Abstract:

Ilexfargesii is the fine evergreen broad-leaved tree species of northern China，but it is quite difficult to propagate．Using the oahogonal experiment design method，techniques on sowing and growing seedling of Ilex fargesii were studied．The results show that different mediums，different shading treatments and different seed treatments have significant influence on emergence rate of seedlings and quality of seedlings of Ilex fargesii．The optimum scheme of seedling-raising of Ilex fargesii is using humus soil，using single-layer shading net with 50% sunlight permeability rate，soaking the seeds with dense sulphuric acid and 250 mg kg^-1 GA_{3 for 24 hours，and stratification treatment．}
