Pyongyang, March 5 (KCNA) — The Central Tree Nursery under the Ministry of Land and Environment Protection in the DPRK has made achievements in sapling production.
The tree nursery ensures the healthy growth of saplings with efficacious slow-acting fertilizer, saving a large amount of fertilizer.
It also settled sci-tech problems in watering all nursery gardens with a pump and thus reduced the cost of sapling production.
And it established the new methods of exterminating harmful insects with biological pesticide, producing substrates and shortening the date of their fermentation, all of which are of great significance in putting the sapling production on a scientific, industrial and intensive basis.
On the basis of achievements made in the research into seasonless tree planting, it generalizes throughout the country tree planting and cultivation methods proper to the climatic features of the country.
According to chief engineer Pak Tong Rim, the nursery has produced tens of millions of good species of saplings every year and acclimatized over 70 kinds of trees.
