Transplanting Technique of Cinnamomum chinense
Cinnamomum camphora tree is an important timber and special economic tree species in the subtropics, with majestic posture, bright spring leaves, branches and leaves, shade everywhere, smoking, dust retention, water conservation, soil fixation, sand prevention and beautification of the environment. It is the most common in the south. It is widely used as shade trees, street trees, and can also be used to create scenic forests and shelterbelts. Let's take a look at camphor tree transplanting technology.
Camphor tree transplanting time
The suitable transplanting time of camphor trees is one of the key factors to improve the survival rate. Usually, the best transplanting time of camphor trees is before sprouting in mid-early March, too early or too late is not good, too early is easy to be frozen, too late is not suitable to transplant whole beads, so it can not meet the requirements of camphor growth.
Transplanting technique of Cinnamomum camphora
The main results are as follows: 1. Truncated tree transplanting method is usually suitable for camphor trees with a DBH of more than 10 cm. Because it grows in situ all the year round, the root system distributes widely and deeply, and the crown is large, so it is not easy to transplant. The truncation method can control the branch height, and it is convenient for hoisting and transportation. it can also reduce the consumption of water and nutrients in leaves, which is beneficial to improve the survival rate. However, the tree shape is not beautiful in a short time, and the greening effect is poor, so it generally takes more than 2 years to form the crown width.
2. Root-cutting and crown-shrinking method: the root-cutting and crown-shrinking method is to cut the root and crown of the camphor tree that is planned to be transplanted in situ. Keep the basic tree-shaped skeleton when pruning, cut the root to 5 times the diameter of the trunk, cut off the thick root, spray 0.1% naphthalene acetic acid solution on the root, and then cover the soil. Transplant according to the need after 2 years. The advantages are that the survival rate of transplanting is high, the trees recover and grow quickly, and the greening effect is better. The disadvantage is that the cycle is long and the input cost is high.
3. The method of transplanting with crown: the method of transplanting with crown is basically to keep the original crown for transplanting, often for the immediate landscape and specific requirements. It is technically difficult to transplant, especially for trees with a DBH of more than 15 cm. Before digging, the crown should be re-cut, the weak branches should be removed, 50% of the leaves should be retained, and the transpiration loss of water and nutrients should be reduced. The diameter of the soil ball is more than 8 times the diameter of the trunk, and then the soil ball should be bandaged and transplanted.
Transplanting Management of Cinnamomum camphora
1. 0.1% naphthalene acetic acid solution or rooting powder was sprayed on the roots before transplantation to promote the growth of new roots.
2, camphor tree transplanting wound repair period to prevent decay, can use 0.1% naphthalene acetic acid solution and lanolin ester mixture to smear the wound.
3. The rotten organic fertilizer was applied at the bottom of the transplanting hole, and the loose soil was replaced in the hole to supplement nutrients.
4. When transplanting, it is better to be shallow than deep. According to the situation of groundwater level, it is appropriate to use the soil ball to expose the surface of the earth, and it is suitable for the soil ball to be exposed to the surface.
5. Apply fine soil to make the soil ball firm, pour heavy water, and then cover the surface of the root with film to prevent the evaporation of water or excessive infiltration of water into the root, resulting in rotten root.
6. after the camphor tree is transplanted, the camphor tree is dried with grass rope, then wet, thoroughly, and then dried with thin film, which can not only keep the trunk moist, but also prevent the trunk from evaporating and the bark from being burned by the sun. But do not burn the bark caused by the rot of the grass rope.
7. For crowned trees, spray devices can be installed at the top of the crown, and foliar spraying can be carried out on sunny days.
8. For the big trees transplanting with crown, considering the excessive evaporation of water on the leaf surface, build a shading shed to reduce the light intensity, so as to reduce the evaporation of water.
9. After the new leaves germinated and leathered, 0.1% urea solution was sprayed on the leaves to supplement the lack of nutrients in the roots and be beneficial to the growth of new leaves. But don't spray it in autumn.
10. after the new branches germinate, prune the weak branches, retain the strong branches, cultivate the new branches, and erase the adventitious buds germinated on the trunk immediately.
