Research and Application of Key Techniques for Leaf Picking and Fruit Thinning of Shiraz Grape in Huailai Production Area

Abstract

With the development of the times and the people’s yearning for a better life, wine products are required to keep pace with the times. Homogeneous and popular products are no longer attractive. The research direction is to pursue the essential characteristics of wine and explore the regional advantages of grape varieties and production areas. “Three parts of technology, seven parts of raw materials”, that is to say, under the same winemaking process conditions, the quality of wine grape directly affects the quality of wine. Huailai is located in the advantaged natural conditions, making Huailai one of the most suitable grape producing areas in China. Taking the wine grape variety Shi-raz in Huailai production area as the research object, through the application of leaf picking and fruit thinning and yield control technology in different periods and degrees, the grape ear can fully receive the light, effectively control the yield of Shiraz grape, and finally realize the improvement of Shiraz grape and wine quality.
