What should I pay attention to when transplanting camphor trees?

1, planting

Planting is easy to survive before germination in early spring, and the planting soil should be deep and fertile, with organic matter content of 1% ~ 3% and good air permeability. Put the decomposed organic fertilizer on the bottom of into the pit, and then add 20 cm thick ripe soil to mix it fully to avoid burning the roots. If the weather is dry, fill the planting pit with water, and then plant it after the water seeps dry. Cinnamomum camphora is generally planted with soil balls. Cinnamomum camphora is not easy to take root after deep burial, so it should be planted shallowly. Usually, the rhizosphere line of the original seedling is flush with the ground or 1 cm to 2 cm higher.

2. Water and fertilizer management

Water for 5-7 days after transplanting. After Cinnamomum camphora survives, there is no need for frequent irrigation. Generally, after the soil is thawed, water is poured for the first time before germination. In May, if the weather is dry, you can water it for the second time to facilitate the growth and development of Cinnamomum camphora. Watering can be done according to the weather in rainy season. Cinnamomum camphora is drought-resistant and afraid of waterlogging, so pay attention to drainage in rainy days. Because the roots of Cinnamomum camphora breathe a lot, it is necessary to prevent the roots from rotting and dying because of excessive water and lack of oxygen in the soil. Fertilize in autumn and winter. At the periphery of the tree crown, apply the decomposed organic fertilizer once by ring fertilization or drilling holes, and then water it. Cinnamomum camphora has suspended animation and suspended animation. Some Cinnamomum camphora leaves can spread even if the root system is dead, and even germinate in the second and third years, but the leaves are small. When the nutrients in the tree are exhausted, leaves will not grow, which is a false phenomenon of Cinnamomum camphora. Some Cinnamomum camphora plants do not germinate in the first year, or even in the second year, but the bark is still bright green, and it is not until the third year that they begin to germinate and spread their leaves. This is a phenomenon of camphor tree suspended animation. So some people say: if you plant camphor trees, you will not be born for three years, and you will not die for three years.

3. Pruning, intertillage and pest control

Cinnamomum camphora does not need special pruning, but can be pruned before transplanting, and at the same time, it can cut off over-dense branches, pest branches, residual branches and dead branches. In the process of its growth, because of its slow growth, it is generally not pruned. In the process of maintenance, intertillage and weeding are needed in time to reduce weeds, which is beneficial to the growth of trees, improve the ventilation conditions of soil, promote the growth of roots and sprout new roots. There are few pests and diseases of Cinnamomum camphora. In the hot and dry years in summer, the seedlings born in that year or newly transplanted seedlings are easy to burn at the stem base, which makes bacteria invade and rot easily after rain. In summer, shade shed can be set up or Bordeaux mixture can be used for prevention and control. The main pest is grubs. Cinnamomum camphora is an excellent greening tree species with simple cultivation and extensive management. The management of Cinnamomum camphora after transplantation is very important, but the soil porosity and the ratio of root size to branch retention will also affect the survival of Cinnamomum camphora after transplantation.
