4个花葱品种引种湖南地区的物候期及生长特性分析

摘要

为了丰富湖南地区的球根花卉种类，从荷兰引进4个不同品种的花葱进行种植，对它们在湖南引种的物候期、观赏特性及生长状况进行观察及分析。结果表明：4个花葱品种的耐寒性较强，出苗期均在2月，出苗率在85%以上，叶片展开期在3月15~27日；除相册外3个花葱品种均具有良好的观赏性能，花朵大，色彩艳丽；且3个品种均只有1个花枝，花茎长度在80.5~122.2 cm，花序直径12~14 cm，第一朵花出现在4月中旬或5月上旬，开花持续时间25~31 d。因此，认为西西里密、额毛和格斗者这3个花葱品种可作为春夏季花卉在湖南地区种植。%In order to enrich bulbous flower species of Hunan, 4 cultivars ofAllium Giganteum were introduced from Holland. The phenological phase, ornamental characteristics and growth status of 4 cultivars ofAllium Giganteum in Hunan were investigated and analyzed. The results showed that 4 cultivars had strong cold tolerance. The seedling stage was in February, the seedling rate was above 85%, and the leaf expansion period was from March 15th to 27th. In addition to “album” 3 cultivars had good ornamental character with big and colorful lfower. 3 cultivars had only 1 lfowering stem with 80.5-122.2 cm in length, the diameter of inlforescence was 12-14 cm. The ifrst lfower’s blossom period was in mid April or early May and groups’ blossom time was 25-31 days. We could concluded that 3 cultivars ofAllium Giganteum such as Sicily, Forelock and Gladiator could be cultivated as an spring and summer lfower in Hunan.
