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(15cm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15cm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。
The peach anvil 3 years “Spring America ” was used as material to study the effects of different periods of spring shoot topping (growth from late April to late July) on shoot growth and flower formation. The results showed that only in the beginning of April new shoot growth (15cm or so) topping, in order to significantly reduce the spring shoots and the number of the first secondary shoot; the first time in each period topping the first secondary tip of the roughness and length of Significantly affected. During the period of pinching, there was no significant effect on the flower bud formation of spring shoots; except for the topping treatment in late April (spring shoot 15 cm), the other treatments promoted the first shoot shoots to have a significant effect. Spring shoot growth early (May and before) topping can significantly reduce the rate of the first shoots of the shoots. Topping and not picking the spring tip of the second tip of the blind shoot rate are higher.
