Currently, the application of nanotechnology is considered as a new direction to develop efficient, safe and sustainable agriculture. In Vietnam, nanotechnology has also been used very effectively in agriculture in recent years, for example in the production of crop protection products, seed treatment, veterinary medicines for livestock, aquaculture and other industries. Products for water treatment and the environment…

According to expert research, trace nanoparticles act as a biological stimulant. When a nanoscale trace element acts, the potential is awakened and the plant grows to another level. By spraying the leaves with trace amounts of nanoparticles, the leaves are absorbed and the plant is provided with the necessary nutrients for good growth and high yields.

Recently, the Ministry of Science and Technology of Quang Ninh Province has cooperated with the Research Institute of Agricultural and Rural Planning (Vietnam Union of Science and Technology Associations) and related units to carry out a research project on building construction. Model of using organic nanotechnology fertilizers for the production of rice, vegetables, fruit trees… in Quang Ninh province, including custard in Dong Trieu city.

There are currently about 1,600 Na households in Dong Trieu city, covering an area of ​​over 800 hectares (including Na Dai and Na Bo). The production area is concentrated in the municipalities of Viet Dan, An Sinh, Tan Viet, Binh Khe… with a production of over 6,500 tons of fruit per year. The harvest time is from the end of July to mid-August, the harvest time from the end of October to the end of November.

Mr. Nguyen Van Khoa (Tan Thanh Village, Viet Dan Township, Dong Trieu City) shared that his family currently owns 0.5 hectares of land where nano-mixed water is used to irrigate crops. After 3 months of using nanotechnology, the custard apple tree in the garden grows healthily, the leaves are darker than the non-irrigated area, which restricts plant diseases such as mycorrhizal fungus, yellowing of leaves and harmful insects such as aphids, red spiders and thrips. ..

It can be said that the use of nanotechnology in agriculture meets the requirements of organic farming, thereby creating high-quality agricultural products, contributing to the socio-economic development of the place, and contributing to a sustainable economy. Clean farming, save costs, increase productivity and quality of plants.

At present, the city of Dong Trieu continues to implement mechanisms and policies to support production in accordance with GAP, organic, certified organic and high-tech production; Supporting the association of production, consumption, preservation and processing of products. In the field of science and technology transfer, it is expected that the city will support 100% of the funding for education, training and consultancy, and technology transfer.

The goal is that by 2030, the entire city of Dong Trieu will have 1,150 ha of Na Na trees. The average yield is 15-25% higher than the current one, so the total net profit from the city’s custard apple tree is about 260 billion VND/year. At the same time, the municipality recommends that owners of custard apple orchards older than 20 years of age replace crops, change cultivars, and switch crops to increase profitability.

In Quang Ninh Province, there are now a number of models for the application of nanotechnology in agricultural production, which initially brought positive results, such as the trial production of rice variety J02 using biofertilizer technology. Nano in Phong Hai District (Quang Yen City); Application of nanopreparations in tea cultivation in Quang Phong township (Hai Ha district)… The use of nanotechnology in agricultural production contributes to improving the quality of agricultural products, the formation of environmentally friendly products and the construction of buildings. ecological and sustainable agriculture.
