摘要
为阐明沿海沙地不同竹种对沙地环境的适应能力及其生存策略,选择福建省漳州市赤山国有林场的花吊丝竹(Dendrocalamus mi-nor var.amoenus)、青丝黄竹(Bambusa eutuldoides var.viridi-vittata)、鼓节竹(Bambusa tuldoides'Swollenintrnode')、青皮竹(Bambusa texti-lis McClure)4种竹子为研究对象,采用方差分析、多重比较等研究方法对其地上各器官生物量分配进行研究.结果表明:移植后经过 2年,4种竹子对沿海沙地环境的适应性都有所增强.从地上部分各器官含水率来看,青丝黄竹、鼓节竹与青皮竹表现为竹秆＞竹枝＞竹叶,花吊丝竹表现为竹秆＞竹叶＞竹枝.单株地上部总生物量表现为花吊丝竹＞青皮竹＞青丝黄竹＞鼓节竹.各器官占地上生物量的比率也有所差异,青丝黄竹、鼓节竹和青皮竹表现为竹秆＞竹枝＞竹叶,而花吊丝竹表现为竹秆＞竹叶＞竹枝.
Abstract
To elucidate the adaptability and survival strategies of different bamboo species in coastal sandy land.Dendrocalamus minor var.amoenus,Bambusa eutuldoides var.viridi-vittata,Bambusa tuldoides'Swollenintrnode',Bambusa textilis McClure were selected from Chishan National Forest Farm in Zhangzhou City,Fujian Province.and their aboveground biomass allocation was studied by variance analysis and mul-tiple comparisons.The results showed that after 2 years of transplantation,the adaptability of the four bamboos to coastal sandy land increased.According to the moisture content of the aboveground organs,the order of Bambusa eutuldoides var.viridi-vittata,Bambusa tuldoides'Swollen-intrnode'and Bambusa textilis McClure was bamboo stalk＞bamboo branch＞bamboo leaf,the order of Dendrocalamus minor var.amoenus was bamboo stalk＞bamboo leaf＞bamboo branch.The total biomass of aboveground parts of each plant is Dendrocalamus minor var.amoenus＞Bam-busa textilis McClure＞Bambusa eutuldoides var.viridi-vittata＞Bambusa tuldoides'Swollenintrnode'.The biomass ratios of different organs were also different.the bamboo stalk＞bamboo branch＞bamboo leaf of Bambusa eutuldoides var.viridi-vittata,Bambusa tuldoides'Swollenin-trnode'and Bambusa textilis McClure,The bamboo stalk＞bamboo leaf＞bamboo branch of Dendrocalamus minor var.amoenus.
