摘要
本文对平武王朗自然保护区引种大熊猫主食竹生育规律进行了研究。选用引种3年后生长表现较好的糙花箭竹(Fargesia scabrida)、石棉玉山竹(Yushania lineolata)、冷箭竹(Bashania fangina)、青川箭竹(F.rufa)4个竹种生长量与本地缺苞箭竹(F.denudata)作对比。通过生长过程的数学模拟和多元变量分析,探明5个竹种竹笋—幼竹期生长节律,日生长率及其生长与气象因子的关系。结果表明:引种的4个竹种都能适应本区条件,但在生长量上存在着种间差异。发笋多、生长快、长势好的竹种是糙花箭竹、冷箭竹和石棉玉山竹。影响竹种高生长的主要因素是热量因子。
In this paper,the authors studied the regulation of height- growth and shooting of bamboos that were introduced to Wanglang Natural Reserve as Giant panda's food,which were Fargesia scabrida,Yushania lineolata,Bashania fangina,F.rufa and native F.denudata.Some relevant meteorological factors were considered. With the methods of mathematic simulation and multifactor analysis,the growth rhythm of shoot-juvenile bamboo of 5 species and the relationship between dialy growth and meteorological factors for each specie have been ascertained.The results show that the four introduced species can adapt the alien climatic condition,but growth value differed from each other.The most adaptative species which shoot and grow rapidly are Fargesia scabrida and Yushania lineolata.The quantity of heat is the major limit factor of height-growth.
