Researchers of the Institute of Forests of Economic Value under the Academy of Forestry proved that new species of sea buckthorn of high economic value can be planted in the northern areas of the country with a height of 700 metres above sea level and an average annual temperature of 0-7℃ and an average annual precipitation of less than 900 mm.

According to Kim Un Ho, section chief of the institute, it is advisable to plant a cutting of one-year-old branch, 5mm thick and 12-17cm long, with a rooting rate of 82%. When it is cultivated under the awnings, its rooting rate can be raised to over 83%.

It is better to plant saplings in spring when the survival rate is high, than in autumn.

The researchers proved that the new species can be planted not only in the highlands in Ryanggang Province but in cities and counties in North Hamgyong, South Hamgyong and Jagang provinces.

Their research findings about the features and composition of the newly-bred sea buckthorn varieties in the country’s northern highlands were highly appreciated in the 35th national sci-tech festival.
