摘要:
为了解不同人工林叶片C、N、P含量及其化学计量特征的季节变化规律,以福建三明格氏栲和杉木人工林为研究对象,分不同季节采集其新鲜成熟叶片进行分析。结果显示:(1)格氏栲叶片C、N、P及其计量比(C:N、C:P、N:P)分别为488.48 g/kg、15.67 g/kg、0.93 g/kg和31.87、537.16、17.32,杉木为501.99 g/kg、13.67 g/kg、1.00 g/kg和37.32、511.55、13.97,其中格氏栲叶片N含量、N:P显著高于杉木,C含量、C:N显著低于杉木,P含量和C:P与杉木无显著差异。(2)格氏栲和杉木叶片C含量均表现为从春季到冬季先升高后降低,秋季达到最大,格氏栲叶片N含量为秋季最低,而杉木叶片N含量为秋季最高,格氏栲叶片P含量为夏季最高,春季最低,而杉木叶片P含量为春夏季显著低于秋冬季。(3)格氏栲和杉木叶片C:N、C:P变化趋势与其N、P含量变化趋势相反,叶片N:P与其P含量变化趋势相反,说明叶片N、P含量对叶片C:N与C:P起主导作用,叶片N:P主要由P含量决定。(4)除叶片C含量和C:P外,其他指标均受季节和树种及其交互作用的显著影响;叶片C:P主要受季节的影响,其他各指标受树种的影响最大。研究表明,杉木人工林N的利用效率高,格氏栲人工林P的利用效率高,根据不同季节叶片N、P含量及化学计量比,格氏栲在春冬季受P限制,秋季受N限制,夏季同时受N、P限制,杉木在秋冬季受N限制,春夏季同时受N、P限制。(图1表3参38)
Abstract:
In order to understand the seasonal variations of C, N and P contents and their stoichiometric characteristics in leaves of different plantations, fresh leaves of Castanopsis kawakamii and Cunninghamia lanceolata Plantations were collected and analyzed in different seasons in Sanming, Fujian. The results showed that: (1) Leaf C, N, P concents and their stoichiometric ratios (C:N, C:P, N:P) of C. kawakamii were 488.48 g/kg, 15.67 g/kg, 0.93 g/kg and 31.87, 537.16 and 17.32, respectively, and the same parameters of C. lanceolata were 501.99 g/kg, 13.67 g/kg, 1.00 g/kg and 37.32, 511.55 and 13.97, respectively. the N contents and N:P of leaves were significantly higher in C. kawakamii than in the C. lanceolata, the C contents and C:N of leaves were significantly lower in C. kawakamii than in the C. lanceolata, there were no significant difference of P contents and C:P between C. kawakamii and C. lanceolata. (2) The leaf C contents of C. kawakamii and C. lanceolata increased first and then decreased from spring to winter, and reached the maximum in autumn, and the leaf N contents of C. kawakamii was the lowest in autumn. However, the leaf N contents of C. lanceolata leaves was the highest in autumn, the leaf P contents of C. kawakamii was the highest in summer and lowest in spring, while the leaf P contents in spring and summer were significantly lower than that in autumn and winter of C. lanceolata. (3) The change trend of C:N and C:P in leaves of C. kawakamii and C. lanceolata were opposite to that of N and P contents, leaf N:P showed an opposite trend to P content, It indicates that N, P contens played a predominant role in determining C:N and C:P ratios, meanwhile, N:P ratio was controlled by P content. (4) Except for C contents and C:P in leaves, other indicators were significantly affected by season and tree species and their interaction; C:P in leaves was mainly affected by season, and other indicators were most affected by tree species. The result indicates that the utilization efficiency of N was highest in C. lanceolata plantation, and the utilization efficiency of P was highest in C. kawakamii plantation. according to the content and stoichiometric ratio of N and P in leaves in different seasons, C. kawakamii was under P limitation in spring and winter, and N limitation in autumn, N and P co-limitation in summer, C. lanceolata was under N limitation in autumn and winter, N and P co-limitation in spring and summer.? ? ??
