When is Arbor Day 2020? How do you plant saplings?

Arbor Day is a festival to promote the protection of trees and organize the masses to actively plant trees and afforestation. On Arbor Day's day, tree planting activities are organized in many places, so when is Arbor Day in 2020? How to plant saplings?

When will Arbor Day be in 2020?

Arbor Day in 2020 is Thursday, March 12th, and the 19th day of February of the lunar calendar. Arbor Day is to protect and encourage people to plant trees, encourage people to take care of trees, and remind people to attach importance to trees. Trees play a very important role in the survival of human beings and the ecological environment of the earth.

Second, how to plant saplings?

1. Remove the soil ball packaging: in order to prevent the soil ball from loosening, the grass rope or non-woven fabric will generally be wound around the soil ball, but when the trees are planted, the winding packaging must be removed in time. For example, if the winding grass rope is not removed after late watering, the grass rope rotts, ferments and heats or burns the new capillary roots, which is not conducive to the survival of the tree.

2. Tree hole treatment: tree hole is an important environment for newly transplanted trees to take root. The soil environment of tree hole determines the speed of rooting and the rate of tree survival. Principles of tree burrow treatment:

The width of ① tree hole is about 20 cm wider than that of soil ball, and the height of soil ball is about 10 cm in depth.

② cleans up stones and other sundries in the tree hole.

③ soil is too poor to add appropriate fertilizer to the backfill.

If the soil is clay, ④ can participate in a certain proportion of coarse gravel in the original soil to facilitate soil permeability.

3. Watering trees after planting: watering trees after planting is one of the important measures for conservation. trees generally need to be watered three times after planting, once within 24 hours after backfilling, the second time after 7 days, the third time after January, and according to the principle of "no dry, no watering, watering thoroughly".

4. tree planting depth: the tree planting depth is generally 5-8 cm covered with soil, and the overlying soil can easily lead to poor soil permeability, resulting in low survival rate in the later stage of the tree, or relatively small leaves.

5. Chemical treatment: for difficult rooting tree species, in the process of watering and fixing root water after planting, some rooting promoting agents can be added to facilitate root germination as soon as possible.
