| 摘 要： | 选取闽江河口湿地入侵植物互花米草（Spartina alterniflora）为研究对象，测定其各个构件生物量和钾元素含量季节变化，结果表明：互花米草地上部分各个构件钾元素含量从春季到冬季逐渐减少，除夏季外，其余季节绿茎和绿叶钾元素含量显著高于立枯部分（P〈0．05），花仅出现在秋冬季节，且在秋季钾元素含量达到峰值（8...

| Abstract: | Taking the invasive Spartina alterniflora in the Minjiang River estuary as test objectives,this paper studied the seasonal dynamics of kalium and biomass in different organs of S. alterniflora. The results showed that,on one hand,the kalium content in different organs of aboveground S. alterniflora was reduced gradually with the growing process in the general changing trend within a growing season. Except in the summer,the kalium content in green part was significantly higher than standing dead of S. altern... |
