水生植物与花鱼共养

Aquatic Plants and Flower and Fishes Living Together

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]。

The influence of different consistency nutrient fluid on flower and fishes living-together was studied in this paper. Selecting three treatments of 0, 1/8, 1/4 Hoagland nutrient fluid, the growth potential of flower and fishes living-together was noted and a reasonable technique was gained. The results indicated that Echinodorus amazonicus, Bacope Carolinian, Ludwigia palustris and fishes lived well at the 1/8 consistency of nutrient fluid which is the perfect nutrient fluid. The grass height, number of leaves, root length, number of fibrous root, dry biomass and the survival rate are high. Aquatic flower is the ornamental plants which live in water and everglade, it significantly differ from other flowers because of its high demand and reliance of water.
