以 8年生巨峰葡萄为试材 ,采用叶面喷施方法 ,研究了植物核酸营养素对葡萄生育的影响。结果表明 ,喷施植物核酸营养素可促进葡萄黄叶转绿、叶片增厚、枝条成熟和提高果实品质。同对照相比 ,平均单粒重增加 1 9.1 %,可溶性固性物含量提高 2 .1个百分点 ,亩产提高1 8.3%,亩产值提高 2 5.7%
Taking 8-year-old Kyoho grapes as test material, the effect of plant nucleic acid nutrients on grape growth was studied by foliar spraying method. The results showed that the application of plant nucleic acid nutrients can promote yellow green leaves, thickened leaves, mature branches and improve fruit quality. Compared with the control, the average single grain weight increased by 9.11%, the soluble solid content increased by 2.1 percentage points, increased by 18.3% per mu and increased by 25.7%
