    When school was about to leave in the afternoon, the children lined up in the corridor. At this time, some uncles used dump trucks to transport carts of black soil, and then poured it on the roots of the big trees.  The class looked at the scene in front of them, very puzzled

    "Mr. Luo, what are those black soils used for?"

    "Is there any difference between black soil and loess?"

    I explained to them that the black soil is rich in nutrients, and the big tree grows so tall now because its roots are deeply rooted in the soil, and the roots have been quietly absorbing nutrients in places we cannot see, and now if  If it wants to continue to grow upward, it needs to continue to absorb more nutrients.

    Let me also explain to everyone that every kind of soil is different, some are loess, some are black soil, and the nutrients contained in different colors of soil are different.  However, different plants are suitable for different soils, and sometimes the soils can be neutralized Plants are very adaptable, and plants may need different nutrients in different periods, just like us humans, we learn in different periods  Different knowledge masters different skills, so as to grow smoothly

    After the explanation, everyone seems to understand.  And I suddenly remembered that during the recess this morning, a little boy in the class asked me if I noticed any changes around me.  At that time I shook my head, and finally the little boy pointed to the big tree outside the window and said with a smug smile: "Mr.  The little lantern is hiding in the leaves"

    Nutrients allow the tree to grow, bloom, and bear fruit.  This tree is the trees outside the window, and it is the lovely you in the classroom.  (Remember the site URL: www.hlnovel.com
