The different concentration of selenium on selenium content and growth effect of Ampelopsis grossedentata

摘要: 以多年生木质藤本植物藤茶为材料进行盆栽实验,探讨硒肥浓度对藤茶硒的吸收变化规律及生长发育的影响,优选出适宜的硒肥浓度,为富硒藤茶大规模栽培和开发利用提供依据。结果表明,一定浓度的硒肥对藤茶根、茎、叶的生长具有显著促进作用,并对藤茶的花序重量具有显著影响。随着硒的浓度升高,藤茶硒含量呈现整体升高的规律,硒浓度增大到一定程度时硒含量增加不显著。综合藤茶富硒规律及生长发育的影响可知,富硒藤茶的施硒浓度为5~10 mg/kg,在此浓度范围内硒对藤茶生长发育有积极影响且富硒含量较高。Abstract: The perennial woody vines Ampelopsis grossedentata was used as materials for pot experiment,to selecte the suitable concentration of selenium fertilizer by exploring selenium changes and growth of Ampelopsis grossedentata under the conditions of different concentrations of Selenium. This experiment aimed at providing the basis for the large- scale cultivation and utilization of selenium- rich Ampelopsis grossedentata. The main results was as follows: a certain concentration of selenium fertilizer had significant influence on promoting the root,stem and leaf growth and inflorescence weight. With the increase of concentration of selenium treatment,the selenium content of Ampelopsis grossedentata showed elevation overall. When selenium concentration increased to a certain extent,selenium content of Ampelopsis grossedentata was not significantly increased.Comprehensive selenium enrichment and growth of effect showed that selenium concentrations of selenium enriched Ampelopsis grossedentata was 5~10 mg / kg.This range of concentration of selenium on the growth and development had a positive impact and Ampelopsis grossedentata high selenium content.
