通过对苦丁茶施硒肥的盆栽试验,探讨硒对粗壮女贞主要内含物和品质的影响。结果表明,根部施亚硒酸钠对粗壮女贞主要内含物含量的提高及品质的改善都非常有利。当硒浓度为1mg/L时,施后30d,粗壮女贞硒含量最高,达到1.516μg/g;硒浓度为3.0mg/L时粗壮女贞叶片主要内含物含量最高。同时显著提高了游离氨基酸和水浸出物的含量,硒浓度为1mg/L时游离氨基酸和水浸出物的含量为对照的120.11%和117.65%,其中酚氨比含量下降为对照的87.38%。
Through pot experiment of applying Kuding tea with selenium fertilizer, the effects of selenium on the main contents and quality of Prunella vulgaris were discussed. The results showed that root application of sodium selenite on the main content of Prunus cassiii improve the content and improve the quality are very beneficial. When the concentration of selenium was 1 mg / L, the content of selenium in Prunus trilobata was the highest at 1.5 dg / g after 30 d and the content of main contents in the prunus persica was the highest at selenium concentration 3.0 mg / L. At the same time, the contents of free amino acids and water extracts were significantly increased. The contents of free amino acids and water extracts at the concentration of 1 mg / L were 120.11% and 117.65% of the control respectively, and the content of phenolic ammonia decreased to 87.38% of the control.
