Kangwon Province has studied and completed the way of optimizing the growth conditions, thus ensuring successful cultivation of tree saplings while saving labor and efforts more than before.

North Phyongan Province has provided a foundation for keeping the production of tree saplings going on a higher level even in winter season by preparing hundreds of tons of good-quality organic manures to increase the fertility of sapling fields.

Nampho City has finished the work of seeding and planting cuttings and is meticulously manuring and tending the tree saplings for germination and nutrition.

And also it has put the production of tree saplings on a higher scientific basis by applying real-time salt-measuring system to the production and using general water analyzer.
