摘　　要：研究了在温室内用盆栽法,其土壤含水量对茶条槭、山梨和山桃三种阔叶树苗光合作用的影响,以及各树种在土壤相对含水量为75.0%时光合作用的日变化。Using potted plant method in glasshouse, this paper studies effect of soil water content impact on photosynthesis of three broad- leaved trees, which are Acer ginnala Maxim, Mountain ash berry and David peach. It also studies the photosynthesis daily variation of each tree species when the relative soil water content is 75 %.
