| 采用不同种源的五指毛桃 Ficus hirta 种苗，开展种植株行距、植穴规格、施肥等引种栽培试验。结果显示：（1）来自广东河源和广西灵山两个种源 2.5 年生的造林成活率达到 98% 以上；两个种源树高、地径和冠幅、根生长量，以及地上部分鲜质量、地下部分鲜质量、干质量差异均不显著。（2）不同植穴规格对 2.5 年生五指毛桃冠幅极显著，对树高影响不显著，对地上部分的质量和地下部分质量的影响显著；植穴规格为 60 cm×60 cm×50 cm 植株的地上部分和地下部分鲜质量分别比试验群体平均值提高了 48.90% 和 32.64%。（3）不同的种植株行距处理和不同的基肥处理对 2.5 年生五指毛桃的树高、地径和冠幅，对地上部分的枝、叶、果和地下部分的主根、侧根的鲜质量的影响均不显著，小株行距 0.8 m×0.8 m 单位产量大于其他两种较大株行距。（4）五指毛桃 11 个指标间均呈现极显著水平。因此适当增大植穴规格、合理提高种植密度和控制树高、增大冠幅是提高五指毛桃产量的重要措施。 |

| Abstract: |
| Ficus hirta seedlings from different provenances were used t to experiment with introduction and cultivation techniques such as row spacing, hole specification, and fertilization. The results showed: (1) The afforestation survival rate of 2.5-years-old seedlings both from Heyuan in Guangdong and Lingshan in Guangxi have reached more than 98%; the differences among the tree height, ground diameter, crown width, root growth, fresh weight and dry weight were not significant. (2) Different hole specifications of 2.5-year-old F. hirta had a significant impact on the growth of crown widthand significant effects on the weight of overground and underground parts but had no remarkable effects on tree height. The fresh weight of the aboveground and underground parts of the 60 cm×60 cm×50 cm planting hole was 48.90% and 32.64% higher than the average value of the test population, respectively. (3) The different treatments for hole spacing and base fertilizer did not significantly affect the tree height, ground diameter and crown widths of 2.5-year F. hirta, as well as the underground branches, leaves, fruit and the fresh weight of the main root and lateral root. The unit yield of small plants with row spacing of 0.8 m×0.8 m was higher than that of the other two larger row spacing. (4)The relationship among 11 indexes to F.hirta presented an extremely significant level. Therefore, appropriately expanding the planting hole specification, increasing the planting density and controlling the tree height to increase the crown width are three important measures to improve the yield of F. hirta. |
