摘要
经两年的刈割对两种牧草生物量和蘖密度影响试验,结果表明,营养期和繁殖期开始不同刈割间羊茅黑麦草生物量和蘖密度差异不显著;不同留茬高度间无芒雀麦地上干物质重和蘖密度差异不显著;羊茅黑麦草差异显著。
The effects of defoliation on biomass and density of two grasseswere conducted in two years.The results were that there are notsignificant difference between vegetative and reproductive growth stagein Fescu Ryegrass,and between 2 and 6 cm cutting teight for abovebiomass and density in Smooth Bromegrass. But,there were difference significant between Various cutting geight in Fescue/Ryegrass.
