Hi-tech methods raise production value of farm produce: HCM City

VietNamNet Bridge – The production value per hectare of land in HCM City reached VND450 million (US$19,736) last year, an increase of 10.9 per cent compared to 2016, largely due to hi-tech methods, according to the city’s Department of Agriculture and Rural Development. The growth in the city’s total agricultural production value last year was 2.2 times higher than the country’s average figure. The Sai Gon Agriculture Biotech Corporation is one of many hi-tech companies that have seen increased production value. Nguyen Hoai Nam, the company’s director, told the Sai gon giai phong (Liberated Sai Gon) that the company had applied biofloc technology to shrimp farming in the outlying district of Can Gio since 2013. Biofloc is waste water treatment system developed to mitigate disease in water in aquaculture facilities and farms. Before breeding, water in the system is filtered and treated, and microorganisms are grown to maintain water quality by the uptake of nitrogen compounds. Shrimp grow for 30 to 60 days and then are cultured in ponds in a closed system. Micro nanobubble oxygen generators, which are a new generation of efficient, energy-saving water treatment technology, are used in shrimp farms. The generators help provide a standard volume of oxygen for shrimp, which helps it breed successfully, Nam said. Hi-tech applications in shrimp farming have helped produce profits since 2016, Nam said, adding that nearly 50 tonnes of shrimp have been harvested per hectare per crop. The company’s foreign clients took test samples before harvest, which showed that… [Read full story]
