黑龙江水湿生鸢尾研究

The Reproductive Technical Study of Aquatic and Hygrophytic Species of Iris in Heilongjiang

通过移栽在相同环境中的系统观察和不同水分与温度条件下的对比试验,研究了黑龙江产水湿生鸢尾玉蝉花(Iris ensata)、燕子花(I.laevigata)、乌苏里鸢尾(I.maackii)和原产欧州的黄菖蒲(I.pseudacorus),认为乌苏里鸢尾与黄菖蒲无论形态特征或发育节律都极其相似,在园林应用上可视为黄菖蒲。玉蝉花宜种子繁殖,燕子花与黄菖蒲宜根茎繁殖,且更喜水。三者均为北方城市水湿生环境好的绿化材料。

The systematic observations and comparisons of the aquatic and hygrophytic Iris spp. transplanted to different environments, which include I. ensata, I. laevigata, and I. maakii native to Heilongjilang and L. psendacorus native to Europe, in different water and temperature conditions are used in this paper. We observed that the morphological characters and developmental rhythm of I. rnaaekii are very similar to that of I. pscudacorus and therefore both taxa should be the same species. The seminification should be suitable for I. eusata, but rhizome propagation is appropriate to I. laevigata and I. psendacorus. All three species of Iris are good garden plants for the northern cities, especially the aquatic and bygropbytic environments.
