Competition, temperature, and nutrient are the most important determinants of tree growth in the cold climate on the eastern Tibetan Plateau. Although many studies have reported their individual effects on tree growth, little is known about how the interactions of competition with fertilization and temperature affect root growth. We aim to test whether climate warming and fertilization promote competition and to explore the functional strategies of Picea asperata in response to the interactions of these factors.

增温施肥与种内竞争相互作用对云杉云杉优良根系性状的影响

竞争，温度和养分是青藏高原东部寒冷气候下树木生长的最重要决定因素。尽管许多研究报告了它们对树木生长的个体影响，但对于竞争与施肥和温度之间的相互作用如何影响根系生长的了解很少。我们旨在测试气候变暖和施肥是否促进竞争，并探索云杉的功能策略以应对这些因素的相互作用。
