塔里木河上游绿洲农田不同生育期玉米根茎叶生态化学计量特征OA北大核心CSCDCSTPCD
Stoichiometry Characteristics of Root, Stem and Leaf of Maize in Different Growth Stages in the Upper Reaches of the Tarim River
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…查看全部>>
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.T…查看全部>>
