但是我只对桂花树情有独钟!桂花,没有牡丹的美丽华贵,也没有玫瑰的艳丽丰姿;但她却有一股沁人心脾、令人百闻不腻的清香。
花开时,可谓“独占三秋压群芳”。
桂花的作用很大,可以泡茶、入药、做桂花糕。
她的香味不但让人感到如释重负,还有净化空气的作用,能抑制结核、肺炎球菌、葡萄球菌的生长繁殖。
她的用处是不是很多呀!桂花树四季长青,最高可达15米,树冠最大可覆盖400平方米的空间!她的树皮粗糙,表面呈灰白色;叶子的表面非常光滑,是椭圆形的,边缘有小锯齿。
我们的学校一共有4棵桂花树,2棵在操场上主席台的两边,另外2棵在校门前。
一到花季,像米粒一般大小的淡黄色花朵一簇簇地挂满枝头,一阵风吹过,大片大片的桂花飘落下来,就像下了一场“桂花雨”。
听了我的介绍,我想你也会喜欢桂花吧!介绍树木的作文350字篇二:家乡的桃树我喜欢家乡的桃树,我觉得桃树几乎成了家乡的一个标志,让人没有办法忘记。
春天,正是播种的季节,大家都在辛勤的播种。
这棵桃树争先恐后的抽出新的枝条,长出嫩绿的小叶牙。
狭长的枝条上开满了粉红的桃花,一簇簇。
像一片片彩霞,在云雾中欢笑着。
五月左右,圆圆的小桃儿挂满了树梢,沉甸甸的,我爱家乡的桃树。
嫩绿的小叶变成了翠绿的大叶了。
桃子有的像玛瑙,有的像翡翠,诱人极了。
还没成熟的桃子,一大半绿一小半红。
咬一口,有点硬,又酸又涩但酸中带甜,涩的很不是滋味。
刚熟的桃子半红半黄,吃一口,“呀”,甜津津的。
完全熟了的桃子更是没法说,只要咬一口,用嘴一吸,嘴里便灌满了汁水,甜的像喝了蜜糖一样。
当你吸完了汁水,肯定会大吃一惊,怎么只剩果皮和桃核呢?原来是熟透桃子的果肉大部分变成了汁水。
我喜欢吃桃子,我更喜欢家乡的桃树。
如果你也喜欢吃桃子,欢迎你五月份的时候到我的家乡来做客哦!介绍树木的作文350字篇三:家乡的梨树姥姥家的院子里种着一棵梨树,它有五米多高,跟大人的腰差不多粗。
大树给我们带来了什么好处作文大树给我们带来了什么好处嘿朋友们,你们知道吗?我们身边这些看似平凡无奇的大树,其实是最亲切最可爱的环保先锋哦!它们不懈地为我们带来各种好处,是自然界赐予人类的一份沉甸甸的礼物。
说实话,我从小就格外喜欢上了树木这种生命体。
它们枝叶茂盛,遮天蔽日,那郁郁葱葱的绿意简直就是视觉上的一大享受。
而且每每迎风而舞,摇曳生姿,又仿佛在向我们诉说着丰沛的生机。
我最爱在炎热的夏日,钻进树荫底下乘凉歇息了。
那种逃离燥热,投身于一片清凉中的惬意滋味,实在让人身心无比舒畅。
后来随着长大,我渐渐地意识到,大树对于我们人类的好处远远不止如此。
比如说,它们就帮助我们每天呼吸着新鲜空气。
还记得吗?大树叶绿素的光合作用,可以不断地吸收空气中的二氧化碳,并释放出氧气。
没有它们在沉默地为我们"造氧",我们只能干瞪眼看着地球上的生命渐渐枯竭。
而且,大树的存在还能为我们遮阴挡雨、纳凉避暑。
在城市里,它们犹如一面面天然的绿色"遮阳伞",为城市降温增湿。
更难能可贵的是,大树还通过土壤固化来为我们保护家园。
这一次偶然的亲身经历深深地印在了我的脑海里。
有一阵子我们镇上经常下暴雨,山坡上的泥石不时就会滑落下来。
有一回,我顺着山路上学的途中,看到上面坡地完全被冲刷干净了,唯独那些疏密分布的树木还卡在那里,一株株斜插向外,枝桠上缠满了黄泥。
村里的老人家告诉我,正因为它们扎根地下的枝叶,才阻挡了更多的泥石垮塌和滑坡,维系着整座山坡。
我这才恍然大悟,大树的根脉竟是如此坚韧有力,成为了大自然最出色的"固土员"啊。
因此大树除了给我们带来清凉的遮荫、清新的空气之外,它还以自身的生命力去保护我们的安全,让我们倍受温暖与惭愧。
我不禁深深地被这一份无私的奉献所打动,暗下决心一定要用行动去珍惜和呵护这些让生活如此美好的大树。
如今每当下课放学,我都会拉着几个好朋友在小树林里劳作一番,清扫落叶、浇水施肥,动不动就和爸爸妈妈聊起维护树木的重要性。
让世界知道树有多重要作文
树是地球上最宝贵的资源之一,对人类的生存和发展至关重要。
它们不仅赐予我们新鲜的空气和清洁的环境,还为我们提供木材、果实和药材等生活必需品。
