摘　　要：大豆(Glycine max)、花生(Arachis hy-pogaea)是我国主要油料作物,国内外均曾用大豆作为模拟酸雨的试验材料。本文对大豆作了较详细的观察。在大田中进行了花生试验,研究酸雨对其产量的影响。Experiments are made on soybean and peanut plants,using simulated acid rain with diffe-r(?)nt pH values.The perceptable injury,plant height,leaf area,dry matter,chlorophyll con-tent,membrane eonductance of leaf cell and other productive parameters are measured undervarious acid rain conditions.Their acidity thresholds are also determined.Acid rains affectthe above parameters to various degrees,but an acid rain of pH 3.5 has some promotiveeffects on the dry matter weight per plant and economic yield of peanut.
