中文摘要：

以培育富硒森林蔬菜为目标，在暗棕壤上进行了荚果蕨、小叶芹、小根蒜、婆婆丁等4种山野菜施硒试验。硒肥种类为亚硒酸钠，施硒量为0．10～10．00mgkg^-1，直接施肥范围为0～15cm表土。经过一个完整的生长周期（1a）后测定土壤和植物硒指标。结果表明，典型暗棕壤对外源亚硒酸钠态硒具有较强吸收与保持能力，从低剂量至高剂量施人的硒有90％～70％以上仍保留在原施硒土层内；其中H2O可溶态硒占全硒的6．03％～3．78％，KH2PO4浸提的有效态硒占全硒的19．36％～37．54％，而且土壤全硒、KH2PO4浸提的有效态硒及H2O可溶态硒皆与最初的施硒量呈线性正相关。在土施强化供硒条件下，4种山野菜均能高量富集硒，其含硒量为对照的1．7～158．9倍；不同植物的富硒能力有差异，它们在递增施硒情况下高量富集硒的变化模式也各有特点。总体来看，山野菜含硒量与施硒量之间为非线性正相关关系，但在一定的较低施硒量范围内这种关系则是线性的，线性范围因植物而异；土壤的可溶态硒、KH2PO4浸提的有效硒甚至全硒等指标与山野菜含硒量之间亦均呈明显的非线性正相关，且施硒量较低时其关系亦表现为线性。初步得出，典型暗棕壤控制施硒是在近自然条件下培育富硒森林蔬菜并获取高富硒生物资源的有效途径；不过，强烈搅动的砂砾质暗棕壤却不利于硒肥保持和植物吸收，不适于富硒森林蔬菜栽培。

英文摘要：

To explore the resources of selenium-enriching forest vegetables, an experiment was carried out of cultivating four species of wild forest-vegetables, i.e. Matteuccia struthiopteris Todaro, Aegopodium alpestre, Taraxacum mongolicum and Allium macrostemon in Dark Brown Forest Soil, using Na2SeO3 for fertilization, varying in application rate from Se 0.10 to 10.00 mg kg^-1, directly into the top 15 cm soil layer. Soil and plant samples were collected and Se contents were determined one year （a full growth cycle） after the application. Results show that Typic Dark Brown Forest Soil displayed a high capacity of adsorbing and reserving around 90% - 70% of the applied Se, from low to high application rate, in the top 15 cm soil layer. Of the total soil Se, about 6.03% - 3.78% was water-soluble Se and 19.36% - 37.54% KH2PO4-extractable Se, they were all linearly related to the initial Se application rate. All the four species of wild-vegetables tested were found capable of accumulating Se extraordinarily from soils with strengthened soil selenium supply. And the Se contents in these plants were 1.7 - 158.9 times as high as that in the plants in control （ CK）, varying with the application rate. The four species of plants were very different from each other in Se accumulation capacity and in variation pattern of Se accumulation with increasing Se application rate. On the whole, plant Se content was non-linearly related to Se application rate, but when the application rate was low, a linear relationship was found and varying in range from species to species. It was also found that plant Se content was also significantly, positively but nonlinearly related to the contents of soil total Se, KH2PO4-extractable Se and water-soluble Se, and linearly related when the application rate was low. It is hence concluded that properly controlled soil Na2SeO3 application in Typic Dark Brown Forest Soil would be an effective way to cultivate Se-rich forest vegetables and to exploit Se-rich vegetable resources under the quasi-natu
