林牧系统的树木中豆科植物的比例减少并不影响其内部的氮吸收效率
《Journal of Plant Ecology》2023年第3期40-53,共14页Andrea Schmiedgen Martin Komainda Manfred Kayser Bettina Tonn Johannes Isselstein 
funded by the German Ministry of Education and Research(BMBF)under grant number(031B0510A);a part of the research project SIGNAL(Sustainable intensification of agriculture through agroforestry)within the Framework Program BONARES(Soil as a sustainable resource for the bioeconomy).
在以豆科植物为主的草地中,豆科植物通过生物固氮为草地提供氮(N)。以往对林牧系统的研究发现,树木附近的豆科植物比例下降,将导致N供应以及树间草坪收获的牧草中N浓度的空间变化。在自然生态系统中,氮吸收效率(NRE)随着养分限制而增加...
