Evaluation of Survival Rate of Licorice (Glycyrrhiza uralensis Fisch) in Semi-Arid Region by Statistical Analysis

Abstract

Authors have been working on greening experiment of precious medicinal plant licorice (Glycyrrhiza uralensis Fisch.) by using developed GSMs (Greening Soil Materials) in non-habitat area of Southern Mongolia to combat for progression of desertification. GSM is made of sand and compost that can be taken around targeting ground. It can be controlled moisture and nutrient retention capacity in shallow part of ground for growing plants healthily by fixing the mixing ratio of the materials. It can be made and set easily and affordably. In this paper, for clarifying key geo-environmental factors of GSM to survive seeds of licorice, principal component analysis, and for making estimation formula of survival of licorice, multiple regression analysis were conducted. 13 kinds of parameters important for growth of plant such as volumes per one seed of licorice, water contention, CaCO3-Ca, pH, EC, various water soluble, and exchangeable cations of GSM were used by these analysis.
