摘要:
研究绿洲农田玉米生态化学计量特征可揭示玉米对环境变化的响应，为绿洲农田生态系统的优化管理与绿洲资源的保护提供理论依据。以塔里木河上游绿洲农田玉米为研究对象，分析了不同生育期根、茎、叶的碳（C）、氮（N）、磷（P）化学计量特征。结果表明：玉米C，N，P含量均值分别为311.97，16.41，2.54 mg/g。玉米各器官C，N含量均表现为叶 > 茎 > 根，P表现为茎 > 叶 > 根，C：N和C：P比值大小顺序均为叶 > 根 > 茎，N：P则为叶 > 茎 >根。不同生育期玉米叶的C含量在拔节期最高，茎的C含量无显著差异，根的C含量是拔节期显著低于其他3个生育期；拔节期叶和茎的N元素含量显著高于其他生育期，根的N含量无显著差异；乳熟期叶的P含量显著高于其他3个生育期，乳熟期茎的P含量最低，成熟期根的P含量最高；成熟期玉米叶的C：N显著高于其他生育期，乳熟期根和茎的C：P均显著高于其他生育期，乳熟期叶的N：P显著低于其他生育期，成熟期根和茎的N：P显著低于其他生育期。各生育期中叶片所对应的N：P小于14，可知玉米生长更易受N元素限制。GLM分析表明，生育期对P，C：N和C：P，生境对C，N和N：P的影响最大。
Abstract:
The main purposes of this study were to reveal the adaptation mechanism of maize to environment change in oasis farmland, to provide scientific basis for optimal management of oasis farmland ecosystem and protection of oasis resources. We took maize of oasis farmland in the upper reaches of the Tarim River as the sites. The chemical characteristics of carbon (C), nitrogen (N) and phosphorus (P) in roots, stems and leaves of different growth stages were analyzed. The results showed that the mean contents of C, N and P were 311.97, 16.41 and 2.54 mg/g, respectively. The the mean contents of C, N in maize organs decreased in the order:leaves > stems > roots, and P in maize decreased in the sequence:stems > leafs > roots, the changes in C:N and C:P ratios followed the order:leaves > roots > stems, whereas the change in N:P follow the sequence:leaves > stems > roots. The contents of C, N, P and their ecological stoichiometry ratios in roots, stems and leaves were significantly different among four growth stages. By comparison and analysis, the content of C in leaf was significantly higher at jointing stage than other growth stages; C content of stem was not significantly different at different growth stages; C content of root was significantly lower than other growth stages. The contents of N in leaf and stem were significantly higher at jointing stage than other growth stages; while the content of N in root was not significantly different. P content of leaf was significantly higher at milking stage than other growth stages, while P content of stem was significantly lower at milking stage than other growth stages, the content of P in root was significantly higher during maturation stage. The C:N ratio in leaf at maturation stage was significantly higher than other growth stage, the C:P ratios of stem and root at milking stage were significantly higher than other growth stage, compared with other ratios, the N:P ratio of leaf was significantly lower at milking stage than other growth stages, the N:P ratios of stem and root were significantly lower at maturation stage than other growth stage. The ratio of N:P was less than 14, which indicated that the growth of maize was mainly limited by N. According to the factorial analysis of GLM, it was concluded that growth stages and organs had certain influences on the contents of C, N and P and the ratios. It showed that the content of P, the ratios of C:N and C:P were mainly depended on the growth stages, the contents of C, N and the ratio of N:P were mainly determined by the organs.
