Abstract

In recent years, the land deterioration by decreasing licorice (Glycyrrhiza uralensis Fisch.) becomes one of the most serious problems in Mongolia. Authors try to propose the high value-added greening by establishing a sustainable planting technique by utilizing licorice. As the first step, the geo-environmental and climate survey was conducted to grasp the environment in licorice habitat area. Based on the results of the preceding survey, a method of greening using cylindrical Greening Soil Materials (GSM) were proposed and planting experiments were conducted in Mongolian arid land. Based on the results of field survey and planting experiments, following conclusions could be obtained. 1) There was the great difference between habitat area and non-habitat area for the amount of water in the ground. Both of surface layers were dry, however habitat area had relatively higher water content (5-20%) than the that of non-habitat area (1-3%) at the points deeper than 20 cm from surface. 2) Covering ground surface by vinyl mulching sheet could keep water content 1.1 times to 2 times or more and raise the survival rate of licorice. 3) The condition with mature and compost available in survey area could retain 3 times amount of water than that of only sand condition. 4) The bigger GSM could keep much more water and lead to high survival rate. 5) In case the water content could be kept 8% in the soil, 80% of licorice could survive and grow.
