Description

Technical Field

[0001] The invention belongs to the technical field of earthworm breeding, and particularly relates to a field earthworm seedling throwing device and an earthworm seedling throwing breeding method. Background Art

[0002] With the rapid development of the economy, a large amount of organic waste has been generated. Treating the waste by breeding earthworms not only solves the problem of waste disposal but also can obtain very good economic benefits.

[0003] At present, earthworm farming relies on the natural spawning of earthworms and natural hatching in breeding beds, which has the problems of long hatching time and low hatching rate. Alternatively, the earthworm seedlings are placed on the breeding beds. Due to the obvious difference between the hatching environment and the environment in the breeding beds, the survival rate of the earthworm seedlings is low. At the same time, there are pests such as mole crickets and grubs in the breeding beds, and there are natural enemies such as rats, birds, and ants around the breeding beds that will devour the earthworm larvae in large quantities, seriously restricting the benefits of earthworm farming.

[0004] Therefore, there is an urgent need for a device for throwing earthworm seedlings and a method for throwing earthworm seedlings to improve the survival rate of earthworm seedlings. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a field earthworm seedling planting device and an earthworm seedling planting breeding method, which can increase the survival rate of earthworm seedlings, shorten the breeding cycle, and improve the breeding efficiency.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] A field earthworm seedling planting device comprises a placing tube and a drainage tank connected to the placing tube, wherein the placing tube comprises an incubation tube and a sedimentation tube arranged up and down, a sealing water-permeable net is arranged at the lower opening of the incubation tube, a plurality of holes are arranged around the incubation tube, and a gauze net is arranged on the holes, a filter is arranged in the sedimentation tube, the filter is connected to the drainage tank through a pipeline, and the drainage tank is connected to a vacuum pump through a pipeline.

[0008] A further improvement of the technical solution of the present invention is that the incubation tube and the deposition tube are movably connected, and the aperture of the gauze covering the holes on the upper part of the incubation tube decreases from top to bottom along the length direction of the incubation tube.

[0009] A further improvement of the technical solution of the present invention is that: the sedimentation tube is in a conical shape, a water level sensor is arranged at the upper part of the sedimentation tube, and the filter is a ceramic filter in an elongated strip shape and is arranged vertically in the sedimentation tube.

[0010] A further improvement of the technical solution of the present invention is that the aperture of the water-permeable net is 0.1-0.2mm, the aperture of the gauze used for sealing the top of the incubation tube is 0.1-0.2mm, 2-4 layers of holes are arranged on the incubation tube, the diameter of the holes is 3.0-5.0cm, the aperture of the gauze covering the first layer of holes is 2.0-3.0mm, the aperture of the gauze covering the holes in the bottom layer is 0.5-1.0mm, when the number of layers of holes is greater than 2, the aperture of the gauze covering the holes in the middle layer is 1.0-2.0mm, and the distance between the upper edge of the holes in the top layer and the upper port of the incubation tube is 5-6cm.

[0011] A further improvement of the technical solution of the present invention is that the vacuum pump and the water level sensor are controlled by a controller.

[0012] The field earthworm seedling raising method uses the field earthworm seedling raising device, comprising the following steps:

[0013] S1. Connect the filter of the delivery pipe to the drainage tank through the pipeline, and connect the drainage tank to the vacuum pump;

[0014] S2, the earthworm seedlings hatched in the incubator or the earthworm eggs that have been hatched and are about to break out of the shell are placed into the bottom of the incubation tube, the earthworm seedling feed is filled on it, and the upper opening of the incubation tube is sealed with a gauze;

[0015] S3, inserting the delivery tube installed in step S2 into the earthworm breeding bed, and half-inserting the drainage tank into the breeding bed;

[0016] S4. When the water level in the sedimentation tube rises too high, turn on the vacuum pump to suck the water into the drainage tank;

[0017] S5. After 5 days, check whether there are still earthworms in the hatching tube. If there are a large number of earthworms, continue to cultivate them. If there are very few earthworms, take out the seedling delivery device, clean the delivery tube and drainage tank, and carry out the next seedling delivery.

