摘　　要：杉木种子的品质与球果脱粒方式有密切的关系,采用烘干和半晒半烘法较露天翻晒法所得种子发芽率、出籽率更高,存在显著差异,但烘干投入成本也高,技术难度大。半晒半烘法所得的种子其出籽率和发芽率与烘干所得的种子差异不显著,却能较节约成本。因此,在生产中,应根据实际需要灵活确定球果脱粒方式,从而达到既节约成本又能保证种子品质的目的。The quality of Chinese fir seeds is closely related to the way of threshing cones. The seed germination rate and seed yield obtained by drying and semi-drying are higher than those obtained by open-air turning-drying. There are significant differences, but the cost of drying is also high and the technology is difficult. The seed yield and germination rate of semisun and semi-drying method are not significantly different from those of drying method, but the cost can be saved. Therefore, in production, the method of threshing cones should be determined flexibly according to the actual needs, so as to achieve the goal of saving costs and ensuring the quality of seeds.
