摘　　要：为探明土壤硒含量对花生硒含量的影响,以19个花生品种为供试材料开展常规田间栽培试验,设置硒含量0.42 mg/kg(A)、0.73 mg/kg(B)、1.08 mg/kg(C)共3个处理,采用大田随机区组设计,研究不同土壤硒含量对花生籽仁硒含量与硒富集系数的影响。结果表明:不同品种在不同处理条件下的籽仁硒含量、硒富集系数均有较大的差异,范围分别为0.102~0.306 mg/kg、11.32%~40.16%,籽仁硒含量均符合广西地方标准(DB45T 1061-2014)中富硒花生硒含量(0.05~0.5 mg/kg)的限值范围要求;花生品种间天然存在富硒能力的差异,同一品种在处理C条件下花生的籽仁硒含量较高,在处理A条件下花生的硒富集系数较高;‘桂花黑1号’的籽仁硒含量和硒富集系数在不同处理条件下均为参试品种中的最高值。研究发现,‘桂花黑1号’在不同硒含量的土壤中均表现出高效且稳定的硒富集能力,是生产天然富硒花生的优良品种。研究旨在为富硒产业提供优良的富硒品种,也为华南天然富硒土壤资源的利用提供理论依据。In order to ascertain the influence of soil selenium content on peanut selenium content,a total of 19 peanut varieties were used as materials.Three discrete treatments of soil selenium content were employed,comprising 0.42 mg/kg(treatment A),0.73 mg/kg(treatment B)and 1.08 mg/kg(treatment C).The impact of varying soil selenium levels on the selenium content and selenium enrichment coefficient of peanut seed kernels was evaluated.A field trial was conducted using a randomised block design.The results demonstrated considerable variability in the selenium content and selenium enrichment coefficients of the seed kernels of the different varieties in the different treatments,with ranges of 0.102-0.306 mg/kg and 11.32%-40.16%,respectively.The seed kernel selenium content was found to be consistent with the specified limit value for selenium content in selenium-enriched peanuts(0.05-0.5 mg/kg)as outlined in the regional standard of Guangxi(DB45T 1061-2014).The seed kernel selenium content of peanuts was found to be higher under treatment C,while the selenium enrichment coefficient of peanuts was higher under treatment A.Among the participating varieties in diverse treatments,the seed kernel selenium content and selenium enrichment factor of'Guihuahei 1'were found to be the highest.'Guihuahei 1'shows efficient and stable selenium enrichment ability in soils with different selenium contents,and is an excellent variety for producing natural selenium-rich peanuts.
