In early spring and March, when the grass grows and the warbler flies, the cold of winter has not faded, and spring has quietly come to us. Spring breeze blowing green branches on the bud, blowing green grass on the ground, but also blowing the enthusiasm of kindergarten children, in this spring day, we ushered in the annual "3.12" Arbor Day. We advocate "adding a little green and a little more beautiful", so that children can actively "dialogue" with the natural environment and actively participate in the activities related to Arbor Day. Experience the pleasure of labor, feel the meaning of beautifying the environment, and inspire the emotion of loving nature. So we organize children to carry out tree planting, love trees, tree protection, and other related activities.

植樹(shù)節的意義

植樹(shù)節是為(wèi)了保護倡導人(rén)民種植樹(shù)木，鼓勵人(rén)民愛(ài)護樹(shù)木，提醒人(rén)民重視(shì)樹(shù)木。樹(shù)木對于人(rén)類的生(shēng)存，對于地球的生(shēng)态環境，都是起着非常重要的作(zuò)用。

印度加爾各答(dá)農業大(dà)學德斯教授對一棵樹(shù)的生(shēng)态價值進行(xíng)計(jì)算(suàn)：一棵50年樹(shù)齡的樹(shù)，累計(jì)計(jì)算(suàn)，産生(shēng)氧氣的價值約31,200美元；吸收有(yǒu)害氣體(tǐ)、防止大(dà)氣污染價值約62,500美元；增加土壤肥力價值約31,200美元；涵養水(shuǐ)源價值37,500美元；為(wèi)鳥類及其他動物提供繁衍場(chǎng)所價值31,250美元；産生(shēng)蛋白質價值2,500美元，總計(jì)創值約196,000美元 。

Arbor Day is to protect and advocate people to plant trees, encourage people to love trees, remind people to pay attention to trees. Trees play a very important role in the survival of human beings and the ecological environment of the earth.

The ecological value of a tree has been calculated by Professor Des of the Calcutta University of Agriculture in India: a 50-year old tree yields an accumulated value of about US $31,200 in oxygen; the value of absorbing harmful gases and preventing atmospheric pollution is about US $62,500; the value of increasing soil fertility is about US $31,200; and the value of conserving water is US $37,500; provides breeding grounds for birds and other animals valued at $31,250; produces protein valued at $2,500, for a total value of approximately $196,000.
