1. Generally, the process of planting trees includes six steps: digging, filling, planting, watering, covering and fixing. However, it is only necessary to straighten the seedlings in the process of planting trees, and the operation is relatively simple.
 2. Pit excavation: at this time, the pit shall be excavated according to the size of the tree, generally 50 cm. The soil for pit excavation shall be the mellow soil on the top and the loess on the bottom.
 3. Filling: Generally, a little mellow soil should be backfilled to facilitate the growth of trees.
 4. Tree planting: when planting trees, ensure that the seedlings are upright. When filling soil, step around the trees and fill another circle of soil. The soil should be as lower as possible than the ground, so that it is convenient for future maintenance and watering.
 5. Watering: If possible, water the well as much as possible, because the purified water lacks minerals.
 6. Covering soil: after watering, cover it with a layer of soil, which can better keep water and grow better.
 7. Fixation: because the saplings are relatively small, they are easy to be blown down when it is windy or rainy. At this time, when conditions permit, you can insert sticks or bamboo poles into the trees to fix the saplings, so they are not easy to be blown down by strong winds.
