| 中文摘要: |
| 通过调查荔枝苗圃杂交苗的生长情况，研究了适用于荔枝选种圃的株行距。 结果表明，荔枝杂交苗的生
长速度不同，1 年生和 2 年生荔枝实生苗在株高尧干粗、冠幅和抽梢次数方面均存在较大差异：播种 1 年后密度为 70
株/m2以上的植株表现偏密，苗圃密闭严重；播种 2 年后密度为 53 株/m2的植株也表现出严重密闭；绝大部分 2 年生
荔枝杂交苗的冠幅为 25~45 cm，根据荔枝种子大小分区规划选种圃并结合土地充分利用等因素，荔枝选种圃的合理
株行距为 9~16 株/m2。 |
| 英文摘要: |
| The reasonable planting space for litchi selective nursery was studied by investigating the growth of litchi
hybrids. The results showed that the litchi hybrid progenies were different in growth speed, and there were some differences
in plant height, diameter of trunk, crown diameter and sprouting times between annual and two-year old hybrid progenies.
The hybrid progenies with density above 70 plants/m2 were dense one year after sowing, and hybrids with density of 53
plants/m2 were also airtight two years later. The canopy of most two -year old hybrid progenies was 25 cm -45 cm.
Therefore, the selective nursery should be divided into some zones according to the size of seeds, and the reasonable
planting space for litchi selective nursery was 9-16 plants/m2, combined with the utilization rate of land and other factors. |
