Abstract:

To study the climatic conditions for planting Shine-Muscat in Xianyang and determine the planting suitability, using meteorological data such as daily temperature, precipitation, sunshine, and weather phenomena from 12 national basic meteorological stations in Xianyang City, analysis and research were conducted to screen the major climate indicators affecting the cultivation of Shine-Muscat in the Xianyang Region. Based on the fuzzy comprehensive evaluation method, membership functions were constructed for different climate indicators to evaluate and determine the weight coefficients of each climate indicator. Through fuzzy synthesis, a comprehensive evaluation of the suitability for planting Shine-Muscat in different regions was obtained. GIS technologies were employed to achieve a refined zoning of climatic suitability for the cultivation of Shine-Muscat in Xianyang City, and the climatic conditions for commercial cultivation of this variety were determined. The results showed that most areas in Xianyang City met the climate conditions for planting Shine-Muscat, but there were significant differences in the degree of suitability. The most suitable areas were mainly concentrated in the central and southern parts of Liquan, the central part of Qianxian, most of Jingyang, the central and southern parts of Sanyuan, Qindu, and the northern part of Weicheng. The suitable areas were the rest of the southern counties, as well as the southern regions of Yongshou and Chunhua. The generally suitable areas were Changwu, the central and northern parts of Yongshou, the central part of Chunhua, most of Binzhou, and the western part of Xunyi, while the unsuitable areas were the eastern part of Xunyi, the northern part of Chunhua, and the southwestern part of Binzhou. The refined zoning results of Shine-Muscat are basically consistent with the current planting situation in the local area, but there is still room for optimization and adjustment, as well as significant potential for quality improvement and yield increase. This research method can provide scientific reference basis.
