| 摘 要： | 连续３年对庆丰和燕红桃树进行研究,结果表明,与传统短枝修剪技术相比较,长枝修剪后,树体丰产性能好、产量高,果实着色好,且在大多数情况下,果实可溶性固形物含量高,提高了品质。长枝修剪对果实生长的影响与品种的成熟期有关,早熟品种庆丰无显著作用,晚熟品种燕红采收时平均果重显著增加。采用长枝修剪技术,能显著地提高花芽的质量,尤其是枝条下部的花芽质量,从而可增强对晚霜冻害的抵抗能力,还对在长枝修剪条件下树体保留一年生枝的长度和姿势与果实大小的关系进行了研究,并对长枝修剪早果、丰产、稳产和优质的生物学基础和果园管理特点进行了讨论表示处理间存在Ｐ＝０．０１差异水平。２．２开花物候期修剪方式对树体初花期及花期待续时间无影响。１９９４年,长枝修剪和短枝修剪的庆丰、燕红的花期分别均为４月１４～１８日和４月１４～１９日。但是,开花动态在处理间存在差别。在初花期（４月１４日和１５日）长枝修剪树花朵开放率显著地高于短枝修剪树。另外,长枝修剪处理树体之间开花较整齐（变异系数小）。２．３坐果和产量１９９３年花期连续低温,经观察短枝修剪早久保和大久保受到严重冻害,坐果率低,负载量严重不足,而长枝修剪树对低温抵抗力强,坐果率显著高,从而获得?

| Abstract: | The experiment was carried out during 1 992- 1994 on " Qing-feng" and " Yan-hong" peach trees. Whencompared with traditiunal " short pruning" ,the yield and fruit quality were improved on the trees pruned by " long pruning" (LP). The effect of long pruning on fruit growth depended upotn the mature date : average fruitweigth was increased for " Yan-hong" -a latc mature cultivar while no effect was observed for the early ma-ture cultivar " Qing-feng" . The quality of fruit bud on the LP trees was high , this may explain the higher resis-tance of flowers on LP trees during late spring as compared with the traditional pruning technique. Morenver ,fruit sise at harvest was studied in relation to the length and tlne orientation of 1-year-old wood and finally thesome cultural techniques in orchard management are discussed whent using the LP technique , |
