植树节手抄报素材内容
植树节是一些国家以法律规定的以宣传保护树木,并动员群众参加以植树造林为活动内容的节日。下面是关于植树节手抄报素材内容,**!
越来越多的人热衷于植树活动。然而与此同时,也有不少消息说,由于缺乏相关知识,每年植树活动中能够成活的树很少,即使是有专业人员负责后期维护,栽种过程是否科学合理也是成活与否的关键因素。为此,我们专门采访了北京植物园的魏钰女士。
在华北地区,3月中旬至4月下旬为种树的最佳时段,最好选在阴天与降雨前进行。种植时,在确定好树坑的位置后,可根据树种根系情况或土球大小以及土壤情况决定树坑的规格,一般应比根幅范围或土球大,直径应加宽40—100厘米,深度增加20—40厘米。
树坑的好坏对栽植质量与日后的生长发育有很大影响,因此要格外注意。树坑以圆柱形最好,以树干为圆心画圈,沿圈边向下垂直挖掘,直到达到规定深度,要保持上下垂直,大小一致,切忌挖成上大下小的锥形或锅底形,否则栽植踩实时会使根系劈裂、拳曲或上翘,造成不舒展而影响树木的生长。
挖坑时注意把表土与底土分开放置,并按相应位置回填。如果是坚实的上壤或建筑垃圾土则应该加大树坑的直径,并将坑底的土挖松;土质不好的应过筛或全部换土。在新填平与新堆土上挖坑时,应先在树坑附近适当夯实,挖好后的坑底也适当踩实,以防栽完浇水后土塌树斜。
栽植时,一人扶正苗木,一人填土,填一部分踩实一遍(若粘土不可重踩),直到填满后再踩实一次,填好的土要与原根颈痕相平或略高3—5厘米。
栽后应立即灌水,无雨天不要超过一昼夜就应浇上头遍水。水一定要浇透,使土壤吸足水分,有助于根系与土壤密接,才能确保成活。
往年3.12植树节主题
2009年的植树节主题是: 让森林走进城市,让城市拥抱森林。
2010年的植树节主题是: 与大树在一起。
2011年的植树节主题是: 追求绿色时尚,走向绿色文明。
2012年的植树节主题是: 义务植树共建绿色与谐家园,植绿护绿共创省示范文明城市。
2013年的植树节主题是:深入开展造林绿化,大力推进生态文明建设。

(1)树木的分泌物能杀死细*。空地每立方米空气中有3,4万个细*,森林里只有300-400个。植树造林是我们每个公民的义务,国家还专门规定了在三月十二日这天为植树节。植树造林对我们的学习、工作、生活等方面都有很大的好处。
(2)树可以减低温度,与提高湿度。30度气温可以降到二十几度左右。
人类对自然资源的不合理开发利用,是造成生态失衡的主要原因。乱砍滥伐、毁林开荒、过度放牧等,会破坏森林与草场,造成水土流失与土地荒漠化,使沙尘暴频繁出现。不合理的开发、占用土地,使耕地面积日益减少。
(3)树木能调节气候,保持生态平衡,树木通过光合作用,吸进二氧化碳,吐出氧气,使空气清洁,新鲜。一亩树林放出的氧气够65人唿吸一辈子。
(4)树能防风固沙,涵养水土,还能吸收各种粉尘,一亩树林一年可吸收各种粉尘20—60吨.。
(5)树林能减少噪音污染。40米宽的林带可减弱噪音10—15分贝。噪音的污染对人类的生活、学习、工作、休息等方面都造成了很大的危害,可以说是人们的“敌人”。因此我们更要重视植树造林。噪音还可以使人类在长期的生活中听力减弱、耳聋、变傻,心脏、血压、神经等出现异常。甚至,还能让人在长期的噪音煎熬下死亡。这样树林就能使噪音减小四、五倍。

1、植树节英语手抄报内容
March 12 is "Arbor Day". When we hear about arbor day, we will definitely think of going to plant trees. Of course, on that day, my family and I planted a small sapling at the door of our house.On Saturday morning, it was sunny. Seeing that my parents were going to work, I quickly stopped them and told my parents that today was arbor day, and they happily agreed.
My father carried a shovel in his left hand and a kettle in his right hand. My mother carried a small sapling. They hurried out of the door, while my sister and I jumped and ran out with them.
We came to a vacant lot and saw that the land there was very fertile and flat. My father put down the kettle and easily dug a big pit on it. My mother handed the small saplings to my father, and my father put the small saplings into the pit. Seeing that my sister and I had nothing to do, he asked me to bury the pit. I picked up the heavy shovel and pushed the soil in hard. I couldn't help sighing in my heart: Wow! Why is this shovel so heavy!