[0018] A further improvement of the technical solution of the present invention is that the earthworm seedling feed includes peat and coconut bran, and the weight ratio of peat to coconut bran is 3:1.

[0019] A further improvement of the technical solution of the present invention is that the water level rise in step S4 can be sensed by a water level sensor in the deposition tube, and then a signal is transmitted to the controller, and the vacuum pump is turned on and off by the controller.

[0020] A further improvement of the technical solution of the present invention is that the insertion depth of the delivery tube into the culture bed is such that the upper edge of the first layer of holes in the hatching tube is flush with the culture bed.

[0021] The further improvement of the technical solution of the present invention lies in that: the diameter of the hatching tube is 13 cm, the height of the hatching tube is 30 cm, the height of the sedimentation tube is 10 cm, and the height of the hatching tube exposed above the breeding bed is 5 - 6 cm.

[0022] Due to the adoption of the above technical solution, the technical progress achieved by the present invention is:

[0023] In this application, earthworm seedlings or earthworm eggs that have completed hatching and are about to break their shells are first placed in the feeding tube for breeding. The earthworm seedlings grow while eating from the bottom to the top of the hatching tube. After 4 or 5 days, the feed in the hatching tube is eaten up, and the earthworm seedlings have grown. They crawl out through the mesh holes on the holes. During this process, they gradually adapt to the environmental conditions such as the temperature and humidity of the breeding bed.

[0024] The hatching tube of this application is evenly provided with holes on its tube body, and a gauze net is covered on the holes, which can increase the air permeability inside the hatching tube. Moreover, the liquid in the breeding bed can also enter the hatching tube through the gauze net, and then filter into the sedimentation tube through the sealing water-permeable net. Since acidic substances will be produced during the earthworm breeding process, if the acidity is too high, it will cause harm to the earthworms. Through such a design, the acidic substances enter the sedimentation tube together with the liquid and will not affect the earthworms. The pore diameters of the gauze nets on the holes are different. The pore diameter of the first layer is the largest, which is convenient for the grown earthworms to crawl out of the holes into the breeding bed. The design of the gauze nets on the holes can prevent pests in the breeding bed from harming the earthworm seedlings, and can also allow the earthworms to gradually adapt to the environment of the breeding bed during the growth process, ensuring the survival rate of the earthworms.

[0025] Earthworms like humidity and dislike dryness, and generally maintain a humidity of 60 - 70%. Therefore, after the earthworm seeding device is inserted into the breeding bed, liquid will enter. The setting of the sedimentation tube in this application can keep the humidity inside the hatching tube, but will not cause waterlogging, and can exclude acidic substances. A filter is arranged in the sedimentation tube and is connected to a drainage tank, which can discharge the excess liquid. Therefore, rainy weather will not affect the growth of the earthworm seedlings. Description of the Drawings

The distance between the upper edge of the top layer of holes 3 and the upper end of the hatching tube 1-1 is 5-6cm.

[0038] Field earthworm farming methods, such as Figure 2 As shown:

[0039] S1, install the hatching tube 1-1 and the sedimentation tube 1-2 of the seedling throwing device, connect the filter to the drainage tank 4 through the pipeline, and connect the drainage tank 4 to the vacuum pump;

[0040] S2, put the earthworm seedlings hatched in the incubation chamber into the bottom layer of the incubation tube 1-1, fill it with earthworm seedling feed, and seal the upper opening of the incubation tube with a gauze;

[0041] S3, inserting the delivery tube 1 installed in step S2 into the earthworm breeding bed 8, and half-inserting the drainage tank 4 into the breeding bed;

[0042] S4. When the water level in the sedimentation tube 1-2 rises too high, turn on the vacuum pump to suck the water into the drainage tank;

[0043] S5. After 4-5 days, check whether there are still earthworms in the hatching tube. If there are a large number of earthworms, continue to cultivate. If the number of earthworms is very small, take out the seedling delivery device, clean the delivery tube 1 and the drainage tank, and carry out the next seedling delivery. The earthworm seedling feed includes peat and coconut bran, and the weight ratio of peat to coconut bran is 3:1.

