Progress Made in Propagating Golden-leaf Cryptomeria

Pyongyang, May 19 (KCNA) -- Researchers of the Economic Forest Institute under the Academy of Forest Science in the DPRK have made progress in widely propagating the golden-leaf cryptomeria.

The golden-leaf cryptomeria is a high tree with golden yellow leafs. It grows fast and is highly resistant to cold, heat and blight and insects. If it is planted at sidewalk, park and pleasure grounds, it can create a beautiful landscape.

Researchers of the institute deepened the study of this tree's biological characteristics to provide a technical guarantee for mass-producing its saplings in a way of nutrient propagation. They also pushed ahead with the research to find ways for increasing the effectiveness of nutrient propagation to the maximum and verifying biological characteristics according to different indices, while examining the growth of stock saplings according to sunshine, temperature and humidity every day.

They thus opened up a prospect for putting the production of saplings on an intensive and industrial basis and shortening the production cycle.

The institute is now intensifying the research to settle the problems arising in the cultivation of saplings under different conditions and environment in a sci-tech way. -0-
