不同土壤pH和铵硝态氮配比对杉木和木荷幼苗叶片C、N、P化学计量的影响
Effects of different soil pH and ammonium nitrate nitrogen ratio on C,N and P stoichiometry in leaves of Cunninghamia lanceolata and Schima superba seedlings
[目的]研究不同土壤pH和铵硝态氮配比环境下对杉木和木荷幼苗叶片C、N、P化学计量特征的影响,探讨适合杉木和木荷生长的最佳pH和铵硝态氮配比环境,为提高杉木木荷混交林林地生产力提供理论依据。[方法]本研究以一年生杉木和木荷实生苗为研究对象,设置 3个栽培基质pH水平:pH= 4.5、pH= 5.5、pH =6.5,在N素总量相等的条件下设置 5个铵硝配比(NH4+-N∶NO3--N)处理:10:0、7∶3、3∶7、0∶10、5∶5(对照:均一分布…查看全部>>
[Objective]The effects of different soil pH and ammonium nitrate nitrogen ratio on the C,N and P stoichiometric characteristics of leaves of Cunninghamia lanceolata and Schima superba seedlings were studied,and the optimal pH and ammonium nitrate nitrogen ratio environment suitable for the growth of C.lanceolata and S.superba seedlings was discussed,providing a theoretical basis for improving the forest productivity of C.lanceolata and S.superba mixed forest…查看全部>>
