狐尾

Bristlecone Pine, common name for a cone-bearing evergreen tree native to high, dry mountainous areas in the western United States.

狐尾松是一类生长在美国西部干燥高山上的结松果的常绿树木的共称，因为松果上的鳞片长得像狐尾而得称。

Only two scattered populations of the trees exist—the Rocky Mountain bristlecone grows in Colorado and Utah, and the Great Basin bristlecone is found primarily in the White and Panamint mountains of southeastern California.

这种树木目前只分布着两个种群：科罗拉多和犹他的洛基山狐尾松和加州东南部的白山和Panamint山地的大盆地狐尾松。

As an extension to the "973" Program of National Planning key basic research project -----the study of China lake nutrient over-enrichment process and the mechanism of blue alga outbreak, this paper introduces our experiments as below:(1) Experiment on heavy metal absorption and disorption abilities of Ceratophyllum demersum , Hydrilla verticillata and Myriophyllum triphyllum, in order to campare their absorption capability .

本文在前人的研究基础上，依托国家&973&国家重点基础研究规划项目&湖泊富营养化过程与蓝藻水华暴发机理&，开展了下列工作： 1、选取狐尾藻、金鱼藻、黑藻三种大型沉水植物作为研究对象，通过对重金属离子铜离子的吸附及解吸实验，比较其三种沉水植物之间吸附能力的大小； 2、选取狐尾藻、黑藻为研究对象，研究了重金属离子铜离子对沉水植物的胁迫作用及铜离子在植物体内的富集情况； 3、选取黑藻为研究对象，研究了沉水植物在富营养条件下不同浓度的氨态氮和硝态氮对沉水植物的生理生长的影响。

During the experimental conditions, the activitys of SOD, POD and MDA of Ceratophyllum demersum L changed greatly, and raised rapidly in the late of experiment, which indicated that those two submerged macrophytes got more nutrient stress than Myriophyllum spicatum L, and the nutritional stress-resistant ability of Myriophyllum spi-catum L was higher than those two submerged macrophytes in the medium nutritional condition.

在本试验条件下，黑藻生物量小，而金鱼藻SOD活性、POD活性和MDA质量分数变化幅度大，在试验后期急速上升，表明这两种沉水植物受到的营养盐胁迫较狐尾藻大，而狐尾藻在中营养水平下的耐营养盐胁迫能力较强。

The results showed that during the 45 days experimental time the fresh weigh of Myriophyllum spicatum L, Hydrilla verticillata L and Cerato-phyllum demersum L were 0.92 g, 0.27 g, 1.11 g and 0.56 g, 0.41 g, 0.87 g in medium nutritional condition TN 1.86 mgL^(-1; TP0.087 mgL^(-1) and eutrophic condition TN 2.47 mgL^(-1; TP0.16 mgL^(-1), respectively. The largest single plant biomass of Myrio-phyllum spicatum L and Ceratophyllum demersum L in in middle nutritional condition were over 39% and 22% higher than those in eutrophicated condition, but that of Hydrilla verticillata L was less than 51%, which shown that Myriophyllum spicatum L and Ceratophyllum demersum L grow better than Hydrilla verticillata L in middle nutritional condition.

研究结果表明，在45 d的培养过程中，狐尾藻、轮叶黑藻和金鱼藻在中营养TN1.86 mgL^(-1； TP0.087 mgL^(-1)和富营养TN2.47 mgL^(-1； TP0.16 mgL^(-1)水平下的单株最大生物量分别是0.92、0.27、1.11、0.56、0.41和0.87 g，狐尾藻和金鱼藻在中营养水平下单株最大生物量分别较富营养水平下高出39%和22%，而黑藻在中营养水平下单株最大生物量较富营养水平下低了51%，表明狐尾藻和金鱼藻在中营养水平下的生长较黑藻好。

General analysis indicates that Myriophyllum spicatum L.Panicle shape of the absorption of chromium Cr6 + concentration and treatment exist between the concentration of significant positive correlation with Myriophyllum spicatum L.can pollute the environment in better enrichment of chromium, the background environment The higher concentration levels of heavy metals, plant accumulation of heavy metals in higher concentration levels, the application of plant technology for the repair of heavy metal pollution on the environment to provide a scientific basis on Myriophyllum spicatum L. of heavy metal pollution of wetland restoration has great potential.

综合分析表明，在一定范围内，穗状狐尾藻对铬Cr6+的吸收富集含量随处理浓度升高而增大，说明穗状狐尾藻在污染环境中能较好地富集重金属铬，从而得出在一定范围内，环境背景中重金属含量水平越高植物富集重金属的含量水平也越高的结论，这就为应用植物技术修复重金属对环境造成的污染提供科学依据，而穗状狐尾藻对湿地重金属污染具有较大的修复潜力。

Both Cd2+ and Cr6+ destroyed Pistia stratiotes and Myriophyllum spicatum in the polluted solution,and Myriophyllum spicatum resisted Cd2+ and Cr6+ stronger than Pistia stratiotes,but Pistia stratiotes resumes more quickly than Myriophyllum spicatum.So in order to achieve better effects Pistia stratiotes and Myriophyllum spicatum should be planted mixed.

Cd2+和Cr6+对大薸和穗状狐尾藻都产生了不同的毒害作用，而穗状狐尾藻的耐Cd2+和Cr6+的能力要强于大薸，但穗状狐尾藻的自身恢复能力要小于大薸，因此为了达到更好的净水效果，大薸和穗状狐尾藻应混合种植。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
