Problems solved by technology

[0005] The invention provides a method for making fungus chaff and earthworm feedstuff, which is to mix the fungus chaff and cow dung according to a certain proportion after fermentation, properly adjust the humidity and pH, and put in suitable size earthworm species according to a certain density, and Compared with traditional cow dung earthworm feed, it can significantly increase the production of earthworms by 1 to 3 times, and solve the problems of environmental pollution caused by the backlog of discarded fungus chaff in the edible fungus industry. Consumption, high quality, ecology, and environmental protection transformation provide an effective production method for artificially raising earthworm feed

Embodiment 1

[0022] The preparation method of the fungus chaff is Bailing mushroom or tea tree mushroom chaff: The pre-treatment method of the fungus chaff is: select the fungus sticks without any bacteria pollution, break the bag, peel off the plastic bag, and then pulverize, the particle size is 0.5cm; use cottonseed It is made of skin, wheat bran, and corn flour as the main raw materials, and it is the residue of the compost after one or two mushrooms.

Embodiment 2

[0024] Fermentation method of bacteria bran earthworm feed:

[0025] (1) After the fungus chaff and cow dung are selected and crushed, they are sieved to remove debris and stacked separately;

[0026] (2) Adjust the selected crushed fungus chaff and cow dung to about 60%~65% humidity, respectively build trapezoidal stacks with a width of 2~3m, a height of 1m, and unlimited length, and naturally ferment for 25-28 days;

[0027] (3) Turn the compost for the first time on the 5th to 7th day of natural fermentation, the second time on the 11th to 12th day, the third time on the 15th day, and the fourth time on the 20th day. Fermentation time It is closely related to the local temperature at that time. The raw materials are mixed and preliminarily degraded through fermentation to kill bacteria and diseases. During the fermentation process, the central temperature of the stockpile is maintained at 50~65°C;

[0028] (4) Spray water on the surface of the stockpile when the first turn...

Embodiment 3

[0032] The feeding density of this feed is 25kg of earthworm seeds per ton of dry material, of which the weight of a single earthworm is 0.5 g, and then the earthworm seeds are evenly sprinkled on the surface of the fungus chaff fermentation pile, allowing them to climb in naturally. The feeding condition is 60% humidity , keep the temperature at 20°C, avoid light, keep moisture, prevent ant pests and diseases, keep the environment quiet, and the time for raising earthworms is 35 days before collecting earthworms. The earthworms used were Eisenia chinensis ( Eisenia foetida (Savigny, 1826)) "Daping 2" worm species.

Abstract

The present invention provides germ bran feed for earthworms and a preparation method and an application thereof. The feed is obtained by fermenting the germ bran and cow dung, evenly mixing the germ bran and the cow dung according to a certain proportion, properly adjusting humidity and pH, and putting earthworm seedlings in appropriate sizes according to a certain density. Compared with the traditional cow dung earthworm feed, the feed can significantly improve earthworm yields by 1-3 times, not only solves environmental pollution and other problems in the edible fungus industry caused by waste germ bran backlog, but also increases the earthworm yields and germ bran fertilizer efficiency, so that the germ bran gets high efficiency, low consume, high quality, ecological and environmental protection transformation. An effective feed production method is provided for artificial breeding earthworms.

Description

technical field [0001] The invention belongs to the technical field of edible fungus development, and relates to the recycling and reuse of discarded fungus chaff at the end of the edible fungus industrial chain, and more specifically relates to a fungus chaff earthworm feed and a preparation method and application thereof. Background technique [0002] As a large agricultural country, China is producing more and more edible fungi. According to statistics, in 2014, the total output of edible fungi in the country was about 28 million tons, and about 91 million tons of fungus chaff was produced, and it is still growing at a rate of 10%. With the increase in the output of edible fungi, the output of discarded substrates after the cultivation of edible fungi is also increasing. The discarded substrate after the cultivation of edible fungi is called edible fungus chaff, which is rich in residual mycelium, protein, amino acids and other nutrients, but the traditional method of dis...
