在山西古县,对沙棘13个种源的早实丰产性进行了研究。结果表明,造林后第3年和第4年,沙棘不同种源的结果特性表现出差异显著。应用综合评价指标筛选出涿鹿、西吉、蔚县、古县为沙棘早实丰产优势种源。该试验在古县条件下为营造沙棘果用林在种源选择上提供了依据。
In the ancient county of Shanxi Province, 13 provenances of Hippophae rhamnoides were studied for their high yield. The results showed that the results of different provenances of seabuckthorn showed significant difference in the third year and the fourth year after afforestation. Applying the comprehensive evaluation indexes to screen Zhuolu, Xiji and Yuxian counties, the ancient county is the seabuckthorn pre-mature high yield provenance. The experiment provides the basis for selecting the provenance of seabuckthorn fruit trees under the condition of ancient county.
