This study conducts experiments of biostimulants, including products containing polypeptides and alkaloids, namely “Qiushijie” and “Sitian”, for ground flooding and foliar spraying. Investigation on their effectiveness in improving fruit quality was done. The results showed that, groups flooding with “Qiushijie” combined with foliar application 300 times dilution of “Sitian” displayed average single fruit weight of 12.6 grams, which was 1.1 grams higher than the control group. The experimental group also exhibited an average elongation rate of 5.8%, higher than the control group, maintaining a fruit shape index of above 1.1. In terms of sugar content, both the top and bottom fruits in the experimental group displayed sweetness levels that were 1~2 degrees higher than those in the control group. The combination of these products demonstrated positive benefits for “Shine Muscat” grapes on weight, fruit size, and fruit sweetness.展开更多
