摘要
用野外调查测定和室内模拟的方法研究了温度对小叶海金沙生长的影响。结果表明,小叶海金沙疯狂生长群落中的温度比正常生长群落高,且温度与其净光合速率呈极显著正相关,而这两种类型群落内大气相对湿度以及光照差异较小。此外,土壤养分和土壤pH与小叶海金沙的生长速度无明显的关联性。根据研究结果推测:温度可能是小叶海金沙疯狂生长原因之一。
Effects of temperature on Lygodium scandens were studied using field investigation and simulation. Results showed that the temperature in overspreading community was higher than that in natural community, and it was positively related to the net photosynthetic rate of L. scandens （p〈0.001）. There was no significant variation in relative humidity and light intensity between the two communities. No significant relationships were found between the overspreading and soil nutrition as well as its pH. Results suggested that temperature might be one of the factors for the rapid growth of L. scandens.
