However, so far, there have not been assessment reports on the growth and development of these cultivation models. This study aims to assess the cultivation of D. indica in Than Uyen. The survey results showed that the total area of Son tra in Than Uyen reached 397.5 ha. However, only the seedling originating from Yen Bai province was used for afforestation over the years. When intercropping with Pinus massoniana and applying intensive silviculture techniques, the D. indica trees grow well, especially at a density of 400 - 600 trees/ha. With the good soil, thick, moist, rich in humus, the plants grow very well. In contrast, in the bad soil, thin, dry, the plants grow poorly, and are attacking by pests and diseases. Longhorn beetle, drying branches disease, fruit spot disease and fruit rot disease have been recorded as major pests and diseases in D. indica in Than Uyen. Therefore, it is necessary to develop this species in the direction of intensive silviculture and to continuing research on pest and disease management measures to sustainably cultivate D. indica in Than Uyen district, Lai Chau province
