The Pyongyang University of Architecture studied and introduced a new tree-vitalizer effective in enhancing tree's resistance to diseases and survival rate and making leaves remain green longer.
Researchers of the university have developed the effective tree-vitalizer by making a rational use of various macro- and micro-elements and growth-controlling materials extracted from natural resources rich in the country.
The vitalizer, developed totally with domestic raw materials and technology, was applied to cultivation of trees in many places to ensure the survival rate of saplings on a high level.
According to experience gained by the units that used the vitalizer, it can boost the survival rate of trees, help lengthen tree's green period and contribute to afforestation and increasing fruit production.
