摘要: 对柠檬春花期新梢进行抹除(抹梢);修剪柠檬花期过密花枝,同时抹除抽发的新梢(抹梢+修剪),统计分析有叶枝梢花量、无叶枝梢花量、有叶果量、无叶果量、枝梢叶片数量、单株产量。旨在研究抹梢和修剪处理对柠檬春花秋熟果花果调控的影响,为提高柠檬产量及柠檬的花期调控理论提供科学依据。结果表明:不同处理间柠檬带叶枝梢花量和无叶枝梢花量的差异均不显著;不同处理对柠檬有叶果量和无叶果量影响较大。生理落果完成后,不同处理间有叶果量和无叶果量差异显著,均为修剪+抹梢处理最多,抹梢处理次之,对照最少;不同处理对枝梢叶片数量的影响较小,差异不显著;不同处理间柠檬单株产量差异均达到显著或极显著水平。同一年度不同处理单株产量大小依次为:修剪+抹梢>抹梢>对照,2010、2011年抹梢处理分别比对照增加45.0%、33.8%,修剪+抹梢分别比对照增加86.2%、71.9%。综合考虑,柠檬春花果修剪+抹梢调控效果最好。

Abstract: In order to provide scientific basis for yield increase and regulating of blooming time of lemon, the authors studied the regulating of blooming time by pinching off shoots and pruning branches. A field experiment was carried out by pinching off shoots and pruning branches in the blossom. The number of flowers on branch with leaves and flowers on branch without leaves, the number of young fruits on branch with leaves and without leaves, the number of leaves on branch and individual yield were used for statistical analysis. The results indicated that the number of flowers on branch with leaves and flowers on branch without leaves had no significant difference, and different methods had significant impact on young fruits on branch with leaves and without leaves. The number of young fruits on branch with leaves and without leaves were significantly different compared with the control treatment when the physiological fruit drop completed, the maximum was pruning erasing-top, the second was erasing-top and the least was control treatment. Different methods had less effect on the number of leaves on branch and no significant difference. The individual yield was significantly different compared with the control treatment, and the individual yield order was pruning erasing-top, erasing-top, control treatment in the same year. The individual yield of erasing-top increased by 45.0% and 33.8% compared with that of CK in 2010, 2011, the individual yield of pruning erasing-top increased by 86.2% and 71.9%. In overall consideration, pruning erasing-top was the best treatment.
