Effects of different plant density on seed yield of Mongolia wheatgrass

摘要：

Plant population density is the most important factor affecting seed production, especially for perennial crop (Askarian et al., 1995 ; Chen Shu‐ming et al., 2005 ).The optimal plant density can not only enhance the seed yield and quality, but also be beneficial to weed control, hence decreasing the cost of field management and improving the production effectiveness.The plant population density is mainly decided by row spacing and sowing rate.A gropyron mongolicum Keng.cv.Mengnong No.1 is a new variety with high drought and cold resistance, which is a favorable material to establish artificial pasture in arid and semi‐arid areas in northern China.The purpose of the study is to determine the suitable row spacing and sowing rate for the pasture establishment.
