Poplar transplanting technology

First, emergence: It is advisable to sow in early March to before germination in spring. Fill the trees with enough water within one week before emergence. When the seedlings emerge, the root width can be 5 ~ 8 times of the ground diameter of the seedlings, and bare roots can be planted without soil balls. Saw off the root with a saw or a sharp axe to prevent cracking, and then smooth the wound with a knife to facilitate rooting. After the trees are planed out, according to the requirements of greening design, 3 ~ 4 main branches are reserved at 2 ~ 2.5m on the trunk, and the main branches are truncated by 50 ~ 80cm (the height of the main branches is 4 ~ 5m, and the main branches on the second floor are trimmed). Wrap the trunk with plastic film or straw rope. Apply paint or alum to the wound to prevent water loss. Avoid knocking off the bark and splitting the main branches during transportation.

2. Digging: The pit should be large enough to accommodate tree roots, and the depth is higher than the original soil trace 10- 15cm.

3. Planting: Plant the seedlings as soon as they arrive. Before planting, apply rooting powder No.2 solution on the root incision to promote rooting. When planting, put the seedlings in the into the pit for righting, and tamp them along the root gap with wooden sticks when filling the soil until they are flush with the ground.

4. Watering: After planting, the soil weir should be enclosed immediately and flooded once. After irrigation, it should be thoroughly checked and fixed with brackets. Fill it out again in two weeks, and then moisturize the mound. In the future, you can open piers and water them according to the soil drought.
