摘要

An experiment was conducted at Wongan Hills Western Australia (WA) in 2016 and 2017, to investigate the biology of ten weed species. The trial investigated recruitment, germination time, survival over the cropping season, seed production and time of shedding. This paper reports the results of annual ryegrass (Lolium rigidum Gaudin), great brome grass (Bromus diandrus Roth), barley grass (Hordeum leporinum Link), doublegee (Rumex hypogaeus T.M.Schust. & Reveal, formerly Etnex australis Steinh) and sowthistle (Sonchus oleraceus L.). Great brome grass seedling recruitment was higher than annual ryegrass recruitment in 2017, even though annual ryegrass had much higher seed set in 2016. Further, brome grass had the greatest impact on crop yield in 2017.Brome grass, barley grass, doublegee and sowthistle all shed their seed earlier than annual ryegrass. Harvesting as early as possible or swathing would be necessary to capture seeds from these species for harvest weed seed destruction.
