American schools begin in September after a long summer holiday. There are two terms(学期) in a school year; the first term is from September to January, and the second is from February to June. Most American children begin to go to school when they are five years old. Most children are seventeen or eighteen years old when they finish high school. High school students take only five or six subjects(学科) each term. They usually go to the same class every day, and they have homework for every class. After class, they do a lot of interesting things.

第一章:林木种子
凡在林业生产上可利用作为播种材料的任何器官或其营养体的一部分,不论它由什么部分发育而来,也不论它在形态构造上简单或复杂,只要能作为繁殖后代的,都统称为种子(判)
林木良种是指通过审定或者认定的林木种子,在一定区域内,其产量、适应性、抗性等方面明显优于当前主栽材料的繁殖材料和种植材料。
林木品种是指经过人工选育或者发现并经过改良,形态特征和生物学特征一致,遗传性状相对稳定的林木群体。
林木的优质种子应具备以下几个基本条件:1纯净一致2饱满完整3健全无病虫4生活力强。
树木的一生有两个发育周期,一个是大发育周期,一个是小发育周期。 一般把实生树木的一生按年龄和发育特点可划分为三个阶段:幼年期、成年期、衰老期。 一般喜光、速生的阳性树种幼年期较短,开始结实早;耐荫、生长缓慢的树种幼年期较长,开始结实晚。如桉树、油桐的幼年期为3-6年,杉木6-8年,华北落叶松14年左右,而银杏20年左右,冷杉、云杉的幼年期更长,为50-60年。
影响树木的结实年龄主要有遗传因素、树木起源因素、外界环境因素等。
在某些特殊情况如土壤贫瘠、干旱、病虫害、火灾等的影响,林木也会过早结实。主要有遗传因素、树种起源、环境因素。
环境因素:改善种子园、母树林的营养条件、光照条件、促进林分结实。
种子的形成和发育一般经历花芽分化、传粉、受精、种子发育、成熟、脱落等过程。 种子的成熟:1种子的生理成熟2种子的形态成熟3种子的生理后熟。
种子虽然表现出形态成熟特征,但因胚未发育完全,或有抑制物质存在,不具备发芽能力,还需经过一段时间发育,才能形成发芽能力,这种现象称为种子的生理后熟。
林木结实稳定程度的四种类型:1结实极不稳定(夏橡、欧洲白蜡、欧洲云杉、西伯利亚落叶松)2结实不稳定(欧洲赤松)3结实稳定(欧洲白榆、疣皮桦)4结实相当稳定(西伯利亚白杨、柳、白蜡和多数灌木)。
产生大小年现象的主要原因是树木的营养状况。
影响林木结实的因子:1环境因子2内在因子3生物因子。 环境因子有:光照、土壤、气候、天气条件。
内在因子有:1母树年龄及生长发育情况。一二级木及处于壮年期的母树种子产量高,质量好;三四级木和处于青年期的母树种子产量低,质量差。2开花结果习性。
单性花:雌雄同株但异熟,花期不一致,(如核桃雄花先熟型)、雌雄异株(银杏、油桐、毛白杨雌花先熟型)另外,在存在单性结实现象,如黄连木、马挂木、松属。
强迫休眠有杨、榆、桑、落叶松、马尾松等种子。
种子成熟后,即使有了条件,也不能很快的萌发或发芽很少,这种情况称为生理休眠,或深休眠。如红松、白皮松、椴树、黄菠萝、山楂、黄栌等种子。
生理休眠包括:1初生外源休眠2初生内源休眠3初生综合休眠。
种子萌发分为吸水膨胀的物理阶段、停滞萌动的生化阶段、胚根生长发育(发芽)的生理阶段。
种子萌发要求一定的外界条件,其中必需因素为水分、温度和氧气,但光照、二氧化碳浓度等对种子萌发也有一定影响。
通过机械擦伤、酸蚀、水浸、层积或其它物理、化学方法,解除种子休眠,促进种子萌发的措施称为种子催芽
种子催芽分为:1浸种催芽2层积催芽3药剂催芽。
