Effect of combinations of sowing time, seed rate and herbicides on ryegrass management in wheat

This field trial was undertaken at Roseworthy in South Australia, a medium rainfall environment, to investigate factorial combinations of sowing time, seed rate and herbicides on the management of annual ryegrass in wheat.

本田间试验于澳大利亚南澳州罗斯沃西（Roseworthy）开展，该区域属中等降雨环境，旨在探究播种期、播种量与除草剂的析因组合对小麦田中一年生黑麦草的防控效果。
