Abstract:
The grasses could not only enrich the structure and texture of the landscape in flower meadow,but also effectively resist the invasion of weeds.In order to choose the appropriate species of forbs and sowing ratio for grass-forb mixture community,22 kinds of forbs were chosen to be sown with 2 kinds of grass in 5 gradients setting in accordance with the weight ratio.The growth characteristics of forbs in different mixture communities was compared.The results showed that grasses in grass-forb mixture communities would not affect the species′ number of forbs，but it would cause inhibitions on forbs′ germination rate，survival rate，plant density，height and crown growth，which were positively related to the sowing rate.The sowing rate of forbs and grasses should not exceed 1∶2.When establishing a forb-grass mixture community，the proportion of annual forbs needed to be reduced and the proportion of perennial forbs needed to be increased to enhance continuity and stability.The annual forbs which germination early and grow faster in initial period and the perennial forbs which tolerant shading and pruning during their seeding should be chosen.
