本试验对纤毛鹅观草、苇状羊茅、鸭茅三个草种组成的4个混播组合进行产草量、越夏率的互比,并对混播与单播的产草量作了比较。结果以纤毛鹅观草+苇状羊茅+鸭茅组合最佳,4个混播组合产草量均比供试3个草种之任何一种单播高. In this experiment, the four mixed-sowing combinations consisting of three grass species, Cynanchum grassland, Tall fescue and Dactylis glomerata, were compared for the ratio of grass yield and over-summer, and the yield of mixed grass and unicast was compared . Results The results showed that the combination of Cunninghamia lanceolata + Tall Fescue + Dactylis maximus was the best, and the yield of the four mixed-sowing combinations was higher than that of any of the three grass species tested.
