分别用温室育苗、春季露地播种和秋季播种等繁殖方式对野生紫花地丁进行试验,观察其物候期及适应性。结果表明:温室育苗繁殖和秋播繁殖栽培的紫花地丁出苗率高,出苗快而整齐,开花早;而春播紫花地丁出苗缓慢且不整齐,出苗率低,开花晚,花期短。因此,乌鲁木齐地区以温室育苗栽培和秋季播种繁殖栽培紫花地丁最为适宜。紫花地丁叶形、花色美观,地面覆盖效果好,耐阴,适合本地区生长,各方面抗性较强,可粗放管理,是难得的优良地被植物,值得在乌鲁木齐地区大力推广。
Wild Vitex gmelini was tested by seedling raising in greenhouse, sowing in spring and seeding in autumn, respectively. The phenological period and adaptability were observed. The results showed that: the seedlings of greenhouse cultivation and autumn planting propagation purple seedling emergence rate is high, quick and neat emergence, early flowering; and the spring sowing Vitex negundo emergence is slow and irregular, low rate of emergence, late flowering, flowering short. Therefore, it is most suitable for cultivation of Viola yedoensis in greenhouse cultivation and autumn planting in Urumqi. Violaceum leaf shape, beautiful color, good ground cover, shade tolerance, suitable for the growth of the region, all aspects of resistance, can be extensive management, is a rare fine ground cover, it is worth vigorously promote in Urumqi.
