Embodiment 1

[0022] A preparation method of high-quality vermicompost, comprising the following steps:

[0023] (1) Take fresh cow dung, crushed kitchen waste, wood bran, corn stalks, bagasse and edible fungus waste residues for crushing, adjust the humidity to 50-70%, and ferment for 15 days in a natural pile; Keep the central temperature of the material pile at 66-72°C; after the fermentation is complete, spray water to make the humidity of the material 60-70%. Among them, the water content of fresh cow dung is 60-70%, the water content of kitchen waste is 55-65%, and the particle size of food waste is 3-4mm. Cow dung: kitchen waste: wood bran: corn straw: bagasse: edible The mass ratio of the bacteria waste residue is 3:1:2:1:3:2; the mixture is obtained by mixing, and the mixture is the earthworm feed; the inoculation method is one-time inoculation.

[0024] (2) Use earthworm feed as the breeding substrate for earthworms, use a 10m x 3m block as a digestion bed, the stacking height is...

Embodiment 2

[0027] Take the 1m × wide 0.3m plot as the test area, the stacking height is 0.3-0.4m, put 2000 worm species in each test area, and use the feedstuff of Example 1 and the commercially available earthworm feedstuff as contrast, parallel Three repetitions, feeding for 45 days at a temperature of 22-26°C, a humidity of 60-70%, and a pH of 6.5-7.5. Collect earthworms and weigh them. When weighing, first take out the earthworms and place them in a beaker, then add distilled water for quick cleaning , dry the water on the surface of earthworms with filter paper, and finally weigh them with an electronic balance and record the results, and calculate the average weight gain of a single earthworm (average weight gain of earthworms = (total weight of earthworms after a period of time - initial weight of earthworms) / number of earthworms ). And collect the vermicompost of each test area, the results are shown in Table 1.

[0028] Table 1 The weight of earthworms cultured in different s...

Abstract

The invention discloses an earthworm raising material as well as a preparation method and application thereof, and relates to the technical field of earthworm ecological cultivation. The raising material disclosed by the invention is prepared from raw materials of fresh cow dung, kitchen waste, wood bran, corn straw, bagasse and edible mushroom waste residues. The preparation method of the earthworm raising material comprises the following steps of crushing the raw materials, performing natural pile fermentation under the humidity of 50-70% for 15 days, and after the pile fermentation is completed, sprinkling clean water to obtain the earthworm raising material. A method for feeding earthworms with the raising material comprises the following steps of using the earthworm raising material as an earthworm breeding substrate, inoculating the earthworms with the earthworm raising material in the mass ratio of the earthworms to the earthworm raising material being 1 to 30, and performing breeding; and after the earthworm raising material is completely digested by the earthworms, collecting the earthworms and earthworm cast. According to the earthworm raising material disclosed by the invention, on the base of guaranteeing the earthworm culturing quality, high-quality earthworm cast rich in high humic acid is obtained, the waste resource reusing level is further increased, besides, the economic value of the earthworms is also increased, and unification of environmental benefits and economic benefits is achieved.

Description

technical field [0001] The invention relates to the technical field of earthworm ecological breeding, in particular to an earthworm feed, a preparation method thereof, and a high-quality vermicompost obtained by raising the feed. Background technique [0002] With the intensive development of agricultural production in my country, especially the large-scale development of cattle farms, the problem of environmental pollution caused by cow dung has become increasingly prominent, and there is an urgent demand for resource utilization technologies for agricultural waste such as cow dung. Kitchen waste is a kind of organic waste, including leftovers, leftovers, vegetable leaves, fruit peels, eggshells, tea dregs, bones, shells, etc. It is the source of raw materials and finished products or residues needed in family life and diet. With the improvement of people's living standards, a large amount of food waste has been generated. At present, the treatment method of food waste is t...
