill the substrate soil, and the substrate soil is used to place seeds.

[0020] The diameter of the top of the cup body 1 is larger than the diameter of the bottom. The top cover 4 is threadedly connected to the top of the cup body 1 and is used for sealing the inside of the cup body 1.

[0021] The positioning cylinder 5 is slidably disposed through the top of the top cover 4, and the first screw cap 7 is threadedly connected to the top of the top cover 4. The positioning cylinder 5 is used to position the seed height and is fixedly connected to the top cover 4 through the first screw cap 7.

[0022] The guide post 6 is inserted into the inside of the positioning cylinder 5 and matches each other. The top of the second cap 8 and the first cap 7 are connected by a thread. The guide post 6 is used to fill the inside of the positioning cylinder 5 to prevent the substrate soil from entering.

[0023] Specifically, the top cover 4 is threaded to the top of the cup body 1, the positioning cylinder 5 is inserted into the top of the top cover 4, and the guide post 6 is inserted into the positioning cylinder 5 to prevent the substrate soil from scattering when the cup body 1 is carried and transported. The positioning cylinder 5 facilitates rapid seed sowing and enables the substrate soil to automatically cover the seeds at a specified height inside, reducing manual soil covering operations.

[0024] Example 2 See Figure 3 Furthermore, based on Embodiment 1, the leak-proof component 3 includes several through holes 9 and several leak-proof cylinders 10. The several through holes 9 penetrate the inner and outer walls of the cup body 1, and the several leak-proof cylinders 10 are respectively fixedly installed on the outside of each through hole 9.

[0025] The leak-proof cylinder 10 is set in a semi-funnel shape. The opening diameter at the top of the leak-proof cylinder 10 is larger than the diameter at the bottom. The leak-proof cylinder 10 opens up the holes in the saline-alkali land, making it easier to place the cup body 1.

[0026] Several through holes 9 and several leak-proof cylinders 10 are arranged in a circle. Each leak-proof cylinder 10 corresponds to each through hole 9. The through holes 9 are used for the flow of air and water inside the cup body 1, and the leak-proof cylinders 10 reduce the leakage of substrate soil.

[0027] Specifically, the substrate soil is located inside the cup body 1. Through the through hole 9 and the leak-proof cylinder 10, air and water flow are provided inside the cup body 1. At the same time, it can block small particles of substrate soil and reduce the leakage of substrate soil. When the cup body 1 is placed in the hole of saline-alkali land, the leak-proof cylinder 10 opens the hole of saline-alkali land to prevent the thermal expansion of saline-alkali land soil from pushing the cup body 1 out, increasing the contact area between the soil and the cup body 1. The cup body 1 can be completely degraded according to the growth of the seedling root system.

[0028] In actual operation, first, make a hole in the saline-alkali land according to the size of cup 1, with the hole depth slightly greater than the height of cup 1. Place cup 1 into the hole so that the top of cup 1 is flush with the ground surface. No additional soil covering is required. Cup 1 isolates the high-salt soil and water of the saline-alkali land. The substrate is filled in cup 1 and is mainly composed of decomposed plant straw, organic fertilizer, peat and sand mixture and salt-alkali tolerant microbial agent mixed in proportion. It is used to provide nutrients for seeds, retain water environment and salt-alkali resistant micro-ecology. Seeds germinate smoothly in the substrate. During the seedling growth process, cup 1 gradually degrades. Seedling roots can penetrate the degraded cup 1 and extend into the saline-alkali soil. At this time, the seedling has a certain resistance ability and can continue to grow in the improved soil environment. When sealing and planting, the substrate soil is filled into the cup body 1, the top cover 4 is connected to the top of the cup body 1 by threads, the positioning cylinder 5 is inserted into the top of the top cover 4, and the guide post 6 is inserted into the positioning cylinder 5. They are connected and fixed by the threads of the first screw cap 7 and the second screw cap 8. When placing seeds and planting, the positioning cylinder 5 opens the substrate soil, the guide post 6 is taken out, and the seeds are placed in the substrate soil through the positioning cylinder 5. By removing the positioning cylinder 5 from the substrate soil, the substrate soil automatically covers the seeds to the specified height inside, reducing the manual soil covering operation. During the leak prevention process, the substrate soil is located inside the cup body 1. Small particles of substrate soil are blocked by the leak prevention cylinder 10, reducing the leakage of substrate soil. Through the through hole 9 and the leak prevention cylinder 10, air and water flow are provided inside the cup body 1 while preventing leakage. When the cup body 1 is placed in the hole of the saline-alkali land, the leak prevention cylinder 10 opens the hole of the saline-alkali land to prevent the thermal expansion of the saline-alkali land soil from pushing the cup body 1 out. The saline-alkali land soil enters into the leak prevention cylinder 10, increasing the contact area between the soil and the cup body 1. The cup body 1 can be completely degraded according to the growth of the seedling root system.
