| 中文摘要: |
| 在桂林市农业科学研究所以10年生、单层树形丰水为试材，开展丰水春夏梢自然生长试验，以抹除内膛春夏梢和对春夏梢摘心做比较，研究丰水春夏梢自然生长对成花及产量的影响。结果表明，丰水春夏梢自然生长可使树体枝叶总量增加，其内膛成花枝率为32.6%，次于摘心处理的44.9%成花枝率；其产量在三个处理中最高，每667㎡达2324㎏，比抹除春夏梢处理的产量多415㎏；可溶性固形物差异不明显。综合产量、品质、收入与支出成本比较，桂北地区单层树形丰水春夏梢自然生长亦能达到较好的成花坐果效果。 |
| 英文摘要: |
| With ten-year-old single tree form Hosui Pear as the test material and two methods—spring summer shoots erasing bore and spring summer shoots pinching as controls, the experiment about the natural growth of spring summer shoots of Hosui Pear was taken to study the effects of the natural growth of spring summer shoots on the flower formation and fruit produce of Hosui Pear in Guilin Agricultural Science Research Institute. The result showed that the natural growth of spring summer shoots could increase total tree branch leaves. And the bore flower formation rate was 32.6%, less than the 44.9% with spring summer shoots pinching. The produce, 2324kg per 667㎡, 415kg more than that erasing spring summer shoots, turned out to be the highest produce among the three kinds of treatments. But there was no significant difference in soluble solids. Comparing produce, quality, income and cost, the natural growth of spring summer shoots could get better effect than the other treatments on flower formation and fruit setting of single tree form Hosui Pear in Northern Guangxi Region. |
