| 摘 要： | 为了在不同土壤环境下选育出低镉(Cd)积累型花生品种以提高花生品质，以‘白沙1016号’品种花生(Arachis hypogaea L.)为供试作物，棕壤和潮土为供试土壤，采用盆栽试验的方法，研究了2种类型土壤对花生籽实Cd积累特性的影响。结果表明：2种类型土壤条件下的花生籽实生物量差异显著（P<0.05）；在供试土壤Cd处理范围内(≤10.0 mg/kg)，籽实生物量均随2种土壤Cd处理浓度增加呈“低促高抑”现象。花生籽实对土壤Cd的生物富集系数均随2种土壤Cd处理增加呈显著降低趋势（P<0.05），且土壤类型间差异不显著。花生籽实Cd含量和Cd生物富集量均随2种土壤Cd处理的增加而显著增加（P<0.05），但两者在棕壤介质中均显著大于潮土（P<0.05）。土壤类型对花生籽实Cd积累差异的影响主要体现在籽实Cd含量和生物富集量方面。而土壤pH、氧化还原电位(Eh)等均是影响籽实对Cd积累差异的重要因素。 |

| Abstract: | To select peanut cultivars of low absorption in different soil and improve the quality of peanut,a pot experiment was conducted with one kernel variety of‘Baisha 1016’under two soil of types（burozem and fluvo-aquic soil） to study the effect of the two soil types on characteristics of Cd accumulation in kernels of peanut（Arachis hypogaea L.）.The results indicated that biomass of peanut kernel in two types of soil tread with the same Cd concentration had no significance at 95% probability.Within the range of soil Cd treatments in the experiment,the biomass of peanut kernels exhibited the phenomenon of＂hormesis effect＂with the increasing of Cd concentrations in soil.Bioaccumulation factor（BF） of Cd in kernels of peanut decreased significantly（P0.05） with the increasing of Cd concentrations in soil and there was no significant difference between the two types of soil（P0.05）.Cd contents and bioaccumulation capacity in kernels of peanut increased significantly（P0.05） with the increasing of Cd concentrations in soil and were higher in burozem than that in fluvo-aquic soil.The effect of soil type on Cd accumulation in kernels of peanut was mainly reflected in the bioaccumulation capacity of Cd in kernels of peanut.Peanut kernels accumulation ability to Cd in soil was related with the soil pH,redox potential and so on. |
| Keywords: | peanut（Arachis hypogaea L ） kernel soil type Cd burozem fluvo-aquic soil bioaccumulation capacity |
