2. Cedar is a shallow-rooted tree, and its lateral roots are mostly in the depth of 40-60cm in the soil. It is a fast-growing tree with an average annual height of 50-80cm, depending on the habitat and management conditions.
3. The transplanting period of cedar should be from April to May, and big trees are often used in gardens. Soil balls should be used for transplanting, and the support must be erected after planting to prevent it from being blown by the wind. Cedar grows rapidly, in the prime of life, and the central main branch is soft in texture, often bent and drooping, and is most vulnerable to wind damage, so it should be tied straight with thin bamboo poles in time. Keep the big branches and twigs under the cedar crown, so that they can be neat, beautiful and close to the ground naturally, and the lower branches must not be cut off, otherwise it will be self-defeating from the perspective of garden viewing.
4. Water thoroughly for the first time, after the scaffolding is finished. Water it for the second time after three days and for the third time after ten days. In order to ensure the survival rate, on the fourth day of planting, the roots were irrigated with 100ppmABT rooting powder No.3. After watering for three times, the holes can be sealed, and the tree holes can be covered with plastic film and set with a certain drainage slope to prevent the roots from accumulating water due to spraying during later maintenance. Plastic film can be covered for a long time to prevent cold and water evaporation. Then prune the branchlets. During the construction, Qin Ying will prune them for many times, and cooperate with seedling shaping and thinning treatment. Firstly, the diseased branches, overlapping branches, inner branches and individual big branches that affect the tree shape are removed. And don't trim and shape at one time to avoid trimming errors. After pruning, apply paraffin wax or antirust paint to the wound in time to prevent the wound from rotting in water, so as to ensure the water and air humidity required by the crown.
5, in the process of hoisting, seedlings should be sprayed with sprinkler immediately after planting. If a rope is used to tie the trunk, when the mucous membrane inside the bark is still wet, nail the fallen bark in place with a small nail with a length of 1 cm, evenly smear yellow mud on the wound, wrap it tightly with a straw rope, and then wrap it tightly with a thick plastic film to keep it wet. And always pay attention to loosening the soil and weeding. In the second year, the stent was taken out and entered normal management.
6. The survival rate of transplanting is high. After survival, apply organic fertilizer in autumn to promote its rooting, and topdressing can be done 2-3 times in the growth period. When the top of cedar is destroyed, we can choose the strong lateral branches near the top growth point, straighten them and tie them with bamboo poles, and appropriately subtract the lateral branches around the straightened branches to increase the top advantage. After 2-3 years, the crown can be repaired and the bamboo pole removed.
