苜蓿

Since the comprehensive development of western in china, the manpower grassland of clover blossom has gained marked achievement.

西部大开发以来，该区苜蓿人工草地建设取得显著成就，如何在干旱条件下提高苜蓿产草量，成为该区生态经济农业研究的战略课题。

Resembling or shaped like a leaf of the clover plant.

形状似苜蓿叶的似苜蓿植物叶或其外形的，或与之相似的

Forages of modernized diary farm in Zhangwu county were corn silage,Chinese wildrye and alfalfa. In Hailin farm, main forages were corn silage and Chinese wildrye,and there was alfalfa once in a while. All cow households fed corn stover as main forages.

彰武现代化奶牛场饲喂的粗料有玉米青贮、羊草和苜蓿；海林农场主要饲喂玉米青贮和羊草，偶尔有苜蓿的供应；所有养殖户都以玉米秸秆为主要粗饲料。

The results showed: 1 Alfalfas grown for different lengths of time had considerable influence on photosynthetic characteristics of which the most important was stomatal conductance followed by transpiration rate and the chlorophyll relative content. 2 Diurnal variation in Pn and Tr had two peaks, and an obvious midday depression. 3 The net photosynthetic rate was significantly positively correlated with photosynthetic radiation, stomatal conductance, the relative chlorophyll content, and transpiration rate. The net photosynthetic rate was significantly negatively correlated with intercellular CO2 concentration.

结果表明，1生长年限对苜蓿光合特性有较大的影响，对气孔导度的影响最大，其次是蒸腾速率和叶绿素相对含量。2苜蓿叶片净光合速率、蒸腾速率日变化均呈现&双峰&曲线，有明显的光合&午休&现象。3净光合速率与光合有效辐射、气孔导度、叶绿素相对含量呈极显著正相关，与蒸腾速率呈显著正相关，与田间CO2浓度呈极显著负相关。

Makes the decency coal, the pearlite and the vermiculite carries on between the root nodulebacteria and the alfalfa variety match as the matrix, alfalfas nitrogen fixation effect and thegrowing trend is higher than other two kind of matrix, the decency coal may first take the highlyeffective strain screens matrix.

以风化煤为基质进行根瘤菌与苜蓿品种之间的亲和性的匹配试验中，苜蓿的固氮效果和长势均高于珍珠岩和蛭石这两种基质。因此，风化煤可优先作为高效菌株筛选的基质。

Nine different aphid-resistant alfalfas and four cross bred F1 were used in this experiment to investigate better dosage in SSR technique system and to seek the best combination among factors.At last,the best SSR technique system was established. The Taq DNA polymerase was 0.2μL(5U/μL),the 10×Buffer(Mg2+Plus)was 2.5μL , the dNTP Mixture was 2μL ( 2.5mmol/L), the primer was 1.5μL (10μmol/L),the template DNA was 1μL,the ddH2O was 16.3μL ,and the whole system was 25μL.

以九个不同抗蚜级别的苜蓿品种及四个杂交F1代为试材，摸索SSR反应体系中各个影响因素的浓度和用量，确定适合苜蓿抗蚜虫基因定位的SSR反应体系：其中Taq DNA聚合酶0.2μL(5U/μL)，10×Buffer(Mg2+Plus) 2.5μL，dNTP Mixture 2μL (各2.5mM)，引物各1.5μL (10μM)，模板DNA1μL，ddH2O 16.3μL补足25μL。

The result provide a basic foundation to produce transgenic alfalfas that are resistant against salt stress by introducing Na+/H+ antiporter gene from synechocystis species pcc 6803.Key words gene engineering Medicago sativa L. hypocotyls callus tissue culture

本试验结果为下一步将来自蓝藻的Na+/H+ an-tiporter基因转入苜蓿，获得转基因耐盐苜蓿奠定了基础。

She also has four-leaf-clovers, clovers with four leaves on them.

她还有一个四叶苜蓿，四叶苜蓿也代表着幸运。

He let that small clover drop somewhere inside of a great patch of clovers a hundred miles wide!

他把小苜蓿仍到了—百英里见方的一大片苜蓿堆里！

When a four-leaf clover is found, it's considered lucky, since they occur on average only once for every 10,000 three-leaf clovers.

当一种四叶苜蓿被发现，它就被认为幸运的象征，因为几乎只有在10000片三叶草中才会找到一片四叶苜蓿。

I'm strongly against the death penalty — it's an eye for an eye.

我不赞成死刑——这是以牙还牙的报复行为。

And to get you the support you need, we're enlisting all elements of our national power: our diplomacy and development, our economic might and our moral suasion, so that you and the rest of our military do not bear the burden of our security alone.

并给你们所须的支援，我们正徵召国家所有各种的力量：我们的外交及发展，我们的经济力量与道德劝说，所以你们与其他军人不须要孤独地负起国家安全的责任。
