摘  要：
为探讨林地树叶对牧草的影响,研究了阿丁枫 、钟花樱桃 、枫香和红花油茶鲜叶与枯落叶的浸提液对宽叶雀稗种子萌发及4种枯落叶覆盖对幼苗生长的影响,并研究了浇灌钟花樱桃鲜叶 、阿丁枫枯落叶浸提液对宽叶雀稗幼苗的影响.结果表明:1)4种树叶对宽叶雀稗的发芽率和发芽指数有不同程度的降低作用,并抑制幼根生长,抑制程度随浓度增大而增强,低浓度时促进幼芽生长;2)枯落叶覆盖抑制株高和分蘖;3)浇灌钟花樱桃鲜叶和阿丁枫枯落叶浸提液抑制分蘖 、减少地上生物量.研究表明,4种树叶主要抑制宽叶雀稗幼根生长 、幼苗分蘖 、株高和减少生物量,其中钟花樱桃鲜叶和阿丁枫枯落叶的抑制程度较强.

摘  要：
To study the effects of forest land plant leaves extract on growth of grass,the seeds of broadleaf paspalum were treated with the extract of fresh leaves and withered leaves from Altingia chinensis,bell flower cherry,maple and red flower camellia to investigate the seed germination and the effects of 4 kinds withered leaves cover and irrigation with withered leaves extracts from bell flower cherry and A. chinensis on seedling growth was also analyzed.The results showed that: 1) Four kinds of leaves could reduce the germination rate and germination index of paspalum,and inhibit the growth of young roots; 2) The withered leaf cover inhibited plant height and tiller; 3) Treated with the extracts from fresh leaves of bell flower cherry and withered leaves of maple could inhibit tillers and reduce aboveground biomass.Studies had shown that four kinds of leaves mainly inhibited the growth of young roots,tillering of seedlings,plant height and biomass of broad leaved paspalum,among which,the degree of inhibition of fresh leaves of bell flower cherry and withered leaves of A. chinensis was much stronger.
