Description

Technical Field

[0001] This utility model belongs to the field of integrated cultivation and breeding technology of traditional Chinese medicine, and specifically relates to a device for intercropping and breeding earthworm and traditional Chinese medicinal materials. Background Technology

[0002] Pheretima aspergillum (E. perrier) is the only animal-derived medicinal herb among the "Ten Delicacies of Guangxi," exhibiting significant efficacy in clearing heat and calming the nerves, promoting blood circulation, relieving asthma, and promoting diuresis. Preliminary research revealed that the land used for artificial breeding of Pheretima aspergillum is mostly agricultural land. Excessive fertilization, watering, and pesticide use, along with simplified planting systems, pose significant challenges to sustainable soil utilization. Furthermore, artificial breeding is largely monoculture, with insufficient utilization of the above-ground parts, resulting in a serious waste of land resources. Therefore, there is an urgent need to leverage resource advantages, adapt to local conditions, and develop a comprehensive ecological integrated farming model for Pheretima aspergillum. This model should form a new, multi-faceted, ecologically efficient integrated farming system to improve the quality and efficiency of breeding bases, enhance agricultural efficiency, and achieve a double harvest of economic and ecological benefits.

[0003] Centella asiatica (L.) Urban, also known as goosegrass, is a typical clonal plant that primarily reproduces asexually and expands its spatially through stolons. Studies have shown that Centella asiatica contains triterpenes and their glycosides, flavonoids, alkaloids, volatile oils, and other active ingredients, giving it high medicinal value. The dried whole plant or the whole plant with roots is used medicinally. It is cold in nature and bitter and pungent in taste, possessing functions of clearing heat and dampness, promoting blood circulation and stopping bleeding, detoxifying and reducing swelling. It is mainly used to treat fever, cough and asthma, sore throat, shingles, traumatic swelling and pain, external bleeding, and snake and insect bites. Furthermore, Centella asiatica has a tender texture and good palatability, making it suitable for raw consumption. In southern my country, it is commonly used in traditional herbal teas. In Southeast Asia, India, Pakistan, Sri Lanka, and South America, Centella asiatica is consumed as a vegetable, demonstrating its good nutritional value. In my country, Centella asiatica has been included in the "List of Items that Can Be Used in Health Foods." However, due to the low yield and difficulty in harvesting wild Centella asiatica, the current demand cannot be met, leading to a continuous rise in the price of Centella asiatica. Furthermore, the content of medicinal components in artificially cultivated Centella asiatica is lower than that in wild Centella asiatica due to the controlled growth environment. The total mass fraction of asiaticoside and hydroxyasiaticoside in Centella asiatica can only reach 1.95%~2.73% (Yao Shaochang, Ming Ruhong, Fu Peng, Pan Dongjin, Jiang Xiangjun, Li Liangbo, Huang Rongshao. Effects of different planting densities on photosynthetic characteristics, yield and quality of Centella asiatica [J]. Guangdong Agricultural Sciences, 2022, 49(7): 16-25). Therefore, the quality of artificially cultivated Centella asiatica needs further improvement.

[0004] In summary, developing an intercropping and interbreeding model of "Centella asiatica + Eriocaulon buergerianum" can form a highly efficient industrial development model for increasing the yield of Eriocaulon buergerianum through intercropping and breeding, achieving a dual improvement in economic and ecological benefits. For example, in patent CN202510698569.8, a method for intercropping and interbreeding Eriocaulon buergerianum and Centella asiatica, the applicant studied the intercropping and interbreeding of Eriocaulon buergerianum and Centella asiatica. In this model, areas with sufficient water and convenient drainage are selected as the planting and breeding areas. Shading nets with a 30% shading degree are used to enclose the planting and breeding areas to form planting and breeding sheds. Inside the planting and breeding sheds, non-woven fabric is used to enclose planting and breeding devices of the required size as individual planting and breeding units. Each planting and breeding unit is filled with substrate for intercropping and breeding Centella asiatica and Eriocaulon buergerianum. The non-woven fabric can prevent the Eriocaulon buergerianum from escaping. The above-mentioned planting and breeding device has the following disadvantages: since non-woven fabric is used to form individual planting and breeding units, it is relatively easy to harvest Centella asiatica, but it is more difficult to harvest Pheretima aspergillum. Utility Model Content

