Description
This paper reports the results of an experiment with smooth bromegrass (Bromus inermis Leyss) under cutting management at Beijing Agricultural University, China from June-October 1989. The main treatments were cutting intervals (l month v. 2 months) and cutting height (10 cm v. 30 cm) with 2 additional treatments (uncut control, and delayed first cut) and 4 replications. Frequent cutting decreased tiller population density, herbage accumulation and underground biomass. Tiller populations were greater under lax than hard cutting, though closer cutting resulted in greater green herbage accumulation. Delaying cutting until flowering was completed resulted in a subsequent depression in herbage yield. Regrowth in the following spring was not significantly affected by the cutting time, cutting height, or cutting frequency. From this and other experiments the recommended cutting regime for smooth bromegrass in northern China is for an initial cut at anthesis, at a cutting height of 10 cm, and subsequent defoliation at this height at 2-month intervals.
