植物的

Grade 1 students planted many different plants in groups. Before each class, teachers would ask students to observe the changes of the plants carefully and make a record. To get to know more about the usage of plants, kids went to the market to do a survey. They were very surprised to see many products are made of plants; They also did an experiment to get the chlorophyl from the leaves.

这两周，一年级的同学们分小组种植了各种植物，每次课前老师们都带领学生认真观察植物的变化，辅导他们做观察记录，孩子们乐此不疲；为了了解植物的作用，同学们去菜市场做调查探究，他们惊奇地发现植物与我们的生活息息相关；我们还让学生们走进实验室，学习如何提取叶绿色，感受科学试验的神奇。

The phytoplankton community was mainly composed of Cyanophyceae, Euglenophyceae, Bacillariophyceae, and Chlorophyceae, and the dominant species were Oscillatoria subtillissima, Dactylococcopsis irregularis, Euglena caudata, Melosira granulata, Cyclotella meneghiniana, Chlorella vulgaris, and Scenedesmus quadricauda. The main environmental factors affecting the distribution of phytoplankton species in July were ammonium-nitrogen, dissolved oxygen, water temperature, and total phosphorus, while those in September were pH, water temperature, dissolved oxygen, transparency, and total nitrogen. Water transparency and zooplankton were the main factors affecting the biomass of Cryptophyceae, Pyrrophyceae, and Bacillariophyceae; while nitrogen, phosphorous, and dissolved oxygen were the main factors affecting the biomass of Cyanophyceae, Euglenophyceae, and Chlorophyceae.

结果表明：调查期间共鉴定出浮游植物384种，隶属于8门，浮游植物密度范围为2.01×105～57.60×105 cells·L-1；群落组成以蓝藻、裸藻、硅藻和绿藻为主，主要优势种有细微颤藻、无常蓝纤维藻、尾裸藻、颗粒直链藻、梅尼小环藻、普通小球藻、四尾栅藻等；7月影响浮游植物分布的主要环境因子依次为铵态氮、溶解氧、水温和总磷，而9月的pH值、水温、溶解氧、透明度和总氮含量对浮游植物的分布产生影响较大；其中，透明度和浮游动物量是影响隐藻、甲藻和硅藻藻类生物量的主要环境因子，而蓝藻、裸藻、绿藻主要受水体氮磷营养盐浓度和溶解氧的影响。

Mercury frequently rules herbs that are tall, slender and have a feathery foliage.

这些植物的构造通常有明确的轻的特征，完全与那些更加坚实的植物像紫草科植物毛蕊花属的植物有着明显的不同。

This text elaborates the present condition of the our country wilding resources and the protection work and endangers the plant existence and protects various factor and plants of the work to protect the importance of the work, putting forward to protect the counterplan and the suggestion of the wilding.

本文阐述了我国野生植物资源和保护工作的现状、危害植物生存和保护工作的各种因素以及植物保护工作的重要性，提出了保护野生植物的对策及建议。

But K+ content in every organ of A.commans persicoides rootstocks was higher than that of other two almond rootstocks;the ratio of Na+/K+ in Amygdalus communis L.was higher than that of other two rootstocks.

盐逆境下植物器官之间Na+的区域化分配往往决定着植物整体水平的耐盐能力，Greenway和Munns提出，非盐生植物通过在根部贮存较多的Na+，以阻止Na+在地上部积累，有利于增强植物的耐盐性[1]。

Biomass of 10 plant species including Castanopsis fargesii,Pleioblastus amarus, Lindera strychnifolia,Vaccinium bracteatum,Ficus simplicissima(approximately account for 37%of total plant species in shrub layer) account for 84.15%of total biomass in shrub layer.Biomass of Woodwardia japonica and Blechnum orientale account for 93.3%of total biomass in herb layer.

在灌木层中，丝栗栲、苦竹、乌药、乌饭、三龙爪等10种灌木层植物(约占总灌木层种类的37％)占灌木层总生物量的84.1％；在草本层中，狗脊和乌毛蕨2种植物占草本层总生物量的93.3％，这说明林下灌木层和草本层植物的生物量主要集中在少数植物种类中。

The plant important value of Simpson and Shannon wiener in Jing zhou ancient wall are measured and illustrated. The important value of herb and liana and other relevant data are measured and illustrated. Pterocanfa stenoplera, Broussonetia,Papyrifera, Corydalis, Rabia,etc are selected.

测定了荆州古城墙植被中乔木的Simpson多样性指数值和Shannon-wiener多样性指数值，测定了草本与藤本等植物的重要值及其他相关数据，并得出B样方的植物多样性数值最高、I点的植物多样性数值最低等结论，筛选出枫杨、井栏边草、土牛膝、紫堇、薏苡等乡土植物。

The results of COS effects on fruits, vegetables, cut flowers, lily bulbs and potted ornamental plants showed that there were no phytotoxic effects of COS on fruits and vegetables under the condition of COS with the dosage of 40g/m^3 and for an exposure time of 2h.

COS熏蒸处理对水果、蔬菜、鲜切花、百合种球和盆栽观赏植物影响的研究表明：用剂量为40g/立方公尺的COS熏蒸2h后，COS对水果、蔬菜不产生药害，对果蔬外观和品质无影响；对植物的花朵无药害，但对植物叶片，特别是兰科、凤梨科等多肉质植物有较大药害，处理后的植物叶片出现脱水现象。

The correlation was attributed to the three types of plants:(1) the ephemerals plants;(2) the plants that had the transient soil seed bank or the aerial seed bank;(3) the plants of mainly vegetative propagation.

土壤种子库特征以及与地上植被的关系主要受以下几种植物的影响。1。短命植物；2。仅形成短暂种子库或是大部分时间形成空中种子库或土壤外种子库的植物；3。种子繁殖能力弱而营养繁殖能力很强的植物。

Considering the three principles of the plant indicator for mineral exploration,namely certainty,sensitivity and feasibility,this paper evaluates comprehensively the indicating functions of the eight plants,on the basis of some quantitative indexes such as the relation coefficient between plant ash and ore-forming element,concentration coefficient,etc.

文摘：在滥木厂和杨家湾铊矿床对芒箕、南烛、榔榆、大金发藓、蜈蚣草、石松、黄花草、醉鱼草等8种植物取样145件，在提出确定找矿有效指示植物三原则(确定性，敏感性，可行性)的基础上，依据植物灰分与底质成矿元素相关系数、植物灰分富集系数和衬度系数，较全面地分析和评价了8种植物的找矿功能；讨论了其异常的分布与断裂带、蚀变带、矿化带以及工业矿化之间的关系，并指出了其找矿意义。

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。
