蓼

Weeding-proof experiment of 8 fine ruderal in pot culture with 5 soil treatment pesticide formula were studied,The results show:the bes effect of weeding-proof to polggonum is Kuocaoqing and Guangmieling,The weeding-proof rate is 84.2

选用 5种土壤处理剂，对 8种优势杂草进行盆栽防除试验研究，结果表明：防除酸模顺蓼的特效药剂是阔草清和广灭灵防效为 84 2

In the self-portrait of Lu Xiao seemed to imply such subtext: I am thinking something, please leave me alone.

在蓼萧的自画像里似乎隐含着这样一句潜台词：我在想心事，离我远点。

The ovary of Phyllostachys praecox had one anatropous ovule. The crassinucellate ovule had diploid integuments. The monosporic embryo sac had one tetrad which turned on line and many antipodal cells. The synergid had the obvious filiform appratus.

3雷竹子房1室，内具1个倒生胚珠；双珠被，厚珠心；蓼型胚囊，单孢发育，线形大孢子四分体，具多个反足细胞，助细胞具明显丝状器。

The result shows that:（1） As the tourist disturbance decrease, the important value of Carex lanceolata and Polygonum Viviparum increased, while the important value of Taraxacum mongolicum decrease.

结果表明：（1）随旅游干扰强度降低，马仑亚高山草甸的优势种披针苔草和珠芽蓼的重要值逐渐增大，而广生态幅植物蒲公英重要值却呈降低趋势。

Tartary buckwheat's scientific name is Tartarian Buckwheat, which belongs to Polygonaceae crop. It is a plant having medical and food function.

摘 要：苦荞麦俗称苦荞，学名鞑靼荞麦，属双子叶蓼科荞麦属植物，具有药食两用功能。

When single herbicide was used in the field for two years, the dominant species took place corresponding alternation. The community structure that originally mostly consisted of dicotyledonous weeds , such as Alopecurus aequalis sobol., etc.

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。

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 results were as follows:(1) Seeds of 80 species or subspecies could be classified into two groups. Group Ⅰ included the seeds of Gramineae, Cyperaceae, Polygonaceae and Amaranthaceae, and Group Ⅱ included the seeds of Compositae, Euphorbiaceae, Brassicaceae and Umbelliferae.(2) Only FTIRs of the seeds of Brassicaceae were clustered together in the dendrogram,while those of the other families all appeared farraginous.(3) Among FTIRs of the 11 groups of the congeneric species,8 groups were clustered with other genus species, and 6 out of 7 groups of conspecific seeds appeared farraginous in the dendrogram.

结果表明：(1)80种草本植物的种子可以分成两类，第1类由禾本科、莎草科、蓼科和苋科植物的种子组成；第2类由菊科、大戟科、十字花科和伞形科植物的种子组成；(2)聚类图上，只有十字花科植物的种子能较好地与其他科的相区别；(3)在11组同属不同种植物中，有8组植物与亲缘关系不同的其他属的植物混在一起；在7组同种不同亚种或品种植物中，仅有1组植物被聚合在一起。

The distribution and harm of species of dominant weeds of lawn vary with different area, and the most harmful weeds belong 8 families, which were Poaceae, Asteraceae, Cyperaceae , Amaranthaceae, Euphorbiaceae, Polygonaceae, Fabaceae and Caryophyllaceae, about accounted for from sixty percent to seventy percent in all weeds in lawn.

摘要不同地区草坪优势杂草的种类不尽相同，禾本科、菊科、莎草科、苋科、大戟科、蓼科、豆科和石竹科等8个科的杂草种类和发生数量最多，约占杂草总数的60%~70%。
