| 摘 要： | 分别采用麦饭石和陶粒颗粒处理作为鱼菜共生系统无土栽培及养殖水过滤基质，对生菜株高、根长、地上部鲜质量及叶绿素含量等指标测定，以及对乌鳢鱼养殖过程中存活率、增重率和水体pH值、溶解氧含量等水质指标测定。试验结果表明，在鱼菜共生系统中投放麦饭石可有效提高生菜和乌鳢生长发育水平，试验组比对照组根长、株高、单株质量、叶绿素含量分别增加18-4%、15-0%、21-9%、45-8%；乌鳢鱼养殖过程中试验组比对照组的pH值高0-42，溶解氧高0-69 mg/L，死亡率降低7-6%，增加质量提高23-68%。试验证明麦饭石在鱼菜共生系统中性质稳定，对蔬菜、乌鳢的生长发育及水体保持具有较好的效果。

Effect Test of Maifan Stone on Fish Vegetable Symbiosis System |
| |
| Abstract: | Maifan stone and ceramsite particles were used as substrates for soilless culture and aquaculture water filtration in fish vegetable symbiosis system respectively.Plant height，root length，aboveground fresh weight and chlorophyll content of lettuce，survival rate，weight gain rate of snakehead，and pH value，dissolved oxygen content of water quality were measured.Test results showed that growth and development of lettuce and snakehead could be improved by adding maifan stone in fish vegetable symbiosis system.Compared with control group，root length，plant height，weight and chlorophyll content of test group increased by 18-4%，15-0%，21-9% and 45-8% respectively.In the process of snakehead culture，compared with control group，pH increased by 0-42，dissolved oxygen content by 0-69 mg/L，mortality reduced by 7-6%，and weight gain increased by 23-68% of test group.Test proofed that maifan stone was stable in fish vegetable symbiosis system，and had good effect on growth and development of vegetables and snakehead，and water conservation. |