[0005] The purpose of this invention is to provide a device for intercropping and cultivating *Pheretima aspergillum* and medicinal herbs, thereby solving the problem of how to easily harvest *Pheretima aspergillum* during the intercropping and cultivation process. The specific technical solution is as follows: A device for intercropping and raising earthworm and Chinese medicinal herbs includes a breeding box, a first through hole at the bottom of the breeding box, a migration channel box below the breeding box, an inclined part formed inside the migration channel box, the high end of the inclined part being located below the first through hole, the low end of the inclined part being connected to the inner bottom surface of the migration channel box, and a second through hole at the bottom of the migration channel box. A collection box is provided below the migration channel box, and a non-woven fabric is provided between the collection box and the migration channel box. The non-woven fabric is detachably connected to the breeding box and can cover the second through hole.

[0006] Preferably, the migration channel box is mounted on a support body, and the support body is provided with a third through hole, which corresponds to the second through hole, so that the third through hole and the second through hole are interconnected. The collection box is located below the support, and the non-woven fabric is located between the support and the collection box.

[0007] Preferably, a plurality of migration channel boxes are provided below the breeding box, and the first through hole is provided in the breeding box corresponding to the high end of the inclined part of each migration channel box.

[0008] Preferably, the breeding box, the migration channel box, and the collection box are all made of wood.

[0009] Preferably, the lower end of the support body is connected to a support column, which can support the support body on the ground.

The embodiments of this utility model will now be described based on its overall structure.

[0020] See Figures 1-4 A device for intercropping and raising earthworm and Chinese medicinal herbs includes a breeding box 1, a first through hole 10 at the bottom of the breeding box 1, a migration channel box 2 below the breeding box 1, an inclined part 21 formed inside the migration channel box 2, the high end of the inclined part 21 being located below the first through hole 10, the low end of the inclined part 21 being connected to the inner bottom surface of the migration channel box 2, and a second through hole 20 at the bottom of the migration channel box 2.

[0021] A collection box 3 is provided below the migration channel box 2. A non-woven fabric 4 is provided between the collection box 3 and the migration channel box 2. The non-woven fabric 4 is detachably connected to the breeding box 1 and can cover the second through hole 20. The breeding box 1 is equipped with a substrate for intercropping and raising earthworms and Chinese medicinal herbs. The substrate is mainly composed of garden soil, pond mud and peat soil.

[0022] In this embodiment, when using this device for intercropping and raising earthworms and medicinal herbs, the device is set up inside a cultivation shed, which is equipped with a shade net. Substrate is placed in the cultivation box 1 to a depth of 35-40cm. Then, the medicinal herbs (Centella asiatica) are transplanted into the substrate. After transplanting, cow dung is piled between the rows of medicinal herbs (Centella asiatica), and then earthworm seedlings are introduced onto the cow dung. The seedlings enter the cow dung to feed and then into the substrate. During the cultivation process, water is applied every two days, ensuring thorough watering each time. Cow dung is added weekly, and compound microorganisms and growth promoters are applied to the roots during the vigorous growth period of Centella asiatica. Centella asiatica and earthworms are harvested after 3 or 3.5 months of cultivation.

[0023] In this embodiment, the top surface of the migration channel box 2 contacts the bottom surface of the breeding box 1, allowing the breeding box 1 to be supported on the migration channel box 2. A non-woven fabric 4 is disposed between the top surface of the collection box 3 and the bottom surface of the migration channel box 2, and the non-woven fabric 4 is configured to be removable between the top surface of the collection box 3 and the bottom surface of the migration channel box 2. The migration channel box 2 is supported on the collection box 3.

