Abstract: 【Objective】 In view of the problem of the quality decline caused by the incomplete coloring and unreasonable use of regulators in Table grape in Xinjiang, the research object of this study was to compare the advantages and disadvantages of the independent R & D regulator with the marketed regulator and foliar fertilizer, and to study the influence of the independent R & D foliar regulator on the coloring and quality of grape. 【Methods】 In this study, the effects of spraying different regulators and foliar fertilizer on the coloration and quality of grape were studied by using grape ('Red Earth') as material and single -factor random block test design. 【Results】 Compared with other treatments, spraying the self-developed foliar conditioner could effectively increase the color parameters of grapes, enhance the accumulation of anthocyanins, gradually increase the activity of coloring-related enzymes, increase the vertical and horizontal diameter of fruits, and increase the swelling rate at a high level. With the increase of the content, the hardness of the peel decreased with time. 【Conclusion】 Compared with the market regulator and foliar fertilizer, all the indexes were in high level, which could effectively improve the coloration and quality of grape fruit. Compared with marketing regulator and foliar fertilizer, all the indexes of leaf regulator developed independently are in high level, which can effectively improve the color and quality index of grape fruit.

摘要： 【目的】 对比自主研发调节剂与市售调节剂及叶面肥的优劣,研究自主研发叶面调节剂对葡萄着色及品质的影响。【方法】 自主研发的叶面调节剂为研究对象,采用田间小区试验,以葡萄红地球为材料,采用单因素随机区组试验设计,分析喷施不同调节剂及叶面肥的条件下对葡萄着色及品质指标的影响。【结果】 喷施自主研发叶面调节剂相比于其它处理可有效调高葡萄的色泽参数,加强花色苷的累积,着色相关酶活性逐渐增加,果实纵横径增加,其膨大率处于较高水平,可溶性固形物含量提高,果皮硬度随时间变化而下降。【结论】 自主研发叶面调节剂相较于市售调节剂与叶面肥,各项指标均处于较高水平,可有效提高葡萄果实着色及品质指标。
