Mr. Nguyen Van Ro grew up in a poor family, only finishing the third grade of the village school, he decided to study mechanical engineering to support himself and his family. With his diligence, hard work, and perseverance, he quickly mastered welding, turning, and repairing engines, then opened a local mechanical repair shop.

He recalled that in 2016, at this time, farmers had the need to plow and renovate shrimp ponds to improve the environment, regenerate natural food sources to help shrimp grow, and limit risks due to the impact of climate change and extreme weather. However, the traditional single-blade plow for agricultural production weighed more than 500 kg and could not operate on muddy aquaculture land. He converted the gasoline engine to reduce weight, combined with redesigning the wheel with a diameter of 60 cm and a length of 1.2 m, and put a plastic drum inside to prevent sinking. Thus, the improved plow and renovate shrimp ponds was born, lighter than the original by about 100 kg and effective in renovating shrimp ponds.

But because the length of the 2 cage wheels is up to nearly 2.5 m, combined with the width of the traditional tiller frame is quite large, making the improved tiller cumbersome, difficult to move, not suitable for small-scale, fragmented farming conditions and lack of concentration. So Mr. Ro continued to improve the tiller according to the criteria of being compact, with the lowest cost, so that farmers have the conditions to invest in order to promote mechanization in the shrimp pond renovation stage. After a long time of research, he chose a mini tiller to improve the tiller, using a used Japanese gasoline engine to reduce costs, reducing the width of the cage wheels to 40 cm, combining hanging 3 plastic cans inside to prevent sinking, reducing the weight of the improved tiller to less than 100 kg, operating effectively on all shrimp pond terrains. This product of his won third prize at the 15th National Technical Innovation Contest, 2018-2019.

In recent years, the model of rice production on shrimp farming land has been widely replicated by farmers in the district, but most of the shrimp land is not flat, and during the process of improving saline soil, it will stagnate in low-lying areas, which is not favorable for rice to grow immediately after sowing, and even causes damage due to saline poisoning.

According to statistics from the professional sector, in the 2023 crop, farmers in the district planted rice-shrimp on an area of ​​nearly 1,000 hectares, in the communes of Thanh Phu, Phu Hung, Hung My and Hoa My. By the 2024 crop, the planting area was expanded to 1,500 hectares and it is forecasted that in the 2025 crop, the rice-shrimp planting area will increase to 2,000 hectares.

In response to the need to renovate shrimp fields to grow rice, inventor Nguyen Van Ro continued to add a 2-blade plow attached to the above-mentioned super-lightweight improved machine. There is a new function of making drainage ditches for rice-shrimp fields, the sharp tip of the plow blade is installed facing forward, when the super-lightweight plow moves forward, the plowed soil is flipped to both sides to create a drainage ditch about 40 cm wide, depending on the actual conditions of the rice-shrimp field, farmers arrange the number of drainage ditches accordingly. At the same time, Mr. Ro also uses 2 boat-shaped buoys in super-intensive shrimp farming, connected behind the plow so that he can stand or sit on them to control the plow as desired, without having to walk behind each time the machine is put into operation.

During his lifetime, President Ho Chi Minh explained that the word “can” means diligence, hard work, effort, and perseverance in work and achieving results; if people know how to be diligent and industrious, they can do any job, no matter how difficult it is. Learning from Uncle Ho the word “can” to apply in life, Mr. Nguyen Van Ro became a mechanical inventor with a multi-functional improved machine, meeting the needs of agricultural production and aquaculture for farmers in and outside the district. He is considered a typical example in studying and following Ho Chi Minh's ideology, morality, and style./.
