海南岛裸花紫珠种质资源调查报告

Investigation Report on the Callicarpa nudiflora Hook. et Arn. in Hainan Island

通过查阅文献、走访药农、实地调查等方式对海南岛裸花紫珠野生及栽培资源进行了调查,结果显示,裸花紫珠野生资源虽在全岛大部分地区均有分布,但蕴藏量较小。此次调查共收集了96份野生繁殖材料,分布于海南岛14个县市。不同的气候条件对裸花紫珠的生长影响较大;裸花紫珠的栽培始于2006年前后,目前栽培资源主要分布于白沙县、五指山市等地区,2016年全省栽培总面积约为493 hm^2,产量约为962 t(干品),其中以白沙县种植面积最大(约333 hm^2),年产量最高,为650 t(干品)。虽然裸花紫珠的种植已成一定的规模,但目前仍然缺乏规范化的种植技术,生产管理仍处于粗放无序的状态,且品种选育工作薄弱,并无优势品种出现。

By consulting relevant literature, visiting herbalists, field survey and so on, the Wild and cultivated resources of Callicarpa nudiflora Hook. et Arn. in Hainan were investigated. The results showed that, although the wild resources of C. nudiflora were distributed in most parts of the whole island, the amount of reserves was small. 96 wild reproductive materials were collected, which distributed in 14 counties and cities of Hainan province. The growth of C. nudiflora was greatly affected by the climatic conditions. The cultivation of C. nudiflora began around 2006. Currently cultivated resources are mainly distributed in areas such as Baisha, Wuzhishan, and so on. In 2016, the total cultivated area of the province was about 493 hm2, with a yield of about 962 tons. The largest planting area was in Baisha county（ about 333 hm^2 ）, with the highest annual yield（650 tons of dried products）. Although the planting of C. nudiflora had grown to a certain size, there was also lack of standardized cultivation technical guidance, and the production management was still in a rough state. The progress of variety breeding work was also slow. There was still no advantage cultivated varieties.
