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, we studied the rules of bamboo growth and development of the introduced giant panda in Pingwuwanglang Nature Reserve. Three years after the introduction, the growth performance of Fargesia scabrida, Yushania lineolata, Bashania fangina and F.rufa was better than that of native bamboo Contrast with F. denudata. Through the mathematical simulation and multivariate analysis of the growth process, the relationship between the growth rhythm, the daily growth rate and the growth and the meteorological factors of five bamboo species bamboo shoots - young bamboo were studied. The results showed that all the four bamboo species introduced could adapt to the conditions in this area, but there were some species differences in their growth. More bamboo shoots, rapid growth, growing good species of bamboo are rough bamboo, cold bamboo and asbestos Yushan bamboo. The main factor affecting the growth of bamboo species is the heat factor.
