At same time, the leaf areacoefficient, dry matter accumulation and economic coefficient of compact type corn variety is bigger than loosely type corn variety.
Through practical experiments, this paper correct the aggregate surface-areacoefficient which is used to calculate asphalt membrane thickness in exiting specification.
