- 摘要:
- 以毛桃砧3年生“春美”为试材,研究了不同时期春梢摘心（4月下旬至7月下旬）对新梢生长及成花的影响。结果表明：只有在4月下旬新梢生长初期（15 cm左右）时摘心，才能显著降低春梢粗度和第1次副梢的数量；各个时期摘心对第1次副梢的粗度和长度无显著影响。摘心时期对春梢成花作用不显著；除4月下旬（春梢15 cm时）摘心处理外，其它各处理促进第1次副梢成花的效果均显著。春梢生长前期(5月及之前)摘心能显著地降低第1次副梢的盲梢率。摘心与不摘心的春梢上第2次副梢的盲梢率均较高。
- Abstract:
- The effect of top removal of spring shoots in their different growth stages （from late April to late July） on growth and flower bud formation of new shoots were studied with 3-year-old peach variety of ‘Chun Mei’ on the peach rootstock as experimental materials.The results showed that top removal could inhibited their diameter increase and reduce the secondary shoot number at the early stage of growth in late April （at the length of spring shoots about 15 cm).Top removal at each growth stage had no significant effect on the diameter and length increase of the secondary shoots.All top removal treatments had no significant effect on the flower bud formation of spring shoots，and the treatments except at late April(top removal at the length of spring shoots about 15 cm) could significantly promote the flower bud formation of the secondary shoots.Top removal at the early growth stage of spring shoots(before late May) could significantly reduce no bud shoots rate of the secondary shoots.Top removal or not had high no bud shoots rate of the third shoots.
