A Detailed Guide to the Latest Cultivation Techniques and Methods for Dalbergia odorifera
Dalbergia odorifera is one of the traditional Chinese medicinal materials. It is a tree of the genus Dalbergia in the Fabaceae family, and its medicinal part is the dried heartwood of its trunk and roots. It is used to treat conditions such as abdominal pain and traumatic injuries. Dalbergia odorifera also has a certain ornamental value, and can also be used as household timber, or its Dalbergia odorifera oil can be extracted for use as a fixative. Many people do not know how to cultivate Dalbergia odorifera, so today the editor will give everyone a brief introduction to the cultivation techniques for Dalbergia odorifera.
1. Growing Environment
Dalbergia odorifera has relatively strict requirements for its growing environment, so this is one of the reasons why it is so rare. Generally speaking, the cultivation site for Dalbergia odorifera should preferably be mountain land and gentle slopes with moderately acidic or slightly acidic soil, good drainage, a sunny aspect, and brown or red loam. Next, the temperature at the cultivation site is best when it averages 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 for 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, removed after one day, and sown after the seeds are dried. This can promote the germination speed of the seeds, and generally seedlings will emerge in about half a month. For cutting propagation, the main trunk part of Dalbergia odorifera seedlings, or side branches, are used for cuttings, and generally new roots will grow in about one month.
3. Cultivation Management
⟦NL>Generally, when the seedlings grow to about 50 cm, we can transplant and establish them. The initial planting density is about 300 to 500 seedlings per mu, and the planting density should be reasonably planned according to the fertility of the soil. Under normal circumstances, the row spacing for 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, and 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, and later gradually cultivate the main trunk and branches of the saplings so that they form a crown, and the crown should be pruned to maintain reasonable permeability. During the growth process of Dalbergia odorifera, that is, in about the first four years, we should organically combine fertilization, intertillage, earthing up, weeding, and hole expansion, about 3 to 4 times each year. After the fifth year, we only need to carry out field operations once each year.
4. Pest and Disease Control
During the growth process, Dalbergia odorifera can also suffer from pests and diseases, such as black spot disease, anthracnose, Oncideres sp. longhorn beetles, and false geometrid moths. Black spot disease generally occurs around June and July each year and harms the entire Dalbergia odorifera tree, and we can use Bordeaux mixture for control. Anthracnose is a very common disease and is usually treated with Bordeaux mixture. The Oncideres sp. longhorn beetle generally begins to appear in February and continues until around April, causing serious damage to the young branches of Dalbergia odorifera, and trichlorfon can be used to poison and kill them. The false geometrid moth generally appears in early April and mainly harms the young branches of Dalbergia odorifera, and phosmet can be used for control.
