Abstract : this paper reports the studies on the shapes , properties and microstructures of pennisetum flaccidum , cynanchum stauntonii , easily confused with those of rhizoma imperatae comparision was made for the identification of the confusing drugs 文摘:对白茅根的混淆品白草、柳叶白前根茎进行了药材性状和显微组织构造研究，并与正品白茅根作了对照，供鉴别参考

The malignant weeds in lawn were alternanthera philoxeroides , digitaria sanguinalli , cynodon dactylon , trifolium pretense , hydroctyle sibthorpiodes , cyperus rotundus , eleusine indica , imperata cylindrical , kyllinga brevifolia and oxalis corniculata 其中，空心莲子草、马唐、狗牙根、三叶草、天胡荽、香附子、牛筋草、白茅、水娱蚣、酢浆草等10种杂草为草坪上的恶性杂草，对草坪危害最大。

While part of this land is later used for highly productive tree crop agriculture ( oil palm , rubber , cocoa ) , about 200 , 000 ha end up every year as anthropic savanna , dominated by the noxious grass imperata cylindrica ( alang alang ) 其中部分土壤后来开发为生产力较高的经济树种农用地（油棕榈、橡胶、可可） ，而每年大约20万公顷则变成受人为活动影响的热带稀树草原，主要由毒草白茅（又名印度白茅）组成。

The main results indicated that : significant differences exist in diurnal average transpiration rate and the range of diurnal transpiration rate ; the transpiration rate of sawtooth oak , amorpha , lalang grass varied with a regular double apex rhythm , but that of the rest varied with a regular single apex rhythm , stomatal conductance play a maximal important role in transpiration rate , temperature ( air temperature , the earth ' s surface temperature ) also influence the transpiration rate ; transpiration rate has prominent negative correlation with the relative air humidity , the biggest coefficient is 0 . 866 笔者对日照沿海防护林几种主要木本植物和草本植物的蒸腾速率和环境因子的关系进行了研究，结果表明： 8种植物日平均蒸腾速率和蒸腾速率日变幅各异；麻栎、紫穗槐和白茅的蒸腾速率日变换呈现出双峰式的变化规律，其它5种植物蒸腾速率表现为单峰式的变化规律；气孔导度影响着植物的蒸腾速率，温度（气温、地面温度）是影响植物蒸腾速率的主要因子；空气相对湿度和蒸腾速率表现为显著或极显著负相关，相关系数高达0 . 866 。
