The Ryongsong District Forestry Management Station increases sapling production, relying on its own material and technical foundations such as parent nursery over several hectares of land and a plastic panel greenhouse.
Seed treatment, germinating and sowing are scientifically conducted according to a well-arranged production system.
The station has developed rooting promoter, general plant energizer and fertilizer made through indigenous microorganism-based fermentation so as to promote the growth of saplings and increase the rate of their survival.
These ensure the double cultivation of saplings in the greenhouse.
In particular, the energizer makes the leaves of the young trees healthy and glossy as it gives them a rich amount of nitrogen, phosphor, potassium and other nutritive elements.
Efforts are also being made to fully automate the management of nurseries.
Besides, power-free pumping machines, comprehensive sowing machine and other equipment are being produced or introduced.
Meanwhile, the station runs a sci-tech learning space to give its employees rich knowledge for building and protecting forests.
Jo Kwang Ryol in charge of the dissemination of sci-tech knowledge is called “Our Teacher” by forest rangers and nursery workers as his lecture on manuring and cultivation of saplings is easy to understand.
In the parent and branch nurseries the employees grow good species of young trees.
