Embodiment 1

[0064] Such as Figure 1-4 and Figure 9-12 As shown, a rearing device for Eisenia chinensis, the rearing device includes a top cover 1, a connecting sleeve 2 and a feeding tube 3 from top to bottom, and the connecting sleeve 2 and the feeding tube 3 are both cylindrical tubes structure;

[0065] The top cover 1 is provided with a ventilation pipe 11 , a reserved pipe 12 and a sampling hole 13 through the cover body:

[0066] Wherein, the diameter of vent pipe 11 is 2mm, is used for balancing the internal and external air pressure of raising device;

[0067] The diameter of the reserved pipe 12 is 5mm, which is used to install the thermometer;

[0068] The aperture of sampling hole 13 is 2cm, is used for detecting after collecting the gas in raising device, is equipped with sealing plug 14 on the sampling hole 13;

[0069] The top cover 1 is installed on the top of the connecting sleeve 2, and the bottom end of the connecting sleeve 2 is movably socketed with the feeding t...

Embodiment 2

[0078] Such as Figure 5-12 As shown, the raising device of Eisenia chinensis in embodiment 2 differs from the raising device in embodiment 1 in that: 1. the bottom sealing part of the raising tube 3 adopts gauze, and the gauze is fixed on the gauze by clamp 32. The bottom end of the feeding tube 3; ② the diameter of the feeding tube 3 is 10cm, and the length is 20cm.

[0079] The making method of described sealing member 31 (gauze) is: first, cut out the circular mesh cloth (150 orders) that diameter is 14cm, the square gauze that side length is 25cm is standby. Then, successively superimpose and buckle the bottom end of the raising tube 3 with circular mesh cloth and square gauze, and adopt clamp 32 to be fixedly connected with sealing part 31 (gauze net) and raising tube 3, with the soil in the load-bearing tube and prevent Earthworms escape.

experiment example 1

[0081] In order to verify the feasibility and effectiveness of the feeding device and raising method of the present invention for raising Eisenia chinensis, set up Experimental Example 1, evaluate the feeding situation of Eisenia chinensis by the survival rate and relative growth rate of Eisenia chinensis , thereby illustrating the beneficial effects of the feeding device and the feeding method of the present invention.

[0082] Experimental Example 1 sets up 5 experimental groups, and the experimental conditions of each experimental group are as follows:

[0083] a. The crop stalks used in the feeding substrate of each experimental group are corn stalks, and the super sweet fruit corn variety Huazhen grown in Datian, Guangdong is used;

[0084] b. The experimental group set 5 corn stalk addition gradients, that is, the addition amount of corn stalk in the feeding substrate of each experimental group relative to the soil weight was: 0%, 2.5%, 5%, 7.5% and 10% respectively;

Abstract

The invention relates to the technical field of earthworm culture, and discloses a feeding apparatus of eisenia foetida. The feeding apparatus comprises a top cover, a connecting sleeve cylinder and afeeding cylinder, wherein the top cover is provided with a ventilation pipe, a reserved pipe and a sampling hole, the ventilation pipe is used to balance the air pressure inside and outside the apparatus, the reserved pipe is used to install an air temperature meter, and the sampling hole is used to collect a gas, the top end of the connecting sleeve cylinder is equipped with the top cover, the bottom end of the connecting sleeve cylinder is movably connected with the feeding cylinder in a sleeve manner, the inside of the connecting sleeve cylinder is provided with an anti-escape net, and thebottom end of the feeding pipe is provided with a sealing part. The invention also provides a method for feeding eisenia foetida using the above apparatus, the method is simple to operate, and the earthworm survival rate, relative growth rate and reproduction rate are high. The feeding apparatus of the invention has reasonable structural design, small size, convenient use, and various functions,and is suitable for the experimental study of the affection of the interaction between straw returning to the field and eisenia foetida on soil ecosystem such as the affection on greenhouse gas emissions by combining with the feeding method.

Description

technical field [0001] The invention relates to the technical field of earthworm feeding, and more specifically, to a feeding device, a feeding method and an application of Eisenia chinensis. Background technique [0002] Earthworms belong to the oligochaetes of the phylum Annelida, and they have functions or functions such as medicinal, edible, feeding, environmental purification, and soil improvement. Earthworms promote the decomposition of organic matter through activities such as feeding, digestion, excretion (earthworm droppings), secretion (mucus) and burrowing, thereby promoting the cycle of soil nutrients and improving soil structure and physical and chemical properties, improving soil ventilation, drainage and deep water holding ability, plays an important role in the decomposition of soil organic matter and the cycle of soil carbon and nitrogen, and is called an "ecosystem engineer". [0003] In addition, since earthworms are the main soil organisms that eat and d...