I really admire dad's strength. Thinking, thinking, I filled the hole, too. Next, it's the trampling work belonging to the "troublemaker" sister. I saw my sister walking towards the sapling, like a madman who was crazy. She stepped on and jumped on the soil with her feet. After a while, she finally completed the trampling work. My sister, she was sweating profusely. Finally, it was time for my mother to play. She carried the kettle, bent down, poured water on the saplings, and then gave me the kettle. Finally, I hurried upstairs with my sister.
Mom and dad went to work, and my sister and I rested at home, so we finished planting trees.
We have always believed that natural resources are inexhaustible and inexhaustible, and abundant resources seem to be a waste. However, when we observe the operation of nature, we will know that any kind of resources is not endless. We are always waiting and watching, watching each kind of resources exhausted, and looking forward to the next time will be better.Where there are trees, there is hope; Where there are trees, there are dreams; Where there are trees, there is joy; Where there are trees, there are mine Missing; Where there is you, there is my blessing: Happy Arbor Day!
Step in your footsteps, step on the dust all over the ground, and firmly carry out your conquest. Self improvement is the eternal road in life. Arbor Day comes, and plant a tree of friendship for you. I wish you success and happiness in life.
The most praiseworthy thing about the forest is its self-expression. Whether it is the handle of a tool, a dead tree toon, or every living branch, it records the blow of the wind. It always tells its own story. That's why wood has an attraction to people, not only the material itself, but a spirit of homologous coexistence and understanding. Few people will be indifferent to the feelings brought to us by pine trees. Their voices go straight into our hearts from the mountains. If we occasionally listen to the words of trees, all the problems of forest maintenance and preservation will disappear. Arbor day, a variety of trees!
Snow disaster, earthquake and flood. What can we do to save our earth? Plant trees, yes, be environmentally friendly and plant more trees.
Arbor Day is coming. Let's plant trees in our hearts and protect our environment together! Plant a pine to make it green; Plant a peony to make it red; Plant a sincere tree and sow the seeds of love. Arbor Day is coming. May you plant a good mood and good luck!
The small town we live in is a place with shady trees and beautiful environment, which is the result of people's afforestation and environmental protection for many years. I have also done my part for our beautiful small town - planting a small tree on the back mountain of my house.It was March last year. On a sunny morning, my mother and I came to the back mountain of our house with shovels and saplings and water. We chose a place with plenty of sunshine and wet land to plant small saplings. I couldn't wait to pick up the shovel and shovel it to the ground, but I only shovel a little soil. Then I shoveled it on the ground several times, but I still didn't shovel much soil. I asked my mother, "Mom, why can't I shovel much soil so hard?"
Mother smiled and said, "I'll teach you." My mother took the shovel in my hand and said, "look carefully!" Push the shovel out of the soil with one hand and then push the shovel foot into the soil with one hand at the same time. My mother stopped and asked me, "have you learned it?" "Learned." I picked up the shovel and scooped up the soil like my mother. Although it looked very clumsy, it was much better than at the beginning. I shoveled a few times.
A small pit appeared. Mother said, "you can plant trees." I took the sapling and put it in the center of the pit. My mother took the shovel to shovel the soil back into the pit, fill the pit, and then pat the soil in the pit with the shovel, and the tree will be planted. We'll water the little tree again and it's done.
In the future, I often water and cultivate soil for the small trees, which thrive day by day. Now my small tree has grown to more than one meter high, which adds a touch of green to our small town.
Today is Arbor Day on March 12. Under the leadership of my father and mother, my classmate Yin Zezhou and I went to forest lake to plant trees.Dad drove his car and slowly left the prosperous urban area and came to the quiet suburbs. The willows beside the road spit out fresh green buds, and the fresh air slipped into my nostrils. We are in a very happy mood.
Unknowingly, we came to the forest lake. Many little friends planted trees with their parents. We followed the adults to the tree planting place, and quickly grabbed two shovel, two small seedlings and a bucket, found a vacant land and began to plant trees.
Mom and dad gave us a demonstration, told us how to grasp the soil, first we should grasp the shovel with both hands, and push the back with the foot on the shovel, then we can dig the pit deeper and deeper. We dug up according to the instructions of our parents. I just dug a few times and felt tired and hot. I quickly took off my coat and went to battle light.
It was not easy to dig the pit deep. Unexpectedly, the more tired task is still waiting for us. We put the young trees into the pit and had to fill in the soil bit by bit. After that, I had to go again and again to water the seedlings. Although Yan Zezhou was bigger than me, he always asked me to carry water. I walked carefully with buckets in my hands, lest the water flow out and take a rest. Finally, I mentioned it to the small tree and let the small tree drink water.
