Let environmental education "live".

The school moved the classroom into the forest

On the morning of the 3th, the students of Danzishi Primary School in Nan'an District moved their classes to the Nanshan One Tree Scenic Area, and the students expressed their love for spring, nature, and yearning for the future by reciting "Symphony of Green Leaves" and singing and dancing "A Little Sapling".

On the occasion of the Qingming Festival, the students also recited to remember the martyrs and pay tribute to the heroes.

Yang Jixian, director of moral education at Danzishi Primary School in Nan'an District, Chongqing, said that in order to make environmental protection education "live", the school explains plant knowledge through the "Science" class on a daily basis, and the "Ethics and Rule of Law" class explores the relationship between man and nature. This activity moved the classroom to Nanshan, where the children touched the soil with their hands and watched the trees grow, an immersive experience that cannot be replaced by textbooks. Just like the poems written by the students for the event: "The small shovel digs the pit of hope, and the water waters the green dream", which is the best life education.

Yang Jixian said, "Planting a tree is not only about planting a sapling, but also about planting responsibility and inheritance, as well as hope for the future." ”

The tree planting activity was full of harvest

At the scene, under the leadership of Mr. Wang, a science popularization officer of Nanshan Botanical Garden, the students walked through the long stone steps, walked between the mountains and forests, and came to the tree planting destination.

"In spring, when the temperature is relatively stable and there is plenty of moisture, planting trees at this time can better allow the plant roots to recover." According to Mr. Wang, if you want to plant a sapling, there are many conditions and requirements. For example, the soil nature, climatic conditions, and landscape of each place are different, and it is necessary to choose a suitable sapling for planting in order for the tree to grow more lushly, and it is also necessary to regularly fertilize, cultivate soil, and weed, after all, "three points of cultivation and seven points of nutrition".

"How long does it take for a small sapling to grow?" A classmate asked. Mr. Wang explained that the growth period of each tree species is different, and trees such as shrubs will grow faster; Arbors grow a little more slowly.

"This year, the sapling we planted was Nanmu. It is a fireproof plant and also belongs to the group of trees. In three or four years' time, it may grow several meters high. Mr. Wang also taught the students the process and skills of planting saplings on the spot.

For example, when planting trees, the first thing to do is to choose plants. Choose healthy plants that are free of pests and diseases; When digging a pit, it is necessary to dig a pit according to the condition of the sapling, the diameter of the pit needs to be 50/0 larger than the root or soil ball, and the depth should be determined according to the depth of the root, generally 0-0 cm more than the depth of the original root. For example, the depth of the roots of the tree is 0 cm, and it is enough to dig 0-0 cm. Control the distance of the pit well, not too dense, to prevent the sapling from growing up in insufficient sunlight. At the same time, remember to remove stones, cinders and other debris in the pit to keep the soil loose.

"When the sapling is placed in the tree pit, hold the lower part of the trunk in your hand, place the sapling in the middle of the pit, try to make the trunk vertical, and then backfill the soil into the pit." Mr. Wang emphasized that the backfilled soil should be filled twice, the first time buried halfway through, and it should be stepped on. After stepping on it, fill it with dirt and step on it again. Finally, pour enough water on it.

At the end of the training, everyone divided into groups, grabbed tools, and started the tree planting action.

"You will support the saplings, and I will fill in the soil." In the tree planting, the students worked together, some of them were skillful, and some of them were jerky. Some students said that this was their first time planting trees, and they were very excited, and they also learned a lot of ways to plant trees, which can be described as full of harvest. They believe that in planting, it is the most difficult to fill the saplings, the strength is not grasped well, and the saplings are too solid, and they are afraid that the water absorption of the saplings will not be good; It's not true, and I'm afraid that it will be blown crooked by the wind. Fortunately, with the help of volunteers from the Chongqing Urban Improvement Volunteer Service Corps, the students' trees were planted relatively smoothly.

Green seeds are sprouting in the hearts of teenagers

At the scene, some students told reporters that through tree planting, they have a more intimate contact with nature, and they also know that a piece of green forest is not easy to come by, and they are willing to be the guardians of the environment, contribute their own strength to the protection of the human ecological environment, and create a better future with everyone.

Some students also said: "I think the greatest significance of planting a tree is to witness it grow upwards in the sunshine and rain, from a slender seedling to a towering giant tree, when the branches and leaves are luxuriant, it will protect the environment, protect the ecology, and beautify the surrounding environment, bringing vigorous vitality to heaven and earth." ”

"I want to grow with the little tree, and in time, it will grow into a towering tree that people can look up to." Liu Jie, a teacher from Danzishi Primary School in Nan'an District, said that environmental protection is not only an activity, but also a slogan, but also a habit and a way, hoping that through such activities, students can deepen their awareness of green environmental protection, so that they can better understand the profound meaning of "lucid waters and lush mountains are invaluable assets, and protecting ecology is protecting the future". Teacher Liu Jie also hopes that by holding hands with small hands, more families can join the ranks of green environmental protection and protect our ecological environment together.