[0024] In this embodiment, during intercropping and interbreeding, the collection box 3 is first placed directly on the ground, and the migration channel box 2 is then placed on top of the collection box 3. Simultaneously, the breeding box 1 is placed on top of the migration channel box 2. The weight of the substrate inside the breeding box 1 presses the breeding box 1 and the migration channel box 2 onto the collection box 3. Furthermore, to facilitate the removal of the collection box 3, support blocks can be used to support the sides of the breeding box 1 before it can be removed.

[0025] See Figure 5 , Figure 5 (a) is a schematic diagram of the device when *Centella asiatica* and *Centella asiatica* are intercropped and intercultured. Figure 5(b) is a schematic diagram of the device during the harvesting of *Echinochloa crus-galli* and *Centella asiatica* intercropping. In this embodiment, an inclined section 21 is formed inside the migration channel box 2, with the high end of the inclined section 21 positioned below the first through hole 10. The low end of the inclined section 21 is connected to the inner bottom surface of the migration channel box 2, and a second through hole 20 is opened inside the migration channel box 2 on the low end side of the inclined section 21. The inclined surface of the inclined section 21 forms a channel for *Echinochloa crus-galli* to crawl through.

[0026] See Figure 5 In (a) and (b), during intercropping and interbreeding, the second through-hole 20 is covered with non-woven fabric 4 to prevent the earthworm from passing through the second through-hole 20, and no substrate is placed in the migration channel box 2. The behavior of earthworms includes attraction to darkness, moisture, food sources, and crawling ability. During the intercropping and interbreeding stage, the breeding box 1 is filled with substrate. The environment inside the breeding box 1 is humid, has food (decomposed organic matter in the substrate), and is protected from light. Taking advantage of the earthworm's behavior, even if the earthworm enters the migration channel box 2 through the first through-hole 10 on the breeding box 1, it will instinctively move towards a more humid direction with food smells. That is, the earthworm will crawl along the inclined surface of the inclined part 21 and then burrow into the substrate in the breeding box 1 through the first through-hole 10.

[0027] During the harvesting stage, first harvest the Centella asiatica. After picking the Centella asiatica from the substrate on breeding box 1, remove the non-woven fabric 4 between migration channel box 2 and collection box 3, exposing breeding box 1 to sunlight. Simultaneously, stop adding water and cow manure to the substrate for 3-5 days (the duration can be determined by the breeder based on the actual condition of the substrate). This series of operations completely changes the environment inside breeding box 1. Sunlight breaks the original shaded conditions, and the substrate gradually dries out due to the cessation of watering, lacking moisture. The cessation of cow manure addition and continued consumption reduces the amount of decomposed organic matter in the substrate, ultimately transforming breeding box 1 from a suitable habitat for the earthworm into an unsuitable environment (humid, dark, and rich in food), forcing the earthworm to actively seek a more suitable living space. Simultaneously, add substrate and cow manure to collection box 3 to create an ideal environment with moisture and food. The substrate here needs to be sprayed with water beforehand to adjust humidity, ensuring it can be formed into a clump by hand but crumbles easily when released, matching the earthworm's preference for moisture. The fresh cow dung mixed in undergoes preliminary decomposition, continuously releasing the food scents that the groundhog cichlids are sensitive to, matching their instinct to attract food sources. Collection box 3 is originally located at the lower end of migration channel box 2, which covers the upper part of collection box 3. The upper opening of collection box 3 is not directly exposed to sunlight, naturally maintaining a light-protected state, matching their preference for darkness, making collection box 3 the optimal destination for groundhog cichlid migration. Thus, the groundhog cichlids enter migration channel box 2 through the first through-hole 10 of breeding box 1, and then enter collection box 3 through the second through-hole 20 on migration channel box 2.

