Problems solved by technology

Because earthworms have the characteristics of different offspring, adult earthworms need to be separated manually during the breeding process. The labor cost is high, the separation speed is slow, and it is easy to cause individual damage and lose economic benefits.
At the same time, there are also the following problems: adult earthworms have limited moving positions in the breeding box, few hybrids, and are prone to inbreeding, causing population degradation and reducing reproductive efficiency; earthworms have limited activity areas in the breeding box, and are easy to migrate based on the characteristics of different offspring. Escape, causing economic loss; limited activity area, mixed with large and small earthworms, easily lead to autolytic loss
The above problems restrict the development of the earthworm farming industry, resulting in the insignificant economic benefits of earthworm farming, which cannot be promoted; the use of earthworm farming to treat organic solid waste cannot form scale benefits to stimulate industrial development
[0005] The traditional box-type culture of earthworms is often based on granular or powdery culture substrates; in order to achieve intensive culture, these scattered culture substrates need box-type or other forms of containers, or stacked into culture beds to cultivate earthworms, so that caused the above problem

Embodiment 1

[0051] The culture medium for cultivating earthworms of the present embodiment is prepared by a method comprising the following steps:

[0052] 1) After mixing 100 parts by weight of the base material with 0.5 parts by weight of the EM bacterial liquid, adjust the humidity to 85% to obtain a mixture; the base material is composed of the following components in mass percentage: 60% of pig manure, kudzu root 10% of slag, 10% of wheat straw, 10% of aquaculture water silt; the straw is crushed and mixed with the formula amount of pig manure, kudzu root slag, and aquaculture water silt to obtain the base material;

[0053] 2) Put the mixture obtained in step 1) into a solid fermentation tank for closed anaerobic fermentation for 24 hours, intermittently rotate and stir during the fermentation process, gradually increase the temperature of the material to 65°C, ventilate and cool to 30°C, and then add 0.5 parts by weight of EM bacterial liquid, continue the airtight anaerobic fermen...

Embodiment 2

[0057] The device of the three-dimensional culture earthworm of present embodiment, as figure 1 , 2 As shown, a support frame 1 is included, and four layers of horizontal grid plates 2 for arranging and placing culture medium 3 are arranged at even intervals on the support frame 1. From top to bottom, the first grid plate 2-1, The second grid plate 2-2, the third grid plate 2-3 and the fourth grid plate 2-4, the distance between adjacent grid plates is 1.0m, and the distance between the fourth grid plate 2-4 and the ground The distance is 0.4m.

[0058] The bottom of each layer of grid plate 2 is equipped with a receiving device for preventing the leakage of the medium 3 material and the escape of cultured earthworms. The receiving device is a plastic film 4, and the plastic film 4 extends along the length of the grid plate 2. Both sides are suspended on the support frame 1.

[0059] Such as image 3 As shown, the plastic film 4 is arranged under the grid plate 2 each time...

Embodiment 3

[0062] The method for three-dimensional cultivation of earthworms of the present embodiment adopts the device for three-dimensional cultivation of earthworms described in Embodiment 2, comprising the following steps:

[0063] a) 4 columnar culture mediums obtained in Example 1 are arranged in parallel and next to each other on the grid plate (such as figure 2 , 3 As shown), to form a culture row, arrange 5 culture rows in parallel and next to each other, and form a layer of culture layer on each layer of grid plate;

[0064] The top view of each culture layer is as follows Figure 4 As shown, part of the adjacent culture medium 3 is in close contact, and part of it is not in contact so as to form a gas channel 8 that runs through the culture layer; the tight contact part between adjacent culture media 3 is convenient for earthworms to move and migrate between the various culture media, so Said gas passes through 8 to make the culture layer gas circulate;

[0065] B) put ki...

Abstract

The invention relates to a culture medium for breeding earthworms and a stereoscopic earthworm breeding method and device and belongs to the technical field of earthworm breeding. The culture medium is prepared through the following method that firstly, a base material and EM bacterium liquid are mixed, humidity is adjusted to 80%-90% to obtain a mixed material, and the base material is mainly composed of livestock feces, coarse fiber materials and sludge; secondly, the mixed material is subjected to closed anaerobic fermentation for 22-26 h, and after temperature is lowered to 28-32 DEG C, the EM bacterium liquid is added to continue the closed anaerobic fermentation for 22-26 h, and a fermented material is obtained; and thirdly, net bags are filled with the fermented material, and after compacting, the culture medium is obtained after piling and thorough decomposing are performed for 1-3 days. The culture medium achieves that pollution is treated through cultivation and achieves effective recycling of organic solid waste, nutrient substances in the base material are reserved to the maximum extent, and the culture medium is suitable for growing and breeding of the earthworms; and a three-dimensional stereoscopic space is provided for activity and breeding of the earthworms, adult earthworms are not needed to be separated manually, and intensified stereoscopic breeding of the earthworms in a greenhouse or in an indoor environment can be achieved easily.

Description

technical field [0001] The invention belongs to the technical field of earthworm cultivation, and in particular relates to a culture medium for cultivating earthworms, and also relates to a method and device for three-dimensional cultivation of earthworms using the culture medium. Background technique [0002] At present, organic solid waste pollution is relatively serious, such as urban and rural industrial organic waste, food production waste, paper mill waste, meal waste, straw, waste mushroom sticks, waste fruits and vegetables, slaughter waste, sludge, Farming manure, etc. have complex and diverse sources and types of substances, making it difficult to effectively deal with them. When there is a problem in the treatment of organic solid waste, it will cause serious pollution to the surrounding environment, such as water pollution, mosquito breeding, air pollution and other environmental damage. At the same time, the loss of nutrient-rich substances in organic waste will...
