Sedum kamtschaticum is a vegetable of high medicinal value, whose content of vitamins C and B12, iron and calcium are three to ten times higher than other vegetables.
Regular intake of the vegetable helps prevent arteriosclerosis and cerebral thrombosis, protect the liver and cure heart and nervous system disorders.
The Pyongyang Vegetable Science Institute of the Academy of Agricultural Science brought to light technological problems arising in the cuttage and other processes of growing the vegetable, thereby completing the method of growing it in great numbers under normal conditions.
According to researcher Sin Jun Myong, the acclimatized Sedum kamtschaticum can easily be grown anywhere as it is not so sensitive to environment and can be harvested three or four times a year.
“The blue insam” is a vegetable species containing a proper amount of protein, fat, carbohydrates and coarse fibre and has rich content of lignin, minerals and vitamins.
The researchers established a scientific method of growing the “blue insam” all the year round in greenhouses whose temperature is over 15 degrees centigrade, thereby ensuring a per-hectare yield of 20-25 tons.
Edible sponge cucumber is another functional vegetable that has plenty of nutrients, and it has two or three times more protein than that of pumpkin and cucumber.
Its unripe fruits promote metabolism in the human body and are effective in preventing heatstroke, purifying blood, neutralizing poison, reducing inflammation and controlling blood pressure.
The researchers also solved technological problems for growing the edible sponge cucumber outdoors or in greenhouses according to localities and completed the technical guidelines for its growing.
According to the guidelines, its per-hectare yield is some 60 tons.
