Osmanthus fragrans, also known as Osmanthus fragrans, is an evergreen tree of Oleaceae. There are many kinds, which can be divided into four seasons osmanthus fragrans, osmanthus fragrans, osmanthus fragrans and so on. Because of its fragrant flowers, it has certain resistance to harmful gases such as sulfur dioxide and hydrogen fluoride, and is widely cultivated in gardens, parks, factories and communities. However, due to the low lignification degree of Osmanthus fragrans root system and the long recovery time after transplanting, it is necessary to master certain management techniques to reduce unnecessary losses in order to grow successfully after transplanting. When will osmanthus trees be transplanted? How to manage after transplantation?

1, transplant time

Generally speaking, osmanthus trees can be transplanted in spring or autumn, but spring transplantation is the best. Because the temperature is suitable in spring, and the root water is not easy to lose when transplanting. Transplanting in autumn should be carried out in a place where the temperature gradually turns cold and there is sufficient water, usually after 10.

2. Selection and preparation of transplanted seedlings

Before transplanting, it is best to choose transplanted seedlings with good growth, strong branches, no pests and diseases and no new buds. Improve the success rate after transplantation. At the same time, the big osmanthus tree to be transplanted should be watered/kloc-0 times a week in advance to make its roots absorb enough water. This makes it easy to dig into balls, and the soil balls will not be scattered because the soil is too dry.

Step 3 raise seedlings

It is best to choose the right time when raising seedlings. Generally, it is best to raise seedlings early and late on cloudy days or sunny days, but don't raise seedlings in rainy days (because rainy days are easy to be infected with viruses). And it is best not to raise seedlings for more than two days. Raise seedlings with hoes and shovels. Generally, the diameter of soil balls should be 6 ~ 8 times of the diameter of plants, and it is better to dig a little bigger if conditions permit. Try to hurt the roots as little as possible and avoid pulling out the seedlings. The soil ball is tied firmly with straw rope or with food bag and rope.

Step 4 plant

Before planting, the seedling pit should be dug well to avoid the root being exposed to air for too long, which will lead to water loss. At the same time, after transplanting, the pre-dug tree pit should be filled with 10 ~ 15 cm original soil brought back by transporting osmanthus trees. In addition, because osmanthus trees are not flood-resistant, the planting depth of osmanthus trees is 10 ~ 15 cm higher than the original ground, so as to avoid water accumulation caused by rainy weather, excessive water in seedlings and poor root growth. In addition, all tree pits should be filled, cofferdam and watered. If the osmanthus tree to be transplanted is large, it should be pruned properly to reduce water evaporation and improve the survival rate of transplantation.

5, post-management

The key to planting osmanthus trees lies in water management, and water 1 time after 3-4 days. Big seedlings should also be supported by wood, so that the seedlings will fall or skew with the wind, which will affect the adhesion between roots and soil. If it is planted in autumn, it is best to wrap the trunk with straw to prevent cracking. If the weather is dry when planting, foliar water spraying or whole plant water spraying should be carried out.

To sum up, if you want to transplant osmanthus trees successfully, you must choose seedlings without pests and diseases and new shoots, and it is best to transplant them in spring or autumn to reduce the infection of pests and diseases. In addition, the transplanted osmanthus trees need to ensure adequate water and fertilizer, promote root growth and improve the survival rate of seedlings.
