几个鸢尾新品种栽培研究

Study on Several New Variety of Iris germanica in Zhengzhou

对几种在郑州地区新引进的德国彩花鸢尾进行了栽培研究。结果表明:不朽白和黑骑士生长较旺,花朵较大,但开花率低,花期较短,繁殖系数低;黄娃娃和血石长势中庸,花朵中等,开花率高,花期较长,繁殖系数也高;金娃娃与黄链长势中庸偏下,花朵较小,但花期较长,金娃娃繁殖系数中等,黄链繁殖系数最低;紫边白植株矮小,长势较弱,花朵也小,但花期较长,繁殖系数较低。无论任何品种在郑州地区均能良好生长,且其生长、开花、繁殖均与土壤肥沃、疏松、排水良好呈正相关。

This paper made a series studies of growth to several new variety Iris germanica, introduced in the region of Zhengzhou. The result indicated： Buxiubai and Heiqishi grow very vigorously, the flower was larger, hut the rate of bloom was lower, the time of bloom was shorter, the rate of propagation was lower; Huangwawa and Xueshi grow middling, the flower was middling, the rate of bloom was higher, the time of bloom was longer, the rate of propagation was higher too ;Jinwawa and Huanglian grow mid-lower, the flower was little, but the time of bloom was longer, the rate of propagation of Jinwawa was middling,the rate of propagation of Huanglian was lowest than other,the plant of Zibianbai was undersized, its growth was weak,the flower was little too,but the time of bloom was longer,the rate of propagation was lower. The several new variety Iris germanica, were able to grow well in region of Zhengzhou, and their growth,bloom,propagation,all had a positive relation with the fertile and loose soil,it drain all right.
