将花卉与禾草混播不仅能够丰富群落的景观结构和质感,还能有效地抑制杂草入侵。为研究禾草-花卉混播群落中适用的花卉种类和适合的混播比例,选择22种花卉与2种禾草为试材,按种子质量比设置5个不同梯度的禾草-花卉混播组合,比较不同组合建植群落中花卉的生长特性。结果表明:禾草-花卉混播群落中禾草不影响花卉植物的种类数量,但会抑制花卉植物的萌发率、成活率、植株密度、株高和冠幅的增长,抑制的强度与混播比例呈正相关。花卉与禾草的混播比例应不超过1∶2。为了群落景观的延续性和稳定性,禾草-花卉混播组合中应减少一年生花卉比例,增加多年生花卉比例;一年生花卉应选择萌发早,初期生长速率相对快的种类,多年生花卉应选择幼苗耐阴耐修剪的种类。
Mixing flowers and grasses can not only enrich the landscape structure and texture of the community, but also effectively restrain the weeds from invading. In order to study the suitable flower species and the suitable proportion of mixed sowing in the grass - flower mixed sowing community, 22 kinds of flowers and 2 kinds of grass were selected as tested materials, and 5 different grasses - flower mixed sowing combinations were set according to the seed mass ratio Growth characteristics of flowers in different combinations of planting communities. The results showed that the grasses did not affect the species number of the flowers and plants in the grass-flower mixed-sowing communities, but inhibited the growth of the flower plants in terms of germination rate, survival rate, plant density, plant height and crown width. Related. Mixing ratio of flowers and grasses should not exceed 1: 2. In order to maintain the continuity and stability of community landscape, the proportion of perennial flowers should be reduced and the proportion of perennial flowers should be reduced in the combination of grass and flowers. The perennial flowers should have the characteristics of early germination and relatively early growth rate, Scratch resistant species.
