以切花康乃馨新品种“复古”原种一代枝条为试材,进行了不同密度(株行距)的扦插繁育对比试验,以求得最佳扦插密度。试验证明,以3 × 5 cm (株行距)的扦插密度最佳,存活率达100%,根系发达,色呈乳白色,株高12.5 cm,叶片数6对,叶色深绿,无病害发生。Using the original branches of the new varieties of cut flower carnation, the first generation of the original species of “retro” was used as the test material, and a comparison test of cutting breeding of different densities (plant spacing) was carried out to obtain the best cutting density. The experiment proves that the cutting density of 3 × 5 cm (plant spacing) is the best, and the survival rate is 100%. The root system is well developed, the color is milky white, the plant height is 12.5 cm, the leaves are 6 pairs, the leaves are dark green, and there are no diseases and pests.
