Functional environment of downy brome communities in relation to weed control and revegetation.

摘要: We Imeasured somIie of the imore important biologic and microclimatic parameters functional environmient downy brome (Bromuis tectorn-m L.) cominunities during establishment period seedlings intermediate wheatgrass (Agropyron intermedium (Host) Beauv., -var.
