摘要：

本研究在富硒栽培灰树花的基础上,考查硒镧复合栽培灰树花对其营养成分的影响。通过配置不同的硒镧配施水平,对灰树花子实体产量、硒含量、成分和重金属含量进行研究。结果显示,硒镧配施浓度为Na2SeO3 40 mg/kg+ LaCl3 80 mg/kg,灰树花产量显著(P<0.05)高于对照(Na2SeO3 0 mg/kg+ LaCl3 0 mg/kg)。当配施浓度为Na2SeO3 80 mg/kg+ LaCl3 80 mg/kg,子实体的硒含量最高,极显著(P<0.01)高于对照。子实体成分测定结果表明,配施浓度为Na2SeO3 40 mg/kg+ LaCl3 80 mg/kg,粗蛋白含量显著(P<0.05)高于对照,氨基酸总量极显著(P<0.01)高于对照;配施浓度为Na2SeO3 80 mg/kg+ LaCl3 80 mg/kg,总糖含量显著(P<0.05)高于对照,其余成分含量相对于富硒栽培均增加。当配施浓度为Na2SeO3 80 mg/kg+ LaCl3 80 mg/kg时,子实体中铅、镉、汞、砷含量极显著(P<0.01)低于对照。可见,配施适宜浓度的硒镧可提高灰树花子实体产量、硒含量、成分含量（总糖、粗蛋白、粗脂肪和氨基酸等）,降低铅、镉、汞、砷等重金属含量。

Abstract:

Based on the selenium-enriched cultivation of Grifola frondosa, the effects of selenium (Se) and lanthanum (La) compound cultivation on the nutritional components of G. frondosa were studied. By applying different levels of Se and La in combination, this paper studied the yield, Se content, chemical composition and heavy metal content of the fruiting body of G. frondosa. The results showed that compared with that of the control (Na2SeO3 0 mg/kg+ LaCl3 0 mg/kg), the yield of G. frondosa was significantly higher under Se and La combined application (Na2SeO3 40 mg/kg+ LaCl3 80 mg/kg) (P<0.05). When the combined application concentration was Na2SeO3 80 mg/kg+ LaCl3 80 mg/kg, the Se content in the fruiting body was the highest, which was significantly higher than that of control (P<0.01). The results of the fruiting body composition analysis showed that when the combined application concentration was Na2SeO3 40 mg/kg+ LaCl3 80 mg/kg, the crude protein content was significantly higher than that of the control (P<0.05) and the amino acid content was very significantly higher than that of the control (P<0.01). When the combined application concentration was Na2SeO3 80 mg/kg+ LaCl3 80 mg/kg, the total sugar content was significantly higher than that of the control (P<0.05), and the contents of other components were increased compared with Se-enriched cultivation. When the combined application concentration was Na2SeO3 80 mg/kg+ LaCl3 80 mg/kg, the content of lead, cadmium, mercury and arsenic in the fruiting body were significantly lower than those of control (P<0.01). The study shows that cultivating G. frondosa with appropriate concentration of Se and La could increase the yield, Se content, and composition contents (total sugar, crude protein, crude fat, amino acid and etc.), and decrease the heavy metal contents in the fruiting body.
