摘要：

The effect of stocking rate and moisture content on the growth and maturation of Eisenia andrei (Bouche, 1972) in pig manure was studied in laboratory trials at 20 degrees C. Six moisture contents (65, 70, 75, 80, 85 or 90%) and five stocking rates (1, 2, 4, 8 or 16 worms, each per the same volume of substrate) were tested. Growth and maturation of earthworms were monitored over 44 days. The 85% moisture content was found to be most favourable for earthworm growth. The 80 and 90% moisture contents were found to be adequate. Eight earthworms per 43.61 g (dry wt) was found to be the most favourable inoculation density. (C) 1997 Elsevier Science Ltd.
