摘要
Abstract
Pot experiment with weeping lovegrass was conducted laboratory in the Department of Rangeland, Wildlife and Fish
eries Management, Texas Tech University in 1996. The plants grown in green house were used to study the effect of
different clipping intensities on tillering, and those growu in laboratory were used to study the interaction between dif
ferent R/FR(red/farred)ratio of the light reaching to the lower strata of the canopy and different clipping intensities
on tillering. The results show that increasing clipping intensity decreased the net gain tillers, bt R/FR ratio had no sig
nificant effect on tillering, except no clipping treatment. The compensatory growth effect of tillering did not existed at
all clipping intensities, but the elongation speed of young leaves quickened with clipping intensities. It is suggested that
suitable utilization, intensified utilization and no utilization were all not beneficial to the growth and development of
weeping lovegrass.