Finally, we wrote our name on the sign and tied it to the tree with a red rope. We took a group photo with the small tree we planted. The small tree seemed to be a friend of mine, laughing with me.
I had a good time today. I'll come and see my little tree more when I have a chance in the future.
Today is Arbor Day. After dinner, my cousin and I prepared the shovel bucket, and our uncle rushed to take us to plant trees. Uncle pulled the car, carrying a bundle of small saplings and tree planting tools. The three of us didn't want to take the car. Following the car, the group set out in high spirits.Walking on the path in the field, the warm spring breeze brushed my cheek, itching and very comfortable. At the destination, uncle asked us who would dig the pit. I grabbed the shovel first and dug it. However, I made enough effort to eat milk and only dug a little land that was as big as my palm. My uncle grinning happily over the shovel and soon he dug a hole. I carefully put the saplings into the pit and straightened them. Cousin hurriedly helped fill the pit. Half of the pit was outside, "strong, don't fill it up, you have to water it!" Looking at my cousin's busy appearance, I laughed and shouted. Look at my little cousin. She's not idle. You see, she is staggering towards us with a small basin, her little face red. Uncle quickly picked it up and poured it into the pit. Ha, it's just wet enough for a layer of soil. We all laughed, and our cousin smiled shyly. After watering, we have to step on the soil. "Look at me, invincible strong feet!" My cousin shouted, rushed up with a vigorous step and frantically stepped on the soil around the small tree. Seeing this, I quickly shouted, "Zhuang Zi, slow down, don't step on it!" "No, don't worry!" My cousin is so naughty. I have nothing to do with him. I had to take my cousin to plant another tree.
After being crazy for a while, my cousin came to plant trees with us. Before long, a row of lovely little trees stood by the path. Looking at the little tree planted by myself, I realized the hard work and silently wished: little tree, I hope we can grow together and grow into a towering tree as soon as possible. Under the spring breeze, the little sapling seemed to hear my wish, nodded and thanked us.
Bathed in the spring, we sang and walked on the way home: "... Dear partner, dear little tree, may we share the sunshine and rain, and may we cherish this beautiful time until we grow into towering trees..."
Today is the anniversary of Dr. Sun Yat Sen and also the arbor day on March 12. In order to commemorate Dr. Sun Yat Sen's contribution to the country, the people of the motherland set today as a day to add new green to the motherland.It's spring now. In the morning, Xiao Hong and I went to the suburbs to plant trees. We walked happily on the road. We saw beautiful flowers, tall trees and a fiery red sun hanging in the air. The sun was shining on my head, and drops of sweat fell from my head.
When I got there, I took out a small shovel and dug a tree pit in a sunny place. Then I put a small sapling in. Xiao Hong held the small tree. I picked up the shovel and filled in the soil. In this way, the small sapling was planted. Xiaohong went to the river to fetch water with a bucket. When she came back, she slowly poured the water into the tree pit. I was so tired that I was sweating. I wiped the sweat on my head with a towel. Xiao Hong looked at me and laughed, and a passing bird also laughed.
The tree planting task was completed. When Xiaohong and I left, we were worried that someone would destroy the small tree, so we tied a red scarf on it, which said "love greening and defend the motherland". At this time, a bird stopped on the sapling, as if to say to me: "children, I will build a nest on it!" The little tree also seemed to say to me, "little master, don't go. You have added more greening. You will be rewarded by your mother."
Xiaoshu, I want to say to you, "you must thrive, and your efforts will make the motherland more beautiful!"
As the annual Arbor Day is approaching, we began to protect trees and trees. More than half of people think that trees and trees should be protected only on arbor day, but my view is just the opposite. We can't protect trees and trees only on arbor day, we should protect trees and trees all the time. Many people in the society are planting trees by themselves today. My parents and I are not weak and go to the park to plant trees together.We first found an open space in the park, and then dad picked up the shovel and began to dig a hole. Soon, a hole became in front of us. I said to Dad, "Dad, you're great." Dad replied, "of course! Ha ha!" I gently put the little tree? Put it in the pit and cover the soil with your hands on the roots of the saplings. I stepped on the soil with my feet again, just like massaging the saplings. At this time, my mother brought a bucket of water and asked me to water the young trees. I suddenly lifted the back of the bucket and the water flowed from the bucket into the soil. Mom looked at it, quickly corrected it for me and said, "it's not so watered. It should be watered slowly." After listening to this, I gently lifted up the bucket. The backwater slowly flowed into the soil. I was very happy. I quickly asked my mother to take a picture of the little tree for me. Oh, the little tree must be strong when it grows up.
