A Comparative Study of Dry Matter Yield and Quality of Pasture Sown Different Species Seed Combination

摘要

This study was conducted to investigate the effect of mixture types which consist of different species on the dry matter(DM) yield, botanical composition and forage quality. The experimental design includes three mixture types: Conventional mixtures(orchardgrass 50% + tall fescue 20% + perennial ryegrass 10% + Kentucky bluegrass 10% + white clover 10%), complex mixtures(orchardgrass 40% + tall fescue 20% + perennial ryegrass 10% + Kentucky bluegrass 10% + redtop 10% + alfalfa 5% + red clover 5%) andsimple mixtures(orchardgrass 80% + red clover 20%). The DM yield was higher in conventional mixtures( 13,070 kg/ha) than in other mixtures(p
