通过连续几年的单一除草剂使用，烟田杂草的优势种群发生了相应变化，原来以看麦娘、马唐、稗草等单子叶杂草为主的群落结构演变成了现在以稗草、马唐及胜红蓟、两栖蓼、茴茴蒜为主的单、双子叶杂草混生结构，说明烟田施用除草剂会引起杂草群落结构变化，因此，在生产上则应注意除草剂的轮换使用。

Twenty three troublesome weeds and five crops were tested to study specificity of helminthosporin. The result showed that 18 out of the 28 species were susceptible to the toxin. Chenopodium serotinum is the most susceptive, and D. sanguinalis, Polygonum aviculare, Beckmannia syzigachna, Chenopodium album and Alopecurus japonicus took second place.

该毒素在150μg/mL浓度下，对马唐胚根生长抑制率达44.59%；当毒素浓度达到200μg/mL时，叶绿素含量下降18.41%；在500μg/mL浓度下，毒素对供试的23种杂草产生的毒害程度不同，其中小藜对毒素最为敏感，其次为马唐、萹蓄、菵草、藜和日本看麦娘等恶性杂草。

This weed population had a wider niche breadth, the second widest among 12 major weed populations in weed community, and had bigger niche overlap with Stellaria alsine, Alopecurus acquallis, Malachium aquaticum, Poa annua, Polygonum persicaria and Lapsana apogonoides. In rape, wheat or fallow, B.

在杂草群落中，草的生态位宽度居第2位，说明其有潜在的较强的适应环境的能力；草与雀舌草、看麦娘、牛繁缕、早熟禾、春蓼和稻搓菜等杂草种群的生态位重叠较大，与它们的生态要求比较接近。

The study shows that weed density in paddy fields significantly decreases with more than 94% grass-controlling effect under SF compared with CK. Before rice booting stage, weeds compose mainly of Alopecurus pratensis, Echinochhloa crausgalli, Cynodon dactylon, Alternanthera philoxeroides, Mouochoria vaginalis, Murdannia triquetra and Eclipta prostrata in SF. During heading to ripe stage, weeds are mainly A. philoxeroides, E. crausgalli, C.

结果表明：规模稻鸭生态种养杂草密度显著降低，与水稻单一种植比较防效为94%；水稻分蘖到孕穗期稻田杂草主要由看麦娘、稗草、狗牙根、水花生、鸭舌草、水竹叶和鳢肠组成，抽穗期到成熟期主要由水花生、稗草、狗牙根和水竹叶组成。
