Green plants are known as natural dust collectors. There are many tiny hairs and mucus on the leaves, which can absorb carbon, sulfur, bacteria, viruses and other harmful substances in the smoke. Therefore, more trees should be planted.

Every country has its own Arbor Day.

Five steps to planting a tree.

1. Dig a hole.

When digging holes for small trees, neither too deep nor too shallow. According to the size of the sapling, determine the size of the pit to ensure that the root can be accommodated in the pit. When digging a hole, separate the top soil from the bottom soil for emergencies.

2. Plant trees.

When planting a tree, make sure the sapling is upright, hold the lower half of the trunk in your hand, place the sapling in the center of the pit, try to keep the trunk vertical, and make sure that the depth of the trunk is the same as its nursery.

When planting saplings, care should be taken to protect the roots of root saplings.

3. Fill with soil.

Use a shovel to evenly cover the soil around the sapling, about a half hole high at a time. One holds the seedlings and the other fills the tree holes with soil.

Then step on it with your foot. Sprinkle more soil around the trunk, or a large hole will appear next time you water.

4. Water.

Watering the tree is a very critical step, because when the tree is removed from the nursery, many roots are damaged, making it difficult to absorb water. Watering is primarily used to stabilize the soil, and filled soil can be irrigated as thoroughly as possible.

5. Cover the soil.

After watering, cover the ground with a layer of soil to make the soil wetter and grow better. If conditions permit, it is best to cover the tree with a layer of leaves or something like grass, which reduces humidity and prevents weeds from growing.

Let's take a look at the significance of parent-child tree planting activities.

1. Planting trees can reduce noise, beautify the environment, maintain ecological balance and create a beautiful home.

2. Cultivate children's love for nature and understand the meaning of "Arbor Day".

3. Enhance children's sense of ownership, strengthen teamwork spirit, strengthen classmate relationship and parent-child relationship.
