用重、中、轻3种不同强度修剪处理调节香蜜杨桃产果期,试验结果表明:随着修剪程度的加重,始花时间分别推迟约100d、140d,第一批果实成熟时间推迟约90d、120d;提高了当年促生梢开花座果枝条的比例,增加产量;提高了产果后期产量的比例,有效地调整产量结构,显著提高了产值。
用重、中、輕3種不同彊度脩剪處理調節香蜜楊桃產果期,試驗結果錶明:隨著脩剪程度的加重,始花時間分彆推遲約100d、140d,第一批果實成熟時間推遲約90d、120d;提高瞭噹年促生梢開花座果枝條的比例,增加產量;提高瞭產果後期產量的比例,有效地調整產量結構,顯著提高瞭產值。

Carambola tree was treated with different pruning intensity to adjust its fruit setting. The results have revealed that the early flowering season was delayed up to 100 days and 140 days under the treatment of heavy pruning compared with the oth- er two treatments respectively. Meanwhile, the first fruit maturation was delayed around 90 or 120 days which helped both in increasing yield and economic value.
