生物刺激素“秋实皆”和“思甜”对阳光玫瑰果重和果实均匀度的改善

Effects of Biostimulants “Qiushijie” and “Sitian” on Grape “Shine Muscat” Weight and Size Uniformity Improvement

摘要: 近年来，“阳光玫瑰”葡萄近因过度追求亩产量，加上田间管理不当，果实品质量下降，市场价格急剧下滑等问题，在全国各地引起关注。本研究使用生物刺激素组合，包括含多肽类和生物碱的产品“秋实皆”和“思甜”进行冲施和叶面喷施，调查其对果品质量改善的效益。结果显示，亩冲施5公斤“秋实皆” + 叶喷300倍“思甜”的试验组，平均单果重可达12.6克，较对照组高出1.1克。试验组比对照组平均纵径多出5.8%的拉长率，维持平均果形指数达到1.1以上。糖度方面，试验组果串顶部和底部果实，均比对照组高出1~2度。产品方案对“阳光玫瑰”具有增重、改善外观和糖度的效益。

Abstract: Fruit quality decline in “Shine Muscat” grapes due to excessive yield per acre and improper field management is noteworthy issues in recent years for grape farm in China. 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.