Protecting the earth depends on everyone. Protecting the earth is the responsibility of everyone. If you want to live well, you must start with me.
Every year, March 12 is Arbor Day. This year's Arbor Day, I have become a primary school student. The school brigade organized us to participate in tree planting activities in the suburbs to improve the students' ability to take care of nature since childhood. Awareness of caring for the environment.It was a fine morning and the sun was shining on the earth. After we got off the bus to the countryside and got off, I held a shovel, bucket and carrying seedlings with my classmates. Come to the open space and start planting trees. I'm the first group. Our task is to water the young trees. Shi Ruoqi is the second group. Their task is to fertilize the young trees. Yu Dongli is the third group. Their task is to dig holes for small trees. Loosen the soil and plant small saplings. Everyone is busy doing what they should do and is doing it in full swing. In high spirits. There was a happy smile on everyone's face. After they finished the tree species, it was our group's turn to water the saplings. We went to the river to carry a bucket full of water to water the saplings. It's like watching the white water pour into the mouth of the saplings. They are so happy to drink it. They also say while drinking: "thank you for your hard work. Under your careful care, we will grow into useful talents to make human beings in the future." I'm very happy and proud after listening to it, I think that after many years, the small saplings planted here by my classmates and I will grow up one by one and become a large shady forest. At that time, how will we feel when we come here again! It is precisely because of people who love and care about nature like us. Our world will become better and greener.
This Arbor Day activity has really increased my knowledge and learned that only by loving nature, flowers and trees and getting along with them, our world will be more beautiful and rich.
Today is the annual Arbor Day. In order to contribute to nature, I went to plant trees with my "best friend" Ruan Shengyan. We chose Nanshan. So I took two saplings, Ruan Shengyan took water and shovel, and we set off.When we came to Nanshan, we began to look for a place. After looking for a while, Xiao Ruan found a wonderful place. There was plenty of sunshine and fertile soil. It seemed that this was the best place. I looked at it, Said, "let's do it. So I took up the shovel and dug it up. In order to make the tree strong, I dug a hole 30 centimeters deep and 20 centimeters in diameter, and just excavated the first spade. The fragrance of the earth came up to my nose. It was delicious. Digging a little bit always made a dig. It made me angry. I was hard boiled, and I dug up and dug for a while. Be accomplished, but I was sweating and weak limbs. I sat on the ground, I picked up the kettle and greedily sucked the water, ah! It's so comfortable. At this time, the breeze blows, and the woods make a loud noise, as if the woods are playing a welcome symphony for us. I think we should add new members to them, and they will thank us again. After a rest, my energy is replenished. We started working again, Xiao Ruan said, "you put the tree and I'll water it "When we said we would do it, I picked up the saplings and put them in the first dug pit, filled the soil first, and then stepped on the soil to fix the saplings, and Xiao Ruan immediately poured the water on them. Ha ha, it was a great success. We both clapped hands, and we had an unspeakable joy in our hearts. I think this is what people often call a sense of achievement! Touching the saplings, we reluctantly went down Mountain, on the way, my heart began to daydream. In another 20 years, this little tree I planted will grow into a towering tree. I couldn't help laughing.
It seems that today is a harvest day. We must also be a qualified little guard of environmental protection.
On arbor day, my parents and I participated in the arbor day competition held in the community. Although we didn't win the first place in the end, we were also very happy to see the small trees we planted."Ready to start" just listened to the host's order. My parents and I quickly took the tools and ran to a vacant lot to start, "come on, I'll dig a hole first." my father had great strength, so he was the first to play. He waved a small hoe and soon dug the hole. My mother, who was waiting for the opportunity, saw that the hole had been completed, Immediately put the little sapling in his hand, and then get out. My father buried the soil together, so that a small sapling could be buried, yeah! Success. Next, just wait for me to come on and pour some water. Just when we were complacent, cheers came from there.
I turned around and saw that their group had been completed. It seemed that we were a little behind them. Seeing that we were the champion, I didn't expect Cheng Yaojin to kill on the way. I suddenly looked like an eggplant, listless and disappointed, My mother came up to comfort me and said, "don't be sad. You see, the saplings have been planted so well by us. One day in the future, we will see this little tree grow into a towering tree. How happy it is! Then the tree will play its role and help us purify the air". After listening to my mother's words, I nodded with approval. I will plant many trees next year, In this way, it will be lush everywhere. In summer, we can enjoy the cool under the big tree.
At this time, a cool wind blew, as if I really stood under the big tree in summer, and the big tree still greeted me! It is really comfortable.
