摘　　要：试验设置4个修剪节位及3个修剪时期,探讨了春季的修剪节位及修剪时期对四季蜜芒枝梢生长状况及反季节成花的影响。结果表明:从修剪节位来看,B处理(剪至蜜节芽上端)的一次梢抽梢率96.7%,剪口平均枝量2.2条,枝条平均长度19.25 cm,枝条平均叶片数9.31张;二次梢抽发率83.3%,8月中旬成花率67.1%,其各项指标是所有处理中最好的;从修剪时期来看,3月22日修剪的,二次梢的抽发率最高,达到78.0%,修剪越迟,二次梢抽发率越低;成花率以4月7日修剪的最高,达到68.0%。这说明4月7日在密节芽上端的短剪(B处理)为最佳组合。In order to research the effects of different pruning time and gnarls on shoots growing and flowering formation rate in off-season of Sijimi-mango trees,the test designed 4 different pruning gnarls and 3 different pruning dates. The results were as follows： Analyzed from the gnarls of pruning,the sprouting rate of first shoots of the treatment B pruning up cluster bud up to 96. 7%,the average sprouting number of first shoots up to 2. 2,the average length of first shoots up to 19. 25 cm and average number of leaf on each shoot up to 9. 31 pages; the sprouting rate of second shoots up to83. 3%,the flower formation rate up to 67. 1% in middle august; among all treatments,all indexes of treatment B were the best. Analyzed from the different pruning dates,the highest sprouting rate of second shoots（ up to 78. 0%）was obtained on branches which pruning on March 22 and it was more and more lower with the delay of pruning time,the highest rate of off-season flower formation rated up to 68. 0%. In conclusion,the treatment B pruning on April 7was the best combination.