[0028] The entire harvesting process utilizes environmental gradients to induce the active migration of *Echinochloa crus-galli*. Migration channel box 2 acts as a crucial transition zone. During the harvesting stage, rearing box 1 is exposed to direct sunlight, with watering and feeding stopped, making its interior dry, bright, and food-scarce—creating an uninhabitable zone for *Echinochloa crus-galli* (dry, light, food shortage). Simultaneously, collection box 3 is prepared with moist substrate and fresh cow manure, creating an ideal zone that is dark, humid, and rich in food. A significant environmental difference exists between these two zones. Although migration channel box 2 itself does not contain substrate, its internal environment, especially the surface of the inclined section 21, remains relatively moist due to residual moisture in rearing box 1 and moisture evaporating from collection box 3 below. This humid microenvironment strongly attracts *Echinochloa crus-galli* descending from the dry upper layer, aligning with its hygroscopic behavior. Therefore, after entering migration channel box 2 from rearing box 1, *Echinochloa crus-galli* is not only physically guided by the inclined surface but also biochemically attracted by the moisture, food odors, and darkness from collection box 3 below. This multi-sensory, multi-layered induction enabled the Guangdilong to migrate downwards actively and with a clear goal, thus ensuring extremely high migration efficiency and biological activity.

[0029] During the harvesting stage, after the non-woven fabric 4 is removed, the enclosed structure of the migration channel box 2 provides crucial protection for the migrating earthworms. During migration, the earthworms are exposed and move relatively slowly, making them highly susceptible to external environmental disturbances. The side walls of the migration channel box 2 effectively block strong winds and sunlight, providing a safe migration corridor for the earthworms. This protection is essential for maintaining the physiological stability of the earthworms during migration and reducing stress responses. A low-stress migration process helps maintain the activity and health of the earthworms, which is beneficial for their quality as a traditional Chinese medicine and for potential subsequent re-cultivation.

[0030] The enclosed structure of the migration channel box 2 also helps maintain the relative stability of its internal microenvironment. During the harvesting stage, although the rearing box 1 becomes dry, the moisture and food odor in the collection box 3 can diffuse upwards through the second through-hole 20, forming a humidity, temperature, and chemical odor gradient within the migration channel box 2. This stable microenvironment is highly attractive to earthworms, continuously guiding them downwards. In a completely open system, this moisture and odor would quickly dissipate into the surrounding air, failing to form an effective and continuous induction gradient between the rearing box 1 and the collection box 3. The physical boundary of the migration channel box 2 effectively locks these induction signals, allowing them to act concentratedly on the earthworms within the channel, thus ensuring the persistence and efficiency of the induction effect. Compared to many traditional earthworm separation methods such as mechanical sieving and strong light repellency, the device provided by this invention can reduce the stress and damage to earthworms, achieving a harvesting process through environmental induction and natural aggregation.

[0031] It should be noted that the depth of collection box 3 should be set to 5-10cm. A very deep collection box 3 is unnecessary. In a shallow collection box 3, the substrate only needs to fill the box during harvest, with a depth of 5-8cm, far less than the 35-40cm depth required in breeding box 1. With a shallow substrate setting in collection box 3, once the earthworms enter, the shallow substrate layer does not require deep digging. Workers can easily and completely separate the earthworms by gently removing the surface substrate, greatly reducing harvesting difficulty, minimizing damage to the earthworms, saving harvesting time, and improving overall breeding efficiency. The substrate in collection box 3 can be reused in breeding box 1 or retained in collection box 3 for the next earthworm harvest. When reused, it can be moistened again and supplemented with earthworm food.

[0032] In a preferred embodiment, the migration channel box 2 is mounted on a support body 5, and the support body 5 has a third through hole 50 corresponding to the second through hole 20, such that the third through hole 50 and the second through hole 20 are interconnected. The collection box 3 is positioned below the support body 5, and the non-woven fabric 4 is positioned between the support body 5 and the collection box 3. A support column 6 is connected to the lower end of the collection box 3, and the support column 5 supports the collection box 3 on the ground.

[0033] The lower end of the support body 5 is connected to a support column 7, which can support the support body 5 on the ground.

[0034] The support body 5 is used to support the migration channel box 2, and then to support the breeding box 1, so that the space between the breeding box 1 and the ground can be used to install the collection box 3. When installing the collection box 3, the top surface of the collection box 3 is in contact with the bottom surface of the support body 5, and the bottom surface of the support body 5 is used to close the opening at the top of the collection box 3. The third through hole 50 on the support body 5 is connected to the collection box 3, so that the earthworm can enter the collection box 3 through the third through hole 50.

