HCM City: Hi-tech methods boost farm produce value
HCM City (VNA) - The production value per hectare of land in Ho Chi Minh City reached 450 million VND (19,736 USD) last year, an increase of 10.9 percent 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 Saigon 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 Saigon) 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 no antibiotics or banned chemicals were used
during the breeding period.
Trang Quoc Dung of the Nong Phat Company said the
technology had helped raise productivity and quality of the company’s honeydew
melons, which are grown in membrane houses and watered by drip irrigation
systems in Hoc Mon district.
The company plans to use hi-tech applications for
more vegetables such as asparagus this year, Dung said.
According to the city’s agriculture department,
hi-tech methods are being used on 390ha of vegetable, flower and fruit
cultivation.
The economic value from these kinds of vegetable
has been 1 billion VND to 1.4 billion VND per ha every year. Nearly 2 billion
VND is earned from each ha of orchids annually.
Speaking at a recent conference on agricultural
activities last year, Le Thanh Liem, vice chairman of the city People’s
Committee, said that such farms should be expanded into hi-tech agricultural
zones.
He said the city should provide low-interest loans
to encourage enterprises to invest in hi-tech agriculture. But many of them
complain that they have difficulty accessing low-interest loans due to lacking
of collaterals.
Moreover, companies must be certified to use
hi-tech agricultural techniques in order to apply for loans for hi-tech
agriculture purposes.
The Saigon Agriculture Biotech Corporation, for
example, applied for the certification in 2016 but has yet to receive it.
Liem said that the city has policies to encourage
enterprises and individuals to invest in this sector.
He instructed the city’s agriculture department to
work with the agriculture ministry and give guidance to enterprises on how they
could benefit from these policies and receive certification.-VNA
