(a) Feeding density and temperature. Feeding density 0.35kg per m2 (implantation rate 70% - 80%). When it grows to 4-5 years old, the temperature of the rearing room can be controlled by the temperature of the breeding house (the breeding room can be in accordance with the three-dimensional constant temperature method Construction) General O °C is a hibernation period, no heating; 0-25 °C is not suitable for growth phase; 25- 32 ~ C is the most suitable growth phase; 40 °C above the death phase. (b) Feeding density and thickness of feeding soil. The thickness of 2-4-year-old locust (land yuan) is generally 2-3cm. With the growth of earthworms (earth yuan), the stocking density is increasing, and the thickness of the cultivating soil should be gradually increased. The relationship between stocking density and humidity. If the density is too small, the amount of activity of the earth locust (earth yuan) is small, which can easily lead to soil compaction and uneven wet and dry conditions affecting its growth. The water needed for the growth of earth locusts (earth yuan) is absorbed by its own surface. , severely water shortage will die. Achieving a certain stocking density, through the amount of activity of earthworms (terrestrial earthworms), we can always grasp the humidity of the cultivating soil, and generally can complete a generation cycle in 6 months. Breeding density can not be too high, generally hit the bottom of the pool by hand, the surface of the pool will appear like a wave-like peristaltic maximum density. (c) Feeding density and feeding management. During feeding, it is appropriate to grasp the rearing density, and it is beneficial to grasp the amount of feeding, and there will be no shortage of food, and it will be conducive to constant humidity, so that the skin of the earthworm is normal. (4) Feeding density and economic benefits. High-density farming can save energy, expenses, and increase production in the same investment.
