摘要/Abstract

摘要： 研究了王朗自然保护区3个密度的缺苞箭竹群落的土壤养分库和叶片养分元素再分配能力的相互关系。结果表明,不同密度箭竹群落的土壤N、K贮量没有显著差异,土壤P贮量随着密度增加而显著减少(P<0.01),土壤Ca和Mg贮量则随着密度增加而增加。不同密度的箭竹叶片N和K的再分配能力没有显著差异,叶片P的再分配能力随着密度的增加而显著增加,Ca和Mg随着箭竹密度的增加在凋落叶中有显著积累的趋势。这表明,基于密度的箭竹叶片养分元素再分配能力与土壤养分库的大小密切相关,可能的机理过程是不同密度的箭竹在生长发育过程中改变了土壤养分库的大小,土壤养分库通过反馈机制导致箭竹叶片养分元素再分配能力的变化,体现了土壤与植被之间的互动关系。综合分析表明,P可能是限制缺苞箭竹生长发育的重要因子。

Abstract: The stocks of soil nutrient and nutrient resorption in senescent leaves and the relationships between them under Fargesia denudata with three densities were investigated in Wanglang National Nature Reserve,Western Sichuan.The results showed that bamboo density influenced significantly on the stocks of N,P,K,Ca and Mg in the soil.The P stock decreased significantly with the increase of density (P<0.01),and the stock for D1,D2 and D3 was 0.274,0.222 and 0.158 kg·m^-2 ,respectively.However,the stocks of both Ca and Mg increased with the increase of arrow bamboo density,and the stocks of Ca and Mg for D1,D2 and D3 were 2.64 and 1.70 kg·m^-2 ,4.42 and 1.80 kg·m^-2 ,as well as 4.85 and 2.12 kg·m^-2 ,respectively.The differences of N and K stocks between different densities of bamboo community were not significant,and the stocks of N and K for D1,D2 and D3 were 1.10 and 3.19 kg·m^-2 ,1.04 and 3.30 kg·m^-2 ,as well as 1.06 and 3.19 kg·m^-2 , respectively.The capacity of nutrient resorptions in senescent leaves varied greatly with the density of the bamboo community.The resorption ability of P in senescent leaves increased with the increase of arrow bamboo density,and the percentage of P resorption was 45.3%,50.9% and 65.8% respectively.On the contrary,the resorption ability of Ca and Mg in senescent leaves decreased significantly with the increase of density,and the resorption percentages of Ca and Mg were -44.1% and 29.1%,-83.3% and 2.4%,as well as -120.8% and -215% respectively.The resorption ability of N and K in senescent leaves did not vary with the bamboo density,and the resorption percentages of N and K were 71.2% and 78.2%,70.8% and 80.0%,as well as 70.8% and 80.9% respectively.It is suggested that the soil nutrient pool related to arrow bamboo density was associated with the nutrient resorption in senescent leaves.Possible mechanism was that arrow bamboo growth would change soil nutrient pools,and in turn,the ability of nutrient resorption in senescent leaves also feed back to the soil nutrient pool.This reflected the interaction between soil and plant.P might be a main factor limiting the growth of arrow bamboo (Fargesia denudata).
