淹水

If you are in a flood area, consider what mitigation measure you can do in advance.

假如你在淹水的区域，思考在淹水之前你可以采取哪些减灾的工作。

The decomposition rate of organic matter in submersed is obviously larger than that of organic matter unsubmersed after input of nitrogen,suggesting hy...

在非淹水条件下，氮素输入后有机物质的分解速率明显大于淹水条件，说明水文条件和氮素输入对枯落物的分解过程都有重要的影响，只是在不同环境条件下的响应存在一定的差异。

Water stress is one of the most important abiological stress to maize seedling .In this study, we arm to identify the sensitive stage of maize seedling to water stress and select the material which tolerance to flooding. And we use waterlogging tolerance index to identify the sensitive stage of maize seedling. we have studied 20 inbred lines of maize which seedlings under water stress in three stage. The result show that the three leave stage is the most obvious stage to flood stress. In addition, we have analyzed ten of the inbred lines to re-act the waterlogging tolerance index. The result show good re-action. And the result also show that waterlogging tolerance index is a credible index to select waterlogging tolerance materials in seedling.

涝渍是玉米苗期主要的非生物逆境胁迫之一；本试验通过对20份玉米自交系进行苗期的淹水对照试验，采用了三个处理时期，并利用耐渍系数作为指标进行敏感时期的鉴定，结果表明三叶一心期是淹水的相对最佳时期；同时利用其中10份自交系对耐渍系数的重演性进行了分析，结果表明其重演性很好；同时结果还表明耐渍系数是耐渍性鉴定的一个可靠指标。

在发表于8月1日出版的《环境科学与技术》的一篇论文中，英国洛桑研究所的赵方杰及其同事比较了淹水种植的水稻与旱作种植的水稻之间的砷水平，淹水种植水稻是南方国家最传统的耕作方法，而旱作种植水稻则指的是不把水稻根部浸于水中的做法。

Total submergence largely decreased biomass production and growth in length,with less effect on shoot numbers.Increased elongation of the growing internodes of up to 140% is caused by submergence.Nutrient such as N,P,K do significantly affect on growth.No mater lack of any element will decrease the biomass,the result same as the oligotrophic conditions.But lack of phosphorus is the worst mater.

而淹没式淹水可能使生物量降低，但是植株的高度有所增加，因为淹水可以使芦苇的节间高度提高140％；对根茎的数量没有很明显的影响。N、P、K等营养元素对芦苇生长也具有重要的作用，无论缺少哪一种对芦苇生长都不利，跟完全贫营养状态没有明显的区别，但是缺P时芦苇生长是最差的。

The overview discussed the 8 factors affected the survival rates, and the plantable tidal flats and the threshold of waterlogging time of mangroves seedlings. The different inundation classes of mangrove and the critical tidal level fits for mangroves forestation were summarized.

本文从影响红树林造林成活率的8种自然因子和人为因子出发，着重探讨了滩面高程和临界淹水时间，并对国内外对红树植物潮汐淹水的等级的确定，以及国内各地造林过程中的宜林临界线的测定进行了综述。

In this study, the responses of Spartina alterniflora in terms of the parameters of chlorophyll fluorescence and chlorophyll content to continuous waterlogging for two years and to restoring after continuous waterlogging for one year were investigated.

同时，应用叶绿素荧光技术，分别研究了连续2年持续水淹和淹水1年后排水恢复自然生境条件下，外来入侵植物互花米草叶绿素荧光动力学参数及叶绿素含量的动态变化。

We've come out of nowhere, literally, nowhere, autumnal towns marked for destruction by a phantom hand; houses held underwater, every bed a sunken tub, tools drowned between rows, every keyhole caulked; clouds hallucinating girls asleep on a wedge of wedding cake; the white rose, among the greatest of liars beginning to show the debilitating effects of fame, the ever-popular blaze placates a vase; the bad sons of thunder beating back a strand of light; someone who knows nothing apart from the rain standing on a chair in muddy legs; the roses blown into their cumulonimbuses, and someone whose glove is recovered, a face that doesn't come clear, a face drawn under an umbrella, beautiful, charcoal, beautiful, like words that never get old, the sons of thunder beating

我们来自无处，纯粹意义上，无处置身，秋天的小镇已被一只无形的幻影之手作上毁灭的记号，房屋们都淹在水下，每一张床成了淹水浴盆，工具没在水滩里，每个洞眼充塞着。云层屯集着像女孩们昏睡于层叠的蛋糕边缘。白玫瑰，在巨大的谎言中，显露渐渐虚弱的光彩。和曾经眩目光芒抚慰着的花瓶。雷电的儿子们回击着一线光亮，有人不知情地站在泥泞的高椅子上，玫瑰被吹向积雨云，有人找到了她的手套，看不清楚的脸，从伞下移出，美丽的，黑炭似的，美丽的，像语言从来不会变老，雷电的儿子们回击着

The plant height (160 cm) and the amplitude of Deep water (50 cm) scenario were higher than Shallow Water (0 cm) scenario, while that of Draught (20% water content) scenario did not increase and some of the sedges died.

漂筏苔草无性株地上茎茎粗随着淹水深度的增加而增加，生长季茎粗的变化主要发生在6月份，其次是5月份和7月份，8月份茎粗变化微小（在50cm淹水状态下）。

Soil solution samples were obtained by centrifuging fresh soil samples.

结果表明，淹水后土壤溶液中DOC浓度在淹水初期明显增加，而后逐渐下降。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.
