Abstract:Using Abies georgei as the experimentary material, trials of different sowing date, different daylight intensity(shade)and overwintering under various covering materials were carried out in 1982—1984 at the experimentary nursery of Xiao-Zhongdian Forest Service of Yunnan province. The results were as follows:1. Shade in a certain extent was necessary for seedlings of Abies georgei in the subalpine regions of Yunnan province and 30—70% of natural daylight intensity showed better effects on survivals of seedlings. The seedlings grown in dry season were damaged by the direct sunshine exposure. But the lowered intensities which were less than 15% of the natural sunshine irradiation caused bad quality of seedlings due to the insufficient photo-energy which affected the photosynthesis of the seedlings and resulted in low biomass.2. The biomass and growing speed of sown in winter were highest than in spring and summer, and the value of NAR was higher too, because sown in winter had a longer growing season and the NAR peak value was moved up and appeared on the second ten days of June, while summer seeding the NAR peak value appeared on the third ten days of July. it should be preached to seed in winter.3. The overwintering of seedlings of Abies georgei showed quite low percentage of survival, only 24.7%. The higher survival rate 88.8% was obtained under the condition that the seedlings were coyered with rice straw with 5—7 cm deep. This measure is feasible.
