本文研究了不同浓度营养液对花鱼共养的影响,采用0、1/8、1/4三个处理的Hoagland营养液,对花和鱼的生长势进行了研究,得出较为合理的花鱼共养技术。试验结果表明,皇冠(Echinodorus amazonicus)、虎耳草(Bacope carolinian)、茶叶草(Ludwigia palustris)和鱼在1/8浓度Hoagland营养液中生长最好,该浓度营养液下植物的茎长、叶片数、根长、须根数、干重和鱼的成活率均较高,是较为理想的花鱼共养的营养液。水生植物是指生长于水体中、沼泽地中的观赏植物,与其他花卉明显不同的习性是对水分的要求和依赖远远大于其他各类,因此也构成了其独特的习性[1]。
In this paper, the effects of different concentrations of nutrient solution on the co-culture of fish were investigated. The growth potential of flowers and fish were studied using Hoagland nutrient solution at 0, 1, 8 and 1/4 treatments, and the more reasonable flower Fish culture technology. The results showed that Echinodorus amazonicus, Bacope carolinian, Ludwigia palustris and fish grew best in Hoagland nutrient solution at 1/8 concentration, Number, root length, number of fibrous roots, dry weight and survival rate of fish are higher, is the ideal of fish culture solution. Aquatic plants refer to ornamental plants that grow in the water and marshes. The obvious difference from other flowers is their habitual demand and dependence on water, which is far greater than all other types of aquatic plants and therefore constitutes their unique habitat.
