中文摘要	在干旱区灌溉条件下,探索平欧杂种榛’达维’合理的修剪措施,为新疆’达维’的优质高产栽培技术提供科学参考。以新疆乌鲁木齐安宁渠5年生的’达维’为研究对象,比较不同年龄枝条(1年生和2年生)在不同修剪强度下(对照、轻度、中度、重度)对新梢生长、叶片特性、光合及结实特性的影响。结果表明,1年生枝条修剪的新梢生长和叶面积均高于2年生。1年生枝条修剪显著影响了叶片各光合特征参数,其中,轻度修剪的净光合速率和气孔导度较对照分别显著提高25.09%和40.00%,重度修剪则降低11.80%和10.37%。与1年生枝条不同,2年生枝条修剪对叶片各光合特征参数均未产生显著影响。1年生枝条修剪后的坐果率、单株结果数和单株产量均高于2年生。与对照相比,1年生枝条轻度和中度修剪的单株产量分别提高26.35%和18.27%。2年生枝条修剪则显著降低了单株产量,各修剪强度较对照平均降低45.47%。1年生枝条轻度修剪促进了新梢生长,增强了叶片光合能力,提高了单株结果数和产量。因此,在新疆干旱区特殊生态环境条件下,对’达维’的1年生枝条采用轻度修剪的效果最佳。
英文摘要	In order to explore reasonable pruning measures for the cultivation of Corylus heterophylla*Corylus avellana(’Dawei’) under irrigation in the arid area,and to provide scientific references to harvest fruit with high quality and yield,trees of 5-year-old ’Dawei’ was selected as the test materials in Anningqu of Urumqi,Xinjiang.Branches with different ages (1- and 2-year-old) were subjected to different pruning intensities (no prunning,light,moderate,and heavy pruning) on the new shoot growth,leaf characteristics,photosynthetic and fruiting characteristics were examined.The results showed that the new shoot growth and leaf area in 1-year-old branch pruned were all greater than 2-year-old branch pruned.The effects of the pruning on the leaf photosynthetic characteristic parameters of 1-year-old branches were significant.For example,the leaf net photosynthetic rates and stomatal conductance under light pruning were significantly improved by 25.09% and 40.00%,respectively,compared to the control (no pruning),while decreased by 11.80% and 10.37% under heavy pruning.In contrast to the pruning on 1-year-old branches,there was no significant difference in leaf photosynthetic characteristic parameters when the 2-year-old branches were pruned with different intensities.The fruit setting rates,single plant fruit number and yields under 1-year-old branch pruning were all higher than 2-year-old branch pruning.Compared with the control,light and moderate pruning on 1-year-old branches improved the single plant yields by 26.35% and 18.27%,respectively.However,different pruning intensities on 2-year-old branches significantly decreased the average yields of single plant by 45.47%,when compared to the control.Overall,light pruning on 1-year-old branches promoted the new shoot growth,enhanced the leaf photosynthetic capacity,and increased the single plant fruit number and yields.Therefore,under the unique ecological environment in arid area of Xinjiang,it was recommended to conduct light pruning on 1-year-old branches of ’Dawei’.
