摘　　要：以‘着色香’葡萄为试材,设置不同枝果比,通过对成熟期叶片光合能力、果实经济性状、枝条养分物质含量和花芽分化质量等指标进行分析,研究不同枝果比对‘着色香’葡萄生长发育的影响,以期确定‘着色香’葡萄的最佳负载量。结果表明:‘着色香’最佳枝果比1∶1,最高不超过2∶3。适宜的负载量有助于优质果品的生产和连年丰产;负载量过高,果实品质降低,也不利于叶片、枝条的生长和花芽分化。Taking‘Zhuosexiang’grapes as the test materials,set different branch fruit ratios were seting,and the indicators such as photosynthetic capacity of mature leaves,economic traits of fruits,nutrient content of branches,and quality of flower bud differentiation were analyzed,the effects of different branch fruit ratios on the growth and development of‘Zhuosexiang’grapes were studied,in order to determine the optimal loading capacity of‘Zhuosexiang’grapes.The results showed that the optimal branch fruit ratio for‘Zhuosexiang’was 1∶1,with a maximum of no more than 2∶3.Appropriate load capacity helped to produce high-quality fruits and achieve continuous high yields.If the load was too high,the quality of the fruit would decrease,which was not conducive to the growth of leaves and branches,as well as flower bud differentiation.