[0035] The nonwoven fabric 4 is positioned between the support body 5 and the collection box 3 to seal the third through hole 50 during the intercropping and interbreeding stage. The nonwoven fabric 4 is also removed during the harvesting stage of the earthworms.

[0036] In a preferred embodiment, a plurality of migration channel boxes 2 are provided below the breeding box 1, and the first through hole 10 is provided above the high end of the inclined part 21 in each migration channel box 3.

[0037] In the existing intercropping and interbreeding process, a single planting and breeding device is enclosed by non-woven fabric, with an area of ​​0.24m². 2 ~0.4m 2 Each planting and breeding device can only intercrop 9-12 Centella asiatica plants. If you want to reduce the number of planting and breeding devices, you need to increase the area of ​​each individual planting and breeding device so that each planting and breeding device can intercrop more Centella asiatica plants.

[0038] The inclination of migration channel box 2 should be set at 4-5°, and its depth and volume should not be too large. Excessive volume increases the migration distance of the earthworms, hindering environmental induction. Therefore, when increasing the area of ​​breeding box 1, multiple migration channel boxes 2 are needed. Earthworms primarily perceive suitable environments through humidity and food odor. A single migration channel box 2 can only create a localized induction gradient at the bottom of breeding box 1. Earthworms in the edge areas, due to the distance, have difficulty sensing the moisture and food signals from collection box 3 and are prone to remaining in the substrate. Multiple migration channel boxes 2 can create multi-point induction at the bottom of breeding box 1. Even earthworms at the edge of breeding box 1 can quickly sense the suitable signals of the nearest channel and actively move towards the channel, significantly improving the harvest in the edge areas.

[0039] It should be noted that the first through-hole 10 of the breeding box 1 at the upper end of the migration channel box 2 will be filled with substrate due to the weight of the substrate in the breeding box 1. A small amount of this substrate will also fall into the migration channel box 2, but it will not completely fill the migration channel box 2. Only a small amount of substrate will accumulate below the first through-hole 10. When water is poured into the breeding box 1, the water will moisten the substrate in the breeding box 1, and some water will seep into the migration channel box 2, but it will not fill the migration channel box 2 with water. This is because most of the water is used to moisten the substrate in the breeding box 1 from top to bottom. Therefore, the migration channel box 2 serves as a transition zone, containing a small amount of substrate and a relatively moist environment, rather than a rigid cavity. The small amount of substrate itself carries the microorganisms and odors from the breeding box 1, which can mix with the new odors coming from the collection box 3 below, reducing the alertness and stress response of the earthworms and forming a continuous and guiding odor gradient.

[0040] In a preferred embodiment, the breeding box 3, the migration channel box 2, and the collection box 3 are all made of wood. Wood naturally releases a faint, earthy aroma, which mainly comes from lignin, cellulose, natural resins, and terpenoids. Compared to the smell of plastic or metal, the natural aroma of wood effectively reduces stress levels in earthworms, thereby promoting their feeding, growth, and reproduction.

[0041] In a preferred embodiment, fermented cow manure, treated rotten vegetable leaves, and watermelon rind plant materials, along with some substrate, are placed in the collection box 3. The treated cow manure is spread evenly on the top layer of the collection box 3. When harvesting the Centella asiatica, no more cow manure is added. The food in the breeding box 3 is already scarce. With food in the collection box 3, the animals are guided to the collection box 3 by their attraction to food, moisture, and darkness. Of course, since there is substrate in the breeding box 1, a very small number of individual earthworms may remain in the breeding box 1 due to specific physiological states or behavioral delays. These can be replanted with new Centella asiatica. However, the vast majority of earthworms will be induced to the collection box 3 for harvesting.

[0042] In summary, the present invention provides a device for intercropping and raising ground worms and Chinese medicinal herbs, which utilizes the habits of ground worms for environmental induction and harvests ground worms during the intercropping and raising of Chinese medicinal herbs. The device is simple and practical.
