摘要
[目的]探索鱼菜共生系统中矿物元素对蔬菜生长以及品质的影响。[方法]向传统鱼菜共生系统中,逐步投放麦饭石、火山石以及陶粒,定期测定蔬菜水培营养液中矿物元素以及重金属含量,并在蔬菜收获时测定其高度、叶片数、重量以及叶绿素含量等指标。[结果]在鱼菜共生系统中投放麦饭石等可提高水培营养液中矿物元素含量,对照组蔬菜根长对比空白组增长15.60%,株高增高19.68%,质量和生物产量分别增长18.64%和34.38%。[结论]麦饭石等的投放可增加水体中矿物元素含量,促进鱼菜共生系统中蔬菜的生长,并可提高蔬菜叶绿素含量,且不会造成重金属超标,但火山石、麦饭石以及陶粒的投放比例、投放方式和投放量还需要进一步研究。
[Objective]To find out the effects of mineral elements on vegetable growth and quality in aquaponics system.[Method]The vesuvianite, maifanite and ceramsite were added to the system, the concentrations of Fe, Mn, Mg, K and Ca were determined, as well as the height, weight, leaves and chlorophyll content, et al. of the vegetable.[Result]The concentrations of Fe, Mn, Mg, K and Ca were higher after adding the vesuvianite, maifanite and ceramsite compared to the blank, the growth and quality of vegetable were also better, i.e., the length of root was increased by 15.60%, the height of the whole vegetable was increased by 19.68%, and the weight and production were increased by 18.64% and 34.38% respectively.[Conclusion]Adding vesuvianite, maifanite and ceramsite is an approach to increase the mineral elements in aquaponics system, which promotes the growth and quality of vegetable, however, the proportion, the way of addition and the amount are needed for further research.
