随着巨峰葡萄种植面积的扩大和单产的提高,出现果实着色不佳和品质下降等问题,高产葡萄园更为突出。自1987年以来,我们开展了改善葡萄着色和品质的研究,筛选出“葡萄着色增糖剂”。经本市和江苏、浙江、河北、辽宁、山东、陕西、安徽、山西、福建、北京等10余个省市的应用表明:巨峰葡萄应用葡萄着色增糖剂后,对提早成熟和改善品质有极好的效果。据上海市农业局植保植检站试验,在喷葡萄着色增糖剂后3、6、10和13天,葡萄着色度分别达25.1％、53.7％、76.5％和93.3％,而同期未喷的着色度仅 With the expansion of Kyoho grape planting area and yield improvement, fruit coloring and poor quality problems such as the emergence of high-yield vineyards are more prominent. Since 1987, we have conducted research to improve the coloring and quality of grapes and screened “Grape Pigment Sweeteners.” The application of more than 10 provinces and municipalities including Jiangsu, Zhejiang, Hebei, Liaoning, Shandong, Shaanxi, Anhui, Shanxi, Fujian and Beijing shows that the application of grapes to the Kyoho grapes improves early maturity and quality improvement Excellent results. According to the experiment of plant protection and phytosanitary station of Shanghai Municipal Bureau of Agriculture, the shades of grapes reached 25.1%, 53.7%, 76.5% and 93.3% at 3, 6, 10 and 13 days after grapes were sprayed with colored sweeteners, Coloring only
