Based on morphological characteristics and sequence alignment analysis of rDNA ITS region, 16 strains isolated from diseased plants of Setaria viridis from Beijing, Hebei and Henan, two strains isolated from diseased plants of Chloris virgata and Eleusine indica from Henan, and one strain isolated from diseased plant of Avena fatua from Qinghai, were identified as Bipolaris setariae.

经形态学鉴定和rDNA ITS序列分析，16株分离自北京、河北、河南发病狗尾草的菌株、2株分别分离自河南发病虎尾草、牛筋草的菌株和1株分离自青海发病野燕麦的菌株被鉴定为狗尾草平脐蠕孢Bipolaris setariae。

Barnyard grass, Echinochloa crus-galli, is one of the notorious weeds worldwide. To explore the potential of Alternaria augustiovoidea strain AAEC05-3 as mycoherbicide to control barnyard grass, the effect of inoculum potential and spray volume on the pathogenicity of strain AAEC05-3 to barnyard grass and host specificity of strain were studied using pot experiment.

为了确定稗草生防菌狭卵链格孢Alternaria augustiovoidea菌株AAEC05-3防除稗草的潜力，研究了其孢子接种浓度和喷液量对该菌株致病力的影响及菌株的寄主专化性。

From Leontopodium nanum (collected from Zhang County, Gansu Province), 12 compounds were isolated, of which 9 compounds have been identified. Among them, a derivative of coumarin is new.

从采自甘肃漳县的矮火绒草全草的甲醇提取物中，采用同样方法共分离纯化得到12个化合物，鉴定了9个化合物的结构，其中有1个新化合物，命名为6，7-并二氧六环[2-（1-甲酯基-1-甲基）-甲烯基]-香豆素（1）。

The results of the 60 days experiment showed that both submersed macrophytes(Hydrilla verticillata,Potamogeton malaianus and Vallisneria natans) and floating-leaved macrophytes(Nymphoides indica and Trapa quadrispinosa)had very high removal rates for TN,TP,NO_3~——N and PO_4~——P,and the values exceeded 60%,but Potamogeton malaianus and Vallisneria natans were most effective at removing nutr...

结果表明，沉水植物马来眼子菜、苦草、轮叶黑藻和浮叶植物荇菜、菱等5种水生植物对水体的总氮、总磷、硝态氮和正磷酸盐都有较好的去除效果，去除率在60%以上，且以马来眼子菜和苦草的效果最好，去除率在80%以上。

The Pn of Phragmites communis is higher than that of Phalaris arundinacea L, meanwhile Phragmites communis has the higher diurnal photosynthetic capacity, which shows that the Phragmites communis could grow more rapidly, and have higher biomass, so the Phragmites communis could be one of the priority implemental plant.

芦苇的Pn比虉草的Pn高，同时芦苇较虉草有更大的日光合量，说明芦苇相比较长势更快，生物量更高，当年栽植当年见效，在湿地生态系统人工修复中可作为优选工具植物之一。
