Abstract: In order to improve the winter corms reproduction methods of gladiolus in South China, reproductive experiments were conducted by using different size of gladiolus cormels and different sowing density. Results showed that the size of gladiolus corms harvested was affected by the size of sowing cormels and sowing density. When the circumference of sowing gladiolus cormels was 2.3—3.1 cm, and the sowing density was 400 grain·m-2, the numbers of commercial corms (circumference >6 cm) and cormels were the largest (255 grain·m-2 and 9813 grain·m-2). When the circumference of sowing gladiolus cormels was 2.3—3.1 cm, and the sowing density was 200 grain·m-2, the percentage of harvested commercial corms were the highest, upto 76.38%.

摘要： 为不断改进唐菖蒲Gladiolus gandavensis冬季在我国南方的种球繁殖方法和技术，采用不同大小籽球及播种密度进行繁殖试验。结果表明，播种籽球大小及播种密度可影响收获种球大小及分布。周径2.3～3.1 cm籽球及400粒·m-2播种密度是最佳处理组合，收获的商品球(周径＞6 cm)数量最多，达255粒·m-2，收获籽球的数量也最多，达9813粒·m-2，重量达875.3 g·m-2。周径2.3～3.1 cm籽球及200粒·m-2播种密度处理组合收获的商品球占比最高，达76.38%。
