摘要：The earthworm production in the first two years was affected by the feeding density. In the third year, the earthworm population reached equilibrium, the reproduction of the low-density population accelerated, the reproduction of the high-density population slowed down, and the density difference decreased. The annual cumulative earthworm production reached 250 kg/mu. The harvesting was carried out three times, 70 kg in April, 50% from May to June, i.e., 150 kg, and 80 kg in August. The effect of earthworm culture in the Cauliflower field is better than that in the corn field, reaching 300 kg/mu per year in the Cauliflower field and 200 kg/mu per year in the corn field. The experiment found that the effect of pig manure was better than cow manure, and the effect of fresh pig manure on breeding earthworms was not obvious, but the amount of earthworms increased significantly after one month. The breeding effect of 2000 kg pig manure/mu was very obvious, and the weight of earthworms reached 300 - 400 kg.
