结合新疆的环境特点，对蕨状满江红（Azolla filiculoides Lam.）进行了一系列引种适应性试验和生物学功能测定。结果表明：蕨状满江红在新疆有很强的适应性，在5-40℃均能生长，其生长最适温度为℃，且耐低温；在2-8g/L的盐溶液及pH4-10范围内也能生长，并且可降低水体的矿化度及pH值；具有净化养殖水体和很强的富钾能力，植株钾含量最高可达干重的9.66％；水利用率高，并能有效减少养殖水体表面的蒸发，有保水作用。在新疆的河、湖和水库适量养殖蕨状满江红，可实现其生态与经济价值。 |

A series of experiments of ecological adaptability with introduced species Azolla filiculoides Lam. were carried out considering environmental characteristics in Xinjiang. The results showed that this species has strong adaptability to local climate in Xinjiang. It can grow in a temperature of 5 - 40℃ and the optimal temperature is between 25 - 30℃. The species can survive in solution with a salt content of 2 - 8 g/L and pH value of 4 - 10, the salt content and pH value of solution are both reduced. Meanwhile, the water quality can be improved by cultivating of the species. It has a important function in accumulating potassium, whose content in dry weight is up to 9.66% . Water use efficiency of the species is rather high, and it can reduce evaporation on water surface. According to these characteristics it is possible to realize its ecological and economic values if it is cultivated in rivers Uakes and reservoirs properly. |