树木是地球肺部的重要组成部分。
它们通过光合作用吸收二氧化碳,释放出氧气,净化了我们呼吸的空气。
如果没有树木,大气中的二氧化碳含量将大大增加,导致温室效应加剧,进而引发一系列环境问题。
树木为人类和野生动物提供了栖身之所。
许多鸟类和小动物依赖树木建造巢穴,寻求庇护。
森林也是保护生物多样性的关键所在,孕育着丰富的动植物资源。
再者,树木还发挥着重要的水土保持作用。
树根能够固持土壤,防止水土流失;树冠和树干能够减缓雨水冲刷力,调节小气候。
因此,在山区和沙漠地带种植树木,对于防治水土流失和生态环境恶化至关重要。
树木还能为人类提供木材、果实、香料、药材等多种产品,在我们的生活中扮演着不可或缺的角色。
木材是重要的建筑材料和能源来源,果实和坚果则富含营养;许多中草药材料也源自树木。
可以说,树木是人类赖以生存的根基,是维系地球生态平衡的重要力量。
我们应该珍惜树木,保护森林资源,为子孙后代留下一个绿色家园。
让我们一起努力,让世界知道树有多重要!。
种植树木的好处作文植树节的设立是为了提倡人民种植树木,鼓舞人民爱惜树木,提示人民重视树木。
树木对于人类的生存,对于地球的生态环境,都是起着特别重要的作用。
下面是我给大家带来的种植树木的好处作文6篇,以供大家参考!种植树木的好处作文1几十年以前,砍伐很少,并常植树造林,使山上的花草树木形成一片片,漫山遍野都是树。
一到春天,山坡上花花绿绿,河水清清细流,山水衬托,显得漂亮极了。
在花草树木的庇护下,不仅风景漂亮,而且也很少发生天祸水灾,甚至没有。
近几年前,砍伐猛增,植树造林很少,山坡上的花草树木渐渐削减,如今甚至变成了光秃秃的山坡,在没有这些植物的根系作为爱护和拉力的状况下,泥土很舒松,看上去似乎特别的肥沃,但每吹一阵风,就飞沙走石,满天灰尘尘,每下一阵雨,就使河沟填满稀泥,田地里填满了沙石,这样,莫非不使农夫们哀思?假如有一大片一大片树林的掩盖,树叶遮风挡雨,树根的根系汲取大量的水分,那能有如此大的水灾么?能有淹田冲地之事么?能给农夫带来哀思么?这些年来,由于受到前人的教训,农夫们糊涂起来,知道了植树造林的好处,于是乐观响应了政府提出“植树造林,禁止砍伐”的政策,并乐观付诸行动,从而,山坡上的花草树木又渐渐的开头恢复原貌,削减了天祸水灾的发生,也削减了淹田冲地之事的发生,田地中的泥土几乎肥沃如初,年年得到了好丰收。
这样,使农夫得到了好风气,过上了好日子,这莫非说植树造林没有好处吗?植树造林,不仅能绿化了山坡,而且也给农夫带来许多乐趣和安心。
综上所述,植树造林的确有了很大的好处。
种植树木的好处作文2植树造林的好处有许多。
首先,植树造林可以净化空气,树木在生长过程中,由于光合作用,能汲取大量二氧化碳等有害气体,从而使空气得到净化。
据科学家推算,地球上的树木。
草地每年为人类处理掉废气达200亿吨。
在当今这个工业发达的时代里,当人类正在为一件件高新技术产品问世而感到傲慢时,一场无声的灾难正静静地覆盖地球。
这就是--环境问题。

树木的作用的作文
本文是关于树的话题作文,仅供大家参考!
树木为人们带来很多,可以让人们在树下泡茶、聊天、乘凉,使人们可以快快乐乐在又凉爽、又写意的环境下避暑。
下面是小编整理的作文,欢迎查阅。
篇一:树木的作用的作文今天,我从《十万个为什么》书中知道了树木的作用。
原来森林是一个“绿色宝库”,可以吸收二氧化碳,制造出氧气;还可以吸收有毒气体。
它还有一个功能,就是净化废水。
这是因为,在废水中含有大量的磷、钾、镁、钙等矿物质,这些矿物质是树木生长不可缺少的养料,使得森林中缺少营养的树木获得了一定的肥料。
废水中的有毒细菌和病菌进入到森林中的土壤后,土壤有自己天敌。
而且,森林中的许多树木可以分泌杀菌素,会将细菌杀死,而树上细菌也会在紫外线和杀菌素的作用下难以逃脱死亡的命运,这样废水中的有毒成分就逐渐消失了,再流入地下和河流中的就不会造成污染了。
树木的作用非常大,是人类的好朋友。
所以,我们要多植树造林,保护树木,不要乱砍乱伐,减少用一次性筷子……。
小朋友,让我们从自己做起,保护环境.减少污染,让我们的生活更加美好!
