一、前言润布勒苜蓿(Medicago medid Pers.)原产加拿大萨斯喀彻温省。我国于1972年引入,经我所几年来的引种观察和品种比较试验认为,其抗寒、抗旱性能优于我国北方现有大多数紫花苜蓿栽培品种。其产草量较高,根颈宽扁,侧根发达并有根蘖特性,有利于抵御不良环境。为进一步探索其在不同自然地带的适应性及生产性能,1980～1982
I. Introduction Medicago medid Pers. Is native to Saskatchewan, Canada. Our country was introduced in 1972. After several years of introduction observation and variety comparison experiment in our country, it is considered that its cold resistance and drought resistance are superior to most existing alfalfa cultivars in northern China. Its high yield, root wide neck, lateral root development and root tiller characteristics, is conducive to resist the bad environment. In order to further explore its adaptability in different natural zones and production performance, 1980 ~ 1982

算上这次，他已经是第三次被同学齐心合力逐出“组门”。唉，这个李子，的确让人头疼！ 开学初，按照学校的小组合作学习要求，我们重新划分了小组，李子分担的工作是检查小组地面卫生，或许这是他能够胜任的唯一一项管理工作。结果，就这么点事，他竟然也干得一塌糊涂。管理能力差也就算了，但执行其他项目组长分配的任务，他完成得也是一团糟。譬如数学组长找他收作业，他根本不搭理人家…… 还不到一周，各项目组长就被他弄得

我深以为，为师者必须多学习多运用心理学知识，深刻地把握学生的心灵状态，敏锐地作出判断，选择智慧的、艺术的、“悄然无声”的教育方式，让教育贴着学生的心灵飞扬。之所以又一次有这番感慨，是因为前段时间我们班参与的一场拔河比赛。 这是一场争夺冠亚军的比赛。尽管孩子们竭尽全力，但还是与冠军称号失之交臂。回来的路上，孩子们本来就非常沮丧，又听说主力队员吴纳海居然不打招呼“临阵脱逃”，更是义愤填膺。我的心中也
