How to Plant Dalbergia odorifera? A Detailed Explanation of Cultivation Techniques
Dalbergia odorifera is a type of traditional Chinese medicinal material. It is a tree in the Fabaceae family, Dalbergia genus, and its medicinal part is the dried heartwood of the trunk and roots. It is used to treat conditions such as abdominal pain and traumatic injuries. Dalbergia odorifera also has certain ornamental value, and can also be used as household timber, or to extract Dalbergia odorifera oil for use as a fixative. Many people do not know how to plant Dalbergia odorifera, so today the editor will briefly introduce the cultivation techniques of Dalbergia odorifera.
1. Planting Environment
Dalbergia odorifera has relatively strict requirements for the planting environment, which is one of the reasons why it is so rare. Generally speaking, the planting site for Dalbergia odorifera should be selected in mountainous areas and gentle slopes with moderately acidic or slightly acidic soil, good drainage, sunny exposure, and brown or red loam soil. Secondly, the temperature of the planting site is best at an average of between 23 and 25 degrees, and the most suitable temperature for the growth of Dalbergia odorifera is between 20 and 25 degrees.
2. Propagation Methods
The propagation methods of Dalbergia odorifera are generally seed propagation and cutting propagation. For seed propagation, we generally sow in February and March each year. Before sowing, the seeds should be soaked in hot water at a temperature of about 60 degrees, taken out after one day, and sown after the seeds are dried. This can promote the germination speed of the seeds, and generally seedlings can emerge in about half a month. Cutting propagation uses the main trunk part or side branches of Dalbergia odorifera seedlings for cuttings, and new roots can generally grow in about one month.
3. Cultivation Management
Generally, when the seedlings grow to about 50 cm, we can transplant and establish them. The initial planting density is about 300 to 500 saplings per mu, and the planting density should be reasonably planned according to the fertility of the soil. Under normal circumstances, the row spacing of each plant is about 2 m, and the plant spacing is 1 m or 1.5 m. After establishment, we need to water once in the morning and once in the evening every day until the seedlings grow new roots. During this period, we must continuously fill in missing seedlings. During the growth process of the saplings, we should pay attention to pruning the tree shape to promote the growth of the saplings. Later, gradually cultivate the main branches of the saplings so that they form a crown, and prune the crown to maintain reasonable permeability. During the growth process of Dalbergia odorifera, that is, about the first four years, we should organically combine fertilization, intertillage, earthing up, weeding, and hole expansion, about three to four times each year. After the fifth year, we only need to carry out field operations once a year.
4. Pest and Disease Control
During the growth process, Dalbergia odorifera will also suffer from pests and diseases, such as black spot disease, anthracnose, longhorn beetle, and false looper. Black spot disease generally occurs around June and July each year and harms the entire Dalbergia odorifera tree. We can use Bordeaux mixture for control. Anthracnose is a very common disease, and Bordeaux mixture is usually used for treatment. The longhorn beetle generally begins to appear in February and continues until around April, causing serious harm to the young branches of Dalbergia odorifera. Trichlorfon can be used for poisoning and killing them. The false looper generally appears in early April and mainly harms the young branches of Dalbergia odorifera. Phosmet can be used for control.