[0044] Example 4

[0045] Based on Example 3, the diameter of the hatching tube 1-1 is 13 cm, the height is 30 cm, the height of the sedimentation tube 1-2 is 10 cm, the height of the hatching tube 1-1 exposed above the breeding bed 8 is 5-6 cm, the hole 3 is provided with 2 layers, the aperture of the gauze on the first layer of holes is 3 mm, the aperture of the gauze on the lower layer of holes is 1 mm, the aperture of the water-permeable net 6 is 0.1 mm, and the aperture of the gauze used to seal the top of the hatching tube 1-1 is 0.2 mm.

[0046] Farming Example

[0047] The earthworm seedling planting device of Example 4 of the present application was used to conduct experiments to verify the effectiveness of the earthworm seedling planting and breeding method of the present application.

[0048] The experiment has a total of 4 treatments, each of which is a small area. An earthworm breeding bed is set in each small area. The cross-section of the breeding bed is an isosceles trapezoid, with an upper width of 0.55m, a lower width of 0.7m, a height of 0.5m, and a length of 2m. The spacing between small areas is 1m, and the bottom and sides of the breeding bed are isolated with non-woven fabrics. The breeding beds in each small area are laid in the same way, and the humidity, light, and breeding bed conditions are the same. The same number of the same earthworm seedlings are placed in each small area, and the length of the earthworm seedlings is 0.8-1.2cm. Two of the small areas use the seedling throwing device of the present application for earthworm breeding. Each small area has a total of 2 seedling throwing devices, which are spaced at the same distance. The seedling throwing devices are equipped with feed and earthworm seedlings. The other two small areas use the original breeding method (i.e., the earthworm seedlings are directly and evenly spread on the breeding bed). During the process, pay attention to maintaining the humidity of each breeding bed at 60-65%. After 30 days of cultivation, the earthworms in each small area are screened. The experimental results are as follows:

[0049]

[0050] It can be seen from the above experiments that the survival rate of earthworm seedlings is greatly improved when the seedling throwing device of the present application is used for breeding, and the weight of a single earthworm is also increased. Since the earthworm seedlings gradually adapt to the breeding bed environment in the seedling throwing device and grow in the seedling throwing device for 4-5 days (they leave the seedling throwing device when they grow to about 2-2.5 cm), they avoid the invasion of pests on the larvae.

[0051] Since the growth process of earthworms requires the humidity of the breeding bed to be around 60%-70% and the pH to be 6-8, and earthworms will produce acidic substances when growing, causing the pH in the incubation tube to drop, the seedling delivery device of the present application is provided with a sedimentation tube at the lower part of the delivery tube. The water infiltrating through the holes will penetrate into the sedimentation tube through the permeable net, and at the same time, the acidic substances produced during the growth of the earthworm seedlings will be brought into the sedimentation tube, which will not cause harm to the earthworm seedlings.

[0052] The earthworm seedlings grow while eating from bottom to top in the incubation tube. The holes (with nets) on the incubation tube can prevent pests from invading the earthworm seedlings, and can also allow moisture and other substances in the breeding bed to enter the incubation tube. The earthworm seedlings can gradually adapt to the environment of the breeding bed. When the earthworm seedlings finish eating the feed in the incubation tube, they drill out of the delivery device through the mesh holes on the upper holes of the incubation tube and drill into the breeding bed to continue growing. The use of the seedling delivery device of the present application can prevent pests in the air and in the breeding bed from invading the earthworm seedlings, and can also give the earthworm seedlings a certain amount of time to adapt to the breeding bed so that they gradually adapt. Therefore, the survival rate of earthworms is greatly improved, and the individual weight of a single earthworm is increased.
