由于“巨峰”葡萄种植面积的迅速发展和单产的提高,随之出现葡萄果实着色不佳和品质下降等问题,特别是高产葡萄园这些问题更为突出,从而影响了葡萄销售和商品价值,这是果农们急需解决的一个问题。 1987年以来,上海市农业科学院植物保护研究所沈岳清副研究员,针对葡萄生产上存在的问题,开展了“葡萄着色增糖剂”的研究,经反复试验示范,不断改进配方,使之成为较理想的制剂。 据试验,在葡萄果实达到充分软化并开始转色时使用“葡萄着色增糖剂”,在用药后5、10、15天,
Due to the rapid development of “Kyoho” grape planting area and the increase of yield, the ensuing problems such as poor coloring and poor quality of grape fruits, especially the problems of high-yield vineyards are more prominent, which affects the sales of grapes and the value of commodities, which Is a problem that farmers need to solve urgently. Since 1987, Associate Professor Shen Yuqing, Institute of Plant Protection, Shanghai Academy of Agricultural Sciences, has carried out research on “grapes of pigmented sweeteners” in light of the problems in grapes production. After repeated experiments and demonstrations, the formulation has been continuously improved to make it an ideal Of the formulation. According to the test, when the grape fruit is fully softened and the color is changed, the grape coloring sugar-sweetener is used. At 5, 10, 15 days after the treatment,
