Earthworm raising material as well as preparation method and application thereof

[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 0.

[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.
