title: [Orthogonal test for the best conditions of treating licorice seeds with sulphuric acid].
abstract: Adopting the method of orthogonal test and using the orthogonal table of L25(5(6)), this paper has made a test of the influential factors in treating the licorice seeds with sulphuric acid. The result shows that the best treating conditions are as follows: H2SO4 concentration over 80%. H2SO4 amount 10-20 ml/kg. Treating temperature 10-25 degrees C. Treating time 2 hours.
