The Mekong and south-eastern regions have great potential to grow medicinal and edible mushrooms all year, according to the National Agricultural Extension Centre.
Besides, farmers in the regions basically know all about mushroom breeding techniques and cultivation of straw, fungus, button and oyster mushrooms while the demand for the fungus has been growing gradually.
Trần Văn Khởi, acting director of the centre, told a forum on hi-tech mushroom production held in An Giang Province last week that it has developed in southern provinces, generating good incomes for farmers.
They grow 16 kinds of mushrooms with an annual output of 250,000 tonnes, earning US$25-30 million from exports.
Oyster mushrooms fetch $2,600 per tonne, which is higher than from other agricultural products, besides which mushroom cultivation helps use up a large quantity of agricultural residues and creates employment, Khởi said.
The Mekong and south-eastern regions have farming residues like straw that could be used to grow mushrooms, but production of the fungi is well below potential because of poor use of technology.
Lê Quang Thái of the Nacentech Technology and Business Incubator Centre, said the diversity of edible and medicinal mushrooms in Việt Nam is still poor.
The use of technology, such as environmental sensors and automation, has not been considered, he said.
The biggest problem is in the area of post-harvest preservation technologies since mushrooms are mainly consumed fresh or dried and salted for export within 24 hours after harvest, he said.
Mushrooms are mostly still cultivated manually in traditional ways since farmers do not know they can improve productivity with technology, he said.
They should use technologies more to increase production of high-quality mushrooms, he added. — LV
