Nakai treated by different methods( A-harvesting and sowing simultaneously with episperm removed; B-harvesting and sowing simultaneously with episperm not removed) and different substrate nutrient bags( A-forest land topsoil; B-yellow soil∶ coarse sand = 1∶ 1; C-farmland soil). Results indicate that the seed germination rate of S. glabra seeds harvested and sowed simultaneously with episperm removed and not removed was as high as 97. 3%and 97. 1%,respectively; the seedling growth of sowing substrate A-forest land topsoil was the highest,the average seedling height,average ground diameter,average main root length,and average lateral root length was 12. 1,0. 21,8. 5 and 7. 0 cm,respectively.展开更多