篇二:树木的作用的作文树,是保护自然环境的卫士,是人类能持续生存在地球上的保证。
所以,我们要植树造林。
植树造林的好处有很多。
比如说,植树造林可为人树,是保护自
然环境的卫士,是人类能持续生存在地球上的保证。
所以,我们要植树造林。
植树造林的好处有很多。
比如说,植树造林可为人类提供氧气,净化空气,美化环境,有利于生态环境的保护。
树木有光合作用,树木在光合作用下会释放氧气,就像“绿色工厂”。
当我们吸进氧气之后又吐出二氧化碳时,树木会把我们吐出的氧气吸进去,然后释放出清新的氧气,让我们健康、幸福地成长!据统计,一亩树林每天能吸收67公斤二氧化碳,释放出49公斤氧气,足可供65个成年人呼吸用。
由于森林具有遮荫避风、树木呼吸和蒸腾作用,因此有成片树林的地方冬暖夏凉,可以避暑疗养,是我们休息渡假的首选。
树木还具有粘附空气中的尘埃的作用,使空气清洁、新鲜。
科学测试表明:一亩树林一个月可吸收有毒气体二氧化硫4公斤,一年可吸收尘埃20吨~60吨。
此外,树木在呼吸过程中,产生大量特殊空气,能治疗一些疾病,对人体有良好作用,比如,桦树、杨树、桧树等能分泌出植物杂菌素,可以杀死白喉、肺结核、伤寒、痢疾等病原菌。
树还可以降低工业区内发出的噪音,在道路两旁栽多种多样的树型、花果和翠绿的枝叶不仅可以美化环境,还可以为人们学习、工作和生活提供理想化环境。
植树造林对人类生活也很重要,我们的课桌、书柜、纸张等,都是用木材制作的,给我们的生活和学习带来极大的帮助。
它还能防止水土流失。
在山西、陕西以及边新疆一带,水土流失异常严重。
据调查,从1949年起,至1992年止,水土流失共367万平方公里,占国土的38.2%。
根本原因就在于植树少,无法固定沙土,所以,土
地就被风和水所侵蚀。
那么其它江河流域的水土流失要略比这一地区轻。
设想一下,如果大家不爱惜树木,无谓的砍伐,没有这些树为我们遮风避雨、释放氧气,我们还怎能生活在这么美好的地球上呢?因此我们要珍惜树木,多植树,多造林。
有句话说得好:“前人栽树,后人乘凉。
”我们现在植树造林,是在为后世子孙造福。
篇三:树木的作用的作文几乎每个地方都有树,无论在窗前、公园里、校园里,或者是街道上。
但我们常常忽略它们的存在及重要性。
如果没有了树,景色还会动人吗?每个地方变得僵硬、单调、枯燥,再也见不到树木花枝招展的景象了,世界从此枯萎,甚至连锁反应、后患无穷,危害到人类自己。
所以我们应努力让树木长存于这片树与人们共有的土地上。
树木为人们带来很多,可以让人们在树下泡茶、聊天、乘凉,使人们可以快快乐乐在又凉爽、又写意的环境下避暑,减少用冷气的时间、减少空气污染。
在一个树廊里,享受新鲜的空气,滋养身体,让身体、心灵上都享受无比的舒畅,多快乐!而随着四季的变化,我们可以观赏各种不同的树,会开花的、会结果的,有的在同一时间,有的在不同季节,绽放迷人风姿,让每个季节都能构成各种美丽的图画。
树也像一个家,鸟儿在枝头上欢唱、跳跃;松鼠在树干爬上爬下,轻快灵活,看到人们接近就匆匆躲藏;还有花开时,蝴蝶飞舞;夏天时,
蝉儿不停地鸣叫;许许多多小昆虫,热热闹闹以树为家。
树也因此常常存在人们的回忆中,童年在大树下的点点滴滴,都是美好的。
树总是默默的、无私的为人们奉献:果实拿去卖了; 树枝、树干,当建材、造木屋、做家具,充分满足人们的需求。
我们应当多种树,爱惜它,珍惜人世间有这么好的资源。
树丰富我们的生活,希望我们在接受树木无私的付出时,能饮水思源,不忘本,并深深记住,在这世界上,树木是多么珍贵、多么不可缺少。
感谢阅读,希望能帮助您!。
