摘要

The growth of juvenile Aporrectodea tuberculata and Lumbricus terrestris under different soil temperatures (10 and 18deg C) and moisture (20, 25 and 30% (w/w) soil moisture content) was determined in a laboratory experiment. The instantaneous growth rates (IGR) of A. tuberculata were between 10.8 X10-3 d-1 and 18.7 X10-3 d-1 and the IGR was lowest when A. tuberculata was placed in soil at 10deg C and 30% (w/w) soil moisture content. The growth of L. terrestris was lower than that of A. tuberculata, and the IGR of L. terrestris ranged from 7.1 X 10-3 d-1 to 13.9 X10-3 d-1 under laboratory conditions. L. terrestris growth was greatest in soil maintained at 10deg C and 20% (w/w) soil moisture content. The growth of juveniles of A. tuberculata and L. terrestris was also examined in the field in large cores containing soil from long-term manure-amended and inorganic fertilizer-treated plots during the spring and autumn of 1995 and 1996. The IGR of A. tuberculata in the field [Ohio, USA] ranged from 7.5 X10-3 d-1 to 14.6 X10-3 d-1 when soil temperatures were between 10 and 18deg C, and was comparable to the IGR of A. tuberculata under similar environmental conditions in the laboratory. The growth of L. terrestris in the field was much lower than L. terrestris growth in the laboratory under similar environmental conditions, and the IGR of L. terrestris in the field ranged from -1.0 X10-3 d-1 to 5.3 X10-3 d-1 when soil temperatures were between 10 and 18deg C. The growth of A. tuberculata and L. terrestris was not significantly different for individuals placed in cores containing soil from either manure-amended or inorganic fertilizer-treated plots. While there appeared to be adequate soil organic substrates for A. tuberculata growth in the field. L. terrestris growth was probably limited by the absence of sufficient surface organic residues. The IGR equation can be used to predict the nonlinear growth of earthworms under laboratory and field conditions.
