卧龙自然保护区冷箭竹(Sinarunndinaria fangiana)于1983年发生了大面积开花枯死,给大熊猫造成食物危机.为此,我们进行了冷箭竹的人工直播更新、人工促进天然更新、天然更新的试验.对1年生竹苗的比较和各种更新方式的分析,对冷箭竹的更新复壮提出初步看法.一 、试验地:在海拔2500—2600米的半阴坡处,其地理坐标约东径103°8′北纬30°57′,坡度10°,年平均温度6.26°C、年最高款24°C、年最低温-10.5°C, 4—10月平均相对湿
Sinarunndinaria fangiana in Wolong Nature Reserve suffered a large area of flowering and withering in 1983 and caused a food crisis for the giant panda, so we carried out artificial direct artificial regeneration of Artichoke, artificially accelerated natural regeneration and natural renewal experiments. The comparison of 1-year-old bamboo shoots and the analysis of various renewal methods put forward the preliminary view on the renewal and rejuvenation of A. chinensis I. Test place: at the semi-shady slope of 2500-2600 meters above sea level, its geographical coordinates about 103 ° 8 ’Latitude 30 ° 57’, slope 10 °, annual average temperature 6.26 ° C, annual maximum 24 ° C, annual minimum temperature -10.5 ° C, April-October average relative humidity
