Oranges changed lives.

- With a spirit of daring to think, daring to act, and a determination to get rich on his homeland, Mr. Duong Doan Hung, born in 1970, from Lan Da village, Tan Tri commune, has successfully developed a model of grafting Canh sweet oranges onto pomelo rootstock, bringing in high income.

Mr. Hung harvests Canh sweet oranges.

During our work trip to Tan Tri commune in late December 2025, we had the opportunity to visit the Canh sweet orange cultivation model of Mr. Hung's family in Lan Da village. This is also one of the typical economic models in the commune.

Sharing his journey of self-improvement, Mr. Hung confided: "I was born into a farming family. Previously, our family's economy depended mainly on small-scale agricultural production, so life was quite difficult. To provide a better life for my family, I was always thinking about how to get rich. In 2015, realizing that the local climate and soil were suitable for growing citrus fruits, I invested in planting 500 pomelo trees. However, after about three years of planting and harvesting, the economic return from the pomelo trees was not high. I continued to look for another path."

In 2019, Mr. Hung experimented with grafting Canh sweet oranges onto 100 pomelo trees. At that time, he was the first person in the commune to implement the model and mainly learned the technique on his own. Initially, due to lack of experience, the survival rate of the grafted Canh sweet orange trees on pomelo rootstock was low, and their growth and development were poor.

To gain more knowledge and skills, he proactively participated in training courses on the transfer of scientific and technical knowledge in planting and caring for fruit trees organized by the commune government; at the same time, he visited and learned from the practical experiences of some effective models.

Mr. Hung said: "Choosing the right grapefruit rootstock for grafting is a very important step, determining the survival rate of the tree. Therefore, growers must choose healthy, well-growing rootstocks. The most suitable time for grafting is around February to March according to the lunar calendar. When grafting, the process must be decisive, ensuring the sap at the graft union does not dry out. The graft union must be wrapped tightly in plastic, and the side branches of the rootstock should be regularly pruned to ensure the grafted shoot receives sufficient nutrients for development."

Thanks to his diligence and hard work, he acquired the basic knowledge to apply to his family's practical model and achieved initial success. Accordingly, in 2021, 100 grafted pomelo trees with Canh sweet oranges yielded about 2 tons of fruit, bringing in nearly 100 million VND in income. With high economic efficiency, he continued to graft Canh sweet oranges onto the remaining 300 pomelo trees and planted new Canh sweet orange trees every year. To date, his family has over 1,200 Canh sweet orange trees. On average, his family harvests about 15 tons of oranges each year, with selling prices ranging from 35,000 to 55,000 VND/kg, bringing in nearly 700 million VND in income after deducting expenses. Currently entering the Canh sweet orange harvest season, his family expects to harvest about 30 tons of fruit this year, double that of last year.

It is known that, in addition to orange trees, his family currently has over 200 green pomelo trees. On average, his family harvests over 5,000 fruits annually, selling them at 50,000 – 60,000 VND per fruit, bringing in an income of 200 million VND after deducting expenses. From this citrus fruit farming model, his family earns a total income of nearly 900 million VND per year and creates seasonal jobs for 20 local laborers.

Ms. Tran Thi Thinh, Vice Chairwoman of the Vietnam Fatherland Front Committee of Tan Tri commune and Chairwoman of the Tan Tri Commune Farmers' Association, said: Mr. Hung is a pioneer in grafting Canh sweet oranges onto pomelo rootstock, which has yielded high economic efficiency. The successful implementation of this model has opened up a new direction for economic development for people in the commune.

With a thirst for knowledge and a strong will to overcome difficulties, Mr. Duong Doan Hung has successfully developed a high-income economic model. He deserves to be a role model for the people in the commune to learn from and emulate.
