If a rest is in order, you might choose to take a meal at the Garden Restaurant or doing some shopping in the Garden Shop, both close by, but if you're ready to keep going, it's just a hop, skip, and a jump to the Fernery, the Rare and Threatened Plants Garden, and the Plant Sciences and Herbarium building, near the Administration and Reception Center.

如果是为了休息，你可能会选择服用花园餐厅吃饭或做一些园林购物店双方近在咫尺，但如果你愿意坚持下去，那只是跳、跳、蕨根、妄、珍稀濒危植物的花园、植物科学与植物标本馆大楼不久当局与接待中心。

You can get a sense of the growing conditions of these plants in different kinds of soil; you can see the difference between plants under row covers and the plants on either side of it; you can see the pests that destroy these plants, and even the weeds, which are so much like the plants around them isn't this just the mysteriousness of the natural world?

你能感觉到这些植物在不同的土壤中的生长情况；你能够看到那些在一块保护盖膜中间的植物与两边缘的植物间的差异；你能够看到那些破坏这些植物的害虫，甚至是那些杂草，与他们周围植物是何等的相似，这不就是自然界的奥妙吗？

Planted wetland had a removal rate of organic matter 2.2% lower than unplanted wetland in winter with plant harvested. In other seasons, the removal rate of CODCr in planted wetland was 3.2%～4.2% higher than that in unplanted wetland, while BOD\-5 was 1.8%～4.8% lower than that in unplanted wetland.

结果表明，在植物收割后的冬季，有植物湿地对有机物的去除率低于无植物湿地2.2%；在其他季节，芦苇湿地对污水CODCr的去除率比无植物的高出3.2%～4.2%，但对BOD5的去除率却比无植物的低了1.8%～3.4%。

The comparison of the effects on the two plants indicated that Ranunculusjaponicus, Aconitum sinomontanum,Ⅰ pomoea cairica, Aconitum gymnandrum and Anaphalis lactea showed significant effects on the two plants (their M values were separately -0.87,-0.82, 0.71,-0.68 and 0.62) and consequently these five plants were hopeful to be developed into new herbicides of plant origin.

综合比较对2种植物的综合化感效应指数差异，毛茛、高乌头、五爪金龙(Ⅰpomoea cairica)、露蕊乌头和乳白香青作用效果显著（其M差值分别是：-0.87、-0.82、-0.71、-0.68和-0.62），这5种植物有望开发新型植物源除草剂。

Plant was the main body of aspection changes.

豫北地区地处温带，较南方寒冷、干燥，四季变化明显，植物的季相变化也突出，大多数植物为阔叶落叶树和常绿针叶树，以及一些球根、宿根植物。

With the deflected succession of aquatic ecotype plant functional group,the dominance of mesophytes and xerophytes increased,while the dominance of aquatic and hygric plants decreased. However,there are only planting crops in the reclaimed wetland. In the composition of plant biotype functional group,the hydrophytes reduced quickly with the deflected succession and the dominance of perennial herbs is mostly marked,and there are only annual herbs in reclaimed wetland. Compared with primary swamp,the species diversity index of meadow is the highest,the swampy meadow follows,and the reclaimed wetland is the lowest.

植物的水分生态型功能群组成随湿地的逆行演替，水生、湿生类植物功能群的优势度不断减少，中生、旱生类植物功能群的优势度逐步增加，而在垦后湿地只有农作物；植物生活型功能群组成随湿地的逆行演替，水生草本迅速减少，陆生多年生草本增加占据优势，而在垦后湿地均为一年生草本；湿地植物物种丰富度、多样性指数由原生沼泽、沼泽化草甸到草甸依次增加，草甸为最大值，而垦后湿地则最低。

Flooding,as a kind of disturbance events,occurred with higher and higherfrequency over the world.To investigate the effects of flooding disturbance ongrassland vegetation and the soil,a comparatively thorough study was conducted onAneurolepidium chinense grassland in Songnen plain,Northeast China.The studysite was located in Sanjiadian National Rangeland in the territory of Da'an city,Jilirprovince,which was partly flooded in 1998.On the study site,Several transectssubjected to different flooding durations and intensities were designed for thecomparative study among them on such aspects as vegetation characteristics,seedbanks,vegetative propagation of rhizomatous plants,distribution patterns ofpopulations,interspecific relations,and physio-chemical properties of soil.Theresults were as follows:(1)Of the functional group composition of the vegetation,with the elongation of the flooding duration or the increase of flooding severity,theratio of hygric and hygro-mesic plants increase,while that of mesic and mesoxericplants decrease,of Therophytes changed unimodally,of Geophytes increased,whileof Hemicryptophytes decreased.

为弄清草地植被及其土壤环境对水淹干扰的响应，在松嫩平原羊草草地1998年部分遭受水淹的吉林省大安市三家甸子草场内设置了经历不同水淹干扰持续时间和不同水淹强度的样带，并在这些样带之间从植被特征、种子库特征、根茎植物的营养繁殖性能、种群分布格局、种间关系及土壤的理化性质等多个方面展开对比研究，主要结果如下：(1)在植被的功能群组成中，随干扰强度的增加和水淹干扰持续时间的延长，湿生、湿中生类植物功能群的优势度比例基本上是逐渐增加的，中生、中旱生类植物功能群的优势度比例则逐渐减小，而一年生植物的优势度比例呈单峰型变化，地下芽植物比例增加，地面芽植物比例减小。

But the Cologne plant technology is the domestic and foreign origination new technology, has the craft to be simple, the cost low, easy to promote and so on merits, not only may use in the economic plants fast breeding, moreover may use in the transgenic plant or be in imminent danger economic plants' fast reproduction, the promotion and the protection, asexual quick numerous has the universal significance to many kinds of plants, has the very high suitable value, the application scope is very broad.

而科隆植物技术是国内外首创的新技术，具有工艺简单、成本低、易推广等优点，不仅可用于经济植物的快速繁育，而且可用于转基因植物或濒危经济植物的快速繁殖、推广和保护，对多种植物的无性快繁具有普遍意义，具有很高的适用价值，应用范围十分广阔。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
