摘　　要：以"礼品2号"核桃为材料,研究不同浓度的硒处理对核桃叶片的光合速率以及叶片质量的影响。结果表明,随着施入硒浓度的增加,光合速率逐渐增大,维持叶片原本的绿色,降低被病虫侵染的频率,促进枝条早熟。硒处理还可以提高土壤和核桃叶片中的硒含量。Taking ＂Lipin No.2＂ as material, this paper studied the effects of different concentrations of selenium on the photosynthetic rate and leaf quality of walnut leaves. The results showed that the photosynthetic rate increased gradually with the increase of the concentration of selenium, to maintain the original green leaf, and the probability of being infected by disease and insect, and promote the early maturing. Se treatment can also improve the selenium content in the soil and walnut leaves.
