Herbaceous species diversity in relation to fire severity in Zagros oak forests,Iran

Zagros forests are mainly covered byQuercus brantii L. coppices and oak sprout clumps occupy the forest area like patches. We investigated post-fire herbaceous diversity in the first growing season after fire. For this purpose neighboring burned and unburned areas were selected with the same plant species and ecological conditions. The data were collected from areas subjected to different fire severities. Overall 6 treatments were considered with respect to fire severity and the mi-crosites of inside and outside of oak sprout clumps including： unburned inside and outside of sprout clumps （Ni and No）, inside of sprout clumps that burned with high fire severity （H）, inside of sprout clumps that burned with moderate fire severity （M）, outside of sprout clumps that burned with low fire severity （OH and OM）. Different herbaceous com-position was observed in the unburned inside and outside of oak sprout clumps. The species diversity and richness were increased in treatments burned with low and moderate fire severity. However, in treatment burned with high fire severity （H）, herbaceous cover was reduced, even-ness was increased, and richness and diversity were not significantly changed. We concluded that besides the microsites conditions in forest, fire severity is an inseparable part of the ecological effect of fire on her-baceous composition.

实用是杂志的立足之本

正我是《花舟盆景》园艺版的老读者、老订户,自1999年订阅以来至今已有14个年头,今年还增订了《盆景赏石版》。虽然我对花卉没有更深的研究’抽空翻翻,也感到心旷神怡。如今,我年近古稀,彻底退休休养了,每天除了看报外,更多的时间在研究养花种草,但缺乏有人指教,《花細艺》是我最好的老师,特别吸引我眼球的是养花月历     

再见风铃草

正风铃草是种美丽的草本野花,春夏之交在山野沟壑到处开放,如一串串白色灯笼在草丛摇曳,远远望去若风中精灵,煞是好看。童年时代,我虽爱此花却一直不知它姓甚名谁,四处着人打听,终无结果。幼时居住的小镇到处是野山花,印象最深的两种一是风铃草,另一种至今仍未闻花名。花朵粉色成串,气味发臭,但花色艳丽惹眼,记忆颇深。我的童年开满了风铃草,它是我心中思念的影像。此后小镇修建电厂,山坡被机械开垦,许多野花因工业进程而消失。再后来,我离开家乡,风铃草的淡雅幽香,只存于记忆深处。去年初,我与一位爱鸟的师长谈及此     

冬花的栽培技术

冬花也叫九九花、款冬等．为菊科多年生草本。叶片心脏形。头状花序。花蕾紫色,形似芽苞,开放时黄色,秋末孕蕾,立冬后生长,故称冬花。冬花喜凉爽湿润气候。怕热、怕旱、怕涝,气温超过36℃时。若不及时降低温度和加强管理．则容易塌叶．甚至因过热而枯死。冬花喜肥沃、疏松、湿润的土壤。     

草本花卉穴盘育苗技术刍议

穴盘育苗主要应用于花卉和蔬菜育苗,尤其适用于草花小粒种子的播种育苗。播种时一穴一粒,成苗时一室一株,每株幼苗都拥有独立空间,水分养分互不竞争,出苗整齐,幼苗根系完整,生长发育快速整齐,移植后的成活率接近100%,观赏价值较高。
