title: [Agronomic standardization of Gynostemma pentaphyllum (Thunb.) Makino].
abstract: In this paper, the simulation models for 3 main agronomic measures, plants/mu, cuttage date and supplement of nitrogen that affect the yield and economic effect of Genostemma:pentaphyllum, are analyzed by the quadratic orthogonal rotative regression design. As a result of the analysis optimal agronomic combination models are suggested.
